HOW TO USE THIS MANUAL B

This manual provides information on the electrical circuits installed on vehicles bydividing them into a circuit for each system.

The actual wiring of each system circuit is shown from the point where the powersource is received from the battery as far as each ground point. (All circuitdiagrams are shown with the switches in the OFF position.)

When troubleshooting any problem, first understand the operation of the circuitwhere the problem was detected (see System Circuit section), the power sourcesupplying power to that circuit (see Power Source section), and the ground points(see Ground Point section). See the System Outline to understand the circuitoperation.

When the circuit operation is understood, begin troubleshooting of the problemcircuit to isolate the cause. Use Relay Location and Electrical Wiring Routingsections to find each part, junction block and wiring harness connectors, wiringharness and wiring harness connectors, splice points, and ground points of eachsystem circuit. Internal wiring for each junction block is also provided for betterunderstanding of connection within a junction block.Wiring related to each system is indicated in each system circuit by arrows(from__, to__). When overall connections are required, see the Overall ElectricalWiring Diagram at the end of this manual.

Current is applied at all times through the STOP fuse to TERMINAL 2 of the stop light SW.When the ignition SW is turned on, current flows from the GAUGE fuse to TERMINAL 8 of the light failure sensor, and also flowsthrough the rear lights warning light to TERMINAL 4 of the light failure sensor.

Stop Light Disconnection WarningWhen the ignition SW is turned on and the brake pedal is pressed (Stop light SW on), if the stop light circuit is open, the currentflowing from TERMINAL 7 of the light failure sensor to TERMINALS 1, 2 changes, so the light failure sensor detects thedisconnection and the warning circuit of the light failure sensor is activated.As a result, the current flows from TERMINAL 4 of the light failure sensor to TERMINAL 11 to GROUND and turns the rear lightswarning light on. By pressing the brake pedal, the current flowing to TERMINAL 8 of the light failure sensor keeps the warningcircuit on and holds the warning light on until the ignition SW is turned off.

VOLTAGE CHECK

(a) Establish conditions in which voltage is present at the checkpoint.Example:

[A] – Ignition SW on[B] – Ignition SW and SW 1 on[C] – Ignition SW, SW 1 and Relay on (SW 2 off)

(b) Using a voltmeter, connect the negative lead to a good groundpoint or negative battery terminal, and the positive lead to theconnector or component terminal.This check can be done with a test light instead of a voltmeter.

CONTINUITY AND RESISTANCE CHECK

(a) Disconnect the battery terminal or wire so there is no voltagebetween the check points.

(b) Contact the two leads of an ohmmeter to each of the checkpoints.

If the circuit has diodes, reverse the two leads and checkagain.When contacting the negative lead to the diode positive sideand the positive lead to the negative side, there should becontinuity.When contacting the two leads in reverse, there should be nocontinuity.

(c) Use a volt/ohmmeter with high impedance (10 kΩ/Vminimum) for troubleshooting of the electrical circuit.

FINDING A SHORT CIRCUIT

(a) Remove the blown fuse and disconnect all loads of the fuse.(b) Connect a test light in place of the fuse.(c) Establish conditions in which the test light comes on.

Example:[A] – Ignition SW on[B] – Ignition SW and SW 1 on[C] – Ignition SW, SW 1 and Relay on (Connect the

Relay) and SW 2 off (or Disconnect SW 2)

(d) Disconnect and reconnect the connectors while watching thetest light.The short lies between the connector where the test lightstays lit and the connector where the light goes out.

(e) Find the exact location of the short by lightly shaking theproblem wire along the body.

CAUTION:(a) Do not open the cover or the case of the ECU unless

absolutely necessary. (If the IC terminals are touched,the IC may be destroyed by static electricity.)

(b) When replacing the internal mechanism (ECU part) ofthe digital meter, be careful that no part of your body orclothing comes in contact with the terminals of leadsfrom the IC, etc. of the replacement part (spare part).

DISCONNECTION OF MALE AND FEMALECONNECTORS

To pull apart the connectors, pull on the connector itself, notthe wire harness.

Vehicle Speed Sensor(Combination Meter)


65

The engine control system utilizes a microcomputer and maintains overall control of the engine, etc. An outline of enginecontrol is given here.

1. Input Signals(1) Engine coolant temp. signal system

The engine coolant temp. sensor detects the engine coolant temp. and has a built–in thermistor with a resistance whichvaries according to the engine coolant temp. Thus the engine coolant temp. is input as a control signal to TERMINALTHW of the engine control module.

(2) Intake air temp. signal systemThe intake air temp. sensor is installed in the mass air flow meter and detects the intake air temp., which is input as acontrol signal to TERMINAL THA of the engine control module.

(3) Power steering oil pressure signal systemPower steering oil pressure is detected by the power steering oil pressure SW and is input as a control signal toTERMINAL PSW of the engine control module.

(4) RPM signal systemCamshaft position and crankshaft position are detected by the camshaft position sensor and crankshaft position sensor.Camshaft position is input as a control signal to TERMINAL G2+ of the engine control module, and engine RPM is inputinto TERMINAL NE+.

(5) Throttle signal systemThe throttle position sensor detects the throttle valve opening angle, which is input as a control signal to TERMINAL VTAof the engine control module.

(6) Vehicle speed signal systemThe vehicle speed is detected by the ABS speed sensor and the signal is input to TERMINAL SPD of the engine controlmodule via the comb. meter and the skid control ECU with actuator. (w/ ABS)The vehicle speed is detected by the vehicle speed sensor installed in the transaxle and the signal is input toTERMINAL SPD of the engine control module via the comb. meter. (w/o ABS)

(7) NSW signal system (A/T)The Park/Neutral position SW detects whether the shift position is in neutral or not, and inputs a control signal toTERMINAL NSW of the engine control module.

