DIAGNOSTIC STARTING POINT - ENGINE ELECTRICAL
Begin the system diagnosis with Diagnostic System Check - Vehicle . The Diagnostic System
Check - Vehicle will provide the following information:
The identification of the control modules which command the system
The ability of the control modules to communicate through the serial data circuit
The identification of any stored diagnostic trouble codes (DTCs) and their status
The use of the Diagnostic System Check - Vehicle will identify the correct procedure for
diagnosing the system and where the procedure is located.
