SEQUENTIAL MULTIPORT FUEL INJECTION (SFI–V8) A1

CIRCUIT OPERATION 1

CIRCUIT OPERATION

Sensors

Engine Fuel Temperature Sensor (X128)

This is a resistive sensor, located on the fuel rail andmeasuring the temperature of the rail rather than thefuel. The signal is used to increase the injectionpulse times when undergoing hot restarts. When thefuel is hot, vaporisation occurs in the rail and a“bubble” could form within the injectors. Increasingthe pulse times flushes the “bubbles” away and coolsthe fuel rail with fuel from the tank.

Knock Sensors (X309, X310)

The knock sensor is a “Piezo–electricaccelerometer,” i.e. it produces an output voltageproportional to mechanical vibration produced by theengine. The Engine Control Module (ECM) (Z132)receives the signal, filters out any noise andcalculates if the engine is knocking. Due to the camand crank signals supplying information regardingthe position of the engine in it’s cycle, the ECM(Z132) can work out exactly which cylinder isknocking and retards the ignition on that particularcylinder until the knock disappears. It then advancesthe ignition again to find the optimum ignition pointfor that cylinder for those conditions (i.e. fuel type,air temperature etc.). The ECM (Z132) will be able toadjust cylinder timing for knock simultaneously, sothat all eight cylinders could have different advanceangles at the same time.

Coolant Temperature Sensor (X126)

A temperature dependant resistive metal componentis the major constituent of this sensor, i.e. theresistance of the metal strip varies quiteconsiderably with temperature. The coolant sensorsignal is vital to correct engine operation, as theinjected fuel quantity is dependant upon the enginetemperature, i.e. richer mixture at low temperatures.

Intake Air Temperature Sensor (X311)

This is a resistive sensor, i.e. the change inresistance is related to change in air temperature.The signal from the Intake Air Temperature Sensor(X311) is used to retard the ignition timing if the airtemperature rises above 55C.

Crankshaft Position Sensor (X250)

The Crankshaft Position Sensor (X250) is a veryimportant sensor, as the signal it produces tells theECM (Z132) that the engine is turning, how fast it isturning and at which stage the engine is at in the

cycle. The crank signal is the basis of the fuelinjection and coil firing times.

Camshaft Position Sensor (Z262)

This is a Hall Effect sensor producing one pulse forevery two revolutions. The Signal is used in twoareas: Injector timing corrections for fully sequentialfuelling and active knock control.

Camshaft operation is essential to continue normalignition, i.e. actuate the fuel injectors in the normalsequential order, timing the injection correctly withrespect to top dead centre. In this way the sequentialfuelling will either be correct, or one enginerevolution out of synchronisation.

SEQUENTIAL MULTIPORT FUEL INJECTION (SFI–V8)A1

CIRCUIT OPERATION2

Mass Air Flow Sensor (X105)

The sensing element of a Mass Air Flow Sensor(X105) is a “hot wire anomometer” consisting of twowires; one heated, one not. The air flows across thewires, cooling the hot wire and thereby altering itsresistance. The ECM (Z132) measures this changein resistance and so calculates the amount of airflowing into the engine.

If the Mass Air Flow Sensor (X105) fails, the enginewill start and then die as the engine reaches 550 rpmbefore the ECM (Z132) looks for the Mass Air FlowSensor (X105) signal.

Throttle Position Sensor (X171)

This sensor is a variable resistor. The signal informsthe ECM (Z132) of the actual position of the throttleplate. Failure of the Throttle Position Sensor (X171)will result in poor idle and lack of throttle response. Ifthe Throttle Position Sensor (X171) fails in the“closed” mode, then the engine will only rev up to1740 rpm when the ECM (Z132) will initiate “over runfuel cut–off”.

Heated Oxygen Sensors (X139, X160, X289, X290)

The heated oxygen sensor consists of a titaniummetal sensor surrounded by a gas–permeableceramic coating. Oxygen in the exhaust gas diffusesthrough the ceramic coating on the sensor andreacts with the titanium wire, altering the resistanceof that wire. From this change in resistance, theECM (Z132) can calculate the percentage of oxygenin the exhaust gas and adjust the injected fuelquantity that as to achieve the correct air/fuel ratio.This reduces the emissions of Carbon Monoxide(CO), Hydrocarbons (HC) and oxides of Nitrogen(NOX) to acceptable levels.

Presently, two heated oxygen sensors are used, onein each exhaust down pipe just before the catalyst.

In the event of sensor failure, the system will defaultto ”open loop”. Operation and fuelling will becalculated using signals from the remaining ECMinputs. The fault is indicated by illumination of themalfunction indicator lamp (MIL). ECM diagnosticsalso uses heated oxygen sensors to detect catalystdamage, misfire and fuel system faults.

North American vehicles have two extra heatedoxygen sensors mounted one after each catalyst.These are used to determine whether the catalystsare operating efficiently.

Idle Air Control Valve (M112)

The Idle Air Control Valve (M112) controls the idlespeed of the engine by moving the plunger a setdistance, known as a step. Fully open is zero stepsand fully closed is 180 steps. The motor moves eachstep by sequentially changing the polarity to each ofthe two coils.

SEQUENTIAL MULTIPORT FUEL INJECTION (SFI–V8) A1

CIRCUIT OPERATION 3

Ignition Coils (Z261)

The ignition system on the petrol engine consists ofa “DIS” format, a Direct Ignition System, comprisingof four double ended coils operating on the “wastedspark” technique. The circuit to each coil iscompleted via switching within the ECM (Z132),allowing the coil to charge up and then fire. Itproduces sparks in two cylinders simultaneously, onecylinder on the compression stroke and one on theexhaust stroke. Due to relatively easy ionisation ofthe fuel/air mixture in the cylinder undercompression, the coil will dissipate more energy inthat cylinder than the other, so very little energy iswasted in the system.

Failure of a coil will result in lack of sparks in twocylinders (coil 1 feeds cylinders 1/6, coil 2 feedscylinders 5/8, coil 3 feeds cylinders 4/7 and coil 4feeds cylinders 2/3). This results in a misfire.

Injector/Injectors

The fuel injection system used is a “sequentialmulti–point” system (SFI) i.e. one injector for eachcylinder (compared to “single point” injection orthrottle body injection which uses one injector only).A fuel injector consists of a small solenoid which isactivated by the ECM (Z132), allowing fuel to passinto the combustion chamber. Due to the fuelpressure in the rail and the shape of the injectororifice, the fuel squirts into the cylinder in a finespray to aid combustion.

Relays

The engine management system uses four relays:

– Starter motor, ECM (Z132) power supply (mainrelay), ignition and fuel pump, all located within thefusebox.

Main Relay

This relay supplies the power feed to the ECM(Z132) with a tap off to feed the fuel injectors and airflow meter. This relay is controlled by the ECM(Z132) itself, so that the ECM (Z132) remainspowered up after the ignition is removed and theECM (Z132) can record all temperature readings andmotorise the Idle Air Control Valve (M112) to the fullyopen position. This is known as the “ECM (Z132)power down routine”. Failure of this relay will causethe ECM (Z132) to not be switched on, resulting inabsence of fuel and spark and therefore a failedstart.

Ignition Relay

This relay is ignition key controlled and supplies afeed to the coils, evaporative emission canisterpurge valve and heated oxygen sensor. When theignition key is turned off, supply to the coils is cutimmediately.

Starter Motor Relay

This relay is also ignition key controlled and isactivated with the key in the ignition III position only.Releasing the key after cranking cuts supply to therelay and switches off the starter motor.

Fuel Pump Relay

This relay is fed from the ignition relay and controlledby the ECM (Z132). It is pulled in on ignition IIposition to prime the fuel system. If the key remainsin the ignition II position, then the relay falls out aftera few seconds, precisely when determined by theECM (Z132).

Engine Control Module (ECM) (Z132)

If the ECM (Z132) itself is not working, the entireengine management system will cease to operate:no fuel, sparks, tacho reading, etc.

DIESEL A6

CIRCUIT OPERATION 1

CIRCUIT OPERATION

Sensors

Engine Speed Sensor (X255)

The engine speed signal is crucial to the system, asthe information from the sensor is used in virtually allof the strategies within the ‘DDE’ (Digital DieselElectronics) and its Engine Control Module (ECM)(Z132). Through this sensor, the ECM (Z132) knowsif the engine is turning, how fast it is turning andapproximately where the engine is in its cycle. Thesensor is of the ‘Hall effect’ type, which sends out apulse to the ECM (Z132) every time a ‘tooth’ issensed on the flywheel (the flywheel has six ‘teeth’).If the sensor fails, then the warning lamp is activatedand the ECM (Z132) enters a ‘limp home’ modewhere the ECM (Z132) looks at the signal from theneedle lift sensor in one of the injectors. The needlelift sensor gives one pulse per injection, i.e. onepulse per twelve engine speed sensor pulses. Theresponse of the ECM (Z132) to changes in engineparameters will, therefore, be considerably slower,and a higher idle speed is initiated to try tocompensate at low engine speeds.

Needle Lift Sensor (X318)

The engine has six diesel fuel injectors, one of whichhas a sensing element at the tip which informs theECM (Z132) exactly when the injector fires (the‘beginning of injection’ signal). The ECM (Z132) usesthis to correct the injection timing and also to backup the engine speed signal in case that sensor fails.If this sensor fails, the warning lamp will switch onand the vehicle will enter ‘limp home’ mode withreduced engine power/performance and lack ofthrottle response (as there is a lack of feedback onthe injection timing).

Engine Coolant Temperature Sensor (X126)

This sensor is a ‘thermistor’ (a temperaturedependent resistor) where the voltage output variesin proportion to coolant temperature. The ECM(Z132) uses this information in many strategies, i.e.to correct the injected fuel quantity and timing(especially during cold starts), length of glow plugtiming, etc. The sensor is located in the top of theengine block. In case of a failure, the warning lampis not activated and the ECM (Z132) selects asubstitute value of 50C for glow plug and ignitiontiming and uses the fuel temperature to correct thefuel quantity, glow plug timing will not be correct,possibly resulting in long crank times in cold weather

as well as slight fuelling effects. These symptomsmay not be noticeable.

Air Temperature Sensor (X311)

This sensor is another thermistor, located in the inletmanifold, just after the intercooler, and measures theactual temperature of the turbo booster air enteringthe engine. To calculate the maximum amount ofinjected fuel allowed, the ECM (Z132) needs to knowthe volume of air flowing into the engine. Normally abulky, heavy and expensive air flow meter isnecessary, but the ECM (Z132) can calculate the airflow from the air temperature and air pressure, soeliminating the need for an air flow meter. If the airtemperature sensor fails, a substitute value of 30Cis used, so by producing an incorrect air flow readingand a reduction in engine power.

Page 40: Electronic Troubleshooting Manual RR-P38 eng

DIESELA6

CIRCUIT OPERATION2

Boost Pressure Sensor

The boost pressure sensor signal is used inconjunction with the air temperature signal tocalculate volume air flow into the engine. The sensoris located on the rear bulkhead, with the pressuretap just after the charge air cooler. If the sensor fails,a substitute value of 490 hPa is used by the ECM(Z132), producing a reduction in power due to a fuelquantity limiting to 21mg/stroke.

