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

When the brakes are operating, the reservoir cut solenoid valves supply brake fluid from the brake master cylinder reservoir assembly to the pump motor as necessary.

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