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 repairing 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.
3. Wait until the following instruction is displayed and press
Yes
after completing the instructions shown.
