All Doors Will Not Lock Using Transmitter

  1. 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.
  2. 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.
