Body Control Computer: Description
The body control computer system consists of a combination of modules that communicate over the Chrysler Collision Detection (CCD) 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 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)
- Power door locks
- Power windows
- Remote keyless entry
- Smart key immobilizer system
- 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.
