Body Control Computer

The body control computer, also called Body Control Module (BCM), is located behind right side kick panel. BCM stores odometer information for electronic instrument cluster display and provides power and ground for a variety of systems.

BCM is the only module that has the capability of providing both "bias" and "termination" on the CCD bus system. See CCD BUS SYSTEM. Systems are monitored by BCM through voltage drops.

Vehicle may be equipped with either a premium or base model BCM. Base body control computer is used on vehicles with a mechanical instrument cluster and no EVIC.

Premium BCM can be identified by the presence of either the Automatic Temperature Control (ATC) system, Overhead Travel Information System (OTIS), or both.
