CANISTER ON-VEHICLE INSPECTION

PROCEDURE


  1. INSPECT CANISTER (CHARCOAL CANISTER ASSEMBLY)


    1. Visually check the canister (charcoal canister assembly).


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

        If cracks or damage are found, replace the canister (charcoal canister assembly).

    2. Check canister (charcoal canister assembly) operation under positive pressure.

        B003Z8F Pull Off

        Disengage the 2 claws, pull out the retainer and pull off the vent line hose.

        Note


        • Remove any dirt or foreign matter on the vent line hose before performing this work.

        • Do not allow any scratches or foreign matter to get on the parts when disconnecting them as the vent line hose has an O-ring that seals the pipe.

        • Only pull off the vent line hose by hand.

        • Do not forcibly bend, twist or turn the vent line hose.

      2. Close the vent line hose using a hose plug or a similar part.

        *a Test Hose
        *b Air

        Connect a test hose to the canister (charcoal canister assembly).

      4. Blow 5 kPa (0.1 kgf/cm2, 0.7 psi) of air into the test hose and check that air passes through the canister (charcoal canister assembly).

        If the result is not as specified, replace the canister (charcoal canister assembly).

    3. Check canister (charcoal canister assembly) operation under vacuum.

        Disengage the 2 claws, pull out the retainer and pull off the vent line hose.

        Note


        • Remove any dirt or foreign matter on the vent line hose before performing this work.

        • Do not allow any scratches or foreign matter to get on the parts when disconnecting them as the vent line hose has an O-ring that seals the pipe.

        • Only pull off the vent line hose by hand.

        • Do not forcibly bend, twist or turn the vent line hose.

      2. Close the vent line hose using a hose plug or a similar part.

      3. A00270CC01
        *a Test Hose

        Connect a test hose to the canister (charcoal canister 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.

        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, replace the canister (charcoal canister assembly).

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

        B003ZIE Pull Out
        B003Z8F Pull Off

        Disengage the 2 claws, pull out the retainer and pull off the vent line hose.

        • Remove any dirt or foreign matter on the vent line hose before performing this work.

        • Do not allow any scratches or foreign matter to get on the parts when disconnecting them as the vent line hose has an O-ring that seals the pipe.

        • Only pull off the vent line hose by hand.

        • Do not forcibly bend, twist or turn the vent line hose.

      2. Close the vent line hose using a hose plug or similar part.

      3. A00270CC01
        *a Test Hose

        Connect a test hose to the canister (charcoal canister 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.

        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.

    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.

        *a Test Hose

        Connect a test hose to the canister (charcoal canister 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 VSV for Evap Control.


        Powertrain > Engine > Active Test
        Tester Display
        Activate the VSV for Evap Control

      8. Check that the vacuum pump indicator does not move 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.
