When Pressure Holds

The control unit closes the cut valve 1 port by supplying current to the cut valve 1. Since power is not applied to the suction valve 1, the suction valve 1 port closes. The ABS IN valve port opens and the ABS OUT valve port closes because power is not supplied to the ABS OUT valve. Since each port of the cut valve 1 and suction valve 1 is closed, the paths to the master cylinder, front RH caliper, and pump and reservoir are cut to maintain fluid pressure of the front RH caliper.
