The steering angle sensor must be calibrated after:

1. A new steering angle sensor has been installed,
2. The PSM control device has been exchanged,
3. The steering gear and / or components which change the zero position of the steering angle sensor have been exchanged,
4. Accident repairs,
5. Suspension alignment procedures during which the previous wheel alignment values were changed.

Check the steering angle sensor actual value in the following cases: 

1. Suspension alignment when no change has been made to the wheel alignment values.
2. As a check after steering angle sensor calibration.
