Body Control Modules: 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 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.

Diagnostic Trouble Codes (DTCs) are accessed through a 16-pin Data Link Connector (DLC) using Chrysler's Diagnostic Readout Box (DRBIII(R)) scan tool or generic scan tool. DLC is located under driver's side of instrument panel, right of steering column.
