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.

        *a Retainer
        B004ANI Pull

        Disconnect the fuel suction tube sub-assembly from the charcoal canister assembly.


        1. Pinch the retainer to detach the lock claw and pull it.

          Note


          • Remove any dirt or foreign matter on the tube connector before performing this work.

          • Do not allow any scratches or foreign matter to get on the parts when disconnecting them as the tube connector has an O-ring that seals the pipe (charcoal canister assembly).

          • Perform this work by hand. Do not use any tools.

          • Do not forcibly bend, twist or turn the fuel suction tube sub-assembly.

          • Protect the disconnected parts by covering them with plastic bags after disconnecting the fuel suction tube sub-assembly.

          • If the tube connector and pipe (charcoal canister assembly) are stuck, push and pull to release them.
