Monitor Description

When the brake pedal is not operated and the value of the reaction force pressure sensor exceeds a specific value, or the value is less than a specific value for a certain amount of time, the No. 2 skid control ECU (brake actuator assembly) judges that the zero point of the reaction force pressure sensor is abnormal and illuminates the MIL and stores this DTC.
