Circuit/System Testing

NOTE:

Circuit/System Verification must be performed before Circuit/System Testing.

  1. Ignition OFF, disconnect the harness connector at the B87 Rearview Camera.
  2. Test for less than 10 ohms between the ground circuit terminal 5 and ground.
    • If 10 ohms or greater 

      Test for less than 2 ohms in the ground circuit end to end.

    • If 2 ohms or greater, repair the open/high resistance in the circuit.
    • If less than 2 ohms, repair the open/high resistance in the ground connection.
    • If less than 10 ohms 
  3. Ignition ON.
  4. Verify a test lamp illuminates between the ignition circuit terminal 6 and ground.
    • If the test lamp does not illuminate and the circuit fuse is good 
    1. Ignition OFF.
    2. Test for less than 2 ohms in the ignition circuit end to end.
      • If 2 ohms or greater, repair the open/high resistance in the circuit.
      • If less than 2 ohms, verify the fuse is OK and there is voltage at the fuse.
    • If the test lamp does not illuminate and the circuit fuse is open 
    1. Ignition OFF.
    2. Test for infinite resistance between the ignition circuit and ground.
      • If less than infinite resistance, repair the short to ground on the circuit.
      • If infinite resistance, test or replace the KR74 Ignition Run Relay.
    • If the test lamp illuminates 
  5. Engine running, park brake applied, transmission in REVERSE.
  6. Test for greater than 11V between the control circuit terminal 3 and ground.
    • If less than 11V 
    1. Ignition OFF, disconnect the X7 harness connector at the K9 Body Control Module.
    2. Test for infinite resistance between the control circuit and ground.
      • If less than infinite resistance, repair the short to ground on the circuit.
      • If infinite resistance
    3. Test for less than 2 ohms in the control circuit end to end.
      • If 2 ohms or greater, repair the open/high resistance in the circuit.
      • If less than 2 ohms, replace the K9 Body Control Module.
    • If greater than 11V 
  7. Ignition OFF, disconnect the X4 harness connector at the A11 Radio, ignition ON.
  8. Test for less than 1V between the signal circuit terminal listed below and ground:
    • Signal (+) circuit terminal 1 at the B87 Rearview Camera.
    • Signal (-) circuit terminal 4 at the B87 Rearview Camera.
    • If 1V or greater 

      Repair the short to voltage on the circuit.

    • If less than 1V 
  9. Test for infinite resistance between the signal circuit terminal listed below and ground:
    • Signal (+) circuit terminal 1 at the B87 Rearview Camera.
    • Signal (-) circuit terminal 4 at the B87 Rearview Camera.
    • If less than infinite resistance 

      Repair the short to ground on the circuit.

    • If infinite resistance 
  10. Test for less than 2 ohms in the signal (+) circuit end to end.
    • If 2 ohms or greater 

      Repair the open/high resistance in the circuit.

    • If less than 2 ohms 
  11. Test for less than 2 ohms in the signal (-) circuit end to end.
    • If 2 ohms or greater 

      Test the signal circuit for an open/high resistance.

    • If less than 2 ohms 
  12. Replace the B87 Rearview Camera.
  13. Engine running, transmission in REVERSE, verify a clear rear vision image is displayed on the A11 Radio.
    • If a clear rear vision image is not displayed on the A11 Radio 

      Replace the A11 Radio.

    • If a clear rear vision image displayed on the A11 Radio 
  14. All Ok.
