Steering Angle Sensor (SAS) Calibration

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.