(8) A/C SW signal systemThe operating voltage of the A/C SW is detected and is input as a control signal to TERMINAL A/CS of the enginecontrol module.

(9) Battery signal systemVoltage is constantly applied to TERMINAL BATT of the engine control module. When the ignition SW is turned to on,voltage for engine control module operation is applied via the EFI relay to TERMINAL +B of the engine control module.

(10) Intake air volume signal systemIntake air volume is detected by the mass air flow meter, and is input as a control signal to TERMINAL VG of the enginecontrol module.

(11) STA signal systemTo confirm that the engine is cranking, the voltage applied to the starter motor during cranking is detected and is input asa control signal to TERMINAL STA of the engine control module.

(12)Oxygen sensor signal systemThe oxygen density in the exhaust gases is detected and is input as a control signal into TERMINALS OX1A and OX1Bof the engine control module. To maintain stable detection performance by the oxygen sensor, a heater is used forwarming the sensor. The heater is also controlled by the engine control module (HT1A and HT1B).

(13)Engine knock signal systemEngine knocking is detected by the knock sensor and input as a control signal to TERMINAL KNK1 of the engine controlmodule.

(14)Electrical load signal systemWhen systems which cause a high electrical load such as the rear window defogger, taillight are turned on, a signal isinput to TERMINALS ELS and ELS2 as a control signal.

(15)Vapor pressure signal systemVapor pressure is detected by the vapor pressure sensor and is input as a control signal to TERMINAL PTNK of theengine control module.

Engine Control

2. Control System∗ SFI system

The SFI system monitors the engine conditions through the signals, which are input from each sensor to the enginecontrol module. Based on this data and the program memorized in the engine control module, the most appropriate fuelinjection timing is decided and current is output to TERMINALS #10, #20, #30 and #40 of the engine control module,operating the injectors (to inject fuel). This is the system which finely controls the fuel injection in response to the drivingconditions, through the engine control module.

∗ ESA systemThe ESA system monitors the engine conditions using the signals, which are input to the engine control module from eachsensor. Based on this data and the program memorized in the engine control module, the most appropriate ignition timingis decided and current is output to TERMINALS IGT1, IGT2, IGT3 and IGT4 of the engine control module. This outputcontrols the ignition coil and igniter No. 1 , No. 2 , No. 3 and No. 4 to produce the most appropriate ignition timing for thedriving conditions.

∗ IAC systemThe IAC system increases the RPM and provides idle stability for fast idle–up when the engine is cold, and when the idlespeed has dropped due to electrical load and so on. The engine control module evaluates the signals from each sensor,and outputs current to TERMINAL RSO to control the idle air control valve.

∗ Knock control systemKnock control system controls the gate based on the engine rotation speed and detects knocking by the peak value of theknock sensor output during the gate open period, and then controls it to the most suitable ignition timing in proportion tothe driving condition.

∗ Evapoparge control systemThis system leads the vapor stuck to the canister to the serge tank in order not to agitate the air fuel by adjusting the fuelinjection volume.The signal at this time will be output from TERMINAL EVP of the engine control module to VSV (EVAP).

3. Diagnosis SystemWith the diagnosis system, when there is a malfunctioning in the engine control module signal system,the malfunctionsystem is recorded in the memory. The malfunctioning system can be found by reading the display (Code) of the malfunctionindicator lamp.

4. Fail–Safe SystemWhen a malfunction occurs in any system, if there is a possibility of engine trouble being caused by continued control basedon the signals from that system, the fail–safe system either controls the system by using the data (Standard values)recorded in the engine control module memory or else stops the engine.

The current is always flowing from the HEAD MAIN fuse to HEAD relay (Coil side) to TERMINAL 6 of the daytime runninglight relay, from ECU–B fuse to TERMINAL 3 of the daytime running light relay and from the TAIL fuse to TAIL relay (Coilside) to TERMINAL 14 of the daytime running light relay (USA).When the ignition SW is turned on, the current flowing through the GAUGE fuse flows to TERMINAL 12 of the daytimerunning light relay.

1. Daytime Running Light OperationWhen the engine is started, voltage generated at TERMINAL L of the generator is applied to TERMINAL 8 of the daytimerunning light relay. If the parking brake lever is pulled up (Parking brake SW on) at this time, the relay is not activated so thedaytime running light system does not operate. If the parking brake lever is then released (Parking brake SW off), a signal isinput to TERMINAL 11 of the relay.This activates the daytime running light relay and the HEAD relay is turned to on, so the current flows from the HEAD MAINfuse to the HEAD relay (Point side) to HEAD LH LWR, HEAD RH LWR fuses to TERMINAL 2 of the headlights to TERMINAL1 to TERMINAL 1 of the daytime running light relay to TERMINAL 2 to GROUND, causing the headlights to light up(Headlights light up dimmer than normal brightness.). Once the daytime running light system operates and the headlightslight up, the headlights remain on even if the parking brake lever is pulled up (Parking brake SW on).If the engine stalls and the ignition SW remains on, the headlights remain light up even through current is no longer outputfrom TERMINAL L of the generator. If the ignition SW is then turned off, the headlights go off.If the engine is started with the parking brake lever released (Parking brake SW off), the daytime running light systemoperates and headlights light up when the engine starts.

