C12FE Description
The boost pressure valve is internal to the brake pressure modulator. The Electronic Brake Control Module (EBCM) monitors the boost pressure. The boost valve controls the amount of hydraulic boost required during braking or a vehicle stability event. When a boost fault condition is detected, the boost control will continue applying as much pressure as possible until boost pressure is no longer available.
