.
CONFIRMATION DRIVING PATTERN
Connect the Techstream to the DLC3.
1.
Turn the ignition switch to ON and turn the Techstream on.
2.
Clear the DTCs (even if no DTCs are stored, perform the clear DTC operation).
3.
Turn the ignition switch off and wait for at least 30 seconds.
4.
Turn the ignition switch to ON and turn the Techstream on [A].
5.
Start the engine and wait 15 minutes or more [B].
6.
Enter the following menus: Powertrain / Engine and ECT / Trouble Codes [C].
7.
Read the pending DTC.
HINT:
If a pending DTC is output, the system is malfunctioning.
If a pending DTC is not output, perform the following procedure.
8.
Enter the following menus: Powertrain / Engine and ECT / Utility / All Readiness.
9.
Input the DTC: P0441.
10.
Check the DTC judgment result.

NOTICE:
Do not perform the Evaporative System Check when the fuel tank is more than 90% full because the
cut-off valve may be closed, making the fuel tank leak check unavailable.
Turn the ignition switch to ON and turn the Techstream on.
12.
Clear the DTCs (even if no DTCs are stored, perform the clear DTC operation).
13.
Turn the ignition switch off and wait for at least 30 seconds.
14.
Turn the ignition switch to ON
15.
Turn the Techstream on [D].
16.
Enter the following menus: Powertrain / Engine and ECT / Utility / Evaporative System Check / Automatic Mode.
17.
After the "Evaporative System Check" is completed, check All Readiness by entering the following menus:
Powertrain / Engine and ECT / Utility / All Readiness.
18.
Input the DTC: P0441.
19.
Check the DTC judgment result [E].

INCOMPLETE
DTC judgment not completed
Perform driving pattern after confirming DTC enabling conditions
N/A
Unable to perform DTC judgment
HINT:
If the judgment result shows ABNORMAL, the system has a malfunction.
20.
If the test result is INCOMPLETE or N/A and no pending DTC is output, perform a universal trip and check for
permanent DTCs
.
HINT:
If a permanent DTC is output, the system is malfunctioning.
If no permanent DTC is output, the system is normal.