2. Headlight OperationWhen the light control SW is switched to Head position and the dimmer SW is set to Low position, causing the daytimerunning light relay and the HEAD relay to turn on, so the current flows from the HEAD MAIN fuse to HEAD relay (Coil side) toTERMINAL 6 of the daytime running light relay to TERMINAL 7 to TERMINAL 12 of the light control SW to TERMINAL 11 toGROUND. The current to HEAD relay (Point side) then flows to HEAD LH LWR, HEAD RH LWR fuses to TERMINAL 2 of theheadlights (Low) to TERMINAL 1 to TERMINAL 1 of the daytime running light relay to TERMINAL 2 to GROUND, causingthe headlights to light up at normal intensity.When the light control SW is switched to Head position and the dimmer SW is set to High position, the signal from thedimmer SW is input to the daytime running light relay. This activates the daytime running light relay and the HEAD relay isturned on, so the current flows from the HEAD MAIN fuse to HEAD relay (Point side) to TERMINAL 1 of the DIMMER relay toTERMINAL 2 to TERMINAL 13 of the daytime running light relay, activating the DIMMER relay. This causes current to flowfrom TERMINAL 3 of the DIMMER relay to TERMINAL 5 to HEAD LH UPR, HEAD RH–UPR fuses to TERMINAL 2 of theheadlights (High) to TERMINAL 1 to GROUND, causing the headlights to light up at high beam and the high beam indicatorlight to light up.When the dimmer SW is switched to Flash position, the signal from the dimmer SW is input to the daytime running light relay.This activates the daytime running light relay and the HEAD relay is turned on, so the current flows from the HEAD MAINfuse to HEAD relay (Point side) to TERMINAL 1 of the DIMMER relay to TERMINAL 2 to TERMINAL 13 of the daytimerunning light relay, activating the DIMMER relay, and also flows from the HEAD LH UPR, HEAD RH UPR fuses toTERMINAL 2 of the headlights to TERMINAL 1 to GROUND, causing the headlights to light up at high beam and the highbeam indicator light to light up.

3. Automatic Light Control Operation (USA)When the daytime running light is operating and the Automatic control sensor detects a decrease in the ambient light, theautomatic light control operation starts. At the same time, daytime running light relay is activated, so current flows from theTAIL fuse to the TAIL relay (Coil side) to TERMINAL 14 of the daytime running light relay, and the HEAD MAIN fuse to theHEAD relay (Coil side) to TERMINAL 6 of the daytime running light relay, activating both the TAIL relay and the HEAD relay,so that the taillights and headlights light up.When the automatic light control sensor detects an increase in the ambient light, the ignition SW is turned to off, the lightcontrol SW is turned to Head position, and the automatic light control operation stops.

With the ignition SW turned on, the current flows to TERMINAL 8 of the wiper and washer SW, TERMINAL 2 of the frontwiper motor through the WIPER fuse, and the current flows to TERMINAL 2 of the washer motor through the WASHER fuse.

1. Low Speed PositionWith wiper SW turned to LO position, the current flows from TERMINAL 8 of the front wiper and washer SW to TERMINAL 7to TERMINAL 1 of the front wiper motor to TERMINAL 5 to GROUND and causes to the front wiper motor to run at lowspeed.

2. High Speed PositionWith wiper SW turned to HI position, the current flows from TERMINAL 8 of the front wiper and washer SW to TERMINAL 9to TERMINAL 4 of the front wiper motor to TERMINAL 5 to GROUND and causes to the wiper motor to run at high speed.

3. INT PositionWith wiper SW turned to INT position, the relay operates and the current which is connected by relay function flows fromTERMINAL 8 of the front wiper and washer SW to TERMINAL 5 to GROUND. This flow of current operates the intermittentcircuit and the current flows from TERMINAL 8 of the front wiper and washer SW to TERMINAL 7 to TERMINAL 1 of the frontwiper motor to TERMINAL 5 to GROUND and the functions.The intermittent operation is controlled by the charge/discharge function of the condenser installed in the relay, and theintermittent time is controlled by a time control SW (w/ intermittent volume SW) to change the charging time of thecondenser.

4. MIST PositionWith wiper SW turned to MIST position, the current flows from TERMINAL 8 of the front wiper and washer SW to TERMINAL7 to TERMINAL 1 of the front wiper motor to TERMINAL 5 to GROUND and causes to the front wiper motor to run at lowspeed.

5. Washer Continuous OperationWith the washer SW turned to on, the current flows from TERMINAL 2 of the washer motor to TERMINAL 1 to TERMINAL 4of the front wiper and washer SW to TERMINAL 5 to GROUND and causes to the washer motor to run, and the windowwasher jet operates. This causes the current to flow to washer continuous operation circuit in TERMINAL 8 of the front wiperand washer SW to TERMINAL 7 to TERMINAL 1 of the front wiper motor to TERMINAL 5 to GROUND and the washeroperates continuously.

Power Window

When the ignition SW is turned on, the current flows through the GAUGE fuse to TERMINAL 1 of the P/W relay toTERMINAL 2 to GROUND. This activates the relay and the current flows through the POWER fuse to TERMINAL 5 of therelay to TERMINAL 3 to TERMINAL B of the power window master SW, TERMINAL 4 of the power window control SW.

1. Manual Operation (Driver’s Window)With the ignition SW turned on and with the power window master SW (Front LH) in Up position, the current flowing toTERMINAL B of the power window master SW flows to TERMINAL DU of the master SW to TERMINAL 4 of the powerwindow motor to TERMINAL 5 to TERMINAL DD of the master SW to TERMINAL E to GROUND and rotates the powerwindow motor in the up direction. The window ascends only while the SW is being pulled. In down operation, the flows ofcurrent from TERMINAL B of the power window master SW to TERMINAL DD to TERMINAL 5 of the motor to TERMINAL 4to TERMINAL DU of the master SW to TERMINAL E to GROUND, flowing in the opposite direction to manual up operationand rotating the motor in reverse, thus opening the window.

