Begin the IP or DIC system diagnosis with
Diagnostic System Check - Instrument Cluster
, or the audible warning
system diagnosis with
Diagnostic System Check - Audible Warnings
. 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.
