Body Control System Description and Operation: Notes

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 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.
