The body control system consists of the body control module (BCM) and its associated controls. Battery positive voltage is provided to the BCM from the TURN/HAZ fuse and the CHMSL/BKUP fuse in the fuse block I/P. The module grounds are wired to ground G200, G201 and G301. The BCM is wired to the class 2 serial data communication bus as well as discrete input and output terminals to control the functions of the vehicles body .
Power Mode Master
This vehicles BCM functions as the Power Mode Master (PMM). Refer to Power Mode Description and Operation for a complete description of power mode functions.
