Hi Radovan. Make sure that: 1. The road wheels are facing straight forward 2. The steering wheel is properly centered. 3. Connect the Tech 2 scan tool (or alternately capable tool) 4. In "Special Functions", select "Steering Position Sensor Calibration" and follow the scan tool prompts. This is located in GM Service Information system, listed under "Steering Wheel Angle Sensor Centering."…

Does the steering angle pid change at all when rotating steering wheel? Usually when the calibration is off you will have some assist in one direction, but not the other. The module (not sensor) probably was damaged with the reverse jumping. Same with rollover issue. Confirm wiring to modules and sensors before replacing.
