Steering wheel angle programming


Note:

According to the computer version, status of the Steering wheel angle sensor can be read from either data list or under adjust.

If the car is fitted with ESP, removing the ESP sensors programming might be necessary. Depending on the computer version, this function is avaible in this system or in the ABS/ESP system.

To obtain accurate straight wheel position , this operation must be performed on a front axle adjustment bench, particularly for vehicles fitted with ESP.

Test prerequisites:

Procedure following replacement of the computer or steering column assembly:

  1. Datalist parameter "Steering wheel angle programming" must be "Status 1" or "Status 2" and the service warning light flashing or continuously lit.

  2. Turn the steering wheel to full left and then to full right, then back to straight.

  3. Activate the function "Steering wheel angle programming"

  4. Turn the steering wheel to full left and then to full right.

  5. Datalist parameter "Steering wheel angle programming" must now be "Status 4".

  6. Check that the datalist parameter "Steering wheel angle" not varies more than +/- 5 d˚ with the wheels straight ahead.

Procedure to follow after disconnecting the battery or loss of supply to the computer:

  1. Datalist parameter "Steering wheel angle programming" must be "Status 3".

  2. Turn the steering wheel to full left and then to full right, then return slowly to the centre point (less than 200°/s)

  3. Datalist parameter "Steering wheel angle programming" must now be "Status 4".
