Description of functions

Each solenoid adjusts the pressure applied to each wheel cylinder to control the vehicle.
While an abnormal diagnostic code is being output, the fail safe function turns OFF the solenoid relay forcibly. Therefore the solenoid will not be turned ON.
The solenoid relay and the solenoid are integrated into the brake actuator ASSY.
