Monitor Description

The No. 2 skid control ECU (brake actuator assembly) monitors the output value of the brake pedal stroke sensor assembly, and if the following conditions are detected, the No. 2 skid control ECU (brake actuator assembly) judges that the brake pedal stroke sensor assembly has a malfunction and illuminates the MIL and stores a DTC.

• The power supply voltage ratio of the brake pedal stroke sensor 1 is outside the normal range.

  HINT: 

  The power supply voltage ratio is the ratio of the voltage of SKS1 and VSK1.

• The difference between the current power supply voltage ratio and the previous power supply voltage ratio of the brake pedal stroke sensor 1 exceeds a specific value (improbable sudden change repeats).

  HINT: 

  The power supply voltage ratio is the ratio of the voltage of SKS1 and VSK1.
