Set the clock spring contact to center position - AR46.10-P-0200-01I

The center position of the fanfare horns and airbag clock spring contact (A45) is crucial for the trouble-free function of the airbag system and signaling system. When removed this is guaranteed by the screws (32h).

If the fanfare horns and airbag clock spring contact (A45) is nevertheless twisted, e.g. when the steering coupling is removed or when the screws are unscrewed completely (32h), the center position of the fanfare horns and airbag (A45) can be adjusted as per the following work procedure.
