1. Connect the Techstream to the DLC3.
2. Turn the ignition switch to ON.
3. Turn the Techstream on.
4. Clear the DTCs. Refer to DTC CHECK / CLEAR .
5. Turn the ignition switch off.
6. Turn the ignition switch to ON and turn the Techstream on.
7. Start the engine, and warm it up until the ECT reaches 75°C (167°F) or more (Step "A").
8. On 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 between 38 and 75 mph (60 and 120 km/h) for at least 10 minutes (Step "B").
   WARNING:

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

10. Shift the transmission to 2nd gear (Step "C").
11. Accelerate the vehicle to 40 mph (64 km/h) or more by depressing the accelerator pedal for at least 10 seconds (Step "D").
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 (Step "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 1000 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 / Utility / All Readiness.
16. Input the DTC: P2195 or P2196.
17. Check the DTC judgment result [F].

    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
    UNKNOWN	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 ABNORMAL, the system has a malfunction.
    • If the judgment result shows INCOMPLETE or UNKNOWN, perform steps "B" through "F".
18. If the test result is UNKNOWN, enter the following menus: Powertrain / Engine and ECT / Trouble Codes / Pending.
19. Read Pending DTCs.

    HINT: 

    If a pending DTC is output, the system is malfunctioning.
