5.3 SAS
Steering Angle Sensors (SAS) System 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 codes will be automatically cleared.
To reset the steering angle, you need to first find the relative
zero point position for the car to drive in a straight line. Taking
this position as a reference, the ECU can calculate the accurate
angle for left and right steering.
After replacing the steering angle position sensor, replacing
steering mechanical parts (such as steering gearbox, steering
column, end tie rod, steering knuckle), performing four-wheel
alignment, or recovering the car body, you must reset the
steering angle.
The operation guidelines of the SAS function are shown as
below:
1. Enter the SAS menu and choose relevant models
according to the vehicle being tested.
2. Enter the Set steering angle sensor menu and follow the
instructions displayed.