Throttle Position Sensor (X171)

The DDE system is a ‘Drive by Wire’ system i.e. thethrottle pedal does not directly control a throttle discor the amount of fuel injected into the engine, butaccelerator movements or ‘drivers request’ aresensed and the information is passed to the ECM(Z132). The ECM (Z132) calculates the maximumallowable fuel quantity from the air flow into theengine, engine speed, temperature, etc. It alsoincludes information from strategies such as smokelimitation, active surge damping, automatic gearchange, fuel reduction, etc. to calculate the finalfigure. When driving, if the ‘drivers request’ signal issmaller than the maximum allowable quantity, thenthe requested quantity is injected. However, if therequested quantity is greater than the maximumallowable, then the latter quantity is injected ratherthan the driver’s demand. Therefore the ThrottlePosition Sensor (X171) is very important to thesystem. It is located within the cab, close to thepedal assembly itself. The unit consists of apotentiometer and has three outputs:

1. Throttle Position – pin 37 ECM (Z132)

The sensor outputs the pedal position to the ECM(Z132), which uses the information as describedabove.

2. Idle Position Switch – pin 25 ECM (Z132).

The sensor has a separate idle position switch whichinforms the ECM (Z132) of the pedal status in theform of a simple on/off signal. This information isused by the ECM (Z132) to implement idle speedcontrol’ and other strategies i.e. overrun fuelshut–off’.

3. Kick Down Switch.

This switch is currently not used.

Fuel Temperature Sensor

A thermistor is also located inside the injectionpump. The fuel temperature sensor signal is used toadjust the quantity of injected fuel, especially duringtemperature extremes. The signal is also used toback up the Engine Coolant Temperature Sensor(X126). If this sensor fails, the ECM (Z132) uses a

substitute value of 60C and only slight effects onfuelling may possibly be noted.

Fuel Quantity Feedback Sensor

Located within the injection pump, this sensor sendsthe ECM (Z132) information regarding the actualquantity of fuel injected. Failure of the sensor orcorrupted signals will illuminate the warning lampand cause the engine to stall or not start. A secondcheck, a plausibility check against the needle liftsensor, also takes place.

Page 41: Electronic Troubleshooting Manual RR-P38 eng

DIESEL A6

CIRCUIT OPERATION 3

Fuel Quantity Actuator

Once again located within the injection pump, this isa moving magnet actuator, failure of which will causethe engine to stall or not start as the ECM (Z132) willactivate the Fuel Shut–Off Solenoid (K111).

Injection Timing (Solenoid Valve Injection TimingDevice (K229))

This is another actuator within the injection pump.The ECM (Z132) receives a signal from the needlelift sensor and attempts to correct the injection timingaccordingly. If a change does not occur, then theECM (Z132) assumes a fault exists, activates thewarning lamp and reduces the quantity of injectedfuel.

Fuel Shut–Off Solenoid (K111)

The Fuel Shut–Off Solenoid (K111) shuts the enginedown if the ECM (Z132) detects a major fault.Failure of the valve itself does not activate thewarning lamp, although if a short circuit occurs, theengine will shut down.

Cruise Control

Due to the DDE system being drive by wire’, acruise control feature is supplied in the ECM (Z132)itself. Activation is via the steering wheel switches toa converter box and on a single line to the ECM(Z132). Failure of the signal results in cruise controlnot working.

Brake Switches

The ECM (Z132) has two brake inputs, each ofopposite polarity. Comparison of the polarity statesprovides the ECM (Z132) with a brake sense (i.e. ifswitch 1 high and switch 2 low going to switch 1 lowand switch 2 high) and so cancels cruise control. Ifboth switches are the same polarity, the ECM (Z132)senses a fault and does not allow cruise control.

Vehicle Speed Signal

The ECM (Z132) takes this signal from theAnti–Lock Brake System ECU (Z108) and uses theinformation for cruise control and active surgedamping’. Failure of the signal results in cruisedisallowed and temporary lack of surge damping (i.e.hard acceleration will cause the vehicle to surgeslightly). After 10 sec. a substitute value of 150 km/h

is used. Surging will reduce so as to be hardlynoticeable.

Theft Alarm

The ECM (Z132) has a simple on/off input regardingthe theft alarm. The ECM (Z132) will not allow theengine to start once activated and will kill the engineif activated up to 300 RPM (programmable). Over300 RPM, the engine is unaffected.

Relays

The DDE engine management system on the dieselvehicles uses four relays:

ECM (Z132) power supply (main relay), glow plugrelay, starter motor relay and fuel pump relay. Twoare located in the fuse box and two in the ECM(Z132) box behind the battery.

Page 42: Electronic Troubleshooting Manual RR-P38 eng

DIESELA6

CIRCUIT OPERATION4

Main Relay

Located in the ECM (Z132) box, this relay suppliesthe power feed to the ECM (Z132). It is controlled viathe Ignition Switch (X274) in position II.

Glow Plug Relay (Z135)

The Glow Plug Relay (Z135) takes a feed directlyfrom the battery and, on initialisation via the ECM(Z132), supplies current to each of the six glow plugs(one per cylinder) to aid cold starting. The glow timeis controlled via the ECM (Z132) which also monitorsthe relay and illuminates the glow plug indicator lampfor the duration of the glow time. This relay isrelatively large and is located with the main relaynext to the ECM (Z132).

Starter Motor Relay

This relay is also ignition key controlled, activatedwith the key in the ignition III position only. Releasingthe key after cranking cuts supply to the relay andswitches off the starter motor.

Fuel Pump Relay

The fuel pump relay is pulled in when the startermotor is activated, the earth path provided by thealternator output. When the engine is running, thestarter motor is deactivated, supplying an earth pathwhile the generator supplies a feed i.e. a polarityreversal.

ECM (Z132)

If the ECM (Z132) itself is not working, the entireengine management system will cease to operate,i.e. no fuel, tacho reading, etc.

CIRCUIT OPERATION 1

CIRCUIT OPERATION

Starting System

When the Ignition Switch (X274) is switched toposition III, the BeCM (Z238) grounds the startersolenoid relay inside the Engine Compartment FuseBox (P125) which then energizes, applying batteryvoltage to the Starter Solenoid (K136) and Starter(M134).

Charging System

When the Ignition Switch (X274) is in position II, theBeCM (Z238) turns the charge warning light on viathe datalink connection to the Instrument Pack(Z142)

When the Generator (Z106) starts to produce power,the BeCM (Z238) gets an input signal on Pin 15 andturns off the charge warning light.

For the Diesel engine this signal is also used as aninput signal for the fuel pump relay inside the EngineCompartment Fusebox (P125) to make sure that theFuel Pump (M109) is only supplied with power whenthe engine is running.

If the Generator (Z106) fails to produce power, thecharge warning light remains illuminated.

CRUISE CONTROL B5

CIRCUIT OPERATION 1

CIRCUIT OPERATION

Petrol Engine

For vehicles equipped with a manual transmission,cruise control can only be activated when the CruiseControl Switch (X115) is depressed, the transfergear box is in Hi range, and the clutch pedal is notdepressed. Also, the BeCM (Z238) will deactivatecruise control if the engine rpm rises above 5000 ±10%, due to the possibility of selecting gearsmanually without the use of the clutch.

For vehicles equipped with an automatictransmission, cruise control can only be activatedwhen the Cruise Control Switch (X115) is depressed,the transfer gear box is in Hi range, and thetransmission is in one of the forward gears.

With the Cruise Control Switch (X115) on, a groundsignal is applied to C255/Pin 14 of the BeCM(Z238).The BeCM (Z238) then suplies signal voltagevia its Pin 18 to the Converter/Inverter (Z249), to Pin10 of the Cruise Control ECU (Z121) and to the“Operation” bulb of the Cruise Control Switch (X115).The transfer gearbox Hi range status from theTransfer Gear Box ECU (Z256) is applied toC626/Pin 3 of the BeCM (Z238). The X, Y, and Zswitch status (PRND321 position information) fromthe gearbox position switch is applied to C626/Pins8, 9, and 18 of the BeCM (Z238). The clutch pedalposition input is applied to C255/Pin 4 and theengine speed input C112/Pin 9 of the BeCM (Z238).When the transfer gearbox is in Hi range, a forwardgear is selected and the Cruise Control Switch(X115) is on, theBeCM (Z238) suplies voltage viaC258/Pin 1 and the Brake Switch Vent Valve (X112)to the Cruise Control ECU (Z121) Pin 9, which then“knows” that cruise control can be operated.

When cruise control is activated and a cruise speedis set, the Cruise Control ECU (Z121) appliesvoltage through the OU wire and ground through theOR wire to operate the Cruise Control VacuumPump (M103) motor. The Cruise Control ECU (Z121)applies ground through the OK wire to close thenormally open solenoid valve in the pump. The pumpapplies vacuum to the actuator.

SET/ACCEL

To set a cruise speed, the Cruise Control Switch(X115) must be on and vehicle speed must exceed28 mph (45 km/h). When the SET/ACCEL Switch isdepressed under these conditions, theConverter/Inverter (Z249) is supplied with a ground

signal. This signal is “converted” to a voltage signaland is transmitted via the SY wire to the CruiseControl ECU (Z121) terminal 3, causing the vacuumpump to operate. When the SET/ACCEL Switch isreleased, the signal is removed from terminal 3,signalling the ECU to set the speed.

RES/DECEL

When the RES/DECEL Switch is depressed, a signalis applied via the RY wire to terminal 4 of the CruiseControl ECU (Z121). This tells the ECU (Z121) todisengage the system and the vehicle slows down.When the switch is depressed a second time, thesignal is again applied to the ECU (Z121) and thevehicle returns to the previously set speed.

Speed Input

Terminal 11 of the Cruise Control ECU (Z121)receives the Vehicle Speed output signal from theBeCM (Z238) through the Y or YR wire. The BeCM(Z238) receives the vehicle speed signal from theAnti–lock Brake System ECU (Z108). The signal is apulsing voltage and its frequency changes withvehicle speed.

Page 64: Electronic Troubleshooting Manual RR-P38 eng

CRUISE CONTROLB5

CIRCUIT OPERATION2

System Disable

The cruise control system can be disabled in one offour ways:

8. The Cruise Control Switch (X115) is put in the 0position, removing the BeCM (Z238) power fromthe Cruise Control ECU (Z121) and vacuumpump, and erasing the set speed memory.

9. The RES/DECEL Switch is depressed, signallingthe Cruise Control ECU (Z121) via the Inverter/Converter (Z249) to disengage the system.

10. The brake pedal is depressed and a vacuum val-ve in the Switch Vent Valve opens (X112). Thisvents vacuum to the actuator valve and releasesthe throttle.

11. The Voltage applied to the Cruise Control ECU(Z121) terminal 9 is interrupted, causing theCruise Control ECU (Z121) to turn off the va-cuum pump and de–energize the vacuum sole-noid valve. This voltage path is interrupted when:

The brake pedal is depressed. With the brakepedal depressed, the Brake Switch Vent Valve(X112) moves to position 1 and the circuit is in-terrupted.

