In addition, the vehicle identification number is also read from the instrument cluster and stored permanently in the steering angle sensor. Calibration must always be carried out after the following operations:
What should I do after replacing the steering angle sensor?
After replacing the steering-angle sensor, it must first be coded and then calibrated. In order to perform its internal calculations, the steering angle sensor requires model-specific data which has to be loaded onto it by means of coding.
