Circuit/System Description

The brake pressure sensor is integral to the brake pressure modulator valve assembly. The electronic brake control module monitors the brake pressure sensor supply voltage and the signal voltage. The body control module sends a serial data message when the brake pedal is applied. The electronic brake control module uses input from the master cylinder pressure sensor for more accurate control during a vehicle stability enhancement system event.
