Power Liftgate Latch Homing

Following every cinch or release sequence, the power liftgate latch will return to a "home" or neutral position. If for some reason the latch is unable to return to the "home" position, the Power Liftgate Control Module (PLGM) will recognize this and prevent the latch from releasing. If this condition exists, activation of the power liftgate feature or exterior handle will result in a short beep from the power liftgate chime.

In this situation, perform the following:

1. Connect the diagnostic scan tool to the vehicle.
2. Select the PLGM from the "ECU List". perform the "Latch Home Position Test".
3. Select the "Misc Functions" menu.
4. Select and perform the "Latch Home Sector" routine. Follow the on-screen prompts to complete the procedure.