2. Auto Down Operation (Driver’s Window)When the front LH window control SW in the power window master SW is pushed strongly on the down side, current flowsfrom TERMINAL B of the master SW to TERMINAL DD to TERMINAL 5 of the power window motor to TERMINAL 4 toTERMINAL DU of the master SW to TERMINAL E to GROUND. Because the hold circuit inside the master SW keeps therelay on the down side activated, the power window motor continues operating even if the power window master SW isreleased. When the driver’s window is fully opened, the hold circuit turns off and the relay on the down side turns off, andauto down operation is completed.

3. Stopping of Auto Down Operation (Driver’s Window)When the master SW (Front LH) is pulled to the up side during auto down operation, a ground circuit opens in the masterSW and current does not flow from TERMINAL DU of the master SW to TERMINAL E, so the motor stops, causing autodown operation to stop. If the master SW is pulled continuously, the motor rotates in the up direction in manual up operation.

4. Manual Operation (Front RH Window)With the power window control SW (Front RH) pulled to the up side, current flowing from TERMINAL 4 of the power windowcontrol SW flows to TERMINAL 3 to TERMINAL 4 of the power window motor to TERMINAL 5 to TERMINAL 1 of the powerwindow control SW to TERMINAL 2 to TERMINAL PD of the master SW to TERMINAL E to GROUND and rotates the powerwindow motor (Front RH) in the up direction. Up operation continues only while the power window control SW is pulled to theup side. When the window descends, the current flowing to the motor flows in the opposite direction, from TERMINAL 4 toTERMINAL 5, and the motor rotates in reverse. When the window lock SW is pushed to the lock side, the ground circuit tothe passenger’s window becomes open. As a result, even if Open/Close operation of the passenger’s window is attempted,the current from TERMINAL E of the power window master SW is not grounded and the motor does not rotate, so thepassenger’s window can not be operated and window lock occurs.

5. Manual Operation (Rear LH, Rear RH Window)With the power window control SW (Rear LH, rear RH) pulled to the up side, current flowing from TERMINAL 4 of the powerwindow control SW flows to TERMINAL 3 to TERMINAL 5 of the power window motor to TERMINAL 4 to TERMINAL 1 of thepower window control SW to TERMINAL 2 to TERMINAL RLD, RRD of the master SW to TERMINAL E to GROUND androtates the power window motor (Rear LH, rear RH) in the up direction. Up operation continues only while the power windowcontrol SW is pulled to the up side. When the window descends, the current flowing to the motor flows in the oppositedirection, from TERMINAL 5 to TERMINAL 4, and the motor rotates in reverse. When the window lock SW is pushed to thelock side, the ground circuit to the passenger’s window becomes open. As a result, even if Open/Close operation of thepassenger’s window is attempted, the current from TERMINAL E of the power window master SW is not grounded and themotor does not rotate, so the passenger’s window can not be operated and window lock occurs.

Manual Lock OperationWhen the door lock control SW or door key lock and unlock SW are operated to Lock position, a lock signal is input toTERMINAL (A) 9 or (A) 7 of the integration relay and causes the relay to function. The current flows from TERMINAL 1 of therelay to TERMINAL 2 to the door lock motors to TERMINALS (A) 1 and 3 of the relay to TERMINAL 9 to GROUND and thedoor lock motors locks the door.

2. Manual Unlock OperationWhen the door lock control SW or door key lock and unlock SW are operated to Unlock position, an unlock signal is input toTERMINAL (A) 8, (A) 6 or (A) 5 of the integration relay and causes the relay to function. The current flows from TERMINAL 1of the relay to TERMINALS (A) 1 and 3 to the door lock motors to TERMINAL 2 of the relay to TERMINAL 9 to GROUNDand the door lock motors unlocks the door.

3. Double Operation Unlock OperationWhen the door key lock and unlock SW LH is turned to the unlock side, only the driver’s door is unlocked. By turning thedoor key lock and unlock SW LH to the unlock side, a signal is input to TERMINAL (A) 6 of the relay, and if the signal is inputagain within 3 seconds by turning the SW to the unlock side again, current flows from TERMINAL 3 of the integration relay tothe door lock motors to TERMINAL 2 of the relay to TERMINAL 9 to GROUND, causing the door lock motors to operate andunlock the doors.

4. Ignition Key Reminder Operation∗ Operating door lock knob (Operation of door lock motors)

With the ignition key in the cylinder (Unlock warning SW on), when the door is opened and locked using door lock knob(Door lock motor), the door is locked once but each door is unlocked soon by the function of the relay. As a result, thecurrent flows from TERMINAL 1 of the integration relay to TERMINALS (A) 1 and 3 to the door lock motors toTERMINAL 2 of the relay to TERMINAL 9 to GROUND and unlocks all the doors.

∗ Operating door lock control SW or door key lock and unlock SWWith the ignition key in the cylinder (Unlock warning SW on), when the door is opened and locked using door lockcontrol SW or key SW, the door is locked once but each door is unlocked by the function of SW contained in motors,and the signal is input to TERMINAL (A) 19 of the relay. According to this input signal, the current flows from TERMINAL1 of the relay to TERMINALS (A) 1 and 3 to the door lock motors to TERMINAL 2 of the relay to TERMINAL 9 toGROUND and unlocks all the doors.

∗ In case of key less lockWith the ignition the key in the cylinder (Unlock warning SW on), when the unlock function is disturbed, for examplepushing the door lock knob etc., the door holds on lock condition. After closing the door after, door courtesy SW inputsthe signal into TERMINAL 5 or 6 or (A) 13 of the integration relay. By this input signal, the relay works and current flowsfrom TERMINAL 1 of the relay to TERMINALS (A) 1 and 3 to the door lock motors to TERMINAL 2 of the relay toTERMINAL 9 to GROUND and unlocks all the doors.

