FUEL FILTER INSTALLATION


  1. INSTALL FUEL FILTER ELEMENT ASSEMBLY


    1. A003HXEE01

      Install 2 new O-rings to a new fuel filter element and a new O-ring to the fuel filter case.

    2. Install the fuel filter element to the fuel filter case.

    3. A003CW6

      Align the alignment mark on the fuel filter cap with the 2 alignment marks on the fuel filter case.

    4. A003BGVE02

      Turn the fastener nut until a 'click' sound is heard.

      Tech Tips

      As the marks near alignment, it will become increasingly difficult to tighten the fastener nut by hand. If necessary, use a screwdriver as a lever to turn the fastener nut.

    5. except Cold Area Specification Vehicles:

      Connect the 2 fuel hoses.

    6. for Cold Area Specification Vehicles:

      Connect the 4 fuel hoses.

    7. Connect the level warning switch connector.

  2. RESET FUEL SYSTEM WARNING LIGHT


    1. Turn the ignition switch to ON.

    2. A003G8I

      After turning the ignition switch to ON, connect the clogging switch connector within 3 to 60 seconds.

    3. Check that the combination meter's fuel system warning light turns off.

  3. INSTALL FUEL TANK CAP ASSEMBLY

  4. BLEED AIR FROM FUEL SYSTEM


    1. A003AY1E01

      Using the hand pump mounted on the fuel filter cap, bleed air from the fuel system. Continue pumping until the pump resistance increases.

      Note


      • Hand pump pumping speed: Max. 2 strokes/ sec.

      • The hand pump must be pushed with a full stroke during pumping.

      • When the fuel pressure at the supply pump inlet port reaches a saturated pressure, the hand pump resistance increases.

      • If pumping is interrupted during the air bleeding process, fuel in the fuel line may return to the fuel tank. Continue pumping until the hand pump resistance increases.

      • If the hand pump resistance does not increase despite consecutively pumping 200 times or more, there may be a fuel leak between the fuel tank and fuel filter, the hand pump may be malfunctioning, or the vehicle may have run out of fuel.

      • If air bleeding using the hand pump is incomplete, the common rail pressure does not rise to the pressure range necessary for normal use, and the engine cannot be started.

    2. Check if the engine starts.

      Note


      • Even if air bleeding using the hand pump has been completed, the starter may need to be cranked for 10 seconds or more to start the engine.

      • Do not crank the engine continuously for more than 20 seconds. The battery may be discharged.

      • Use a fully-charged battery.


      1. When the engine can be started, proceed to the next step.

      2. If the engine cannot be started, bleed air again using the hand pump until the hand pump resistance increases (refer to the procedures above). Then start the engine.

    3. Turn the ignition switch off.

    4. Connect the GTS to the DLC3.

    5. Turn the ignition switch to ON and turn the GTS on.

    6. Clear the DTCs.


    7. Start the engine.*1

    8. A003BQAE03

      Enter the following menus: Powertrain / Engine and ECT / Active Test / Test the Fuel Leak.*2

    9. Perform the following test 5 times with on/off intervals of 10 seconds: Active Test / Test the Fuel Leak.*3

    10. Allow the engine to idle for 3 minutes or more after performing the Active Test for the fifth time.

      A003HPJE05

      Tech Tips

      When the Active Test "Test the Fuel Leak" is used to change the pump control mode, the actual fuel pressure inside the common rail drops below the target fuel pressure when the Active Test is off, but this is normal and does not indicate a pump malfunction.

    11. Enter the following menus: Powertrain / Engine and ECT / DTC.

    12. Read Current DTCs.

    13. Clear the DTCs.


      Tech Tips

      It is necessary to clear the DTCs as DTC P1604 or P1605 may be stored when air is bled from the fuel system after replacing or repairing fuel system parts.

    14. Repeat steps *1 to *3.

    15. Enter the following menus: Powertrain / Engine and ECT / DTC.

    16. Read Current DTCs.

      OK
      No DTCs are output.

  5. INSPECT FOR FUEL LEAK


    1. Perform the Active Test.


      1. Connect the GTS to the DLC3.

      2. Turn the ignition switch to ON.

      3. Turn the GTS on.

      4. Enter the following menus: Powertrain / Engine and ECT / Active Test.

      5. Perform the Active Test.

        • Fuel pressure inside common rail increased to specified value and engine speed increased to 2000 rpm when Active Test is performed

        • Above conditions preserved while Active Test is being performed
