Circuit/System Testing

  1. Ignition OFF and all vehicle systems OFF, disconnect the harness at the appropriate B94 Side Object Sensor - Front. 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 3 and ground.
    • If 10 Ω or greater 
    1. Ignition OFF, disconnect the X3 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.
  4. Test for 7.8 - 10.2 V between the 8 V reference circuit terminal 1 and ground.
    • If less than 7.8 V 
    1. Ignition OFF, disconnect the X3 harness connector at the K86 Advanced Parking Assist Control Module.
    2. Test for infinite resistance between the 8 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 8 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 10.2 V 
    1. Ignition OFF, disconnect the X3 harness connector at the K86 Advanced Parking Assist Control Module.
    2. Test for less than 1 V between the 8 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 7.8 - 10.2 V 
  5. Test for 7 - 9 V between the signal circuit terminal 2 and ground.
    • If less than 7 V 
    1. Ignition OFF, disconnect the X3 harness connector at the K86 Advanced Parking Assist Control Module.
    2. 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
    3. Test for less than 2 Ω in the signal 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 9 V 
    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, replace the K86 Advanced Parking Assist Control Module.
    • If between 7 - 9 V 
  6. Test or replace the B94 Side Object Sensor - Front.
