Section 91 (Body Control Computer): Description
WARNING: This page is about a different car, the 1998 Dodge Intrepid and 1998 Chrysler Concorde. However, it is still accessible from the selected car via links, so may be relevant.
The body control computer system consists of a combination of modules that communicate over the Programmable Communication Interface (PCI) bus system. Through the 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 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.
