Power Liftgate Control Module: Description
Vehicles equipped with a power liftgate (PLG) utilize a PLG control module. This module is located on the vehicles left side D-pillar just below the motor assembly (Fig 1) and contains a microprocessor, which is used to communicate to the vehicles body control module. The PLG control module receives and monitors logic inputs from all the PLG system switches except for the outside handle switch. This module also contains the software technology to detect lift gate obstructions and stop and/or reverse the door accordingly.
