Steering Angle Sensor (SAS) Service

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

1. 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.
