HINT: 

After a repair, check Monitor Status by performing the Key-Off Monitor Confirmation and Purge Flow Monitor Confirmation described below.

  1. KEY-OFF MONITOR CONFIRMATION 
    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 more than 90% full because the cut-off valve may be closed, making the fuel tank leak check unavailable.
    • Do not start 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).
    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 at least 30 seconds.
    6. Turn the power switch on (IG).
    7. Turn the Techstream on.
    8. Enter the following menus: Powertrain / Engine / Utility / Evaporative System Check / Automatic Mode.
    9. After the "Evaporative System Check" is completed, check for All Readiness by entering the following menus: Powertrain / Engine / Utility / All Readiness.
    10. Input the DTC: P043E00, P043F00, P04417E, P04417F, P045011, P045015, P04502F, P142000, P142100, P142200, P142300, P145011, P145015, P14502A, P14502F, P24007E, P24007F, P24187E, P24187F, P24507E or P24517F.
