Body Control Computer - Introduction: Description

The body control computer system consists of a combination of modules that communicate over the Chrysler Collision Detection (CCD) bus system on all models except Concorde and Intrepid. Concorde and Intrepid communicate over the Programmable Communication Interface (PCI) bus system. Through the CCD or PCI bus, information related to the operation of vehicle components and circuits are relayed to the appropriate system module(s). This reduces the complexity of vehicle wiring and size of wiring harness.

Body control computer systems covered in BODY CONTROL COMPUTER TESTS article are as follows:

Chime system
Compass/Mini-Trip Computer (CMTC)
Door ajar system
Exterior lighting
Instrument cluster
Interior lighting
Intermittent wipers
Mechanical Instrument Cluster (MIC)
Memory Heated Seat/Mirror System (MHSMS)
Power door locks
Power windows
Remote keyless entry
Sentry Key Immobilizer System (SKIS)
Vehicle Information System (VIC)
Vehicle Theft Security System (VTSS).

Body control computer fault messages are accessed through 16-pin Data Link Connector (DLC) using Chrysler's Diagnostic Readout Box (DRB) scan tool or generic scan tool. DLC is located on left side of steering column, above brake pedal.

NOTE: Self-diagnostic tests are written specifically for Chrysler's Diagnostic Readout Box (DRB) scan tool. A generic scan tool may not be capable of performing all necessary test functions.
