GENERAL DATA
Scheme 102
Scheme 103
- PURPOSE OF calibration On vehicle control, an ESC analyzes the intention of the driver. An ESC recognizes a steering angle which a driver rotates through the steering angle sensor. A steering angle sensor used in ESC adjusts 0° setting of steering wheel through K-line or CAN communication.
- STEERING ANGLE SENSOR (SAS) CALIBRATION METHOD

- Align the wheel to the straight line (steering wheel < ± 5°) ex) Perform the wheel alignment first. Align the wheel to the straight line. A driver moves the vehicle to the front and back about 5 meters twice or three times.
- Connect Scan tool to the vehicle.
- Select Brake system.
- Select Steering angle sensor (SAS) calibration.
- Perform the Steering angle sensor (SAS) calibration.
- Perform the procedure continuously.
- The procedure is finished. Push the "ESC" key.
- Scanner OFF.
- Remove the scanner from the vehicle.
- Confirm the Steering angle sensor (SAS) calibration as driving the vehicle (turn left once, turn right once).
