- 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).
