Circuit/System Testing

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2018 GMC Yukon XL, 2018 GMC Yukon, 2018 Chevrolet Tahoe, 2018 Chevrolet Suburban, and 2018 Cadillac Escalade ESV. However, it is still accessible from the selected car via links, so may be relevant.
  1. Ignition ON.
  2. Verify that DTC C0710 4B or C0710 5A is not set.
    • Go to next step: If DTC C0710 4B or C0710 5A is not set 
  3. 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 
  4. Ignition OFF and all vehicle systems OFF, disconnect the harness connector at the B99 Steering Wheel Angle Sensor. It may take up to 2 min for all vehicle systems to power down.
  5. Test for less than 5 Ω between the ground circuit terminal 6 and ground.
    • If 5 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 5 Ω 
  6. Ignition ON.
  7. 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 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 
  8. Replace the B99 Steering Wheel Angle Sensor.
  9. Ignition ON.
  10. 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 
  11. All OK.
