Body Control Module: Description and Operation
BCM Functions
The Body Control Module (BCM) is capable of accomplishing multiple body control functions. Components directly connected to the BCM and
controlled by the BCM's outputs. The BCM can control its outputs based on input information it obtains from sensors and switches that are directly
connected to the BCM, or by borrowing information from other vehicle systems connected to the Class II 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 II serial data link. The vehicle system capable of performing such function will respond
to the BCM message.
The BCM performs these functions:
^
Audible warnings.
^
Interior lighting.
^
Automatic door locks.
^
Keyless entry.
^
Passlock theft deterrent.