The transfer gear box is not in Hi range.

The vehicle speed does not exceed 28 mph (45km/h).

The vehicle is not in a forward gear (P, R, or N)(Automatic Transmission).

The clutch pedal is depressed (Manual Trans-mission).

The engine rpm rises above 5000 ± 10% (Ma-nual Transmission).

The BeCM (Z238), which monitors these signals, willthen remove power from C255/Pin 18.

Diesel Engine

For vehicles equipped with a manual transmission,cruise control can only be activated when the CruiseControl Switch (X115) is depressed and the clutchpedal is not depressed. The Diesel Engine ControlModule (Z132) will not allow the engine to overspeedif a cruise control speed is requested that is beyondthe capability of the engines speed range.

For vehicles equipped with an automatictransmission, cruise control can only be activatedwhen the Cruise Control Switch (X115) is depressed,the transfer gear box is in Hi range, and thetransmission is in one of the forward gears.

With the Cruise Control Switch (X115) on, a groundsignal is applied to C255/Pin 14 of the BeCM (Z238).The X, Y, and Z switch status (PRND321 positioninformation) from the gearbox position switch isapplied to C626/Pins 8, 9, and 18 of the BeCM(Z238). The clutch pedal position input is applied toC255/Pin 4 and the engine speed input is applied toC112/Pin 9 of the BeCM (Z238). The BeCM (Z238)then supplies voltage, via its Pin 18 to theInverter/Converter (Z249) and to the “Operation”bulb of the Cruise Control Switch (X115).

The Cruise Control Converter/Inverter Module(Z249) supplies the Engine Control Module (Z132)via its pin 4 with a voltage signal to “switch on” thecruise circuit. For the Diesel Engine, the EngineControl Module (Z132) controls the cruise circuit asthe Cruise Control ECU (Z121) does for the PetrolEngine. The Engine Control Module (Z132) is alsoresponsible for the acceleration/deceleration of thevehicle.

Page 65: Electronic Troubleshooting Manual RR-P38 eng

CRUISE CONTROL B5

CIRCUIT OPERATION 3

SET/ACCEL

To set a cruise speed, the Cruise Control Switch(X115) must be on and vehicle speed must exceed28 mph (45 km/h). When the SET/ACCEL Switch isdepressed under these conditions, theInverter/Converter (Z249) is suppplied with a groundsignal. This signal is transmitted via the OY wire tothe Engine Control Module (ECM) (Z132) causingthe vehicle to accelerate. When the SET/ACCELSwitch is released, the signal is removed signallingthe Engine Control Module (ECM) (Z132) to set thespeed.

RES

When the RES Switch is depressed, a signal isapplied to the ECM (Z132) and the vehicle will returnto the previously set speed.

Speed Input

The BeCM (Z238) receives the vehicle speed signalfrom the Anti–lock Brake System ECU (Z108). TheBeCM (Z238) then provides the vehicle speed signalto the Engine Control Module (ECM) (Z132). Thissignal is a pulsing voltage and its frequency changeswith the vehicle speed.

System Disable

The cruise control system can be disabled in twoways:

1. The Cruise Control Switch (X115) is put in the 0position, causing the BeCM (Z238) to removepower from the Engine Control Module (ECM)(Z132) and erasing the set speed memory.

2. The Voltage applied via the Inverter/Converter(Z249) to the Engine Control Module (ECM)(Z132) terminal 20 is interrupted, causing theEngine Control Module (ECM) (Z132) to disenga-ge the system. This voltage path is interruptedwhen :

The brake pedal is depressed. The Engine Con-trol Module (ECM) (Z132) has two Stop LampSwitch (X168) inputs, each of opposite polarity.The ECM (Z132) compares the polarity states todetermine when the brake pedal has been de-pressed.

The vehicle speed does not exceed 28mph (45km/h).

The vehicle is not in a forward gear (P, R, or N)(Automatic Transmission).

The clutch pedal is depressed (Manual Trans-mission).

The BeCM (Z238), which monitors these signals, willthen remove power from C255/Pin 18.

TROUBLESHOOTING HINTS

8. If the interior lights operate but the cruise controlswitch light does not illuminate, check the bulb, Bwire and RW wire. If the cruise control systemoperates but the cruise control switch light doesnot illuminate, check bulb and OW wire.

9. Inspect vacuum hoses for kinks and restrictions.

10. Inspect actuator linkage for restrictions and ad-justment.

11. Check the following two input signals to theBeCM (Z238): Signal from Clutch Pedal PositionSwitch (X200) for vehicles equipped with a ma-nual transmission, or the X, Y, and Z switch sig-nals from the Gearbox Position Switch (X294) forvehicles equipped with an automatic transmis-sion.

12. For vehicles equipped with a Petrol Engine,check the following input signal to the BeCM(Z238): Transfer box in Hi range signal fromTransfer Gear Box ECU (Z256).

13. For vehicles equipped with a Diesel engine,check the Stop Lamp Switch (X168) inputs to theEngine Control Module (ECM) (Z132).

14. Note: For vehicles equipped with a manual trans-mission, cruise control can only be activatedwhen the Cruise Control Switch (X115) is de-pressed, the transfer gear box is in Hi range (Pe-trol only), and the clutch pedal is not depressed.Also, the BeCM (Z238) will deactivate cruisecontrol if the engine rpm rises above 5000 +/– 10percent, due to the possibility of selecting ma-nual without the use of the clutch (Petrol only).For vehicles equipped with an automatic trans-mission, cruise control can only be activatedwhen the Cruise Control Switch (X115) is de-pressed, the transfer gear box is in Hi range (Pe-trol only), and the transmission is in one of theforward gears. The Transfer Gear Box ECU(Z256) provides the BeCM (Z238) with transfergear box Hi range status. The Transfer Gear BoxPosition Switch (X294) provides the BeCM(Z238) with X, Y, Z switch status (PRND321 po-sition information).

SYSTEM DIAGNOSIS

1. If the cruise control system does not operate cor-rectly and the vehicle is equipped with a PetrolEngine, do Test A.

2. If the cruise control system does not operate cor-rectly and the vehicle is equipped with a DieselEngine, do Test E.

TRANSFER GEARBOX B6

CIRCUIT OPERATION 1

CIRCUIT OPERATION

Interface to transfer motor inside Transfer Box(X313)

The Transmission Gearbox Control Unit (Z256) hasa seven wire interface to the Transfer Motor insidethe Transfer Box (X313), consisting of the four motorposition switches, the ground for the switches andthe drives to move the motor one way or the other.

Motor Position Switches– pins 17, 32, 33, 7

The Transmission Gearbox Control Unit (Z256)reads the position of the motor in the form of abinary Gray Code.

So the Transmission Gearbox Control Unit (Z256)can find out in which gear the Transfer Box (X313) isin and where the motor should move to, to engagethe desired range. If the Transfer Box (X313) movesoutside the normal modes (e.g. Left of High) then theTransmission Gearbox Control Unit (Z256) can movethe motor back to the correct position.

Motor Position Switch ground– pin 19

The switches on the transfer box motor arereferenced to pin 19, i.e. if there is a problem withthe harness to pin 19 then the TransmissionGearbox Control Unit (Z256) will not be able toassess where the transfer motor is and so will notmove the motor.

Motor drive Clockwise (pins 25, 26) and CounterClockwise (pins 1, 2)

The Transmission Gearbox Control Unit (Z256)receives signals from the motor position switches,the drivers request, the vehicle speed and thetransmission neutral signal and, when theparameters are correct, powers the motor from onemode to another via the motor drives. This is actuallya single wire interface for each direction which issplit down to two wires at the Transmission GearboxControl Unit (Z256) to help pass the current thoughtwo pins rather than one. If there is a problem witheither the motor drives or the harness, then themotor will not move and a range change will not bepossible.

Vehicle Speed Sensor– pins 13, 30

The Transmission Gearbox Control Unit (Z256)senses how fast the vehicle is travelling, comparesthis speed to the value stored in the memory anddecides if a range change is allowed. Presently theshift speeds are set at 5 mph High to Low and Lowto High on vehicles with an automatic transmission

and 15 mph Low to High on vehicles with a manualtransmission.

Interface to BeCM (Z238)

High, Low and Neutral Status Lamps–pins 35, 14, 36

The Transmission Gearbox Control Unit (Z256)informs the BeCM (Z238), which informs theInstrument Pack (Z142), about the range the vehicleis in via three status lamps.

When a range change is requested, the desiredrange will flash up on the display (i.e. “HIGH”) andcontinue flashing until the range change is achieved.When complete, the range message will switch toconstant and be displayed for a few seconds.

If a range change is requested and not all of theconditions are satisfied then the desired rangemessage will flash and continue flashing until all ofthe parameters are satisfied or the request isremoved.

If the transfer box neutral is selected then, after afive second safety delay, the Transfer Box (X313)moves to neutral and the display shows “NEUTRAL”.

The High and Low status lamp signals also passinformation to the H–Gate and the Auto Gear BoxControl Unit (Z255).

Interface to Engine Control Module (ECM) (Z132)

On North American Specification (NAS) vehicles, theinability of the Transfer Gear Box ECU (Z256) tomove into the High range is flagged over the faultoutput line. A fault will also be flagged in the event ofa speed sensor failure or incorrect transfer motorposition information. The Malfunction Indicator Lamp(MIL) will illuminate if a fault is recorded on twosuccessive journeys.

Page 87: Electronic Troubleshooting Manual RR-P38 eng

TRANSFER GEARBOXB6

CIRCUIT OPERATION2

Neutral Switch (X308) or Clutch Switch– pin 34

A shift between ranges is possible when thetransmission is in neutral. The TransmissionGearbox Control Unit (Z256) senses this via aPark/Neutral Switch (X308) on automatictransmission vehicles and via either a clutch switchor a lever neutral switch on manual transmissionvehicles. This signal is passed via the BeCM (Z238).

Interface to “H–Gate”– pin 35, 15 (automatictransmission only)

The H–Gate gets the range information via a Highand Low status signal from the output of theTransmission Gearbox Control Unit (Z256);e.g. when the vehicle is in High then the High side ofthe “H” is illuminated. When a range change to Lowis requested, the Low side of the “H” starts to flashwhilst the High side stays constant. When Low rangeis obtained then the flashing light on the Low sidechanges to constant and the High side light goes off.

If a range change is requested and not all of theconditions are satisfied, then the current range willstay illuminated and the desired range will flash andcontinue flashing until all of the parameters aresatisfied or the request is removed.

If the gear lever is placed in the neutral position forthe gearbox and the transfer box then, after a fivesecond safety delay, the transfer box moves toneutral and the lights on both side of the “H” areextinguished.

Interface to Auto Gear Box Control Unit (Z255)– pin 35

The High/Low signal to the Auto Gear Box ControlUnit (Z255) comes from the High range status lamp.If the Auto Gear Box Control Unit (Z255) does notreceive the range information, then an incorrect gearchange mode could be selected, i.e. Manual ratherthan Sport in High range and vice versa in Lowrange. Also, the shift strategy is different betweenthe Economy modes of High and Low and so poorshift quality could result.

