The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.

Condition/Concern:
Intermittently the warning chime may sound, the dome lamp may come on and/or the door locks may cycle. This typically occurs when going over bumps or accelerating. The cause may be the adjustment of the swing gate closing switch.

Recommendation/Instructions:
Using the Tech 2, monitor the BCM input data for the "Passenger Door Ajar Sw.". This input is for all of the passenger doors. It may be necessary to disconnect the swing gate ajar switch to verify it is the source of the concern. If the concern is isolated to the swing gate ajar switch, apply a sticky backed rubber or plastic patch approximately 3 mm thick to the swing gate inner panel where the switch contacts the door.

Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.
