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, Figure or 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.
