Note. The Evaporative System Check (Automatic Mode) consists of 9 steps performed automatically by the Techstream. It takes a maximum of approximately 40 minutes. Do not perform the Evaporative System Check when the fuel tank is higher 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 higher, a large amount of vapor forms and any check results become inaccurate. When performing the Evaporative System Check, keep the fuel temperature less than 35°C (95°F).

Confirm that the difference between Vapor Pressure Pump and MAP are 3.5 kPa(gauge) [26.25 mmHg(gauge)] or less. NEXT --> END
6. GO TO DTC CHART. Refer to «DIAGNOSTIC TROUBLE CODE CHART»(ref-553305-S14271064972013051700000)

Refer to EVAP system. Refer to MONITOR RESULT .

Note. The Evaporative System Check (Automatic Mode) consists of 9 steps performed automatically by the Techstream. It takes a maximum of approximately 40 minutes. Do not perform the Evaporative System Check when the fuel tank is higher 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 higher, a large amount of vapor forms and any check results become inaccurate. When performing the Evaporative System Check, keep the fuel temperature less than 35°C (95°F).

1. Connect the Techstream to the DLC3.
2. Turn the power switch on (IG) and turn the Techstream on.
3. Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
4. Turn the power switch off and wait for at least 30 seconds.
5. Turn the power switch on (IG) and turn the Techstream on.
6. Enter the following menus: Powertrain / Engine and ECT / Utility / Evaporative System Check / Automatic Mode.
7. After the Evaporative System Check is completed, check for All Readiness by entering the following menus: Powertrain / Engine and ECT / Utility / All Readiness.
8. Input the DTC: P1420 or P1421.
9. 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.
10. If the judgment result is INCOMPLETE or N/A and no pending DTC is output, perform a universal trip and check for permanent DTCs. Refer to «DTC CHECK / CLEAR»(ref-553305-S22976237422013051700000) . HINT: If a permanent DTC is output, the system is malfunctioning. If no permanent DTC is output, the system is normal.
