REPROGRAMMING THE POWER LIFTGATE MODULE

1. Verify that the scan tool (WDS Or VCM) is updated to software version B42.1 P1 or later.

2. Reprogram the power liftgate (PLG) module to the latest software version using one of the following methods:

a) Worldwide Diagnostic System (WDS).

b) Vehicle Communication Module (VCM) and Integrated Diagnostic System (IDS) software with appropriate hardware.

^ If unable to reprogram the PLG module:

- prior to disconnecting the scan tool and closing the session, call the Special Service Support Center for further instructions.

3. Power open the liftgate by using either the key fob or the overhead console switch.

^ If the liftgate remains open, power close the liftgate using either the key fob or overhead console switch. Service is complete. Release the vehicle.

^ Once open, if the liftgate freely falls or goes into "power close" mode (accompanied by an audible alert that sounds four [4] times per second) without activating either the key fob or overhead switch, contact the Special Service Support Center for further instruction.