Automatic Selector Park Interlock

When the gear selector lever is in the park position,the shift interlock solenoid is deenergized andprevents the selector from being moved to anothergear. To free the selector, the Ignition Switch (X134)must be in position II and the brake pedal must bedepressed.

Current is then supplied to the solenoid through thePR wire via fuse 13. The solenoid is grounded usingthe B wire to the console ground E621.

The solenoid is now energised, freeing the selector.The solenoid is energised continuously whilst theselector lever is in any position other than park andthe Ignition Switch (X134) is in position II.

AUTOMATIC GEARBOX B7

CIRCUIT OPERATION 1

CIRCUIT OPERATION

Economy, Sport and Manual Modes

The Auto Gear Box Control Unit (Z255) has variousdifferent driving modes available, with Economybeing selected automatically on start up. When thevehicle is in High range, Sport mode can beselected. This will make the gear change much moresensitive to throttle movement, thereby shifting downearlier and holding onto lower gears longer than theEconomy mode equivalent. If the vehicle is in Lowrange, then Manual mode can be selected. This willmake the gear box change into the selected gear asquickly as possible and hold on to that gear at allspeeds, i.e. if “3” is selected, then the gear box willnot shift down to “2” or “1” as the vehicle slowsdown. It will only change gear to prevent the vehiclefrom stalling.

Interface to Petrol Engine Control Module (ECM)(Z132)

The Auto Gear Box Control Unit (Z255) takes theengine torque, engine speed and throttle anglesignals from the ECM, calculates which gear isrequired, outputs to the solenoid valves and sends atorque reduction signal back to the ECM, therebyretarding the ignition point on each of the cylindersand so giving a reduction in engine power duringgear changes that result in a smooth change.

The engine torque is received by the Auto Gear BoxControl Unit (Z255) on its pin 21, the engine speedon pin 3 and the throttle angle on pin 47. The torquereduction signal is sent to the ECM from the AutoGear Box Control Unit (Z255) via its pin 32.

Interface to Diesel Engine Control Module (ECM)(Z132)

The functionality of the interface is similar to thepetrol interface, except for the format of the signal.

Interface to Auto Gear Box Control Unit (Z255)

Gear position Switch–pins 14, 33, 50

The gear position switch is mounted on the side ofthe gearbox and contains five internal switches,although only 3 are connected to the Auto Gear BoxControl Unit (Z255)via pins 50, 14, and 33. Byanalysing the status of these 3 switches, the AutoGear Box Control Unit (Z255) calculates which gearthe vehicle is in.

If a fault occurs with the switch, then the Auto GearBox Control Unit (Z255) may try to put the gearboxinto a different gear than the driver’s request.

Solenoid Valves–pins 5, 6, 19, 24, 42

The Auto Gear Box Control Unit (Z255) has controlover 4 solenoid valves: MV1, MV2, torque converterlock up and pressure regulator. These are allsupplied via pin 19, which is activated via a relay inthe Auto Gear Box Control Unit (Z255) itself.

MV1 – pin 5, MV2 – pin 24:

When the driver selects “D”rive, then the Auto GearBox Control Unit (Z255) controls the gear selectionby the use of the two solenoid valves. If a faultoccurs with one or both of the valves, then adifferent gear than the one selected will result.

If the Auto Gear Box Control Unit (Z255) defaults thegearbox, then the common supply to all the solenoidvalves is removed and the gearbox mechanicallyshifts either to third gear, if the vehicle is stationary,or fourth, if moving.

Page 95: Electronic Troubleshooting Manual RR-P38 eng

AUTOMATIC GEARBOXB7

CIRCUIT OPERATION2

MV2 is also used to prevent the driver from selectingreverse when the vehicle is moving forward at morethan 8 km/h and from disengaging reverse at reversespeeds greater than 6 km/h. This is known as“Reverse Safety” and will not be available if MV2 isnon–operational and/or the gearbox has defaulted.

Torque Converter Lock–Up Solenoid – pin 42:

The torque converter slips to allow smooth operationof the gearbox. Lock–Up occurs when the vehiclereaches a speed of 45MPH or above in either thirdor fourth gears.

Pressure Regulator Solenoid – pin 6:

The gear shift quality is controlled by modulating thepressure regulator, which is controlled by the AutoGear Box Control Unit (Z255). The solenoid isenergised closed, such that if a failure occurs, thenthe regulator allows default gear change.

Output Shaft Speed Sensor –pins 2, 38, 20

The automatic gearbox system incorporates anoutput shaft speed sensor which is input to the AutoGear Box Control Unit (Z255) on pins 2 and 38 witha screen over the cable attached to pin 20. It isimportant that this signal is screened correctly.

MES 1 and 2–pins 16, 31

The two Manual/Economy/Sport (MES) lines indicateto the BeCM (Z238) which mode has been selectedor if a fault within the transmission has occured.

Interface to Transmission Gearbox Control Unit(Z256)

–High/Low Range Signal–pin 46

The High/Low signal is used by the Auto Gear BoxControl Unit (Z255) to select the correct mode onapplication of the “MES” switch. Also, the gear shiftpoints and strategies are very different in thedifferent ranges.

Interface to “H–Gate”–pin 29

The “H”–Gate sensor module (Z254) displaysselected gear information from the Gear BoxPosition Switch (X294), ratio information from theTransmission Gearbox Control Unit (Z256) andmode information from the gear box Auto Gear BoxControl Unit (Z255). The H–Gate receives an ignition2 signal on the W wire. This is fed via fuse 6. It isgrounded to the console ground E621 via the B wire.

Information on the selected gear (PRNDL) isreceived from the Gear Box Position Switch (X294)on wires UB, UP, UG. These three lines also go to

the Auto Gear Box Control Unit (Z255) and theBeCM (Z238).

Information on the gear box mode (sport or manual)is received on the YG wire and the YR wire. Thesetwo lines also go to the BeCM (Z238).

ANTI-LOCK BRAKE SYSTEM D1

CIRCUIT OPERATION 1

CIRCUIT OPERATION

The Anti–Lock Brake System prevents wheel lockupduring braking. This enables the driver to maintainvehicle stability and ‘steerability’ while braking.

The Electronic Traction Control System aids tractionwhen a rear wheel spins or loses traction. Thesystem works by applying the brake to the spinningrear wheel. The braking action allows more torque tobe transferred and applied to the non–spinning rearwheel.

Anti–Lock Brake System ECU (Z108)

The Anti–Lock Brake System ECU (Z108) is acomputer that controls ABS system operation byconsistently monitoring the vehicle’s 4 wheel speedswhen the ignition is in position II. If an impendingwheel lock up is detected during this monitoring, theAnti–Lock Brake ECU (Z108) will apply voltage tothe various inlet and outlet valve solenoids containedin the ABS Booster Unit (Z103). Operation of thesolenoid valves regulates the pressure applied toeach wheel brake calliper and therefore preventswheel lock–up.

Electronic Traction Control (ETC) is an extension tothe Anti–Lock Brake System ECU. In addition tomonitoring the rear wheel speeds for lockup, theAnti–Lock Brake System ECU also monitors wheelspeed for traction control. When rear wheel slip isdetected (one wheel spinning faster than the other),the Anti–Lock System ECU will apply the brake tothe spinning wheel, causing additional torque to beapplied to the non–spinning wheel.

The Anti–Lock Brake System ECU applies the brakeby operating various inlet and outlet solenoid valvesin the ABS Booster.

The ETC warning light will be on for up to 60seconds while the system is active, and themessage TRACTION is displayed. After 60 secondsof ETC operation, the ETC warning light will begin toflash to inform the driver that the system has beenshut down to allow the brakes to cool. Also themessage TRACTION OVERHEAT is displayed.

If the ETC warning light stays on continuously formore than 60 seconds, a fault in the system isindicated. The message TRACTION FAILURE isalso displayed.

The Anti–Lock Brake System ECU (Z108) also hasdiagnostic capabilities that allow it to detect faultsthat may impair the system’s efficiency. If a fault

occurs, the ECU informs the operator of a problemby illuminating the ABS or the ETC warning light.The ECU also illuminates the warning light when theignition is first placed in position II. The ABS warninglight will remain illuminated until the ECU completesa self check of the system. When the ECU sees allwheels reach a speed of 7 km/h (5 mph), the selfcheck is completed and the ABS warning light turnsoff. If a fault is detected during the self check, theABS or the ETC warning light will remain on and afault code will be stored in memory to aid in servicingthe system. When an ABS fault has been detected,the message ABS FAULT may also display.

The fault code can be retrieved using a diagnostictester.

Page 106: Electronic Troubleshooting Manual RR-P38 eng

ANTI-LOCK BRAKE SYSTEMD1

CIRCUIT OPERATION2

ABS Booster Unit (Z103)

The ABS Booster Unit (Z103) contains 2 isolationsolenoid valves and 4 pairs of solenoid controlvalves which are grounded through the harness.When the ETC is fitted, the booster unit alsocontains an additional 2 solenoid valves. The pairs ofsolenoid control valves each include a fluid pressureinlet and outlet valves that control ABS braking toone wheel.

The Anti–Lock Brake System ECU (Z108) operatesthese valves by applying battery voltage to them.The valves are designed to decrease, hold orincrease pressure to retain wheel rotation andoptimum braking.

The 2 isolation valves consist of 2 solenoid valvesthat control fluid inlet and outlet. Their function is todisconnect or isolate the master cylinder from theservo cylinder and to connect the servo cylinder tothe reservoir return during ABS functions.

Wheel Speed Sensors (X137, X140, X158, X161)

A wheel speed sensor is located at each wheel. Thespeed sensors generate an AC voltage signal as atoothed ring rotates past the stationary sensorpickup. The Anti–Lock Brake System ECU (Z108)calculates the wheel speed by measuring thefrequency of the AC voltage signal generated by thesensors.

ABS Hydraulic Pump (M102)

The hydraulic boost for the system is provided by theABS Hydraulic Pump (M102), which is controlled bythe ABS Pump Relay (K102) and the ABS PressureSwitch Unit (Z104).

The Pressure Switch unit incorporates threeelectro– mechanical switches. The first operates thepump, two more illuminate the low pressurecondition and signal that ABS and ETC functionsshould be curtailed. The Hydraulic Pump includes ahydraulic accumulator and non–return valve, as wellas a pressure relief valve to protect the system.

When low pressure occurs in the brake system, aswitch in the pressure switch unit closes to groundthe coil of the pump relay. The pump relay nowenergizes and applies battery voltage from the fuseto the hydraulic pump through the closed relaycontacts. The hydraulic pump runs to increasepressure in the hydraulic accumulator. Whensufficient pressure is developed in the system, thepressure switch opens to de–energize the pumprelay and to turn off the hydraulic pump.

ABS Warning Lamp

The Anti–Lock Brake System ECU (Z108) sendssignals to the BeCM which then controls theillumination of the ABS warning lamp. The BeCMalso controls the display of the system messages.

Solenoid Valve Relay

This is energized by the ABS ECU and sendsvoltage back to the part of the same ECU whichcontrols the solenoid valves in the booster. When theABS ECU detects a fault that requires a completesystem shutdown, the relay is de–energized.

