10. SAS (Steering Angle Sensor) Calibration
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.
Calibration must always be carried out after the following
operations:

Steering wheel replacement

Steering angle sensor replacement

Any maintenance that involves opening the connector hub from
the steering angle sensor to the column

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
NOTE: AUTEL accepts no responsibility for any accident or
injury arising from servicing the SAS system. When
interpreting DTCs retrieved from the vehicle, always follow
the manufacturer’s recommendation for repair.
