Steering Angle Sensor (SAS) Calibration

PURPOSE OF calibration
1. On vehicle control, an ESC analyzes the intention of the driver.
2. An ESC recognizes a steering angle which a driver rotates through the steering angle sensor.
3. A steering angle sensor used in ESC8 adjusts 0° setting of steering wheel through K-line or CAN communication.

1. 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.
2. Connect Hi-scan to the vehicle.
3. Select Brake system.
4. Select Steering angle sensor (SAS) calibration.
