Module, Power Liftgate Control: Description: Description
Vehicles equipped with an optional power-operated liftgate are equipped with a Power LiftGate Module (PLGM) (2) (also known as the Power LiftGate/PLG control module). The PLGM is concealed behind the trim on the inside of the left D-pillar below the belt line, where it is secured by two integral mounting tabs (4) and an integral latch tab (1) to slots in the inner D-pillar sheet metal.
Concealed and protected within the molded plastic housing of the PLGM is the printed circuit board and the other electronic circuitry of the module. The module contains a microprocessor and communicates with other electronic modules in the vehicle over the Controller Area Network (CAN) Interior High Speed (IHS) data bus system. Two connector receptacles (3) integral to the PLGM housing are connected to the vehicle electrical system through two dedicated take outs and connectors of the body wire harness.
A PLGM cannot be adjusted or repaired and, if damaged or ineffective, it must be replaced. The PLGM software is flash programmable.
