Diagnostic Procedure: Introduction

Diagnostic test procedures are designed to detect system faults as quickly as possible. Body Diagnostic Trouble Codes (DTCs) 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 1995 diagnostic program cartridge, scan tool, body diagnostics cable, hand-held oil pressure gauge, jumper wires, and digital volt-ohmmeter will be needed for testing. Proceed to TEST 1A.

Ensure self-diagnostic tests apply to vehicle being tested. See BODY CONTROL COMPUTER TESTS DIRECTORY  table. When system problem is identified according to customer's complaint, perform diagnostic test(s) indicated.
