When the brake pedal is not operated and the servo pressure sensor output value exceeds a specific value, or the value is less than a specific value for a certain amount of time, the skid control ECU (brake booster with master cylinder assembly) judges that the zero point of the servo pressure sensor is abnormal and illuminates the MIL and stores this DTC.
