6.7 Steering Angle Sensor (SAS) Service
Steering Angle Sensor (SAS) Calibration permanently stores the current steering wheel
position as the straight-ahead position in the SAS EEPROM. Therefore, the front wheels
and the steering wheel must be set exactly to the straight-ahead position before
calibration. In addition, the VIN is also read from the instrument cluster and stored
permanently in the SAS EEPROM. On successful completion of calibration, the SAS fault
memory is automatically cleared.
Calibration must always be carried out after the following operations:
 Steering wheel replacement
 SAS replacement
 Any maintenance that involves opening the connector hub from the SAS 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 SAS or assembly, or any part of the steering
system may have occurred
