Function
The washing function is activated by rotating and holding the combination switch (S4) in position "I" (rear window). In this case the rear-end door washer fluid pump (M5/3) is actuated directly by the front SAM control unit with fuse and relay module (N10/1).

The request to wash the rear window is read by the front SAM control unit with fuse and relay module (N10/1) via CAN-B and transmitted to the rear SAM control unit with fuse and relay module (N10/2).
The rear SAM control unit with fuse and relay module (N10/2) then actuates the rear-end door wiper motor (M6/4).
