Initialise steering angle sensor


This function is used to initialise the steering angle sensor. This shall be done if:

Note:

Test conditions:

Procedure:

  1. Check that the steering wheel is in correct position when the front wheels stand straight.

  2. Drive the car straight ahead on level ground at max. 20 km/h to check that the car does not veer when the steering wheel is held in position for driving straight ahead.

  3. Stop the car and turn the steering wheel almost to lock both to the right and left.

  4. Set the steering wheel in position for travel straight ahead.

  5. Select the function: "Steering wheel angle sensor initialisation".

  6. The function starts, a dialogue shows: ”Adaptation in order”, - confirms that initiation is performed.

    • If the text "Adaptation not possible" is shown, check that the steering angle sensor is installed correctly and that the steering wheel is in the middle position.

  7. Complete the function and disconnect the diagnostic tool.

  8. The control light for steering servo is on.

  9. Test-drive a short distance (10-20 metres) straight ahead to learn the middle position.

  10. Let the engine run at idle, set the steering wheel in middle position (front wheels straight ahead) for at least 2 seconds without touching the steering wheel.

  11. Turn the steering wheel to left full lock and hold it there until you hear 3 beeps.

  12. Turn the steering wheel to right full lock and hold it there until you hear 3 beeps.

  13. Turn back the steering wheel to middle position (front wheels straight ahead). The control light for electromechanical steering turns off.

  14. Check that no error codes are stored in the ABS control unit or in the control unit for electromechanical power steering.