CIRCUIT OPERATION

Engine Coolant Temperature Gauge

The engine coolant temperature gauge sensor hasthe capability to sense from –40C to +130C. Petroland Diesel resistance valves are different.

Both Petrol and Diesel sensors are interfaced to theInstrument Cluster (Z142) via the BeCM (Z238). Theresistance value then being represented by an A/Ddata transfer generating the required angulardeflection on this gauge. ]

Fuel Gauge

When the fuel tank level is low (“E”), the resistancevalue of the gauge sensor is 270Ω for petrol anddiesel engines. As the fuel level increases, theresistance of the sensor decreases. When the fueltank is full, the resistance value of the sensor forpetrol engines is 19Ω and for diesel engines 25.8Ω .When the fuel gauge sensors resistance valueincreases to 175Ω (9 liters/2.25 US gallons, the lowfuel warning light will illuminate to warn of the fuelstatus. Both Petrol and Diesel sensors are interfacedto the Instrument Cluster (Z142) via the BeCM(Z238). The resistance values then beingrepresented by an A/D data transfer generating therequired angular deflection on the gauge.

Speedometer

The signal to activate the gauge is originated at theABS wheel sensors, transmitted to the ABS ECU(Z108) which then puts out a usable signal to theInstrument Cluster (Z142) of 8000 pulses per mile or4972 pulses per kilometer. The signal is alsotransmitted to other ECU’s, such as the EngineControl Module (ECM) (Z132) and the Cruise ControlECU (Z121).

Tachometer

The tachometer will display the engine speed inR.P.M. It will derive the engine speed from theengine speed pulse train transmitted from the EngineControl Module (ECM) (Z132).

The pulse rate for petrol engines will be 4 pulses perengine revolution.

The pulse rate for diesel engines will be 3 pulses perengine revolution.

Audible Warning

Receipt of an audible warning request signal from avehicle parameter/message condition shall cause theBeCM (Z238) to generate the required number ofwarning tones. The actuator sounder unit is locatedat the rear of the Instrument Cluster (Z142).

See message listing for categories/priority and levelsof audible warnings.

RADIO E6

CIRCUIT OPERATION 1

CIRCUIT OPERATION

Battery Voltage is provided to the radio at all timesthrough the P wire. In addition to the anti–theftfeature, this input voltage keeps the preset stationmemory alive. Whenever battery power to the unit islost, the anti–theft code must be entered and thepreset stations must be reprogrammed.

When the Radio (Z111) and the igntion are turnedon, the voltage signal through the WK wire to thecontrol head ‘wakes up’ the unit. The Radio (Z111)plays, the LCD display comes on and the controlbuttons illuminate. On some models, when the parklamps or headlamps are turned on, a voltage signalis sent through the RW wire to dim the LCD displayand control buttons for night driving.

Radio (Z111) signals are received via a coaxial cablefrom the side screens and antenna amplifiers. Theamplifiers filter and boost the signal from the sidescreen, using power supplied on WO wires,whenever the Ignition Switch (X274) is in position Ior II.

The CD Changer (Z114) is permanently suppliedwith power through the P wire via the radio and aDIN cable.

For the new Range Rover, three levels offactory–fitted in–car entertainment are available.

The mid/low line radio has the following features:Electronically tuned AM/FM cassette radio (Z111),RH antenna amplifier (Z178) for AM/FM signals and6, 8 or 10 speakers.

The high line (NAS/JAPAN) radio has the followingfeatures: Electronically tuned AM/FM cassette radio(Z111), RH antenna amplifier (Z178) for AM/FMsignals, LH antenna amplifier (Z177) for FM signalsonly, 4 door speaker amplifiers (Z241, Z242, Z245,Z246), a subwoofer amplifier (Z176), a CD changer(Z114) and 10 speakers plus a subwoofer speaker(K146).

Subwoofer

The subwoofer amplifies frequencies between 20and 150 Hz to give an enhanced bass sound.

Subwoofer Amplifier

The Subwoofer (K146) is supplied with power andground from the Subwoofer Amplifier (Z176) via twoseparate channels which consist of 4 BW/B wires.The subwoofer amplifier (Z176) is permanently

supplied with power on the P wire, but it is onlyswitched on when the radio supplies a signal on theSB wire.

Speaker Amplifier

The Speaker Amplifiers (Z241, Z242, Z245, Z246)are situated in the 4 doors and are supplied withpermanent power via the P wire. They are switchedon when the radio sends a signal on the SB wire.The speaker amplifiers (Z241, Z242, Z245, Z246)have one channel for the bass speakers (K202,K203, K209, K220) and a second for the midrangespeakers (K200, K201, K2111, K212) and tweeterspeakers (K197, K198) (front doors only). Thetweeter incorporates a capacitor to filter the signals.

Page 134: Electronic Troubleshooting Manual RR-P38 eng

RADIOE6

CIRCUIT OPERATION2

Side Screen Antenna

The antenna is printed into the rear side screen. ForNAS and Japan, the element is fitted in both rearside screens. This is referred to as a diversityantenna system. Other markets have a singleelement in the right hand screen only. Diversityreception means that as vehicle movement results inloss of signal due to reflections from buildings(known as multipath distortion), the radio will switchto the antenna receiving the strongest signal. Thisresults in less interference and better stereoperformance.

Antenna Amplifier

Antenna amplifiers are in the LH and RH side of theluggage compartment behind trim panel.The FM andAM amplifier would be located on the right handside, and the FM only amplifier is located on the lefthand side.

Speakers

Trim level 1/2 – The low/midline radio is equippedwith 6, 8 or 10 speakers fitted in the doors. Themidrange speakers (K200, K201, K211, K212) arefiltered by capacitors in the wires (K239, K240,K247, K248) and the tweeter speakers (K197, K198)filter the signals by built–in capacitors.

Trim level 3 – the high line is equipped with 10speakers like the trim level 1/2, but they all receivepower and ground via 4 additional speakeramplifiers. The signals for the tweeter speakers(K197, K198) are filtered by their internal capacitors,similar to the mid/low line tweeters.

TROUBLESHOOTING HINTS16

TROUBLESHOOTING HINTS

3. Check fuses F1, F8, F9, F14 and F15 of BeCM(Z238).

4. Check that Radio (Z111) connectors and coaxialcable are tight and properly connected.

5. For proper Radio (Z111) noise diagnosis, takethe vehicle outside where signals are strong.Close the hood and keep away from metal buil-dings or other sources of Radio interference.

6. If Radio (Z111) noise is excessive when an ac-cessory is on, install a radio noise suppressioncapacitor to the power lead of the accessory.

7. If Radio (Z111) noise is excessive at all times,check antenna wiring, side screen antennas andantenna amplifiers. If OK, check speaker plugs,spark plug wiring and wiring close to the ignitionsystem which could transmit noise to the Radio(Z111) wiring.

8. If only the CD Changer (Z114) does not operate,check DIN cable. If OK, check Radio and CDChanger (Z114).

9. If the Radio (Z111) is inoperative and displayseither CODE (low line) or CODE IN (all others),follow the instructions below.

Security Code Instructions

Low Line (PRC7613)

Obtain the 4 digit security code from the customer’ssecurity card or, if they have lost it, from themanufacturer.

1. Press the preset 1 button once.

2. Using the arrow up and arrrow down buttons,change the – to show the first digit of the code.

3. Press the preset 1 once.

4. Repeat steps 2 and 3 for digits 2, 3 and 4.

5. When the preset 1 button is pressed after thefourth digit, operation should be restored.

If the wrong code is entered, the word WAIT willappear. Do not switch off. Wait until CODE appears,then try again. The time delay will increase eachtime an incorrect code is entered.

All others (PRC7617, PRC7618, AMR2672)

Obtain the four digit security code from thecustomer’s security card or from the manufacturer.

Enter the code using the preset buttons (1 to 6).When the final digit is entered, the radio shouldreturn to full operation.

If the wrong code has been entered, the display willshow the number just entered, instead of thefrequency. This must be cleared by pressing andholding the BAND button for 5 seconds. The displaywill then revert to CODE IN, and the code should beentered.

If the wrong code is entered more than THREEtimes in succession, the code can no longer beentered. Units PRC7617 and PRC7618 will show–––. When this clears, input the correct code. UnitAMR2672 will allow the code to be entered, but willnot respond even if the code is correct. If thishappens, leave the set switched on for at least onehour without touching any controls. After waiting thistime period, try again.

WASH/WIPE F5

CIRCUIT OPERATION 1

CIRCUIT OPERATION

Front Wipers

The front wipers will only operate with auxiliary orignition on, except when auxiliary and ignition areboth turned off, the wipers will continue to operateuntil they reach the park position. If the engine iscranked while the wipers are on, then the wiperoperation will be suspended until cranking isreleased.

Flick Wipe Operation

When the flick wipe switch is operated, the wiper willoperate in the slow wipe mode until the switch isreleased.

Intermittent Operation

When the wiper control stalk is moved to theintermittent position, the wipers will perform one wipeof the screen at slow speed and then wait for Nseconds before doing another wipe etc. The value ofN is determined by the position of the wipe delaypotentiometer. When the potentiometer is in the farleft position the time delay is 2 seconds. Eachmovement of the potentiometer to the right doublesthe time delay, up to a maximum of 32 seconds.

Slow Speed Operation

When the wiper control stalk is moved to the slowposition, the wipers will operate continuously at slowspeed.

Fast Speed Operation

When the wiper control stalk is moved to the fastposition, the wipers will start operating at fast speedimmediately and will continue to do so until fastspeed is switched off.

Front Screen Programmed Wash/Wipe

If the wash/wipe switch is operated, the front screenwash motor will operate for 1.5 seconds or for theduration the switch is held on, whichever is thelonger.

The slow front wipe will be operated for 0.5 secondsafter the switch is closed and will continue to operateuntil three full wipes have been completed after thewash motor has ceased it’s operation.

Rear Wiper

Intermittent Operation

When the rear wiper stalk is moved to the “on”position, then the rear wiper will perform twocomplete wipes and stop in the park position. After

that, its operation will vary depending on theselected mode of the front wipers.

Reverse Gear Wiping

If reverse gear is selected while auxiliary or ignitionis on and a front wiper function is selected, then therear wiper will operate as well.

If reverse gear is selected while the front wipers areoff (or performing a wash/wipe cycle) then the rearwiper will operate in the mode indicated by the rearwiper switch.

Rear Screen Programmed Wash/Wipe

If the rear wash/wipe switch is operated, the rearscreen wash motor will operate for 1.5 seconds orfor as long as the switch is held on, whichever is thelonger. The rear wipe will be operated 0.5 secondsafter the switch closed and will continue to operateuntil three full wipes have been completed after thewasher motor has ceased it’s operation.

Wiper Operation With Speed Dependency On

If the vehicle has speed dependent wipers, the wiperadapts its speed to the vehicle speed.

The speed barrier, where the wipers move betweena faster or slower operation, is 2 mph.

Headlight Wash/Wipe

If the headlight switch is in the on position, the firstand every alternate operation of the front screenwash switch will activate the headlight wash/wipemotor, which will operate for 2 seconds, regardlessof the length of time the switch is pressed.

