All Doors Will Not Lock Using Transmitter
- Unlock driver's door. Using a voltmeter, check for a voltage pulse at BCM Black 20-pin connector terminal No. 6 (Dark Blue/White wire) while pressing UNLOCK button on transmitter. If there is no voltage pulse, replace RKE module. If voltage pulse is present, repair harness between BCM and driver's door latch.
- Check BCM Black 20-pin connector terminals No. 7 (Pink/Black wire), 8 (Pink/Dark Blue wire) and/or 9 (Pink/Light Blue wire) for voltage pulse while pressing transmitter UNLOCK button twice within 5 second interval. If there is no voltage pulse, replace BCM. If voltage pulse is present, repair harness between appropriate BCM terminal and unlock relay.
NOTE:
It may be necessary to press LOCK button several times, voltage pulse only appears for milliseconds.
Using a voltmeter, check BCM Black 20-pin connector terminals No. 11 (Orange/White wire), 12 (Orange/Tan wire) and 13 (Orange/Brown wire) for a voltage pulse while pressing transmitter LOCK button. If there is no voltage pulse, replace BCM. If voltage pulse is present, repair harness between appropriate BCM terminal and lock relay.
