Circuit/System Description

The electronic brake control module (EBCM) monitors the ignition voltage. If the voltage level is too high, damage may result in the system. When a high voltage condition is detected, the EBCM turns OFF the system relay which removes battery voltage from the solenoid valves and pump motor.
