Body Control Module

The Body Control Module (BCM) supplies vehicle occupants with visual and audible information and controls various vehicle functions. To provide and receive information, the module is interfaced to the vehicle's serial bus communications network (the Chrysler Collision Detection bus, or CCD bus). This network consists of the Powertrain Control Module (PCM), the Transmission Control Module (TCM), the electro/Mechanical Instrument Cluster (MIC), the optional Overhead Travel Information System (OTIS), Airbag Control Module (ACM), and the optional Automatic Temperature Control (ATC) display head. The BCM is operational when battery power is supplied to the module. Ignition switch power is needed for ignition switched functions.
