Diagnosis & Testing
Begin the system diagnosis with a Diagnostic System Check-Vehicle. The Diagnostic System Check 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 will identify the correct procedure for diagnosing the system and where the procedure is located.
