Component Functional Description - Brake System Control Module (BSCM)

The BSCM is bolted to the Hydraulic Assembly. The BSCM monitors several inputs used for normal vehicle braking as well as detection and operation of anti-lock braking, traction, and electronic stability controls. The signals that are monitored are listed below. The BSCM directly monitors the signals for operating the:

• Brake Pedal Position Sensor(s)
• Master Cylinder Pressure Sensor (non-eBooster System)
• Brake Pedal Simulator Pressure Sensor (eBooster System)
• Hydraulic pressure sensors in each hydraulic circuit
• Wheel Speed Sensors
• Steering Angle Sensor
• Dynamic Sensor

These inputs are used to control the following output devices:

• Motor/actuator
• Hydraulic pump
• Inlet Check Valves
• Outlet Check Valves
