Condition
Some customers may comment on one or more of the following concerns:
-
The door ajar message stays on or comes on intermittently.
-
The interior lights stay on or turn on intermittently.
-
The content theft deterrent alarm goes off intermittently.
-
RAP does not cancel when the door is opened allowing the radio, power windows, sunroof and the compass to remain powered up.
-
The battery is discharged.
Cause
These conditions may be caused by water intrusion into the door ajar switch (part of the door lock assembly) which causes an incorrect switch status
input to the BCM. This condition can be intermittent and wet weather may aggravate this condition.
Correction
Use the following steps to aid in diagnosis of the concern.
Important
DO NOT replace the body control module (BCM) for this concern.
1. Use the Tech 2(R) and monitor the door ajar switch inputs to the BCM. The Tech 2(R) lists the left front door separately, then all passenger doors
together.
2. Check if a door ajar message is active with the doors closed. If this condition is not present, washing the vehicle may induce the concern. Note that
the vehicle may have to sit for up to two hours.
3. If the concern is the RAP does not cancel when the left front door is opened, suspect the left door lock assembly. If the door ajar message is active
on the passenger door, it could be any of the other doors.
4. Try opening and closing each passenger door one at a time while monitoring the door ajar status to see if one of the doors will cause the message
to change to door closed. If it does, suspect that door lock.
5. If the message does not change, you can isolate which door is indicating ajar by disconnecting the individual door electrical connector at the
pass-through on the pillar side. Always start with the right front door first. If the message changes to door closed when the door is disconnected,
suspect that door lock.
Once you have identified the suspect door, refer to SI for complete circuit testing. Refer to Diagnostic Starting Point - Vehicle Access in SI.
