Calibrate internal steering angle sensor

5.1

Requirements

 Front axle is measured and set
 Ignition and engine on.
 Vehicle stationary and wheels in straight-ahead position - on an axle measuring bench.
 Steering angle sensor is activated.
5.2

Calibration

1. Turn steering wheel +/- 30° from straight-ahead position.
2. Return steering wheel to straight-ahead position.
3. Select adjusting channel 60 as the base setting.
4. Steer to the left and right of the center position until the steering angle sensor indicates the status "calibrated".
