Section 102 (Engine Controls - Tests W/Codes - Body Control Computer): Introduction: Description

WARNING: This page is about a different car, the 1994 Plymouth Voyager, 1994 Plymouth Grand Voyager, 1994 Dodge Grand Caravan, 1994 Dodge Caravan, and 1994 Chrysler Town & Country. However, it is still accessible from the selected car via links, so may be relevant.

The body control computer system, also referred to as the Body Control Module (BCM) system, consists of a combination of modules that communicate over the Chrysler Collision Detection (CCD) BUS system. Through the CCD BUS, information related to the operation of vehicle components and circuits is relayed to the appropriate system module(s). Each module receives the same component information. This reduces the complexity of vehicle wiring and size of wiring harness.

The following BCM systems are covered in this article: electronic instrument cluster, electro/mechanical instrument cluster, compass/mini-trip module, power door locks, Remote Keyless Entry (RKE), side door memory lock, windshield wiper, illuminated entry, courtesy lights, key-in light system, headlight time delay, liftgate release, seat belt warning light system and chimes. System failures within these systems can be diagnosed via the CCD BUS Data Link Connector (DLC) using Chrysler Diagnostic Readout Box (DRB) tester.
