If during the pressure hold or pressure decrease mode the electronic brake control module (EBCM) senses that wheel slip has reduced, the EBCM will increase the pressure to the affected wheels by applying master cylinder pressure. The inlet valve is opened and the outlet valve is closed, now base brake master cylinder pressure can be applied to the wheel.
