SFI SYSTEM(w/o Canister Pump Module), Diagnostic DTC:P06579E

DTC Code DTC Name
P06579E Actuator Supply Voltage "A" Stuck On

MONITOR DESCRIPTION

The ECM monitors the output voltage to the throttle actuator. This self-check ensures that the ECM is functioning properly. The output voltage is usually 0 V when the power switch is turned off. If the output voltage is 7 V or higher when the power switch is turned off, the ECM will illuminate the MIL and store this DTC when the power switch is turned on (IG).

CONFIRMATION DRIVING PATTERN


  1. Connect the GTS to the DLC3.

  2. Turn the power switch on (IG).

  3. Turn the GTS on.

  4. Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).

  5. Turn the GTS off.

  6. Turn the power switch off.

  7. Disconnect the GTS.

  8. Disconnect the cable from the negative (-) auxiliary battery terminal and wait for 1 minute.

  9. Connect the cable to the negative (-) auxiliary battery terminal.

  10. Turn the power switch on (IG) and wait 10 seconds or more.

  11. Turn the power switch off and wait 15 seconds or more.

  12. Connect the GTS to the DLC3.

  13. Turn the power switch on (IG).

  14. Turn the GTS on.

  15. With power switch on (IG) and wait for 5 seconds or more.

  16. Enter the following menus: Powertrain / Engine / Trouble Codes.

  17. Read the pending DTCs.

    Tech Tips


    • If a pending DTC is output, the system is malfunctioning.

    • If a pending DTC is not output, perform the following procedure.

  18. Enter the following menus: Powertrain / Engine / Utility / All Readiness.

  19. Input the DTC: P06579E.

  20. Check the DTC judgment result.

    GTS 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

    Tech Tips


    • If the judgment result shows NORMAL, the system is normal.

    • If the judgment result shows ABNORMAL, the system is malfunctioning.

CAUTION / NOTICE / HINT

Note


  • Vehicle Control History may be stored in the hybrid vehicle control ECU 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.

  • If any "Engine Malfunction" Vehicle Control History item has been stored in the hybrid vehicle control ECU, 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.

  • After turning power switch off, waiting time may be required before disconnecting the cable from the negative (-) auxiliary battery terminal. Therefore, make sure to read the disconnecting the cable from the negative (-) auxiliary battery terminal notices before proceeding with work.

Tech Tips

Read freeze frame data using the GTS. The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air fuel ratio was lean or rich, and other data from the time the malfunction occurred.

PROCEDURE


  1. CLEAR DTC
