1. Connect the Techstream to the DLC3.
2. Turn the power 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 power switch off and wait for 30 seconds.
6. Turn the power switch on (IG) and turn the Techstream on.
7. Put the engine in inspection mode (maintenance mode).
8. Start the engine, and warm it up until the engine coolant temperature reaches 75°C (167°F) or higher [A].
9. On the Techstream, enter the following menus to check the fuel-cut status: Powertrain / Engine and ECT / Data List / Primary / Idle Fuel Cut.
10. Drive the vehicle at between 75 and 120 km/h (47 and 75 mph) for at least 10 minutes [B].
    CAUTION: When performing the confirmation driving pattern, obey all speed limits and traffic laws.
11. Move the shift lever in B [C].
12. Accelerate the vehicle to 75 km/h (47 mph) or more by depressing the accelerator pedal for at least 10 seconds [D].
13. 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].
    NOTE: Fuel-cut control is executed when the accelerator pedal is released while the vehicle is moving at 35 km/h (22 mph) or slower (Fuel-cut control is prohibited when the engine speed decreases to 1000 rpm or lower).
14. Allow the vehicle to decelerate until the vehicle speed decreases to less than 10 km/h (6 mph).
15. Repeat steps [C] through [E] above at least 3 times in one driving cycle.
16. Enter the following menus: Powertrain / Engine and ECT / Trouble Codes [F].
17. Read the pending DTCs.
    • If a pending DTC is output, the system is malfunctioning.
    • If a pending DTC is not output, perform the following procedure.
18. Enter the following menus: Powertrain / Engine and ECT / Utility / All Readiness.
19. Input the DTC: P2195 or P2196.
20. Check the DTC judgment result.
    JUDGMENT RESULT
    
    

    TECHSTREAM DISPLY	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's memory limit

    • 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 UNKNOWN, perform steps [B] through [E].
21. If no pending DTC is output, perform a universal trip and check for permanent DTCs.
    • If a permanent DTC is output, the system is malfunctioning.
    • If no permanent DTC is output, the system is normal.
