Tasks of the SBC control unit (A7/3n1):
- Records the driver's brake application via the SBC pedal value sensor (B37/1) and the front axle pre-pressure sensor (A7/3b1).
- Supplies the ESP with data about how rapidly the driver wishes to brake and the brake pressures at the individual wheels (via its own CAN).
- Supplies the ESP with the vehicle speed signal (directly and via its own CAN).
- Carries out all control functions during normal braking.
- Performs all pressure control functions for ABS, ASR, ESP and BAS control.
- Passes on the brake lights signal to the rear SAM control unit with fuse and relay module (N10/2) to directly actuate the brake lights further and with the CAN via the ESP, SPS [PML] and BAS control unit (N47-5) (model 230) or ESP control unit (N47-5) (model 211).
