Module, Power Liftgate Control (PLGM): Description
Vehicles equipped with an optional power-operated liftgate are equipped with a Power LiftGate Module (PLGM). The PLGM is concealed behind the liftgate sill scuff plate and trim, on the inside of the back rear cargo area and covered with a water shield (1).
The PLGM is secured by two integral mounting tabs and an integral latch tab (2) to slots in the sheet metal. Two connector receptacles (2) integral to the PLGM housing are connected to the vehicle electrical system through two dedicated take outs and connectors of the body wire harness.
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 microcontroller and communicates with other electronic modules in the vehicle over the Controller Area Network (CAN) Interior High Speed (IHS) data bus system.
A PLGM cannot be adjusted or repaired and, if damaged or ineffective, it must be replaced. The PLGM software is flash programmable.