HEATED FRONT SCREEN F6

CIRCUIT OPERATION 1

CIRCUIT OPERATION

This operates only with the engine running, which isdetermined by the HEVAC panel. In the off state, thesignal is at 12 volts. When the Heated FrontWindscreen is activated, the signal is switched to 0volts. This provides the ground required for relay 5 tobe pulled in, as there is an ignition feed on the otherside of the coil provided by relay 15. This relayenergises one half of the heated screen elements.

Once relay 5 has been energised, a 12 volt signal isprovided to the coil of relay 4. The other side of thecoil is connected directly to ground, therebyenergising the relay and switching on the other halfof the elements.

There is also a feed spliced from the harness whichprovides the petrol Engine Control Module with asignal that tells the unit there will be a large electricalload turned on/off.

HEADLAMPS H1

CIRCUIT OPERATION 1

CIRCUIT OPERATION

Dipped Beam Headlamps

Operation of the headlamp switch will activate theLH and RH dipped beam headlamps, regardless ofthe state of the ignition switch.

Headlamp Delay

The term “headlamp” used throughout this section isassumed to be either dipped beam or main beam, asselected by the main beam changeover switch. Thisswitch will continue to function for the duration of thedelay period.

The headlamps will operate when the headlampswitch is set to the headlamp position, regardless ofthe status of the ignition switch.

If the ignition switch is turned off and the key re-moved whilst the headlamps are on, and the head-lamp switch is subsequently turned off with a dwell ofless than 1 second in the side lamp position, then a25 second headlamp delay will be initiated.

If the ignition switch is turned off and the key re-moved while the headlamps are on and the head-lamp switch is subsequently turned to the side lampposition for greater than 1 second then the head-lamps will be switched off and parking lamps will re-main on until the headlamp switch is turned off, orturned back to the headlamp position.

The headlamp delay may be cancelled immediatelyat any time while it’s active (master lighting switch inthe off position) by the following actions:

Insertion of the ignition key or selection of auxi-liary /ignition (all exterior lamps will be extinguis-hed).

Turning the headlamp switch to the side lampposition. In this case the exterior lamps will im-mediately revert to parking lamps mode.

Turning the headlamp switch to the headlampsposition. In this case the headlamps and normalside lamps (i.e. not parking lamps) will be active.

Main Beam/Side lamp Warning lamps

The main beam warning lamp will be activated when-ever the main beam lamps are on, regardless of thestate of the ignition switch. The side lamp warninglamp will be active whenever the side lamp switch ison and the side lamps are operating in side lampmode, but not when the key is removed and theparking lamp mode is on.

Main Beam Headlamps

The main beam change over switch has a momen-tary action, which will cause the headlamps to switchbetween dipped and main beam on each operation.

Operation of the main beam changeover switch,while the dipped beam headlamps are activated andthe front fog lamps are inactive, will cause thedipped beam lamps to be extinguished and bothmain beam 1 and main beam 2 lamps to be illumi-nated.

Operation of the main beam changeover switch,while both dipped beam and front fog lamps are ac-tive, will cause the dipped beam lamps to be extin-guished and the main beam 1 lamps to be illumi-nated.

Daytime Running lamps

This feature is a requirement for vehicles for the Ca-nadian, Norwegian, Swedish and Finnish markets.

On these vehicles, with the engine running, daytimerunning loads will be active regardless of the state ofany switches.

This feature will in no way effect the operation of anyof the other lighting systems.

CIRCUIT OPERATION

Front Fog lamps

With the ignition switch and side lamp or headlampswitch on, a momentary operation of the front foglamp switch will activate the front fog lamps. A fur-ther momentary operation of the fog lamp switch, orswitching off of the headlamps/side lamps or ignition,will cause the front fog lamps to be extinguished.N.B. The front fog lamps will always be inactivewhen the ignition is turned on.

Rear Fog lamps

With the ignition on, the headlamp switch on or frontfog lamps on, a momentary operation of the rear foglamp switch will activate the rear fog lamps. Opera-tion of the rear fog lamps will also activate a bulbwithin the fog lamp switch. A further momentary op-eration of the fog lamp switch, switching off the headlamps and front fog lamps, or switching off the igni-tion, will cause the rear fog lamps to switch off. N.B.The rear fog lamps will always be inactive when theignition is turned on.

INTERIOR LAMPS J1

CIRCUIT OPERATION 1

CIRCUIT OPERATION

Courtesy lamps

Automatic courtesy lamp facility enabled

With the tailgate or any of the four doors opened theillumination level of the following lamps will fade onover a period of approximately 0.5 seconds:

front courtesy lamp

rear left courtesy lamp

rear right courtesy lamp

load space lamps

front left footwell lamp

front right footwell lamp

ignition ring illumination

rear right footwell lamp

rear left footwell lamp

If any door is left open, the lamps will fade out after atime of approximately 10 minutes. During the 10minute time out, if any other door is opened the timerwill be reset.

If all doors are closed prior to the end of this 10minute period then all specified lamps will fade outafter a delay of 15 seconds.

If the ignition is switched on before the end of the 15second time out period, the specified lamps willbegin to fade out after a delay of 1 second.

If the ignition is then switched off and no dooropened, the 15 second time out of the lamps will notbe resumed.

If an unlock signal is received from the remote key,or if a key unlock is received from either of the frontdoors while all the doors are closed, then thecourtesy lamps will fade to on in 0.5 seconds andbegin a 15 second time out period.

If any of the doors or the tailgate are opened duringthis delay, then the time out period will be restarted.

If all the doors are closed and a lock signal isreceived from the remote key or either of the frontdoor CDL switches while the courtesy lamps are intheir 15 second time out period, then the time delaywill be cancelled and the lamps immediately fadedout.

Automatic courtesy lamp facility disabled

Whenever the main courtesy lamp switch is operatedfor greater than 2 seconds, the automatic courtesylamp feature will switch between the enabled anddisabled mode upon release of the switch. At the

same time an “Int lamps off”/“Int lamps auto”message will be displayed on the instrument pack.This extended switch operation will also extinguishthe courtesy lamps if the button has been depressedfor 2 seconds, causing the system to switch from theautomatic to disabled mode, but otherwise will haveno effect on their state.While the automatic courtesylamp facility is disabled, the courtesy lamps may onlybe switched on and off by momentary activation ofthe main courtesy lamp switch. The change of lampstate will occur on release of the switch.

Panel Dimmer:

Operation of the panel dimmer switch, with the sidelamps on, will alter the level of panel illumination be-tween approximately 6 and 94%. Depressing theswitch momentarily will cause the illumination to in-crease or decrease to the next level. Holding theswitch closed will cause the illumination to ramp to-wards fully on or fully off.

The illumination level selected will be stored in theBeCM’s non–volatile memory whenever the driver’sseat store sequence is completed successfully, pro-vided the side lamp switch is on. If the side lampswitch is not on and a successful memory store se-quence is completed, then the previously stored illu-mination level will remain unchanged.

Puddle lamps

With any door open and the automatic courtesy lampfeature enabled, the puddle lamp within the relevantdoor will be illuminated, either until the door is closedor a time period of approximately 10 minutes haselapsed. If any puddle lamp is on, momentaryoperation of the courtesy lamp master switch willextinguish all puddle lamps on release of the switch.

Further operation of the switch or reopening a door(if automatic courtesy lamps are enabled) will againactivate the puddle lamps for those doors that areopen. If the courtesy lamp switch is held on forlonger than 2 seconds, the automatic operation ofthe puddle lamps from the door open switches willswitch between enabled and disabled.

CIRCUIT OPERATION 1REV: 02/98

CIRCUIT OPERATION

Ignition position 1 (Accessories)

This feed is obtained from the BeCM via fuse 8 andis shared with the Radio, Front cigar lighter, Aerialamplifier and car phone (if fitted). The Ignition 1 isessential to the control panel as it provides power tothe ECU although no functions or display on the LCDare possible.

Ignition position 2

This feed is obtained from the BeCM via fuse 17.

Battery feed

This feed is obtained from the fuse box via fuse 42.

Ground Connection

This feed runs down to a spliced joint, joining themain earth run down to fascia earth point 1.

Dimmer Line

This Pulse Width Modulated signal is provided by theBeCM.

LCD Dimmer line

This line is a input to the HEVAC and the signal is ainverse Pulse Width Modulated signal which isdetermined by the instrument pack.

Compressor Clutch

The clutch line provides a 12 volt power feed to thecompressor clutch via pressure switch 1.

Condenser Fans

The HEVAC panel provides a signal normally at 12volts for “off” condition and 0 volts for the “on”condition, which in the case of petrol vehicles is fedinto the ECM and diesel vehicles directly onto thecoil of relay 18. In line is the Air–Conditioningpressure switch 2, which turns the fans on/off.

When relay 18 is energised, it provides connectionbetween relays 13 and 14 (fan 1 and 2) in series orparallel with each other. This is dependent upon thestate of the air–conditioning pressure switch 1.

For the petrol option, when the signal enters theECM, the ECM will switch the output on/off to thefusebox. The ECM will switch the output onsometimes for engine cooling reasons even thoughthe engine has been turned off.

Aspirator

There are two parts of this sensor, one of which is afan which draws cabin air onto the temperaturesensor. The temperature sensor then sends thesignal back to the HEVAC ECU.

Ambient Sensor

This sensor measures the temperature of theexternal air flow into the vehicle.

For vehicles with VIN’s up to 381430:

The ambient temperature sensor is located behind thedrivers side of the fascia.

For vehicles with VIN’s from 381431:

The ambient temperature sensor is located behind theLH side of the vehicle in front of the condenser. Therevised location improves the response time of thesensor. The new HEVAC software will not update theambient temperature sensor readings unless thevehicle is travelling over approximately 15 mph (25km/h). The HEVAC software will therefore not auto-matically correct temperature readings when a faultyambient temperature sensor is renewed.

Temperature Resistance (Ohms)

30° C (86° F) 8.1 K

40° C (104° F) 5.4 K

Heater Core Sensor

This sensor measures the engine coolanttemperature within the fascia area.

Evaporator Sensor

This sensor is located within the evaporator unit and,by providing feedback to the HEVAC ECU, preventsit from freezing.

Alternator Charge signal

This signal is given to the HEVAC ECU to inform itthat the engine is running. This signal is active low.

Diagnostic K line

This line is used to communicate with the diagnosticequipment (TESTBOOK) and is normally held at 12Vwhen not active.

Road Speed

This signal is fed into the HEVAC ECU.

Solar Sensor

This sensor provides the HEVAC ECU with thepower of the sun’s solar load and allows the systemto compensate accordingly.

Page 222: Electronic Troubleshooting Manual RR-P38 eng

HEATING AND VENTILATION (WITH A/C)K4

CIRCUIT OPERATION2

A/C Request

This signal is active low and sends a request to theECM to switch on the air–conditioning system.

A/C Grant

This signal is active low and sends a signal to theHEVAC ECU to acknowledge the request signal andthat it is ready for the load to be switched on by theHEVAC system.

Pressure switch 1 (Trinary switch)

This switch is in parallel with two components, thecondensor fans and the compressor clutch which areboth normally short circuit. If the pressure is too highor too low, the switch will open and cut the feed tothe clutch to prevent damage to the system. With thethird setting, at a specific pressure the switch isshorted and changes the condenser fan mode fromseries to parallel.

