Begin the system diagnosis with the Diagnostic System Check to 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 use of the Diagnostic System Check will identify the correct procedure for diagnosing the system and where the procedure is located. Refer to Diagnostic System Check - Vehicle in Computer/Integrating Systems.
