CONFIRMATION DRIVING PATTERN

  1. Connect the GTS to the DLC3.
  2. Turn the ignition switch to ON.
  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 ignition 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. Connect the GTS to the DLC3.
  11. Turn the ignition switch to ON.
  12. Turn the GTS on.
  13. Wait 1 second or more.
  14. Enter the following menus: Powertrain / Engine / Trouble Codes.
  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.

    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

    HINT:

    • If the judgment result is NORMAL, the system is normal.
    • If the judgment result is ABNORMAL, the system is malfunctioning.

CAUTION / NOTICE / HINT

NOTICE:

  • After the ignition switch is turned off, there may be a waiting time before disconnecting the negative (-) auxiliary battery terminal.

  • When disconnecting and reconnecting the auxiliary battery.

    HINT:

    When disconnecting and reconnecting the auxiliary battery, there is an automatic learning function that completes learning when the respective system is used.

HINT:

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

(a) Clear the DTCs.

Powertrain > Engine > Clear DTCs

(b) Turn the ignition switch off.

NEXT

2.

READ OUTPUT DTC (DTC P060747 OR P060787)

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

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

(c) Wait 1 second or more.

(d) Read the DTCs.
