This function is used to calibrate the steering angle sensor.
The function is used when:
The steering angle sensor has been replaced.
The ABS control unit has been replaced.
The vehicle front settings have been changed.
To ensure calibration is successful, the conditions set out in point 4 must be fulfilled.
Note:
Following calibration of the steering angle sensor, it is necessary to adjust the end positions for the power steering. This is done from the power steering system.
Test conditions:
Ignition on, engine off.
Battery voltage above 12 V.
Steering wheel straight when wheels point straight ahead.
Procedure:
Check that the steering wheel is straight and the front wheels point straight ahead.
Select the "Steering angle calibration" function and press "OK".
A dialogue box shows: "Turn the steering wheel approximately 30° right or left, then back to the back to the centre position". Press "OK" to continue.
The calibration conditions are checked. If the conditions are fulfilled, 111 is displayed. If a zero is displayed, this means that one of the calibration conditions has not been fulfilled.
First figure from left = Within permitted steering angle tolerance range (less than 7.5°).
Second figure from left = Vehicle speed less than 1 km/h i.e. vehicle stationary.
Third figure from left = Chassis number correctly received.
When all the conditions are fulfilled, press "OK" to calibrate the steering angle sensor.
If calibration is successful, the display shows:
"Steering angle sensor initiated".
If calibration fails, check the test conditions and the conditions set out in point 4.
Press "OK" to exit the function.
Select the function "Adjusting end position" in the power steering system.
