^ SOS pushbutton switch (S93/3) ((United States of America) only)

Function
The overhead control panel control unit is connected to the interior CAN for exchanging data, reads in sensors, switches and consumers and actuates their voltage supply, function along with the switch and controls illumination.

Controlling
^ the interior illumination (IBL)
^ the tilting/sliding roof (SHD)
(model 221 with code (414) Power glass tilting/sliding roof and with model 216)
^ the top sliding panoramic glass sunroof
(with code (413) Panoramic glass sunroof with top sliding sunroof)

Gateway to the interior CAN
^ Information from the rain/light sensor (B38/2)
^ Anti-dazzle information of mirror dimming (A67h3)

Reading in of sensors

^ Hall sensor 1, roof system (M12b1)
^ Hall sensor 2, roof system (M12b2)
^ Front roller sun blind Hall sensor 1 (M54b1)
^ Front roller sun blind Hall sensor 2 (M54b2)
^ Rear roller sun blind Hall sensor 1 (M54/1b1)
^ Rear roller sun blind Hall sensor 2 (M54/1b2)

Model 221 with code (414) Power glass tilting/sliding roof and for model 216:
^ Roof system Hall sensor 1
^ Roof system Hall sensor 2

Reading in of integrated switches
^ Front dome lamp switch
^ Rear dome lamp switch (model 221)
^ Coat hook lamp switch (model 216)
^ Door contact ON and OFF switch
^ Left front reading lamp switch
^ Right front reading lamp switch
