Some 2007 full-size utilities are equipped with a power-operated liftgate, which opens and closes with the push of a button. The system is controlled by the Power Liftgate Module (PLGM).
If you need to reprogram an existing PLGM, or program a replacement, you must perform the following procedure to avoid leaving a current B1019 trouble code which cannot be cleared until the PLGM is "learned."
After completing the programming event, perform the liftgate calibration procedure with Tech 2.
TIP:Â To ensure proper calibration of the liftgate, the liftgate assembly must be at room temperature during calibration.
- Close the vehicle liftgate. Failure to do so will result in a failed liftgate calibration.
- Connect the Tech 2 to the vehicle.
- Select Special Functions in the Liftgate Module menu.
- Select LGM Open/Close Test.
- Follow the on-screen instructions.
TIP:Â When the liftgate is under control of the Tech 2, the liftgate will be driven to the full open position. An audible sound at this point is normal.
Only after following these steps, use your Tech 2 to clear the B1019 code.
