Diagnostic Starting Point

Begin the system diagnosis with the Diagnostic System Check - Accessory Delay Module. The Diagnostic System Check will provide the following information:
^ The identification of the control module which commands the system
^ The ability of the control module 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 will identify the correct procedure for diagnosing the system and where the procedure is located.
