The steering angle sensor is placed on the steering column or in the "SZL switch centre steering wheel", if the car is equipped with this. The steering angle sensor is permanently power supplyed and at a power interruption the ABS/DSC warning lamp can be switched on. In some cases it is enough to drive the car a short distance with a speed of at least 25 km/h, or by turning the steering wheel to the left and right end position a few times for the warning lamp to turn off. If this is not enough you can perform a steering angle calibration with this function.
Note:
Steering angle calibration must be done if:
The "SZL switch centre steering wheel" has been replaced.
The "SZL switch centre steering wheel" has been coded.
The "DSC" control unit has been replaced.
The "DSC" control unit has been coded.
The steering angle sensor has been replaced.
A repair or adjustment of the steering or the front axle has been done in such a way that the car's geometry has changed.
If the "SZL switch centre steering wheel" or "DSC" control unit have been replaced, this must first be coded before the steering angle can be calibrated.
Test prerequisites:
Ignition on, engine off.
No faults in the system.
The car shall be on a flat surface with the front wheels straight ahead.
Procedure:
Set the steering wheel and the front wheels in the exact position straight ahead (It is enough with an measurement by eye).
Choose the funktion and perform the calibration.
After the function has been performed the ignition should be turned off for 10 seconds to store the calibration.