Pressure switch 2 (Single switch)

The switch is normally open circuit. At a specificpressure, the switch is shorted and allows thecondenser fans to turn on.

Left/Right Recirculation motors

These motors control the flaps on the blower motormodules. The flaps should be in one of twopositions, either fully open or fully closed.

Left/Right Blower modules

The blowers have a permanent 12V feed to them.The speed of the motors is determined by the controllines which go to the motors. The motors alsoprovide a voltage feedback to the HEVAC ECU todetermine the actual voltage at the motors but alsoto show if there are any faults.

POWER WINDOWS L1

CIRCUIT OPERATION 1

CIRCUIT OPERATION

The window lift system will provide one touch or inchmode on all windows and will have the anti–trapfunction (when initialised) on close.

Initialised window operation.

Selection of any* aperture switch, in either direction,for less than 0.4 seconds shall initiate the “onetouch” mode of operation. That aperture will bedriven in the direction selected until a trap(obstruction) is detected (close only) or the motorstalls. This mode will be cancelled by the operationof the associated switch in the opposite direction. Ifthe associated aperture switch is operated in theopposite direction then the window will be driven inthat direction according to the requirements for onetouch/inch mode operation.

* Rear window one touch up is a programmablefeature.

Selection of any aperture switch for greater than 0.4seconds will cause that aperture to operate in the“inch mode”. The aperture will move in the selecteddirection until a trap (obstruction) is detected (closeonly), the limit of travel is reached or the switch isreleased.

All windows will operate independently from eachother and may operate in parallel. In case of conflictbetween switches, those in the centre console switchpack will have priority.

The window lift system will only be active under thefollowing conditions:

a) while auxiliary is on, ie, the window system will notbe active during crank. Any one touch operations willbe cancelled when ignition 1 turns off during crank.

b) for the first 45 seconds after auxiliary has beenswitched off, the one touch up and down functionswill not be available during this time period. If, duringthe above 45 second time period, the drivers door isopened, the window system will remain active for afurther 45 seconds from the door opening or until thedoor is closed again, whichever is sooner. If duringeither of the 45 second time periods a door locksignal is received, then the timer will be cancelledand therefore the window lift system will no longer beactive.

The rear windows can be prevented from beingoperated from their local switch by the rear inhibitswitch in the centre console. In the event of a centreconsole serial link failure being detected, the localrear window switches will default to inhibited.

Operation of the driver’s window down switch willcause the drivers window to move in the downdirection until the switch is released (unless in theone touch mode), the up switch is operated, or untila stall condition is detected (i.e. the window is fullyopen).

Operation of the drivers window up switch will causethe window to operate in the close direction until theswitch is released (unless in the one touch mode),the window down switch is operated, a trap conditionis detected, or until the motor stalls (i.e. the windowis fully closed).

Market Deviations:

a) USA/Canada/Germany:

The system will only be active when the auxiliary(ignition 1) is on, or for the time between switchingthe auxiliary feed off and opening either of the frontdoors, but not exceeding 45 seconds.

b) Australia: One touch operation will only beavailable for the drivers window.

SUNROOF L4

CIRCUIT OPERATION 1

CIRCUIT OPERATION

The sunroof can operate in either slide or tilt mode.To change from one mode to the other, the sunroofmust be in the closed position, the switch releasedand then repressed.

The sunroof functions will be active if the ignition isselected or for the first 45 seconds after it has beenswitched off provided that no door lock signal isreceived, in which case the timer will be cancelled.

The sunroof slide function will operate in one of twomodes: one touch, or dead man’s handle. One touchmode is initiated when the sunroof switch is operatedfor less than 400ms, dead man’s handle mode isinitiated when the sunroof switch is operated for400ms or more. Further operation of either sunroofswitch during the one shot mode will cause thesunroof to stop operation.

The sunroof tilt function will operate in deadman’shandle mode only.

There will be trap detection on sunroof close and ontilt close, but not on opening operations.

If a trap is detected whilst the sunroof is closing fromthe slide position, then the sunroof will back off 20cmor until the motor stalls. If a trap is detected whilstthe sunroof is closing from the tilt position then thesunroof will back off to the fully tilt open position.These conditions will also activate a message on theinstrument pack which will be accompanied by threeaudible beeps.

With the sunroof in the closed or partially tilted openposition, operation of the sunroof forward switch willcause the roof to operate in the tilt open direction.This will continue until the switch is released, or untila stall condition is detected.

If the sunroof back switch is operated while thesunroof is in the tilt open position, the roof willoperate in the tilt close direction. This will continueuntil the switch is released, a trap is detected or untilthe sunroof is in the closed position.

If the sunroof back switch is operated with thesunroof in the closed or partially open position, thesunroof will operate in the open direction. Thismovement will continue until the switch is released(unless in the one touch mode), the sunroof forwardswitch is operated, or a stall condition is detected.

With the sunroof in an open position, operation of thesunroof forward switch will cause the sunroof tooperate in the close direction. This will continue untilthe switch is released (unless in the one touchmode), the sunroof back switch is operated, a trap is

detected, or until the sunroof is in the fully closedposition.

The heated rear window will be inhibited for theduration of any sunroof operation.

Market Deviations:

USA/Canada: the system will only be active when the auxiliary or ignition feeds are on, or for the time between switching theignition feed off and opening either ofthe front doors.

Australia: the system will only be active when the ignition switch is in the auxiliary, the ignition or the crank position, or for 45 seconds after the key is removed from the ignition switch.

HEATED SEATS M6

CIRCUIT OPERATION 1

CIRCUIT OPERATION

Driver and passenger seat heaters are PTCregulated. Heated seat activation requests andtiming functions are generated by the Hevac ECUwhile the Ignition Switch (X274) is in position II. TheBeCM (Z238) provides power switching only for thisfunction. In the case of both rear windows and thesunroof being operated at the same time or anuninitialised rear window or sunroof function beingoperated, the seat heaters will be inhibited tomaintain current demand within a safe operatingarea.

The signals are sent from the HEVAC ECU to theBeCM (Z238) and are active low. Therefore the linesare normally held at 12V.

CIRCUIT OPERATION 1

CIRCUIT OPERATION

General

The following combinations of seat and mirroradjustment method will be available:

11. Memory driver’s seat, memory passenger seatand memory mirrors.

12. Memory driver’s seat, electric passenger’s seatand memory mirrors.

13. Mechanically adjusted driver’s and passenger’sseats, electric mirrors.

The memory mirror system will store the horizontaland vertical position of each mirror. Storage andrecall functions will be controlled by the driver’smemory seat control switches, each seat memoryposition having a mirror memory position associatedwith it.

Memory mirror enable and one touch enable willoccur under the same conditions as memory seatenable and one touch enable .

Reverse dip position

Reverse mirror dipping will be enabled when thepresence of a driver’s side seat memory outstation isdetected.

If a driver’s seat memory store sequence is executedwhilst auxiliary is selected and the transmission is inreverse, then the stored mirror position will be theposition that the mirrors will dip to when reverse gearis next selected and that memory number iscurrently recalled. To protect against accidentalsetting, the mirror position will only be stored if it hasbeen altered since reverse was selected and amessage on the instrument pack will inform thedriver that the mirror position has been stored.

The function may be toggled on and off by holdingthe memory store button for at least 2 seconds whilstin reverse gear with auxiliary or ignition selected.

Successful toggling of the function will beaccompanied by the message “Mirror dip on”/“Mirrordip off” as described in the message parametertable.

Successful toggling of the function will result in themirrors moving immediately to the dipped/undippedposition as appropriate.

Storing a new reverse dip position will automaticallytoggle the function on.

Vehicles fitted with automatic transmission will havea 0.5 sec delay following the selection of reversegear prior to the mirror dip position being recalled.

The Electronic Air Suspension (EAS) is designed tomaintain the selected vehicle height under varyingloads. This is achieved by adjusting the quantity ofair within the air springs located next to each wheel.It should be noted that the system is not intended tocontrol the roll or dive of the vehicle whilst corneringor braking. The accuracy of height control achievedis sufficient to ensure that no additional drivercontrolled means of adjusting the headlamp beam isrequired to compensate for different vehicle loadingconditions.

The system can operate in any one of five heights ormodes: Access, Low Profile, Standard Profile, HighProfile and Extended Profile. All heights with theexception of Extended Profile can be selected by thedriver using the ride height switches on the fascia.When Inhibit is selected (indicated by the Inhibitswitch tell–tale lamp being illuminated), automaticheight changes between Standard and Low Profileare disabled; it is recommended that StandardProfile Inhibit mode is selected whenever a trailer isbeing towed.

The ride height of the vehicle is displayed to thedriver by the LEDs in the ride height display adjacentto the ride height switches on the fascia. The LEDfor the current ride height is continuously illuminatedwhenever the engine is running. When a heightchange is taking place, the LED for the new targetheight flashes and the LED for the old heightremains continuously illuminated until the new targetheight is reached whereupon the old height LED isextinguished and the new height LED is continuouslyilluminated.

It should be noted that if any of the side doors or thetailgate are open when the vehicle speed is less than5 mph (8 km/h), all height changes are suspendeduntil the doors and tailgate are closed. If a door hasbeen open for more than 30 seconds, then thesystem will need “reminding” of the new height afterthe door has been closed. This condition is indicatedby the LEDs for the old and new heights both beingcontinously illuminated.

Application of the footbrake also causes any heightchanges to be suspended whilst it is pressed. If thefootbrake has been applied continously for morethan 3 minutes, then height changes are allowed toresume.

The ride height of the vehicle is correctly maintainedonly whilst the engine is running. To compensate forany changes in load after parking (e.g. driver orpassengers getting out),the EAS system will lower

the vehicle to the height of the lowest corner afterthe last door is closed. Furthermore, if the vehicleshould develop a lean due to temperature effects orair leakage whilst parked, the EAS system isautomatically re–powered every few hours to allowlimited corrections to the height to be achieved.

SECURITY/CENTRAL LOCKING S3

CIRCUIT OPERATION 1

CIRCUIT OPERATION

Basic Overview – Central Door Locking

All new Range Rover models feature Central DoorLocking.

All four doors and the tailgate can be locked andunlocked through operation of the central lockingsystem, which can be operated by:

Pressing down, or lifting up, either of the frontdoor sill buttons.

Turning the key clockwise (to lock), or turning thekey anti–clockwise (to unlock), with the key inthe drivers door lock.

Pressing the “lock” button, or pressing the “un-lock” button, on the remote handset.

The new Range Rover is also equipped with a“Superlocking” feature. When the vehicle is“Superlocked”, it is impossible to unlock any of thedoors from inside the vehicle by lifting any of the sillbuttons.

Basic Overview – Alarm

All new Range Rovers are equipped with asophisticated integrated security system.

The alarm system offers the following forms ofprotection:

Perimetric protection against unauthorised open-ing of any of the hinged “slam” panels.

Engine crank inhibit against unauthorised enginecrank.

Electronic engine immobilisation against unau-thorised engine start.

