Circuit/System Testing

  1. Ignition ON.
  2. Verify that DTC U0125 or U0126 is not set.
    • Go to next step: If none of the DTCs are not set 
  3. Verify that DTC C0710 42 is not set.
    • Go to next step: If the DTC is not set 
  4. Verify the B99 Steering Wheel Angle Sensor is installed correctly.
    • If loose or incorrect installation 

      Correct the installation or replace the component.

    • Go to next step: If correct installation 
  5. Ignition OFF and all vehicle systems OFF with the scan tool disconnected, disconnect the harness connector at the B99 Steering Wheel Angle Sensor. It may take up to 2 minutes for all vehicle systems to power down.
  6. Test for less than 10 Ω between the ground circuit terminal 6 and ground.
    • If 10 Ω or greater 
    1. Ignition OFF.
    2. Test for less than 2 Ω in the ground circuit end to end.
      • If 2 Ω or greater, repair the open/high resistance in the circuit.
      • If less than 2 Ω, repair the open/high resistance in the ground connection.
    • Go to next step: If less than 10 Ω 
  7. Ignition ON.
  8. Verify a test lamp illuminates between the ignition circuit terminal 5 and ground.
    • If the test lamp does not illuminate 
    1. Ignition OFF, disconnect the harness connector at the K17 Electronic Brake Control Module.
    2. Test for infinite resistance between the ignition circuit and ground.
      • If less than infinite resistance, repair the short to ground on the circuit.
      • Go to next step: If infinite resistance
    3. Test tor less than 2 Ω in the ignition circuit end to end.
      • If 2 Ω or greater, repair the open/high resistance in the circuit.
      • If less than 2 Ω, replace the K17 Electronic Brake Control Module.
    • Go to next step: If the test lamp illuminates 
  9. Replace the B99 Steering Wheel Angle Sensor.
  10. Ignition ON.
  11. Verify that DTC C0710 is not set.
    • Go to next step: If the DTC is not set 
  12. Verify the DTC does not set while operating the vehicle within the Conditions for Running the DTC.
    • If the DTC sets 

      Replace the K17 Electronic Brake Control Module.

    • Go to next step: If the DTC does not set 
  13. All OK.
