WHEEL SPEED AND MODULATOR CONTROL
When the wheel speed drops sharply below the vehicle speed, the inlet valve closes to retain the caliper fluid pressure. When the wheel speed
drops further, the outlet valve opens momentarily to reduce the caliper fluid pressure. The pump motor starts at this time. As the wheel speed is
restored, the inlet valve opens momentarily to increase the caliper fluid pressure.
