Diagnostic Procedure: Introduction

Diagnostic test procedures are designed to detect system faults as quickly as possible. Body trouble codes are accessed through Data Link Connector (DLC). See Figure . Chrysler's Diagnostic Readout Box (DRB) is used to access information from DLC.

A 1994 diagnostic program cartridge, DRB, body diagnostics cable, hand-held oil pressure gauge, jumper wires, and digital volt-ohmmeter will be needed for testing. Proceed to TEST 1A in BODY CONTROL COMPUTER TESTS.

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 indicated.
