Confirmation Driving Pattern

HINT: 

• It is necessary that the response of the heated oxygen sensor is normal in order to confirm DTCs P0420-00 and P0430-00. Therefore, perform the confirmation driving pattern for the heated oxygen sensor monitor before performing the drive pattern for the catalyst efficiency monitor.
• Performing this confirmation driving pattern will activate the catalyst efficiency monitor. This is very useful for verifying the completion of a repair.
• After repair has been completed, clear the DTC and then check that the vehicle has returned to normal by performing the following All Readiness check procedure.

  Refer to DTC CHECK / CLEAR [11/2017 - ]

• When clearing the permanent DTCs, refer to the "CLEAR PERMANENT DTC" procedure.

1. Connect the Techstream to the DLC3.
2. Turn the engine 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 engine switch off and wait for at least 30 seconds.
6. Turn the engine switch on (IG).
7. Turn the Techstream on.
8. Enter the following menus: Powertrain / Engine / Monitor / Current Monitor.
9. Check that Catalyst Efficiency / Current is Incomplete.
10. Start the engine and warm it up until the engine coolant temperature is 75°C (167°F) or higher with the shift lever in P [A].

    HINT: 

    In order to keep the idle stable, turn the A/C and all other electric loads off and do not perform any shift operations.

11. Drive the vehicle at approximately 60 km/h (37 mph) for 10 minutes or more [B].
    WARNING:

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

    HINT: 

    Drive the vehicle while keeping the engine load as constant as possible.

12. With the shift lever in M, drive the vehicle at 60 km/h (37 mph), and then decelerate the vehicle by releasing the accelerator pedal for 5 seconds or more to perform the fuel-cut [C].
    WARNING:

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

13. Enter the following menus: Powertrain / Engine / Monitor / Current Monitor / O2 Sensor / Details / SLOW RESPONSE B1S2 [D].
14. Check the Test Value for SLOW RESPONSE B1S2.

    HINT: 

    • If Test Value displays a value larger than 0, perform the following procedure, as the O2 Sensor monitor is finished.
    • If Test Value displays 0, perform step [C] until it displays a value larger than 0, as the O2 Sensor monitor is not finished.
15. Turn the engine switch off and wait for at least 30 seconds [F].
16. Turn the engine switch on (IG).
17. Turn the Techstream on.
18. Start the engine and warm it up until the engine coolant temperature is 75°C (167°F) or higher [G].
19. Drive the vehicle at approximately 60 km/h (37 mph) for 10 minutes or more [H].
    WARNING:

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

    HINT: 

    • Drive the vehicle while keeping the engine load as constant as possible.
    • The monitor item will change to Complete as the Catalyst Efficiency monitor operates.
20. Enter the following menus: Powertrain / Engine / Trouble Codes [I].
21. Check if any DTCs are stored.

    HINT: 

    • If the monitor item does not change to Complete, and no DTCs are stored, perform the following procedure.
    • [A] to [I]: 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.
22. Drive the vehicle at a speed between 75 and 100 km/h (47 and 62 mph) for 10 minutes or more [J].
    WARNING:

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

    HINT: 

    • Drive the vehicle while keeping the engine load as constant as possible.
    • The monitor item will change to Complete as the Catalyst Efficiency monitor operates.
23. Enter the following menus: Powertrain / Engine / Trouble Codes [K].
24. Check if any DTCs are stored.

    HINT: 

    If the monitor item does not change to Complete, and no DTCs are stored, extend the driving time.

25. Enter the following menus: Powertrain / Engine / Utility / All Readiness.
26. Input the DTC: P0420-00 or P0430-00.
27. 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 has a malfunction.
    • [A] to [K]: 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.
