This basic setting is used to adapt the steering angle sensor for the ABS/ESP control unit. This must be done if:
The ABS/ESP control unit has been replaced.
Note:
During the basic setting, the ignition must not be switched off.
If the steering angle sensor has been replaced or disconnected from the battery, the initialization is lost and a fault code is stored. With a short driving straight ahead and a little movement of the steering wheel (about 30°) to the left and to the right, the sensor initiates automatically. The fault code becomes intermittent and can now be erased.
Test prerequisites:
Ignition on.
Battery voltage above 12V.
The ABS/ESP control unit correctly coded.
Procedure:
Check that the steering wheel is in the correct position when the front wheels are straight ahead.
Drive the car straight ahead on a flat surface, at no more than 20 km/h, to check that the car does not pull to one side when the steering wheel is held in the straight ahead position.
Stop the car and make sure that the front wheels and the steering wheel are aligned.
Choose the function: "Adaptation of steering angle sensor".
The function starts and the text: ”Adaption correct” confirms that the adaptation has been done.
If the text "adaption not possible" appears, check if the steering angle sensor is correctly installed and the steering wheel is in the straight ahead position.
Drive a short distance straight ahead , with a little movement of the steering wheel (about 30°) to the left and to the right to initiate the steering angle sensor automatically.
Check that no fault codes are stored in the ABS system.
Exit the function.
