Mazda CX-5 Service & Repair Manual: 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.
