Circuit/System Testing

WARNING: This page is about a different car, the 2017 Chevrolet Spark. However, it is still accessible from the selected car via links, so may be relevant.
  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.
