Note

P05FF62

Brake Pressure Sensor / Brake Pedal Position Sensor Signal Compare Failure

The difference between brake pedal stroke sensor assembly output value and reaction force pressure sensor output value is above the threshold for a certain period of time.

  • Brake booster with master cylinder assembly
  • Brake pedal stroke sensor assembly
  • Brake pedal stroke sensor assembly installation
  • Brake fluid leaks

Comes on

  • SAE Code: P05FF
  • Output ECU: Both skid control ECUs

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.

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. Depress the brake pedal 3 or more times. [*]

    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.

CAUTION / NOTICE / HINT

NOTICE:

  • After replacing or reinstalling the brake pedal stroke sensor assembly, perform "Calibration" after performing "Reset Memory".

PROCEDURE

1.

CUSTOMER PROBLEM ANALYSIS (CHECK CONDITION WHEN MALFUNCTION OCCURRED) AND FREEZE FRAME DATA

(a) Interview the customer to check the vehicle conditions when the brake system warning light (red indicator) and brake system warning light (yellow indicator) illuminated.

(b) Using the GTS, check for Freeze Frame Data that is recorded when a DTC is stored.

HINT:

  • Freeze Frame Data is only stored once when a DTC is stored.
  • If other DTCs are output, repair any malfunctions related to those DTCs first, and then reproduce the conditions that caused DTC P05FF62 to be stored based on the interview with the customer.
