Circuit/System Description

The electronic brake control module (EBCM) monitors the brake pressure sensor voltage, vehicle speed, and a serial data message from the body control module (BCM) that the brake pedal is either Applied or Released. When the vehicle is stopping the EBCM detects the brake pressure sensor voltage increases and correlates the readings to the serial data message from the BCM that the brake pedal is applied, and the vehicle is slowing down, or when the vehicle is accelerating, the brake pedal is Released and brake pressure sensor voltage returns to 0 volts.
