Windshield wipers
The combination switch (S4) signal is a voltage coded signal sent to the electronic ignition switch control module (N73) From there it is sent via CAN bus to the signal pick-up and actuation module (N10/1 [left-front]) N10/1 in turn switches on the wiper motor (M6/1) The windshield washer pump (M5/1) is also actuated by the signal pick-up and actuation module (N10/1 [left-front])

Rain sensor (B38)
The rain sensor signal is received by the roof control panel control module (N70) and then sent via CAN data line to the signal pick-up and actuation module (N10/1 [left-front])

Rear window wiper/washer
The switch signal is transferred as a voltage coded signal to the signal pick-up and actuation module (N10/[left-front]) The function wiping signal is transferred from the signal pick-up and actuation module (N10/[left-front]) to the PSE control module (A37) via CAN data line A37 in turn actuates the rear window wiper motor (M6/4) With the function washing, the switch signal is sent via CAN data line from the signal pickup and actuation module (N10/[left-front]) to the windshield washer pump (M5/1) or rear window washer pump (M5/3)

Headlamp cleaning system
The switch signal is transferred as a voltage coded signal to the signal pick-up and actuation module (N10/[left-front)) N10/1 in turn actuates the headlamp washer pump (M5/2)

The left/right front door switches (S17/3, S17/4) conduct a ground signal to the PSE control module (A37) In turn, the PSE control module (A37) sends a CAN message "Door open" to the roof control panel control module (N70)

Rear dome lamp - except model 208.4
The left/right rear door switches(S17/5, S17/6) send a ground signal to the PSE control module (A37) and in turn the PSE control module switches on the rear dome lamp (E15/3) Should the switch for the rear dome lamp be pressed on the roof control panel control module (N70), N70 will in turn send a CAN message to the PSE control module PSE control module will switch on the rear dome lamp (E15/3) as a result

Entrance/exit lamps
If a door is opened, the corresponding door switch sends a ground signal to the PSE control module (A37) As a result, the PSE control module (A37) sends a CAN message "Door open" to the passenger compartment bus The door control module responsible for the open door receives the CAN message and in turn switches on the corresponding entrance/exit lamp

Heated rear window
The switch for the heated rear window is integrated into the A/C pushbutton control module If the switch is pressed, a voltage coded signal is sent to the signal pick-up and actuation module (N10/1[left-front]) N10/1 in turn sends a CAN message "Heated rear window ON" to the PSE control module (A37) The relay integrated in the PSE control module (A37) is then actuated At the same time, the signal pick-up and actuation module (N10/1 [left-front]) actuates the LED in the heated rear window switch Should the switch be pressed again, the CAN message as sent by N10/1 to A37 and the LED in the switch is interrupted A timed shut-off occurs in approx 12 minutes, which is actuated in turn by N10/1

Heated rear window - Model 208.4
With the soft top up and locked, the roll bar/power soft top control module (N52) sends a coded signal via the CAN bus to the PSE control module (A37) When the soft top is opened, the signal is no longer sent to the PSE control module (A37) and the heated rear window (R1) is switched off The window cannot be switched back on until the top is in the up position and locked
