mote Control Alarm and Lock System: Testing and Inspection

ection and VerificationECTION AND VERIFICATION

ectronic door lock control system is diagnosed as part of the overall remote control alarm and lock system. To initiate system self test, See:te Control Alarm and Lock System

Verify the vehicle owner's original concern by duplicating the concern.

Vehicle Inspection Chart

Inspect to determine if one of these mechanical or electrical concerns apply. (See Vehicle Inspection Chart)

If the concern(s) remains after the inspection, determine the symptom(s) and proceed to the following symptom chart.

E: For system inspection and verification using New Generation Star (NGS) Tester 007-00500 or equivalent, See: Remote Control Alarm andSystem

E: Voltage and resistance readings can be obtained using Rotunda Digital Volt-Ohmmeter 014-00407 or Rotunda Dwell-Tach-Volt-Ohms Tester0010 or equivalents.

EST AND SERVICE DOOR LOCK SYSTEM:

Check that battery is fully charged (if not, it may be causing the concern)

E: When the battery has been disconnected and reconnected, some abnormal symptoms may occur while the powertrain control module (PCM)50) relearns it's adaptive strategy. The vehicle may need to be driven 16km (10 miles) or more to relearn the strategy.

ciples of Operationte Control Alarm and Lock System

e Remote Alarm and Lock system combines the functions of the Electronic Door Lock Control system and the Vehicle Anti-Theft system into agle module called the receiver assembly. In the New Generation Star (NGS) Tester, the system and module are called RAP which stands formote Anti-Theft Personality.

emote entry receiver assembly, the module performs the following functions:

te Entry (Key Fob)

Unlock driver's doorUnlock all doors and liftgate (40010)Lock all doors and liftgatePanic alarmIssue interior lamps ON (when unlocking) and OFF commands (when locking) to the Generic Electronic Module (GEM)Issue PERSONALITY commands to Memory Seat and Memory Mirror Modules when UNLOCK is pressed on a key fob (Explorer only)

ection and Verification

ction and Verification




receiver assembly communicates on the New Generation Star (NGS) Tester diagnostics interface. Diagnostic testing is controlled by turning onuts, reading inputs, retrieving DTCs, clearing DTCs, direct memory reference and initiating functional tests. Some of the tester's specificbilities are listed below.

Self Test and Fault Code reporting on inputsRecall last eight alarm trigger events (PIDs)Activate all outputsMonitor all inputsTransmitter TIC/Data Menu

Identities all TICs (Transmitter Identification Codes) programmed to the systemIdentifies last TIC and button press received The on-demand self test consists of a module self test and a receiver assembly subsysteminput/output self test. Continuous DTCs are not affected when running an on-demand self test.

E: Do not press any buttons or switches during the on-demand self test.

receiver assembly is well equipped to identify bad inputs, but can do little to diagnose bad outputs. The individual testing the system must look forin outputs to operate during the 10-second self test. The self test should be used for a quick overview of the system to determine if certainystems are operating correctly.

tester PID / DATA menu and the ACTIVE COMMANDS have a full set of tests for alarm and lock systems. Depending upon the option contentvehicle, certain inputs or outputs may not respond because they are not installed at the time of vehicle manufacture.

ow the procedure outlined in Pinpoint Test A: NGS System Diagnostics and On-Line Self Test to start the 10-second receiver assembly self test.

Rotunda New Generation Star (NGS) Tester

unda New Generation Star (NGS) Tester 007-00500 is a menu-driven device that allows self test diagnostics and DTC retrieval.

ace

e NGS Tester communicates to the receiver assembly through the On-Board Diagnostic (OBD-ll) data link connector. The connector is located inpassenger compartment on the driver's side under the steering column.

ving Diagnostic Trouble Codes (DTC)

e receiver assembly monitors the system during normal operation and reports concerns in the form of diagnostic trouble codes (DTCs). The DTCs

be retrieved with the NGS Tester through the communication link.

e following procedure can be used to retrieve DTCs.

1. Turn the ignition switch to OFF.

2. Locate the tester data link located below the steering column.

3. NOTE: Only one multi-pin connector is used. Connect the tester connector to the vehicle data link connector.

4. NOTE: If the message LO BAT appears in the upper left corner of the read-out display and stays on, replace the tester's 9-volt battery beforecontinuing with the on-board diagnostics. The message LO BAT appears momentarily when power switch is turned off.

Turn on the power switch on the right side of the tester. A steady 00 or blank screen signifies that the tester is ready to start the on-boarddiagnostics and receive diagnostic trouble codes.

5. With the ignition switch still off, push the button in the center of the tester.

6. Push the button again. This deactivates the sequence.

7. If the tester passes the above test (00 or blank screen with button in TEST position), proceed with the on-board diagnostic procedure. If anydiagnostic trouble codes appear during the on-board diagnostics, refer to the symptom chart.




8. Connect Rotunda New Generation Star (NGS) Tester 007-00500 or equivalent to the connector located in the engine compartment. Verifythat the tester is in SLOW MODE.

9. Turn on the tester and latch the button down in the TEST position.

10. Turn the ignition switch to RUN.

11. NOTE: Write down all codes. Code 16 indicates system OK. Do not replace anti-lock brake electronic control module.

Read the first code output; after approximately 15 seconds the next code will be output.

meter Identification (PID) Codes

all parameter identification (PID) codes displayed on the NGS Tester are functional on Ranger and Explorer vehicles. Following is a list of thecable PID codes and a description of each code.

Pinpoint Tests

Wiring Connector Probe Points

nfirm a break in the wiring or a poor connection between a blade and terminal at a connector, use Rotunda New Generation Star (NGS) Tester0500 or equivalent to test receiver assembly circuit inputs. Follow these steps:

Turn ignition switch to ON position.Connect the NGS Tester.Select the vehicle type, Data Link, RAP, ACTIVE COMMANDSSelect PID LATCHSelect PlDSSelect the input to be monitored, LATCHIO and then START.Press or activate the switch on the circuit in question and keep it in its active state.LATCHIO is the latch input/output PID. At this point it counts the number of times that any input or output changes state. All other inputs willlock on the first change in state that is seen while on this PID LATCH screen.




Wiggle the wire at the point where connection is questionable.The LATCHIO PID keeps count of all state changes (even after the specific input looks on the first change in value). If there is a looseconnection, the LATCHIO number increase quickly as the wire is wiggled.

ng the Receiver Assembly Harness Hardshells

be the RAP module harness hardshells through the larger "T" shaped holes. Each "T" shaped hole exposes the same terminal as the smaller slottede where the blade enters the hardshell.

Self Test Diagnostic Chart

TE: Forcing large probes, paper clips, etc. into the smaller slots will distort the terminal and create an intermittent connection between the bladethe terminal.
