1. Connect the Techstream to the DLC3.
2. Turn the ignition switch to ON.
3. Turn the Techstream on.
4. Clear the DTCs (even if no DTCs are stored, perform the clear DTC operation). Refer to DTC CHECK / CLEAR .
5. Turn the ignition switch off and wait for at least 30 seconds.
6. Turn the ignition switch to ON and turn the Techstream on.
7. Start the engine and warm it up until the engine coolant temperature reaches 75°C (167°F) or higher [A].
8. On the Techstream, enter the following menus to check the fuel-cut status: Powertrain / Engine and ECT / Data List / Idle Fuel Cut.
9. Drive the vehicle at a speed between 37 and 75 mph (60 and 120 km/h) for at least 10 minutes [B].
   WARNING:

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

10. Shift the transaxle to 2nd gear [C].
11. Accelerate the vehicle to 40 mph (64 km/h) or more by depressing the accelerator pedal for at least 10 seconds [D].
    WARNING:

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

12. Soon after performing step [D] above, release the accelerator pedal for at least 4 seconds without depressing the brake pedal in order to execute fuel-cut control [E].

    HINT: 

    Fuel-cut is performed when the following conditions are met:

    • Accelerator pedal is fully released.
    • Engine speed is 2500 rpm or more (fuel injection returns at 1500 rpm).
13. Allow the vehicle to decelerate until the vehicle speed decreases to less than 6 mph (10 km/h).
14. Repeat steps [C] through [E] above at least 3 times in one driving cycle.
15. Enter the following menus: Powertrain / Engine and ECT / Trouble Codes [F].
16. 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.
17. Enter the following menus: Powertrain / Engine and ECT / Utility / All Readiness.
18. Input the DTC: P2195 or P2196.
19. 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
    N/A	Unable to perform DTC judgment Number of DTCs which do not fulfill DTC preconditions has reached ECU memory limit

    HINT: 

    • If the judgment result shows NORMAL, the system is normal.
    • If the judgment result shows ABNORMAL, the system has a malfunction.
    • If the judgment result shows INCOMPLETE or N/A, perform steps [B] through [F] again.
20. If no pending DTC is output, perform a universal trip and check for permanent DTCs. Refer to DTC CHECK / CLEAR .

    HINT: 

    • If a permanent DTC is output, the system is malfunctioning.
    • If no permanent DTC is output, the system is normal.
