Begin the system diagnosis with the Diagnostic System Check
- Retained Accessory Power. The Diagnostic System Check will provide
the following information:
• | The identification of the control module that 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.
