  • You should start by performing a Steering Position Sensor calibration. You must use a scanner capable of calibrations, some alignment shops have the tools to calibrate the sensor.

    1. Clear all the codes.
    2. Perform the "Steering Pos./Torque Sensor Cal" in the power steering control module. During the calibration procedure steering assist will not function. Raising the vehicle off the ground will reduce the steering loads and make it easier to perform the procedure.
    3. Perform the "Steering Pos. Sensor Calibration" in the electronic brake control module.
    4. Verify that there are no DTCs.
    5. Test drive the vehicle.
