Description And Operation: Description
Vehicles equipped with a power liftgate system utilize a Power LiftGate control Module (PLGM) (1) with an integrated chime. This module is located on the right side of the vehicle behind the quarter trim panel and below the quarter glass. The power liftgate control module receives and monitors logic inputs from all the power liftgate system switches. This module also contains the software technology to detect liftgate obstructions and stop or reverse the door accordingly.
Concealed and protected within the molded plastic housing of the PLGM (1) is the printed circuit board and the other electronic circuitry of the module. The module contains a micro controller 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 (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.
