Expected Result:

The resistance is less than 5 ohms for all of the measurements.

Results:

  • Ok - The resistance is less than 5 ohms for all of the measurements. Proceed to Test Step 4.

  • NOT OK - Resistance is greater than 5000 ohms for one or more of the measurements.

    Repair: The harness has failed. Repair the harness or replace the harness.

    STOP

Test Step 4. CHECK THE ECM.

  1. Reconnect all of the connectors to the AWD ECM.

  1. Turn the disconnect switch to the ON position.

  1. Turn the key start switch to the ON position.

  1. The harness remains disconnected from the switch.

  1. At the harness connector for the switch, measure the voltage between the following:

    • Contact 1 (wire A201-BK) and contact 2 (wire F747-OR)

    • Contact 1 (wire A201-BK) and contact 3 (wire 823-GN)

    • Contact 1 (wire A201-BK) and contact 4 (wire 718-BU)

Expected Result:

The voltage measures approximately 12.0 ± 0.5 DCV.

Results:

  • OK - The voltage measures approximately 12.0 ± 0.5 DCV. Proceed to Test Step 5.

  • NOT OK - The voltage is not approximately 12.0 ± 0.5 DCV.

    Repair: The voltage from the ECM is incorrect. It is unlikely that the ECM has failed. Exit this procedure and perform this troubleshooting procedure again.
