AWD CONTROL MODULE INSPECTION



If not as specified, replace the AWD CM.  

TERMINAL VOLTAGE LIST (REFERENCE) 

NOTE:



AWD CM terminal voltage can vary depending on measuring conditions 
and vehicle aging, resulting in misdiagnosis. Therefore, it is necessary to 
perform an overall inspection of the input/output systems and AWD CM to 
determine which part is malfunctioning.  



With the AWD CM connector connected, measure voltage by connecting 
the voltmeter negative (-) lead to the body ground and positive (+) lead to 
each AWD CM terminal.
