The SAS Function of Autel MaxiDiag MD808 PRO

Steering Angle Sensor Calibration permanently stores the current steering wheel position as the straight-ahead position in the steering angle sensor EEPROM. Therefore, the front wheels and the steering wheel must be set exactly to the straight-ahead position before calibration. In addition, the vehicle identification number is also read from the instrument cluster and stored permanently in the steering angle sensor EEPROM. On successful completion of calibration, the steering angle sensor fault memory is automatically cleared.

* Any maintenance or repair work on the steering linkage, steering gear or other related mechanism
* Wheel alignment or wheel track adjustment
* Accident repairs where damage  to the steering angle sensor or assembly, or any part of the steering system may have occurred
