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:
