Fuel Run Out

All of the following conditions are met (1 trip detection logic):

  • Power switch on (IG).
  • The ECM receives the fuel empty low level signal from the combination meter assembly (meter ECU).
  • DTC detection conditions of either DTC P319000 or P319100 are met.

- (This DTC indicates that the vehicle ran out of fuel and does not indicate the malfunction of part.)

DTC stored

SAE Code: P3193

MONITOR DESCRIPTION

This DTC indicates that the vehicle ran out of fuel. If the ECM receives the low fuel level signal from the combination meter assembly (meter ECU) and the DTC detection conditions of either DTC P319000 or P319100 are met while the power switch is on (IG) or the engine is operating, the ECM stores this DTC.

CONFIRMATION DRIVING PATTERN

NOTICE:

If the MIL or a master warning light illuminates, immediately end the confirmation driving pattern. When DTCs P319000, P319100 and P319300 are output, the engine may stop. In this case, the HV battery will no longer be chargeable and the distance that the vehicle can be driven will be limited.

  1. Apply the parking brake firmly.
  2. Connect the Techstream to the DLC3.
  3. Turn the power switch on (IG).
  4. Turn the Techstream on.
  5. Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
  6. Turn the power switch off and wait for at least 30 seconds.
  7. Turn the power switch on (READY).
  8. Turn the Techstream on.
  9. Fully depress the accelerator pedal for 10 seconds with the vehicle stopped, the shift lever in P and the brake pedal depressed [A].

    NOTICE:

    As soon as the engine starts, release the accelerator pedal.

  10. Release the parking brake.
  11. Drive the vehicle at an average of approximately 40 km/h (25 mph) or more until the total engine operation time is 10 minutes or more [B].

    CAUTION:

    When performing the confirmation driving pattern, obey all speed limits and traffic laws.

    HINT:

    • It is not necessary to maintain the vehicle speed at 40 km/h (25 mph) throughout the road test.
    • If the engine stops, further depress the accelerator pedal to restart the engine.
  12. Enter the following menus: Powertrain / Engine / Trouble Codes [C].
  13. Read the pending DTCs.

    HINT:

    • If a pending DTC is output, the system is malfunctioning.
    • If a pending DTC is not output, perform the following procedure.
  14. Enter the following menus: Powertrain / Engine / Utility / All Readiness.
  15. Input the DTC: P319300.
  16. Check the DTC judgment result.

    Techstream Display

    Description

    NORMAL
    • DTC judgment completed
    • System normal

    ABNORMAL
    • DTC judgment completed
    • System abnormal

    INCOMPLETE
    • DTC judgment not completed
    • Perform driving pattern after confirming DTC enabling conditions

    HINT:

    • If the judgment result shows NORMAL, the system is normal.
    • If the judgment result shows ABNORMAL, the system is malfunctioning.
    • If the judgment result is INCOMPLETE, perform the Confirmation Driving Pattern and check the DTC judgment result again.

CAUTION / NOTICE / HINT

NOTICE:

  • Vehicle Control History may be stored in the hybrid vehicle control ECU assembly if the engine is malfunctioning. Certain vehicle condition information is recorded when Vehicle Control History is stored. Reading the vehicle conditions recorded in both the Freeze Frame Data and Vehicle Control History can be useful for troubleshooting.

    (Select Powertrain in Health Check and then check the time stamp data.)

  • If any "Engine Malfunction" Vehicle Control History item has been stored in the hybrid vehicle control ECU assembly, make sure to clear it. However, as all Vehicle Control History items are cleared simultaneously, if any Vehicle Control History items other than "Engine Malfunction" are stored, make sure to perform any troubleshooting for them before clearing Vehicle Control History.

HINT:

  • When DTCs P319000, P319100 and P319300 are output, the engine may stop.

    In this case, after adding fuel or performing repairs, clear the DTCs. Then turn the power switch off to return to the normal condition.

  • When this DTC is output and the engine is stopped, the HV battery cannot be charged since the vehicle is driven with the motor only. If the vehicle continues to be driven under this condition, the HV battery will become depleted and the power switch will not be able to be turned on (READY).

PROCEDURE

1.

CHECK SHORTAGE OF FUEL

(a) Check the amount of fuel remaining.

OK:

There is enough fuel.

HINT:

  • DTCs P319000, P319100 and/or P319300 may be output if the vehicle ran out of fuel in the past.
  • If not enough fuel is added, DTC P319000, P319100 or P319300 may be output again. If the engine cannot be started because the vehicle is out of fuel, add fuel until the fuel level warning turns off.
OK
