CANISTER(w/o Canister Pump Module) ON-VEHICLE INSPECTION

PROCEDURE


  1. INSPECT CHARCOAL CANISTER ASSEMBLY


    1. Visually check the charcoal canister assembly for cracks or damage.

      If cracks or damage is found, replace the charcoal canister assembly.

    2. Check charcoal canister assembly operation under positive pressure.


      1. B006DZR

        Disconnect the fuel tank breather tube sub-assembly from the charcoal canister assembly.

      2. Close the fuel tank breather tube sub-assembly using a hose plug or a similar part.

      3. B006H0QC02
        *a Air
        *b Test Hose

        Connect a test hose to the fuel outlet valve assembly.

      4. Blow 8 kPa (0.1 kgf/cm2, 1.2 psi) of air into the test hose and check that air passes through the fuel outlet valve assembly.

        OK
        Air flow freely

        If the result is not as specified, inspect the fuel outlet valve assembly and charcoal canister assembly.

      5. Disconnect the test hose from the fuel outlet valve assembly.

      6. Connect the fuel tank breather tube sub-assembly to the charcoal canister assembly.

    3. B006DZR

      Check charcoal canister assembly operation under vacuum.


      1. Disconnect the fuel tank breather tube sub-assembly from the charcoal canister assembly.

        Click here

      2. Close the fuel tank breather tube sub-assembly using a hose plug or a similar part.

      3. B006BT9C03
        *a Test Hose

        Connect a test hose to the fuel outlet valve assembly.

      4. Connect a vacuum pump to the test hose.

      5. Using the vacuum pump, apply vacuum and check that the vacuum pump indicator does not move from its initial position.

        OK
        The indicator needle of the vacuum pump does not rise from its initial position.

        Tech Tips

        The vacuum pump indicator may move when applying vacuum. If the vacuum pump indicator quickly returns to its initial position, the canister (charcoal canister assembly) is operating normally.

        If the result is not as specified, inspect the fuel outlet valve assembly and charcoal canister assembly.

      6. Disconnect the vacuum pump from the test hose.

      7. Disconnect the test hose from the fuel outlet valve assembly.

      8. Connect the fuel tank breather tube sub-assembly to the charcoal canister assembly.

    4. B006DZR

      Check for clogs in the air filter (when not using the GTS).


      1. Disconnect the fuel tank breather tube sub-assembly from the charcoal canister assembly.

      2. Close the fuel tank breather tube sub-assembly using a hose plug or a similar part.

      3. B006BT9C03
        *a Test Hose

        Connect a test hose to the fuel outlet valve assembly.

      4. Connect a vacuum pump to the test hose.

      5. Start the engine.

      6. Warm up the engine.

      7. Idle the engine for 15 minutes and check that the vacuum pump indicator does not move from its initial position.

        OK
        The indicator needle of the vacuum pump does not rise from its initial position.

        Tech Tips

        The vacuum pump indicator may move when the purge valve (purge VSV) opens to vacuum. If the vacuum pump indicator quickly returns to its initial position, the canister (charcoal canister assembly) is operating normally.

      8. Disconnect the vacuum pump from the test hose.

      9. Disconnect the test hose from the fuel outlet valve assembly.

      10. Connect the fuel tank breather tube sub-assembly to the charcoal canister assembly.

        Click here

    5. Check for clogs in the air filter (when using the GTS).

      Tech Tips

      When performing an Active Test of the purge valve (purge VSV) using the GTS, it is not necessary to warm up and idle the engine for 15 minutes.


      1. B006DZR

        Disconnect the fuel tank breather tube sub-assembly from the charcoal canister assembly.

        Click here

      2. Close the fuel tank breather tube sub-assembly using a hose plug or a similar part.

      3. B006BT9C03
        *a Test Hose

        Connect a test hose to the fuel outlet valve assembly.

      4. Connect a vacuum pump to the test hose.

      5. Connect the GTS to the DLC3.

      6. Start the engine.

      7. Enter the following menus: Powertrain / Engine / Active Test / Activate the EVAP Purge VSV


        Powertrain > Engine > Active Test
        Tester Display
        Activate the EVAP Purge VSV
        OK
        The indicator needle of the vacuum pump does not rise from its initial position.

        Tech Tips


        • When the engine idling, perform the Active Test.

        • The vacuum pump indicator may move when the purge valve (purge VSV) opens to vacuum. If the vacuum pump indicator quickly returns to its initial position, the canister (charcoal canister assembly) is operating normally.

      8. Disconnect the vacuum pump from the test hose.

      9. Disconnect the test hose from the fuel outlet valve assembly.

      10. Connect the fuel tank breather tube sub-assembly to the charcoal canister assembly.
