Monitor Description

The No. 2 skid control ECU (brake actuator assembly) monitors the ratio of output value of the brake pedal stroke sensor assembly and reaction force pressure sensor.

When in linear mode (switching solenoid (SSA) on), the brake pedal is being operated and the ratio of the output value of the brake pedal stroke sensor assembly and reaction force pressure sensor is outside the normal range, the No. 2 skid control ECU (brake actuator assembly) judges that the ratio of the output value of the brake pedal stroke sensor assembly and reaction force pressure sensor is abnormal and illuminates the MIL and stores this DTC.