Volumetric protection against intrusion into thepassenger compartment.

Basic Overview – Lazy Locking

An additional feature of the new Range Rover’ssecurity system is Lazy Locking.

Lazy Locking enables the driver to close any openglass panel (window or sunroof) from outside the carusing either the key or the remote handset.

Lazy Locking can be carried out either when lockingor super locking the vehicle, or when the vehicle isalready in a locked state.

N.B. Activation of a lazy locking sequence will bedependent on market requirements.

General

The vehicle locking and security system comprisesthe following components:

“C” type latches on the passenger doors incorpo-rating central door locking, superlocking andslam locking facilities.

An external key barrel on the driver’s door, allow-ing central door locking, superlocking and un-locking, with mechanical override via key (ex-cluding superlocking) in the event of a powerfailure.

Separately controlled central door locking actua-tors on tailgate and fuel filler flap.

Ultrasonic movement detector, located over theLH “B” post.

Passive Immobilisation Coil (Z270) (Not on allvehicles).

Under bonnet mounted alarm klaxon (Not on allvehicles).

Battery Backed Up Alarm Sounder (Z272) (Noton all vehicles).

Radio Frequency remote key allowing locking,superlocking, unlocking and lazy locking.

Inertia switch allowing unlocking in the event of acrash.

Security LED to indicate the “alarm active” state.

Page 298: Electronic Troubleshooting Manual RR-P38 eng

SECURITY/CENTRAL LOCKINGS3

CIRCUIT OPERATION2

Remote Handset Operation

The handset has two buttons, lock/superlock andunlock. The operation is as follows:

Lock – single press of lock button.

Superlock – double press of lock button (within 1 second).

Unlock – single press of unlock button fromeither locked or superlocked.

Lazy lock – press and hold lock button for morethan 1 second.

(NB Hold on second press if superlock requiredas well.)

Lazy Seats – press unlock button for more than1 second.

(NB This will unlock as well.)

Locking operation

There are six different ways to lock a new RangeRover. These are:

Sill Locking

Depressing either of the front door sill buttons whileboth front doors are closed will result in all the doorsand the tailgate locking, and the vehicle entering asill locked state.

In this state the alarm remains inactive (provides noprotection), with no LED flash.

Sill locking can be achieved independently of key–inand ignition switch status.

Slam Locking:

Depressing either of the front door sill buttons witheither front door open, will result in all the doors andthe tailgate locking and the vehicle entering a slamlocked state.

Following a slam locking operation, the alarm willenter the perimetric mode, engine crank will bedisabled and electronic engine immobilisation will beactivated.

Attempting to slam lock the vehicle with either thekey in the ignition, or the ignition on, will causeunlocking of all the doors.

Key Locking

A single turn of the key towards the front of thevehicle will result in all the doors and tailgate locking.

The alarm will enter the perimetric mode, enginecrank will be disabled and electronic engineimmobilisation will be activated.

Key Superlocking

A double turn of the key in a clockwise direction (i.e.towards the front of the vehicle) within 2 seconds,provided the doors, tailgate and bonnet are closed,will result in all the doors being superlocked.

The alarm will enter the perimetric mode, enginecrank will be disabled and electronic engineimmobilisation will be activated.

Remote Locking

A single press of the lock button on the remotehandset will result in all the doors and the tailgatelocking.

The alarm will enter the perimetric mode, enginecrank will be disabled and electronic engineimmobilisation will be activated.

Remote Superlocking

A double press of the lock button on the remotehandset within 2 seconds, provided the doors,tailgate and bonnet are closed, will result in all thedoors being superlocked (subject to ultrasonic lookaround – see Ultrasonic Sensor).

Providing all the windows are closed, the perimetricand volumetric alarm will be set. If all the windowsare not closed, then only the perimetric alarm will beset.

Engine crank will be disabled and electronic engineimmobilisation will be activated.

Page 299: Electronic Troubleshooting Manual RR-P38 eng

SECURITY/CENTRAL LOCKING S3

CIRCUIT OPERATION 3

Lazy Locking

Lazy locking can be carried out when either lockingor superlocking, or when the vehicle is already in alocked state, by either holding the key turned to thelock position or by holding the remote handset lockbutton pressed for more than one second.

This will cause all the open windows to start closingsimultaneously. Closure of the windows will befollowed by closure of the sunroof.

Dependent upon market requirements, lazy lockingwill either operate in one–shot mode, or in deadman’s handle mode.

In one–shot mode, the windows and sunroof willcontinue to close even after the key has beenreleased from the lock position, or the lock but-ton on the remote handset has been released.

In dead man’s handle mode, closure of the win-dows and sunroof will only continue for as longas the key is held to the lock position, or the lockbutton is pressed on the remote handset. In thiscase, failure of any of the apertures to be fullyclosed upon release of the key/button will resultin a mislock.

Mislock

A mislock condition is indicated by either two short“beeps” from the alarm sounder, or by three shortflashes of the courtesy lights, depending on themarket legislation.

Partial Arming Of The Perimetric Alarm

If the perimetric alarm is armed with one (or more) ofthe doors, or the tailgate, or the bonnet open, thenthe remaining panels are all protected by the alarm.If any of the open panels are subsequently closed,then they too will be protected by the alarm.

Security LED

The security LED has two functions:

Firstly for the initial ten seconds after a lock re-quest, it provides visual confirmation of the lockstatus.

Secondly, after this confirmation period, it acts asa deterrent to any theft attempt, (flashing at aslower rate).

Volumetric Protection

Volumetric protection, (protection of the vehicle’sinterior), is provided by an Ultrasonic Sensor andan Ultrasonic detector .

If the vehicle has been successfully superlocked withthe key, then provided all the windows are closed, a

single press on the remote transmitter lock buttonwill activate the ultrasonics. There is a 5 secondsettling period before movement can be detected.

Page 300: Electronic Troubleshooting Manual RR-P38 eng

SECURITY/CENTRAL LOCKINGS3

CIRCUIT OPERATION4

Audible/Visual Warnings

When an intrusion is detected, the Alarm Sounder(Z171) will sound and visual indicators will flash. Theoutput from the sounder is either pulsed or acontinuous tone, depending on market legislation. Ifthe output is pulsed, then its status will besynchronised with that of the visual indicators.

The lamps used for external visual indication aredependent upon market legislation, but will be eitherHazards, or Side and Tail, or Dip and Tail.

Two different types of Alarm Sounders are available:

1. Normal Alarm Klaxon (Alarm Sounder (Z171))

2. Battery Backed Up Alarm Sounder (Z272)

The Battery Backed Up Alarm Sounder (Z272) is analarm sounder which contains its own internalbattery. When the ignition is on, the internal batteryis charged via an ignition feed. If either the connectoris removed or the wires to it are cut, then thesounder will sound for 4.5 minutes.

To disconnect the Battery Backed Up Alarm Sounder(Z272):

Turn Ignition On (Pos. II).

Turn Ignition Off.

Disconnect within 17 seconds.

To silence if triggered:

Connect.

Disarm Alarm.

Turn Ignition On (Pos. II).

Alarm Triggering

The perimetric alarm will be triggered by any of thedoors opening, the tailgate opening, the bonnetopening, the ignition key being inserted, the ignitionbeing turned on, or the inertia switch being tripped.

The volumetric alarm will be triggered by anymovement within the passenger compartment.

The alarm will be triggered a maximum of threetimes during any set/unset period. Any furthertriggers after this will be ignored.

ENGINE IMMOBILISATION FUNCTION

The engine will be immobilised whenever the alarmis armed or the alarm enters the PassiveImmobilisation mode (regardless of whether or notthe theft alarm is armed). There are two methods ofEngine Immobilisation featured:

1. Engine Crank Disable

2. Electronic Engine Immobilisation

The electronic engine immobilisation is controlledjointly by the engine management system’sElectronic Control Module and the BeCM.

If a crank signal is detected when the engine isimmobilised, the “Engine Immobilised” message willbe transmitted to the instrument pack, and it will notbe possible to start the engine.

Engine Immobilisation (Petrol)

The BeCM mobilises the engine by transmitting anengine mobilise code to the ECM. The code is notsent when the engine is immobilised.

Engine Immobilisation (Diesel)

The electronic engine immobilisation feature fitted tothe diesel engine derivatives is different to thesystem fitted to the petrol versions.

The BeCM mobilises the engine by holding theengine mobilise output high. The output will be lowwhen the engine is immobilised.

Page 301: Electronic Troubleshooting Manual RR-P38 eng

SECURITY/CENTRAL LOCKING S3

CIRCUIT OPERATION 5

Passive Immobilisation

The following conditions will passively immobilise thevehicle:

30 seconds after ignition has been turned off andthe driver’s door has been opened.

30 seconds after ignition has been turned off, thekey removed, and the driver’s door has beenopened.

10 minutes after ignition has been turned off andthe key removed (without opening the driver’sdoor).

The handset becomes desynchronised (or withan improperly functioning handset).

The vehicle can be mobilised by any of the followingmethods:

Turn the ignition on (The handset must be func-tioning properly and within close proximity to thekey!)

Press unlock button on the handset

Enter EKA code

NOTE: The vehicle will remain immobilised byattempting to turn the ignition on with the handsetdetached from the key ring (or with an improperlyfunctioning handset).

If the handset becomes desynchronised (or isfunctioning improperly), the engine will be passivelyimmobilised. If an attempt is made to start theengine, the message “Engine Disabled, PressRemote” will be displayed on the message centre. Tomobilise the engine the EKA code must be enteredand the handset (when functioning properly)resynchronised.

Passive Immobilisation Coil (Z270)

A magnetic field is generated by the passiveImmobilisation Coil (Z270) contained in the steeringcolumn. This field excites a receiving coil in thehandset causing it to transmit a mobilisation signal tothe BeCM. If the BeCM does not receive this signalfrom the handset, the vehicle will remainimmobilised.

Handset Transmitter Resynchronisation

The Theft Alarm Unit (Z163) will remainsynchronised with the handset unless:

The handset’s batteries have been removed.

The vehicle’s battery has been disconnected.

NOTE: All handsets must be resynchronised whenthe vehicle’s battery has been disconnected.

A handset may be resynchronised by performing akey lock, or unlock, on either front door within 30seconds of performing a remote lock, superlock, orunlock function. The BeCM uses the change of stateof the CDL Switch to initiate resynchronisation.

Emergency Key Access (EKA)

EKA is used to disarm the theft alarm and mobilisethe vehicle in the event of a handset failure. This ispossible through a series of locks and unlocks withthe key in the driver’s door lock cylinder. With thevehicle locked and the alarm armed, turn the key therequired number of times according to the followingsequence:

1. To enter the first digit, turn the key the requirednumber of times to the unlock position.

2. To enter the second digit, turn the key the re-quired number of times to the lock position.

3. To enter the third digit, turn the key the requirednumber of times to the unlock position.

4. To enter the fourth digit, turn the key the requirednumber of times to the lock position.

5. Turn the key to the unlock position to unlock thedoors, disarm the alarm, and mobilise the ve-hicle.

NOTE: The key must be fully turned to the rest andlock/unlock position each time.

After 5 wrong attempts, you must wait 10 minutes.
