Initial Inspection and Diagnostic Overview

DIAGNOSTIC STARTING POINT

Begin the instrument panel (I/P) system diagnosis with the appropriate Vehicle Diagnostic System Check: 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.
