Begin system diagnosis with Diagnostic System Check - Door Systems . The Diagnostic System Check will provide the following information:
| • | Identification of the control module(s) that command the system |
| • | The ability of the control module(s) to communicate through the serial data circuit |
| • | Identification of 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.
The Diagnostic System Check will link to Symptoms when communication can be established and no DTCs are present.
