Monitor Description

C0571, C0572: 

1. When it is determined that the output of the accumulator pressure sensor is outside the specified range, the skid control ECU assembly determines that the output of the accumulator pressure sensor is abnormal and illuminates the MIL and stores a DTC.

C0574: 

1. When the volume of brake fluid within the accumulator is below a certain amount, the skid control ECU assembly operates the pump motor. When the pump motor is being operated and the output value of the accumulator pressure sensor does not change substantially for a certain period of time, the skid control ECU assembly judges that the accumulator pressure sensor has a stuck malfunction and illuminates the MIL and stores this DTC.

C121A: 

1. When the value output from the accumulator pressure sensor is noisy, the skid control ECU assembly determines that the output of the accumulator pressure sensor is noisy and illuminates the MIL and stores a DTC.

C14D0: 

1. When it is determined that the power source voltage of the accumulator pressure sensor is outside the normal range, the skid control ECU assembly determines that there is a power source malfunction and illuminates the MIL and stores a DTC.
