Inputs And Outputs - Brake System Control Module (BSCM)

The BCM receives the Steering Angle Sensor (SAS) data from the Electric Power Steering (EPS) module in the steering gear and broadcasts the data on the Controller Area Network - Flex-Data (CAN-FD) data bus for BSCM calculations. The BCM gates all LIN data from the HDC, HOLD and ESC/TCS switches to the BSCM.

The BSCM is powered by a fuse in the Power Distribution Center (PDC).
