Test conditions:

Procedure:

  1. Start the engine and turn the steering wheel approximately 90° to the left and right.

  2. Test drive on a level surface at a maximum speed of 30 km/h and check that the steering wheel is in the correct position when driving in a straight line.

  3. Stop the vehicle while driving in a straight line and ensure that the steering wheel has not turned.

  4. Select the "Power steering" function.

  5. Once this function is complete, select the "Initialise steering angle sensor" function.

  6. A dialogue box shows: "correct” to confirm that initialisation has been successful. The steering servo test lamp comes on.

  7. Drive a short distance in a straight line and turn the steering wheel approximately 360° to the left and right to initialise the steering angle sensor. The steering servo test lamp goes out.

  8. Check that no trouble codes are stored in the power steering control unit.

  9. Exit the function.

    • If the function fails, check that the steering wheel is in the centre position and that the components are correctly fitted.
