Note. The Evaporative System Check (Automatic Mode) consists of 5 steps performed automatically by the Techstream. It takes a maximum of approximately 18 minutes. 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. Do not run the engine during this operation. When the temperature of the fuel is 35°C (95°F) or more, a large amount of vapor forms and any check results become inaccurate. When performing the Evaporative System Check, keep the fuel temperature below 35°C (95°F).

1. Connect the Techstream to the DLC3.
2. Turn the ignition switch to ON and turn the Techstream on.
3. Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure). Refer to «DTC CHECK / CLEAR»(ref-428881-S23178403412011101200000) .
4. Turn the ignition switch off and wait for 30 seconds.
5. Turn the ignition switch to ON and turn the Techstream on.
6. Enter the following menus: Powertrain / Engine / Utility / Evaporative System Check / Automatic Mode [A].
7. After the Evaporative System Check is completed, check for All Readiness by entering the following menus: Powertrain / Engine / Trouble Codes / Pending.
8. Read the Pending DTCs [B].
9. If a pending DTC is output, the system is malfunctioning. HINT: If a pending DTC is not output, perform the following procedure.
10. Enter the following menus: Powertrain / Engine / Utility / All readiness.
11. Input the DTC: P043E, P043F, P2401, P2402 or P2419.
12. 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 UNKNOWN Unable to perform DTC judgment Number of DTCs which do not fulfill DTC preconditions has reached ECU's memory limit HINT: If the judgment result shows ABNORMAL, the system has a malfunction. If the judgment result shows NORMAL, the system is normal. If the judgment result shows INCOMPLETE or UNKNOWN, perform step [A] again.
13. Enter the following menus: Powertrain / Engine / Utility / All Readiness.
14. Check the judgment result. HINT: If the judgment result shows ABNORMAL, the system has a malfunction. If the judgment result shows NORMAL, the system is normal.
15. If the test result is INCOMPLETE or UNKNOWN and no pending DTC is output, perform a universal trip and check for permanent DTCs. Refer to «DTC CHECK / CLEAR»(ref-428881-S23178403412011101200000) . HINT: If a permanent DTC is output, the system is malfunctioning. If no permanent DTC is output, the system is normal.
