N10/2 Rear signal acquisition and actuation module (SAM)

Location
The rear SAM [signal acquisition and actuation module] is located on the center tunnel.

Task
The rear SAM is connected for exchanging data over the interior CAN (CAN-B).
Limit switches supply systems and control units with voltage to match the function sequence. The requests are sent to the rear SAM over the interior CAN or over read-in switches and sensors.
The rear SAM reads in signals from the restraint systems control unit (N2/7) discretely and passes these on.
The individual components are protected via fuses contained in the fuse and relay block.
