Circuit/System Testing

  1. Ignition OFF, disconnect the B225R Sideview Camera - Right harness connector. It may take up to 2 min for all vehicle systems to power down.
  2. Test for less than 10 Ω between the low reference circuit terminal 5 and ground.
    • If 10 Ω or greater 
    1. Ignition OFF, disconnect the harness connector at the K157 Video Processing Control Module.
    2. Test for less than 2 Ω in the low reference circuit end to end.
      • If 2 Ω or greater, repair the open/high resistance in the circuit.
      • If less than 2 Ω, replace the K157 Video Processing Control Module.
    • If less than 10 Ω 
  3. Ignition ON.
  4. Test for 4.8-7.2 V between the 6 V reference circuit terminal 6 and ground.
    • If less than 4.8 V 
    1. Ignition OFF, disconnect the harness connector at the K157 Video Processing Control Module.
    2. Test for infinite resistance between the 6 V reference 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 Ω in the 6 V reference circuit end to end.
      • If 2 Ω or greater, repair the open/high resistance in the circuit.
      • If less than 2 Ω, replace the K157 Video Processing Control Module.
    • If greater than 7.2 V 
    1. Ignition OFF, disconnect the harness connector at the K157 Video Processing Control Module, ignition ON.
    2. Test for less than 1 V between the 6 V reference circuit and ground.
      • If 1 V or greater, repair the short to voltage on the circuit.
      • If less than 1 V, replace the K157 Video Processing Control Module.
    • If between 4.8-7.2 V 
  5. Ignition ON.
  6. Test for less than 10 V between the signal circuit terminals listed below and ground:
    • Vision Signal + signal circuit terminal 1
    • Vision Signal - signal circuit terminal 4
    • If 10 V or greater 
    1. Ignition OFF, disconnect the X1 harness connector at the K157 Video Processing Control Module, ignition ON.
    2. Test for less than 1 V between the signal circuit and ground.
      • If 1 V or greater, repair the short to voltage on the circuit.
      • If less than 1 V, replace the K157 Video Processing Control Module.
    • If less than 10 V 
  7. Ignition OFF.
  8. Test for greater than 100 Ω between the signal circuit terminals listed below and ground:
    • Vision Signal + signal circuit terminal 1
    • Vision Signal - signal circuit terminal 4
    • If less than 100 Ω 
    1. Disconnect the X1 harness connector at the K157 Video Processing Control Module.
    2. Test for infinite between the signal circuit and ground.
      • If less than infinite resistance, repair the short to voltage on the circuit.
      • If infinite resistance, replace the K157 Video Processing Control Module.
    • If greater than 100 Ω 
  9. Test for less than 2 Ω between the video signal circuit terminals listed below:
    • B225R Sideview Camera - Right video signal (+) circuit terminal 1 and the K157 Video Processing Control Module video signal (+) circuit terminal 8 X1
    • B225R Sideview Camera - Right video signal (+) circuit terminal 4 and the K157 Video Processing Control Module video signal (+) circuit terminal 18 X1
    • If 2 Ω or greater 

      Repair the open/high resistance in the circuit.

    • If less than 2 Ω 
  10. Ignition OFF, connect the harness connector at the B225R Sideview Camera - Right.
  11. Ignition ON, clear DTCs. Operate the vehicle within the Conditions for Running the DTC.
  12. Verify DTC B395C is not set.
    • If DTC B395C is set 

      Replace the B225R Sideview Camera - Right.

    • If DTC B395C is not set 
  13. All OK.
