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
