Control Module: Testing and Inspection
AWD CONTROL MODULE INSPECTION
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.
1. Measure voltage or resistance at each AWD CM terminal using a voltmeter and an ohmmeter.
- If not as specified, replace the AWD CM.
