Function 

The pressing of the fanfare horn system button is read in by the steering column module via the steering LIN and passed on to the central gateway control unit via the chassis CAN. The central gateway control unit passes on the request to the front SAM control unit via the interior CAN.

The front SAM control unit actuates the fanfare horns via the fanfare horns relay.

IMPORTANT The circuit status is transmitted by the EIS [EZS] control unit on the interior CAN.
