When the front wheel speed rises sharply above the vehicle speed, the TCS NC valve opens, the TCS NO valve closes,
and the pump motor starts to intensify the front caliper fluid pressure. When the wheel speed drops, the front inlet
valve closes momentarity to retain the front caliper fluid pressure. When the wheel speed drops further, the front
outlet valve opens momentarily to reduce the front caliper fluid pressure.
