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.

Immobilizer System
The immobilizer system allows the engine to start only with a key the system
recognizes.
If someone attempts to start the engine with an unrecognized key, the engine
will not start, thereby helping to prevent the theft of your vehicle.
If you have a problem with the immobilizer system or the k ...