Door lock control (Lock and unlock) and panic control (TVIP alarm and flash) is performed by remote control, without theignition key inserted in the door key cylinder, using low–power electrical waves emitted by a transmitter.

1. Wireless Door Lock or Unlock Normal OperationWith the ignition key not inserted into the ignition key cylinder (Unlock warning SW off) and all the doors completely closed,when the lock or unlock button (Transmitter) is pushed, the door control receiver receives the electrical waves from thetransmitter, and sends a signal to the integration relay causing it to operate.As a result, the integration relay judges whether the door is locked or unlocked based on the signal from the door lock motorand door unlock detection SW, and sends a signal to switch the condition from lock to unlock or vice versa, causing the doorlock motor to operate.

2. Visual Confirmation of Lock or UnlockIf all doors indicate that they are locked after the lock command, parking lights and taillights will flash once. If any doorindicates that it is open after the unlock command, parking lights and taillights will flash twice.

3. Wireless Door Unlock OperationPushing the unlock button (Transmitter) once, driver’s door is unlocked. Furthermore, pushing the button again within 3seconds, the other doors are unlocked.

4. Automatic Lock OperationWith the ignition key not inserted into the ignition key cylinder (Unlock warning SW off) and all the doors completely closed,after pushing the button (Transmitter) to unlock all the doors, if a door is not opened within 30 seconds, all the doors will beautomatically relocked.

5. Wireless Control Stop FunctionIf a door is open (Door courtesy SW on), a signal is input from the door courtesy SW to the integration relay stoppingwireless door lock or unlock.If the ignition key is in the ignition key cylinder (Unlock warning SW on), the unlock warning SW inputs a signal to theintegration relay stopping wireless door lock or unlock.

6. Repeat FunctionIn case an appropriate lock detection signal is not received after outputting a lock signal when pushing the lock button(Transmitter), 1 seconds later, the integration relay output the lock signal again.

7. Remote Panic OperationPanic will function when doors are locked or unlocked, open or closed. When the panic button (Transmitter) is pushed once,theft alarm sounds and headlights and taillights flash. Then, the panic or the unlock button (Transmitter) is pushed oncemore, sounding and flashing will stop. Panic will not function when ignition key is in ignition key cylinder.

Previous automatic transaxle have selected each gear shift using mechanically controlled throttle hydraulic pressure,governor hydraulic pressure and lock–up hydraulic pressure. The electronically controlled transmission, however, controlsthe line pressure and lock–up pressure etc. electrically, through the solenoid valve. The engine control module controls eachsolenoid valve based on the input signals from each sensor, which makes smooth driving possible by shift selection for eachgear that is most appropriate to the driving conditions at that time.

1. Gear Shift OperationDuring driving, the engine control module selects the shift for each gear which is most appropriate to the driving conditions,based on input signals from the engine coolant temp. sensor to TERMINAL THW of the engine control module, and also theinput signals to TERMINAL SPD of the engine control module from the vehicle speed sensor devoted to the electronicallycontrolled transmission. Current is then output to the electronically controlled transmission solenoid. When shifting to 1stspeed, the current flows from TERMINAL S1 of the engine control module to TERMINAL 3 of the solenoid to GROUND, andfrom TERMINAL S2 of the engine control module to TERMINAL 6 of the electronically controlled transmission solenoid toGROUND, and continuity to the No.1 and No.2 solenoid causes the shift.For 2nd speed, the current flows from TERMINAL S1 of the engine control module to TERMINAL 3 of the solenoid toGROUND, and from TERMINAL S2 of the engine control module to TERMINAL 6 of the solenoid to GROUND, andcontinuity to solenoids No.1 and No.2 causes the shift.For 3rd speed, there is no continuity to No. 1 solenoid, only to No. 2, causing the shift.Shifting into 4th speed (Overdrive) takes place when there is no continuity to both No.1 and No.2 solenoid.

2. Stop Light SW CircuitIf the brake pedal is depressed (Stop light SW on ) when driving in lock–up condition, a signal is input to TERMINAL STP ofthe engine control module, the engine control module operates and continuity to the lock–up solenoid is cut.

3. Overdrive Circuit∗ Overdrive on

When the engine is turned on from ignition off, the engine control module turns the O/D on. When the O/D main SW ispushed while the O/D is off, a signal is input into TERMINAL ODMS of the engine control module, and the O/D is turnedon by the engine control module. In this case, the engine control module controls the gear shift according to the vehicle’sdriving condition, using the O/D range. At this time, the O/D off indicator light is off.

∗ Overdrive offWhen the O/D main SW is pushed while the O/D is on, a signal is input into TERMINAL ODMS of the engine controlmodule, and the O/D is turned off. At this time, the current flows through the O/D off indicator light to TERMINAL ODLP ofthe engine control module. As a result, the O/D off indicator light turns on, and the engine control module controls the gearshift according to the vehicle’s driving condition, without using the O/D range.

