Circuit/System Testing

WARNING: This page is about a different car, the 2019 Buick Cascada, 2018 Buick Cascada, and 2017 Buick Cascada. However, it is still accessible from the selected car via links, so may be relevant.
  1. Ignition ON.
  2. Verify that DTC U0073, U0074, U0125 or U0126 is not set.
    • Go to next step: If none of the DTCs are set 
  3. Verify that DTC C0710 42 or C0710 5A is not set.
    • Go to next step: If DTC C0710 42 or C0710 5A is not set 
  4. Verify the B99 Steering Wheel Angle Sensor is installed correctly.
    • If loose or incorrect installation

  5. Ignition OFF and all vehicle systems OFF, 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 12 V reference 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 12 V reference 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 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 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.
    • If DTC C0710 is set 

      Replace the K17 Electronic Brake Control Module.

    • Go to next step: If DTC C0710 is not set 
  12. Verify that DTC C0460 is not set.
    • If DTC C0460 is set 

      Replace the K19 Suspension Control Module.

    • Go to next step: If DTC C0460 is not set
