Note

C05C000

Brake Pedal Position Sensor "A"

When the vehicle speed is 40km/h (25 mph) or more, a valid brake pedal stroke sensor zero point is not memorized.
  • Valid brake pedal stroke sensor assembly zero point not memorized.

    (Calibration not performed or not completed)

  • Wire harness and connector
  • Brake pedal stroke sensor assembly

Comes on
  • SAE Code: C05C0
  • Output ECU: No. 2 skid control ECU (brake actuator assembly)

HINT:

During Dealer Mode, related DTCs are cleared (except SAE code).

MONITOR DESCRIPTION

If brake pedal stroke sensor assembly zero point calibration is not performed after any of the following procedures are performed and the vehicle is driven at a certain speed or more, the No. 2 skid control ECU (brake actuator assembly) judges that learning has not been completed, the MIL is illuminated and a DTC is stored.

  • The No. 1 skid control ECU (brake booster with master cylinder assembly) has been replaced with a new one.
  • After the brake pedal stroke sensor assembly, brake pedal, brake booster with master cylinder assembly, brake actuator assembly or yaw rate and acceleration sensor (airbag ECU assembly) has been removed and installed or replaced, the zero point is cleared.

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. Drive the vehicle at a speed of 40 km/h (25 mph) or more for 1 minute. [*]

    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.
