The sensor output voltage 2 (SKS2) is less than 0.3 V for 0.2 seconds or more.
  • Wire harness and connector
  • Brake pedal stroke sensor assembly

Comes on
  • SAE Code: P05DD
  • Output ECU: No. 2 skid control ECU (brake actuator assembly)

P05DB1F

Brake Pedal Position Sensor "B" Circuit Intermittent

The difference between the current value and previous value of the sensor output voltage 2 (SKS2) is 8.5% or more for 0.2 seconds or more.
  • Wire harness and connector
  • Brake pedal stroke sensor assembly

Comes on
  • SAE Code: P05DF
  • Output ECU: No. 2 skid control ECU (brake actuator assembly)

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 2 is outside the normal range.

    HINT:

    The power supply voltage ratio is the ratio of the voltage of SKS2 and VSK2.

  • The difference between the current power supply voltage ratio and the previous power supply voltage ratio of the brake pedal stroke sensor 2 exceeds a specific value (improbable sudden change repeats).

    HINT:

    The power supply voltage ratio is the ratio of the voltage of SKS2 and VSK2.

CONFIRMATION DRIVING PATTERN

NOTICE:

When performing the normal judgment procedure, make sure that the driver door is closed and is not opened at any time during the procedure.

HINT:

  • After repair has been completed, clear the DTC and then check that the vehicle has returned to normal by performing the following All Readiness check procedure.
  • When clearing the permanent DTCs, refer to the "CLEAR PERMANENT DTC" procedure.
  1. Connect the GTS to the DLC3.
  2. Turn the ignition switch to ON and turn the GTS on.
  3. Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
  4. Turn the ignition switch off.
  5. Turn the ignition switch to ON (READY) and turn the GTS on.
  6. Wait for 1 second or more. [*]

    HINT:

    [*]: Normal judgment procedure.

    The normal judgment procedure is used to complete DTC judgment and also used when clearing permanent DTCs.

  7. Enter the following menus: Chassis / Brake/EPB / Utility / All Readiness.
  8. Check the DTC judgment result.

    HINT:

    • If the judgment result shows NORMAL, the system is normal.
    • If the judgment result shows ABNORMAL, the system has a malfunction.
    • If the judgment result shows INCOMPLETE, perform driving pattern again.
