Vehicles equipped with a power liftgate (PLG) utilize a PLG control module. The power liftgate control module contains the electronic circuitry and software used to control the sequence of events for the power liftgate system. This module communicates on the Programmable communications Interface (PCI) bus circuit with the vehicles Body Control Module (BCM) to monitor many different inputs and outputs such as door lock status, transmission gear selector position and vehicle speed. The following schematic shows a typical Electrical Connections of a Power Liftgate Control Module.
