Description & Operation: Notes

The body control computer system consists of a combination of modules that communicate over Collision Detection (CCD) bus system. Through the CCD 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 are as follows: Chime system, compass/mini-trip computer, door ajar system, exterior lighting, interior lighting, intermittent wipers, instrument cluster, memory seats, power door locks, power mirrors, power windows, remote keyless entry, vehicle information center and vehicle theft security system.

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. See Fig 1 .
