The ABS solenoid relay and master cylinder cut solenoid valves are built into the brake actuator assembly.

Depending on the operating conditions, the master cylinder cut solenoid valves regulate the brake fluid pressure generated by the pump motor.

When this DTC is stored, the fail-safe function operates and the ABS solenoid relay is turned off to prevent the master cylinder cut solenoid valves from operating.
