    Turn the ignition off.

    Disconnect the Instrument Cluster harness connector.

    Measure the voltage between the (A908) Fused B(+) circuit and ground.

    Is the voltage above 10.5 volts? 

    Yes 

    1. Go To step  2).

    No 

    1. Repair the (A908) Fused B(+) circuit for an open.
    2. Perform BODY VERIFICATION TEST .
  2. 2) (G150) INSTRUMENT CLUSTER WAKE UP SIGNAL CIRCUIT OPEN

    Turn the ignition off.

    Disconnect the Instrument Cluster harness connector.

    Disconnect the BCM C1 harness connector.

    Measure the resistance of the (G150) Instrument Cluster Wake Up Signal circuit.

    Is the resistance above 5.0 ohms? 

    Yes 

    1. Repair the (G150) Instrument Cluster Wake Up Signal circuit for an open.
    2. Perform BODY VERIFICATION TEST .

    No 

    1. Go To step  3).
  3. 3) (G150) CLUSTER WAKE UP CIRCUIT SHORT TO GROUND

    Turn the ignition off.

    Disconnect the Instrument Cluster harness connector.

    Disconnect the BCM C1 harness connector.

    Measure the resistance between ground and the (G150) Cluster Wake Up circuit.

    Is the resistance below 5.0 ohms? 

    Yes 

    1. Repair the (G150) Instrument Cluster Wake Up Signal circuit for a short to ground.
    2. Perform BODY VERIFICATION TEST .

    No 

    1. Go To step  4).
  4. 4) BODY CONTROL MODULE

    Turn the ignition off.

    Disconnect the Instrument Cluster harness connector.

    Ensure that the BCM C1 harness connector is connected.

    Install a DVOM between the Cluster Wake Up circuit of the Instrument Cluster harness connector and ground.

    Set the DVOM to read resistance.

    Turn the ignition on.

    With the scan tool, select Body Control Module, then Actuators.

    Observe the DVOM while using the scan tool to actuate the Cluster Wake Up "on."

    Did the DVOM indicate a brief (2 second) continuity to ground? 

    Yes 

    1. Go To step  5).

    No 

    1. Replace and program the Body Control Module in accordance with the Service Information.
    2. Perform BODY VERIFICATION TEST .
  5. 5) INSTRUMENT CLUSTER 

    Turn the ignition off.

    Ensure that the Instrument Cluster and BCM C1 harness connectors are connected.

    Open the driver door or actuate the High Beam Headlamps with the key off.

    With the scan tool, read DTCs.

    Did this DTC reset? 

    Yes 

    1. Replace and configure the Instrument Cluster in accordance with the Service Information.
    2. Perform BODY VERIFICATION TEST .

    No 

    1. The condition is not present at this time. Monitor scan tool DTCs while wiggling the related wire harness. Refer to any Technical Service Bulletins (TSB) that may apply. Visually inspect the related wiring harness and connector terminals.
    2. Perform BODY VERIFICATION TEST .
