  1. Connect the Techstream to the DLC3.
  2. Turn the engine switch on (IG) [B].
  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 engine switch off.
  7. Disconnect the Techstream.
  8. Disconnect the cable from the negative (-) battery terminal and wait for 1 minute.
  9. Connect the cable to the negative (-) battery terminal.
  10. Connect the Techstream to the DLC3.
  11. Turn the engine switch on (IG).
  12. Turn the Techstream on.
  13. Wait 1 second or more [A].
  14. Enter the following menus: Powertrain / Engine / Trouble Codes [B].
  15. 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.
  16. Enter the following menus: Powertrain / Engine / Utility / All Readiness.
  17. Input the DTC: P060747 or P060787
  18. 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.
    • [A] to [B]: Normal judgment procedure.

      The normal judgment procedure is used to complete DTC judgment and also used when clearing permanent DTCs.

    • When clearing the permanent DTCs, do not disconnect the cable from the battery terminal or attempt to clear the DTCs during this procedure, as doing so will clear the universal trip and normal judgment histories.

CAUTION / NOTICE / HINT

NOTICE:

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

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.
