Diagnostic Procedure: Notes

NOTE: Before proceeding with diagnosis, certain precautions must be followed. See PRETEST INSPECTION under SELF-DIAGNOSTIC SYSTEM.

Diagnostic procedures are designed to detect system faults as quickly as possible. Body control computer system diagnostic fault messages are accessed through Data Link Connector (DLC). See Figure . Chrysler's Diagnostic Readout Box (DRB) scan tool or generic scan tool, is used to access information from DLC.

A 1999 diagnostic program cartridge, scan tool, body diagnostics cable, jumper wires and digital volt/ohmmeter will be needed for testing. Proceed to IDENTIFYING VEHICLE EQUIPMENT & SYSTEM PROBLEMS under SYSTEM ID TEST in appropriate BODY CONTROL COMPUTER TESTS article.
