Diagnostic Procedure

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

Diagnostic test 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 1997 diagnostic program cartridge, scan tool, body diagnostics cable, jumper wires, and digital volt/ohmmeter will be needed for testing. Proceed to SYMPTOM ID TEST 1A - IDENTIFYING VEHICLE EQUIPMENT & SYSTEM PROBLEMS in BODY CONTROL COMPUTER TESTS .
