OVERVIEW:
This bulletin involves flashing the Power Lift Gate (PLG) module and resetting obstacle detection values. Adjusting the lift gate striker and/or installing lift gate overslam bumper shims may also be required.
MODELS:
SYMPTOM/CONDITION:
The PLG functions in the power closing mode but not the opening mode. The lift gate is not flush with the tail lights. Low seal load prevents the lift gate from "popping off" and moving the lift gate latch out of the primary latching position.
DIAGNOSIS:
DIAGNOSIS 1:
Power operate the lift gate to open with the Remote Keyless Entry (RKE) Fob or button in the overhead console. If the lift gate does not move out of the primary latching position, perform Repair Procedure 1.
DIAGNOSIS 2:
Inspect the lift gate for flushness to the body above and below the tail lamps. If the lift gate is underflush to the body above the tail lamp and underflush or flush below the tail lamp, go to Procedure 2A. If the lift gate is flush or overflush to the body above and below the tail lamp, go to Procedure 2B. If the lift gate is flush or underflush to the body above the tail lamps and over flush below the tail lamp AND the difference is more than 5 mm, go to Procedure 2C.
