BCM Functions

The Body Control Module (BCM) is capable of controlling multiple body functions. Components directly connected to the BCM are controlled by the BCM's outputs. The BCM controls the outputs based on input information that it obtains from the sensors and the switches that are directly connected to it. The BCM can also borrow information from other vehicle systems connected to the Class 2 serial data link. The BCM evaluates this information and controls certain body systems by commanding an output ON or OFF.

The BCM is also capable of commanding other vehicle systems to control functions that are not directly wired and/or controlled by the BCM. The BCM accomplishes this task by sending specific messages on the Class 2 serial data link. The vehicle system capable of performing such function will respond to the BCM message.