Cruise Control

The current is applied at all times through the STOP fuse to TERMINAL 2 of the stop light SW.With the ignition SW turned to on, the current flows through the MAIN fuse to AM2 fuse to ignition SW (IG2) to TERMINAL 32of the combination meter and the current through the ECU–IG fuse flows to TERMINAL 2 of the cruise control ECU.When the ignition SW is on and the CRUISE SW is turned on, a signal is input from TERMINAL 2 of the cruise control SW toTERMINAL 1 of the cruise control ECU. As a result, the cruise control ECU functions and the current flows from the ECU–IGfuse to TERMINAL 2 of the cruise control ECU to TERMINAL 16 of the cruise control ECU to GROUND, and the cruisecontrol system is in a condition ready for operation.At the same time, the current flows through the MAIN fuse to AM2 fuse to ignition SW (IG2) to TERMINAL 32 of the cruiseindicator light to TERMINAL 23 to TERMINAL 5 of the cruise control ECU to TERMINAL 16 to GROUND, causing the cruiseindicator light to light up, indicating that cruise control is ready for operation.

1. Set OperationWhen the CRUISE SW is turned on and the SET SW is pushed with the vehicle speed within the set limit (Approx. 40 km/h,25 mph to 200 km/h, 124 mph), a signal is input to TERMINAL 11 of the cruise control ECU, and the vehicle speed at thetime the SET SW is released is memorized in the ECU as the set speed.

2. Set Speed ControlDuring cruise control driving, the ECU compares the set speed memorized in the ECU with the actual vehicle speed inputinto TERMINAL 12 of the cruise control ECU from the combination meter, and controls the cruise control actuator to maintainthe set speed.When the actual speed is lower than the set speed, the ECU causes the current to the cruise control actuator to flow fromTERMINAL 15 of the cruise control ECU to TERMINAL 1 of the cruise control actuator to TERMINAL 2 to TERMINAL 7 ofthe cruise control ECU. As a result, the motor in the cruise control actuator is rotated to open the throttle valve and thethrottle cable is pulled to increase the vehicle speed. When the actual driving speed is higher than the set speed, the currentto the cruise control actuator flows from TERMINAL 7 of the ECU to TERMINAL 2 of the cruise control actuator toTERMINAL 1 to TERMINAL 15 of the cruise control ECU.This causes the motor in the cruise control actuator to rotate to close the throttle valve and return the throttle cable todecrease the vehicle speed.

3. Coast ControlDuring cruise control driving, while the COAST SW is on, the cruise control actuator returns the throttle cable to close thethrottle valve and decrease the driving speed. The vehicle speed when the COAST SW is turned off is memorized, and thevehicle continues at the new set speed.

4. Accel ControlDuring cruise control driving, while the ACC SW is turned on, the cruise control actuator pulls the throttle cable to open thethrottle valve and increase the driving speed.The vehicle speed when the ACC SW is turned off is memorized and the vehicle continues at the new set speed.

5. Resume ControlUnless the vehicle speed falls below the minimum speed limit (Approx. 40km/h, 25mph) after canceling the set speed by theCANCEL SW, pushing the RES SW will cause the vehicle to resume the speed set before cancellation.

6. Manual Cancel MechanismIf any of the following operations occurs during cruise control operation, the magnetic clutch of the actuator turns off and themotor rotates to close the throttle valve and the cruise control is released.∗ Placing the shift lever to positions except ”D” position (Park/Neutral position SW except ”D” position)(A/T), depressing the

clutch pedal (Cruise control clutch SW off)(M/T). ”Signal is not input to TERMINAL 4 of the ECU”∗ Depressing the brake pedal (Stop light SW on). ”Signal input to TERMINAL 3 of the ECU”∗ Pushing the CANCEL SW (CANCEL SW on). ”Signal input to TERMINAL 1 of the ECU”∗ Pushing the CRUISE SW off ”signal input to TERMINAL 1 of the ECU”.

7. Tap–Up Control FunctionWhen the difference between the actual vehicle speed and the set speed is less than 5 km/h (3 mph), the set speed can beincreased 1.6 km/h (1 mph) each time by operating the RES/ACC SW quickly within 0.6 seconds.

8. Tap–Down Control FunctionWhen the difference between the actual vehicle speed and the set speed is less than 5 km/h (3 mph), the set speed can belowered 1.6 km/h (1 mph) each time by operating the SET COAST SW quickly within 0.6 seconds.

9. Auto Cancel FunctionA) If any of the following operating conditions occurs during cruise control operation, the set speed is erased, current flow tothe magnetic clutch is stopped and the cruise control is released, (CRUISE SW turns off).When this occurs, the ignition SW must be turned off once before the CRUISE SW will turn on.∗ When current continues to flow to the motor inside the actuator in the throttle valve ”OPEN” direction.∗ The motor does not operate despite the motor drive signal being output.B) If any of the following operating conditions occurs during cruise control operation, the set speed is erased, current flow tothe magnetic clutch is stopped and the cruise control is released. (CRUISE SW turn off).When this occurs, the cancel state is cleared as the CRUISE SW will turn on again.∗ Over current to transistor driving the motor or the magnetic clutch.∗ Open circuit in the magnetic clutch.∗ Momentary interruption of vehicle speed signal.∗ Short circuit in the cruise control SW.C) If any of the following conditions occurs during cruise control operation, the set speed is erased and the cruise control isreleased. (The power to the magnetic clutch is cut off until the SET SW is ”ON” again.)∗ When the vehicle speed falls below the minimum speed limit, approx. 40 km/h (25 mph)∗ When power to the cruise control system is momentarily cut off.

10. Automatic Transaxle Control Function (A/T)∗ In overdrive. If the vehicle speed becomes lower than the overdrive cut speed (Set speed minus approx. 4 km/h, 2.5 mph)

during cruise control operation, such as driving up a hill, the overdrive is released and the power is increased to prevent areduction in vehicle speed.

∗ After releasing the overdrive, if the vehicle speed becomes higher than the overdrive return speed (Set speed minusapprox. 2 km/h, 1.2 mph) and the ECU judges by the signals from the actuator’s potentiometer that the upward slope hasfinished, the overdrive is resumed after approximately 2 seconds.

