The SAM control unit on the passenger side (N10/11) has the following tasks:

Controlling
^ Headlamp cleaning system (HCS)
^ Auxiliary water pump
^ Washer fluid hose heater
^ Passenger compartment lighting
^ Exterior lights

Scanning the following switches:
^ Voltage charged radiator fluid control switch (S41) together with the water level control switch Windshield wiper system (S42)
^ Electronic alarm system engine hood contacts (S62)
^ Storage compartment switches (S85)
^ Glove compartment illumination switch (E13/2)

Reading of the following signals:
^ Brake lining wear front left

Scanning the following signals:
^ Circuit 61 (the pre-exciter current is generated in the SAM by a series resistor)

Switching loads via semiconductor switches:
^ Stationary and park lights front right (E1e3)
^ Dimmer lights front right (E1e2)
^ High beam/headlamp front right (E2e1)
^ Fog lamps front right (E1e4)
^ Driving direction display front right
^ Sidemarker front right (only in USA)
^ Storage compartment lighting (E36)
^ Footwell lighting (E17/1 and E17/2)
^ Washer nozzle heating (R2/1)
^ Washer nozzle hose heater (R2/11)
^ SRA washer pump (K 26/2)
^ Auxiliary water pump (M13/2)

Switches in the following relays:
^ Fanfare (K39)
^ Transmission oil cooler

The SAM control unit on the passenger side (N10/11) assumes the following EHB signal switches:
^ Alarm lines
^ Speed status signal
^ Brake light switch signal
^ Active recoil

The SAM control unit on the passenger side (N10/11) is connected to the passenger compartment CAN for the exchange of data.
