  19. BLEED AIR FROM FUEL SYSTEM


    1. A0157KL

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

      Note


      • The maximum hand pump pumping speed is 2 strokes per second.

      • 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 engine switch off.

    4. Connect the intelligent tester to the DLC3.

    5. Turn the ignition switch ON (IG) and turn the intelligent tester on.

    6. Clear the DTCs Click here.

    7. Start the engine.*1

    8. A0159RJE19

      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 5th time.

      A015AR0E04

      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 Click here.

      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.

      3. Start the engine.

      4. Turn the intelligent tester ON.

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

      6. Perform the Active Test.

        Tester Display Test Detail Control Range Diagnostic Note