∗ During cruise control driving, the cruise control operation signal is output from the cruise control ECU to the engine controlmodule. Upon receiving this signal, the engine control module changes the shift pattern to normal.To maintain smooth cruise control operation (on a downward slope etc.), the lock–up release of the transaxle when theidling point of the throttle position is ”ON” is forbidden.

ABS

ABS is a brake system designed to improve the operating ability and securing the stability of the vehicle by preventing thelock–up of the vehicle by controlling the wheel cylinder pressure of all the four wheels at the time of sudden braking.

1. Input Signals(1) Speed sensor signal

The speed of the wheels is detected and input to TERMINALS FL+, FR+, RL+, and RR+ of the skid control ECU andactuator.

(2) Stop light SW signalA signal is input to TERMINAL STP of the skid control ECU with actuator when brake pedal is depressed.

2. System OperationWhen the wheels are locked–up, the solenoid inside the actuator is controlled by the signal from the skid control ECU withactuator, and the brake fluid in the wheel cylinder will flow through the reservoir and reduce the hydraulic pressure.While the ABS is in operation, as the skid control ECU with actuator always outputs the operation signal to the pump insidethe actuator, and the brake fluid stored inside the reservoir will be sucked up by the pump inside the actuator and returned tothe master cylinder.When the hydraulic pressure of the wheel cylinder is decompressed or increased until the necessary hydraulic pressure, thesolenoid inside the actuator is controlled by the control signal from the skid control ECU with actuator and as a result,hydraulic pressure of the wheel cylinder will be closed at both the master cylinder and reservoir sides routes, and thehydraulic pressure of the wheel cylinder will be in the hold condition.If increase of the hydraulic pressure volume of the wheel cylinder becomes necessary, the control signals from the skidcontrol ECU with actuator control the solenoid inside the actuator, to resume to the normal condition. Thus the brake fluid ofthe master cylinder will be sent to the wheel cylinder and will increase the hydraulic pressure of the wheel cylinder. At thistime, in the case that the brake fluid is left in the reservoir, it will be sucked up by the pump inside the actuator and will besent to the wheel cylinder.

SRS

NOTICE: When inspecting or repairing the SRS, perform the operation in accordance with the following precautionaryinstructions and the procedure and precautions in the Repair Manual for the applicable model year.

Malfunction symptoms of the SRS are difficult to confirm, so the DTCs become the most important source of informationwhen troubleshooting. When troubleshooting the SRS, always inspect the DTCs before disconnecting the battery.

Work must be started after 90 seconds from when the ignition switch is turned to the ”LOCK” position and thenegative (–) terminal cable is disconnected from the battery.(The SRS is equipped with a back–up power source so that if work is started within 90 seconds fromdisconnecting the negative (–) terminal cable of the battery, the SRS may be deployed.)

When the negative (–) terminal cable is disconnected from the battery, the memory of the clock and audio system will becanceled. So before starting work, make a record of the contents memorized in the audio memory system. When work isfinished, reset the audio systems as they were before and adjust the clock. This vehicle has power tilt and powertelescopic steering, power seat and power outside rear view mirror which are all equipped with memory function.However, it is not possible to make a record of the memory contents. So when the work is finished, it will be necessaryto explain this fact tot the customer, and ask the customer to adjust the features and reset the memory. To avoid erasingthe memory in each memory system, never use a back–up power supply from outside the vehicle.

Before repairs, remove the airbag sensor if shocks are likely to be applied to the sensor during repairs.

Do not expose the steering wheel pad, front passenger airbag assembly, side airbag assembly, seat belt pretensioner,airbag sensor assembly, front airbag sensor assembly or side airbag sensor assembly directly to hot air or flames.

Even in cases of a minor collision where the SRS does not deploy, the steering wheel pad, front passenger airbagassembly, side airbag assembly, seat belt pretensioner, airbag sensor assembly, front airbag sensor assembly and sideairbag sensor assembly should be inspected.

Never use SRS parts from another vehicle. When replacing parts, replace them with new parts.

Never disassemble and repair the steering wheel pad, front passenger airbag assembly, side airbag assembly, seat beltpretensioner, airbag sensor assembly, front airbag sensor assembly or side airbag sensor assembly in order to reuse it.

If the steering wheel pad, front passenger airbag assembly, side airbag assembly, seat belt pretensioner, airbag sensorassembly, front airbag sensor assembly or side airbag sensor assembly has been dropped, or if there are cracks, dentsor other defects in the case, bracket or connector, replace them with new ones.

Use a volt/ohmmeter with high impedance (10 kΩ/V minimum) for troubleshooting the system’s electrical circuits.

Information labels are attached to the periphery of the SRS components. Follow the instructions on the notices.

After work on the SRS is completed, perform the SRS warning light check.

If the vehicle is equipped with a mobile communication system, refer to the precaution in the IN section of the RepairManual.

When the ignition SW is turned to ON position, the current from the ECU–IG fuse flows to TERMINAL 5 of the shift lockcontrol ECU.

Shift Lock MechanismWith the ignition SW at ON position, when a signal that the brake pedal is depressed (Stop light SW on) and a signal that theshift lever is put in P position is input to the ECU, the ECU operates and the current flows from TERMINAL 5 of the ECU toTERMINAL SLS+ of the shift lock solenoid to TERMINAL SLS– to TERMINAL 1 of the ECU to GROUND. This causes theshift lock solenoid to turn on (Plate stopper disengages) and the shift lever can shift into position other than P.

