Convenience closing/opening function via transmitter key (A8/1)

All windows and the soft top can be closed or opened by actuating the unlock and lock buttons on the transmitter key (A8/1). The request for convenience closing/opening is transmitted by the left front IR receiver (A26/1) or the right front IR receiver (A26/2) (only  and ) to the left door control module (N69/1) or the right door control module (N69/2). It relays the actuation request to the EIS control module (N73) via the CAN class B bus.

When the transmitter key (A8/1) is recognized the EIS control module (N73) transmits the request for "Closing" or "Opening" the window and the soft top to the left door control module (N69/1), to the right door control module (N69/2) and to the soft top actuation control module (N52) via the CAN class B bus.

The left door control module (N69/1) then actuates the left front power window motor (M10/3), the right door control module (N69/2) actuates the right front power window motor (M10/4) in the "closing" or "opening" direction.

The soft top actuation control module (N52) actuates the left rear power window motor (M10/5), the right rear power window motor (M10/6) as well as the soft top actuation hydraulic unit (A7/5) of the soft top in the "closing" or "opening" direction.

 The soft top is only opened and closed when all side windows are open. This prevents collisions between the soft top and the side window.
