Title: A25A-FXS (ENGINE CONTROL): SFI SYSTEM (w/o Canister Pump Module): P06579E; Actuator Supply Voltage "A" Stuck On; 2019 - 2020 MY RAV4 HV [11/2018 - 08/2020]

DTC

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 to on (IG).

DTC No.

CONFIRMATION DRIVING PATTERN

  1. Connect the Techstream to the DLC3.
  2. Turn the power switch on (IG).
  3. Turn the Techstream on.
  4. Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
  5. Turn the Techstream off.
  6. Turn the power switch off.
  7. Disconnect the Techstream.
  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) [A].
  11. Wait 10 seconds or more.
  12. Turn the power switch off [B].
  13. Wait 15 seconds or more.
  14. Connect the Techstream to the DLC3.
  15. Turn the power switch on (IG).
  16. Turn the Techstream on.
  17. Wait 5 seconds or more [C].
  18. Enter the following menus: Powertrain / Engine / Trouble Codes [D].
  19. 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.
  20. Enter the following menus: Powertrain / Engine / Utility / All Readiness.
  21. Input the DTC: P06579E.
  22. 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 is NORMAL, the system is normal.
    • If the judgment result is ABNORMAL, the system is malfunctioning.
    • If the judgment result is INCOMPLETE, perform steps [B] through [D] 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.

  • 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:

Read Freeze Frame Data using the Techstream. 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.
