Code C1264 Buick Description

The system relay is energized when the ignition is ON. The system relay supplies voltage to the valve solenoids and the pump motor. This voltage is referred to as the system voltage. The Electronic Brake Control Module (EBCM) microprocessor activates the valve solenoids by grounding the control circuit. The Solenoid Valve circuit is internal to the EBCM. The EBCM sets the OBDII code when the commanded state of the driver and the actual state of the control circuit do not match.