The current is applied at all times to TERMINAL 5 of the combination meter through the DOME fuse.When the ignition SW is turned to ON position, the current flows to TERMINAL 4 of the combination meter through theGAUGE fuse. When the light control SW is turned to Tail or Head position, current is applied to TERMINAL 18 of thecombination meter through the TAIL fuse via the TAIL relay (USA) or the light control SW (Canada).

1. Light Reminder SystemWhen the light control SW is in Tail or Head position, the ignition SW turned to OFF from ON position, and the driver’s dooropened (Door courtesy SW on), the current flows to TERMINAL 4 of the combination meter stops. As a result, thecombination meter is activated and current flows from TERMINAL 5 of the combination meter to TERMINAL 2 to GROUND,the buzzer in the combination meter goes on to remind the light is lighting up.

2. Key Reminder SystemWhen the driver door is opened with the ignition SW off and ignition key remaining in the key cylinder (Unlock warning SWon), a signal is input from the unlock warning SW to TERMINAL 16 of the combination meter, and from the door courtesy SWfront LH to TERMINAL 17 of the combination meter. As a result, the buzzer in the combination meter goes on and warns thedriver that the key is remaining in the key cylinder.

Current is always applied from the DOME fuse to TERMINAL 5 of the combination meter. When the ignition SW is turned toON position, the current from the GAUGE fuse flows to TERMINAL 4 of the combination meter and flows TERMINAL 1 of thefront passenger seat belt warning light.

Seat Belt Warning SystemWhen the ignition SW turned on, a signal is input to the combination meter. To determine whether the driver has fastened theseat belt, a signal is input from the buckle SW LH to TERMINAL 12 of the combination meter. When the seat belt is notfastened, the seat belt warning light in the combination meter blinks, and emits a warning sound.In addition, the front passenger is recognized by a sensor (Occupant detection sensor) is installed in the front passengerseat, and determines whether the seat belt is fastened. When not fastened, the signals from the occupant detection sensoris input to TERMINAL 11 of the combination meter, and the front passenger seat belt warning light blinks.

The current is applied at all times through the RDI FAN fuse to TERMINAL 5 of the FAN NO.1 relay.When the ignition SW is turned on, the current flows through the ECU–IG fuse to FAN NO.1 relay (Coil side) to TERMINAL 6of the engine control module. At the same time as this current flow, the current from ECU–IG fuse flows to the FAN NO.2relay (Coil side) to TERMINAL 3 of the pressure SW.

1. Low Speed OperationWhen the A/C system is operating, the FAN NO.1 Relay is turned on. As a result, the current flows from the RDI FAN fuse toFAN NO.1 relay (Point side) to TERMINAL 2 of the radiator fan motor to TERMINAL 1 to TERMINAL 3 of the FAN NO.2 relayto TERMINAL 4 to TERMINAL 2 of the radiator fan resistor to TERMINAL 1 to GROUND, and the radiator fan motor rotatesat low speed.

2. High Speed OperationWhen the pressure SW is on or engine control module operated, the FAN NO.1 and NO.2 relay is turned on. As a result, thecurrent flows from the RDI FAN fuse to FAN NO.1 relay (Point side) to radiator fan motor to TERMINAL 3 of the FAN NO.2Relay to TERMINAL 5 to GROUND, and the radiator fan motor rotates at high speed.

Current is applied at all times through the HEATER fuse to TERMINAL 5 of the HTR relay.When the ignition SW is turned on, the current flows through the GAUGE fuse to TERMINAL 2 of the HTR relay toTERMINAL 1 to TERMINAL 6 of the blower SW.

1. Heater Blower Motor Operation∗ Low speed operation

When the blower SW is moved to LO position, the current flows to TERMINAL 6 of the blower SW to TERMINAL 5 toGROUND, causing the HTR relay to turn on. This causes the current flows from the HEATER fuse to TERMINAL 5 ofthe HTR relay to TERMINAL 3 to the blower motor to the blower resistor to GROUND, rotating the blower motor at lowspeed.

∗ Medium speed operation (Operation at M1, M2)When the blower SW is moved to M1 position, the current flows to TERMINAL 6 of the blower SW to TERMINAL 5 toGROUND, causing the HTR relay to turn on. This causes the current flows from the HEATER fuse to TERMINAL 5 ofthe HTR relay to TERMINAL 3 to the blower motor to the blower resistor to TERMINAL 2 of the blower SW toTERMINAL 5 to GROUND. At this time, the blower resistance of the blower resistor is smaller than at low speed, so theblower motor rotates at medium low speed.When the blower SW is moved to M2 position, the current flows through the HTR relay to the blower motor to the blowerresistor to TERMINAL 1 of the blower SW to TERMINAL 5 to GROUND. At this time, resistance of the blower resistor issmaller than at M1 position, so the blower motor rotates at medium high speed.

∗ High speed operationWhen the blower SW is moved to HI position, the current flows to TERMINAL 6 of the blower SW to TERMINAL 5 toGROUND, causing the HTR relay to turn on.This causes the current flows from the HEATER fuse to TERMINAL 5 of the HTR relay to TERMINAL 3 to the blowermotor to TERMINAL 4 of the blower SW to TERMINAL 5 to GROUND, rotating the blower motor at high speed.

2. Air Conditioning OperationWhen the blower SW is set on, the current flows from the HTR fuse to the HTR relay (Point side) to the A/C fuse to theTERMINAL 2 of the A/C SW. If the A/C SW is turned on, at this time a signal is input into the engine control module. Thisactivates the engine control module and M/G CLT relay. So that current flows from the A/C fuse to M/G CLT relay (Point side)to A/C magnetic clutch. Causing the compressor to operate.

HTR Relay5–3 : Closed with the ignition SW at ON position and the blower SW on
