Begin the system diagnosis with the
Diagnostic System Check - Transfer Case
. The Diagnostic System
Check will provide the following information:
• | The identification of the control module which 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.
