Begin the system diagnosis with the
Diagnostic System Check - Vehicle
in Vehicle
DTC Information. 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.
