Each solenoid adjusts the pressure which affects each wheel cylinder according to signals from the skid control ECU assembly and controls the vehicle.

The master cut solenoid (SMC1/2) is closed and blocks the master cylinder pressure from the electronically controlled brake system control pressure when the system is normal. The master cut solenoid is open and sends the master cylinder hydraulic pressure to the non-assisted brake wheel cylinders during fail-safe operation due to a system malfunction.
