Circuit/System Testing

  1. Ignition OFF and all vehicle systems OFF, disconnect the harness connector at the appropriate B166 Advance Parking Assist Side Object Sensor. It may take up to 2 minutes for all vehicle systems to power down.
  2. Test for less than 10 Ω between the low reference circuit terminal 2 and ground.
    • If 10 Ω or greater 
    1. Ignition OFF, disconnect the harness connector at the K86 Advanced Parking Assist 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 K86 Advanced Parking Assist Control Module.
    • If less than 10 Ω 
  3. Ignition ON, engine running.
  4. Test for 11.5-13.5 V between the 12 V reference circuit terminal 1 and ground.
    • If less than 11.5 V 
    1. Ignition OFF, disconnect the harness connector at the K86 Advanced Parking Assist Control Module.
    2. Test for infinite resistance between the 12 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 12 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 K86 Advanced Parking Assist Control Module.
    • If greater than 13.5 V 
    1. Ignition OFF, disconnect the harness connector at the K86 Advanced Parking Assist Control Module, ignition ON.
    2. Test for less than 1 V between the 12 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 K86 Advanced Parking Assist Control Module.
    • If between 11.5-13.5 V 
  5. Ignition OFF, remove appropriate sensor and switch locations with another properly operating sensor. Connect harness connector at both sensors. Ignition ON.
  6. Verify the DTC is set for the new location in which the malfunctioning sensor is installed.
    • If DTC set for the new location 

      Replace the malfunctioning B166 Advanced Parking Assist Side Object Sensor.

    • If DTC set for the original location 
    1. Ignition OFF, disconnect the X3 harness connector at the K86 Advanced Parking Assist 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
    3. Ignition OFF.
    4. Test for infinite resistance between the signal circuit and ground.
      • If less than infinite resistance, repair the short to ground on the circuit.
      • If infinite resistance
    5. Test for less than 2 Ω in the circuit end to end.
      • If 2 Ω or greater, repair the open/high resistance in the circuit.
      • If less than 2 Ω, replace the K86 Advanced Parking Assist Control Module.
    • If no DTC set 
  7. All OK.
