    1. Turn the ignition off.
    2. Inspect the CVPM harness connector for a secure and undamaged connection.
    3. Inspect the Coax Cable in-line harness connectors for a secure and undamaged connection.
    4. Inspect the related Camera harness connector for a secure and undamaged connection.

      Are the connections secure and undamaged?

      Yes 

      • Go To  11

      No 

      • Repair the cable connection as needed and check video operation.
      • Perform the BODY VERIFICATION TEST. Refer to BODY VERIFICATION TEST .
  11. CHECK THE CVPM 
    NOTE:

    The following test is being used to determine that the CVPM recognizes a known good camera, cable and the related connections.

    Central Vision Processing Module (CVPM) Connector Color Coding
    Front Camera Green
    Left Camera Beige
    Right Camera Brown
    Rear Camera Orange
    Video Output to Radio / Display Violet
    1. On the vehicle, identify and locate the faulted circuit connector for testing at the CVPM.
      NOTE:

      For example, a fault setting for the Front Camera would indicate the GREEN connector at the CVPM.

    2. Disconnect the connector at the CVPM for the faulted circuit being set against.
    3. On the vehicle, identify and locate a known good operating and functioning camera, circuit and related connector at the CVPM.
    4. Disconnect the connector at the CVPM for a known good operating and functioning camera.
      NOTE:

      Continuing with the example, if a fault was setting against the Front Camera; and the Rear Camera is operating and functioning normally on the vehicle - disconnect the Rear Camera connector (ORANGE connector) at the CVPM to further test with.

    5. From the special tool (#9977-6-8, Adapter, RG-174 Coax Cable) kit, connect the 9977-6-8-2 test lead to the 9977-6-8-3 test lead.
    6. Connect the other end of the 9977-6-8-2 test lead to the CVPM connection for the fault related camera circuit.
      NOTE:

      In the example, the BLUE connector from the 9977-6-8-2 test lead would connect to the GREEN connector on the CVPM. We are using a known good camera, cable, and connection from the Rear Camera as a substitute for the questionable camera, cable, and connection on the Front Camera.

    7. Connect the other end of the 9977-6-8-3 test lead to the coaxial cable going to the known good operating and functioning camera.
      NOTE:

      In the example, the BLUE connector from the 9977-6-8-3 test lead would connect to the ORANGE connector going to the Rear Camera. We are using a known good camera, cable, and connection from the Rear Camera as a substitute for the questionable camera, cable, and connection on the Front Camera.

    8. Check the activity status of the camera and fault status.
      NOTE:

      In the example, the status of the Front Camera should show an active image (possibly inverted - due to orientation) of the known good camera circuit being used. The related DTCs for the Front Camera should change to STORED. In this example the CVPM would then show no active image and would show ACTIVE DTCs set against the Rear Camera with no connection being present.

      Did camera activity return and the status of the original setting DTC(s) change to Stored?

      Yes 

      • A known good camera, cable, and connection was used for testing and the CVPM is no longer a possible cause. The camera and cable are the remaining possible causes.
      • Go To  12

      No 

      • A known good camera, cable, and connection was used for testing and the CVPM is the only remaining cause.
      • Go To  13
  12. TEST THE COAX CABLE BETWEEN THE CVPM AND RELATED CAMERA 
    1. Turn the ignition off.
    2. Disconnect the 9977-6-8-2 and the 9977-6-8-3 test leads from the vehicle.
    3. Reconnect the known connector for the known good operating and functioning camera circuit used for testing previously.
      NOTE:

      In the example, the Rear Camera connector (ORANGE connector) was disconnected at the CVPM for testing purposes.

    4. From the special tool (#9977-6-8, Adapter, RG-174 Coax Cable) kit, connect the long cable (9977-6-8-1) between the related Camera and the CVPM connector.
    5. Turn the ignition on.
    6. With the scan tool, erase DTCs.
    7. Turn the Radio on and wait 25 seconds.
    8. With the scan tool, read DTCs.

      Is the DTC active?

      Yes 

      No
