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

A 1993 diagnostic program cartridge, DRB-II, body diagnostics cable, hand-held oil pressure gauge, jumper wires, and digital volt/ohmmeter will be needed for testing. Proceed to TEST 1A: IDENTIFYING VEHICLE EQUIPMENT & SYSTEM PROBLEMS (IDENTIFYING VEHICLE EQUIPMENT & CCD BUS COMMUNICATION PROBLEMS on AC and AY bodies).

Ensure self-diagnostic tests apply to vehicle being tested. When system problem is identified according to customer's complaint, perform diagnostic test indicated.
