Remote Keyless Entry (RKE) Condition

Use an analog voltmeter for the following test.

Remote Keyless Entry General Checks Before Other Checks.
1. Check if door locks operate properly. If not OK, repair as necessary
2. Test transmitter operation. If not functional, test transmitter batteries for at least six volts. If not OK, replace batteries as necessary. Retest transmitter operation.

Remote Keyless Entry Module:

3. Disconnect the wire connectors at the RKE module Using a ohmmeter check for continuity between the Pins of the wire connectors :
- Pin 1 to Pin 4 of the gray connector.
- Pin 2 to Pin 3 of the gray connector.
- Pin 1 of the black connector to Pin 3 of the gray connector.
If no continuity repair as necessary.
4. Using a voltmeter, check the wire connectors for battery feed and ignition feed:
- Check Pin 2 of the black connector for battery feed.
- Check Pin 8 of the black connector for ignition feed with the ignition key in the ON position.
If not OK, check and repair as necessary
5. Using a ohmmeter, check the Pin 8 of the black connector for continuity to ground.If not OK, check and repair as necessary.
6. Check if module is programmed properly Refer to Program Remote Keyless Entry Module. If module will not program check for continuity between Pin 4 of the black connector to the programming line connector. If no continuity repair as necessary.
7. Check if horn operates properly If not OK, repair as necessary

Driver Door Will Not Unlock With The Transmitter
1. Using an analog voltmeter, connect the meter to Pin 1 of the black connector and to ground. Press the unlock button once and check for a voltage pulse.
2. If no voltage pulse is measured, replace the receiver. If voltage pulse is measured, check the wiring to the driver door and repair as necessary.

Driver Door Will Unlock With The Transmitter, But All Other Doors Will Not Unlock
1. Using an analog voltmeter, connect the meter to Pin 3 of the gray connector and to ground. Press the unlock button twice within five seconds and check for a voltage pulse.
2. If no voltage pulse is measured, replace the receiver. If voltage pulse is measured, check the wiring to the passenger door lock motors and repair as necessary.

All Doors Will Not Lock With The Transmitter
1. Using an analog voltmeter, connect the meter to Pin 1 of the gray connector and to ground.Press the lock button and check for a voltage pulse.
2. If no voltage pulse is measured, replace the receiver. If voltage pulse is measured, check the wiring to the door lock motors and repair as necessary.

Doors Will Lock Using The Transmitter But There Is No Horn Chirp
1. See Service Procedures, Horn Chirp Cancellation.
2. Using an analog voltmeter, connect the meter to Pin 6 of the gray connector and to ground.Press the lock button and check for a voltage pulse decrease.
3. If no voltage pulse decrease is measured, replace the receiver. If voltage OK, repair circuit to the horn relay as necessary.

Illuminated Entry Fails To Work In Initial Unlocking With Transmitter
1. Using an analog voltmeter, connect the meter to Pin 6 of the black connector and to ground.Press the lock button and check for a voltage pulse decrease.
2. If no voltage pulse decrease is measured, replace the receiver. If voltage OK, repair circuit to the dome as necessary.

Parking Lamps and/or Head Lamps Fail To Flash With Panic Button
1. Using an analog voltmeter, connect the meter to Pin 5 of the gray connector and to ground to test parking lamps out put. Press the panic button and check for a voltage pulse.
2. If no voltage pulse is measured, replace the receiver. If voltage OK, repair circuit to the parking lamps as necessary.
3. Connect the meter to Pin 5 of the black connector and to ground to test head lamps out put. Press the panic button and check for a voltage pulse.
4. If no voltage pulse is measured, replace the receiver. If voltage OK, repair circuit to the head lamps as necessary.
