Install the support bracket with the bolt.
INSTALL NO. 2 NOZZLE LEAKAGE PIPE ASSEMBLY
Temporarily install the leakage pipe with the 3 bolts.
Temporarily install a new gasket with the check valve.
Tighten the 3 bolts and check valve.
Connect the 3 fuel hoses.
INSTALL NO. 4 INJECTION PIPE SUB-ASSEMBLY
Note
When replacing the injector, also replace the injection pipe.
Keep the joints of the injection pipe clean.
Temporarily install the No. 4 injection pipe with the union nuts.
Install new injection pipe clamp with the bolt.
Note
Make sure that the inner-rubbers of the injection pipe fit inside the clamp.
When installing the pipe, check that the inner rubbers and the clamp are in their proper positions.
Using a 17 mm union nut wrench, tighten the injection pipe union nuts on the common rail side.
Tech Tips
Use a torque wrench with a fulcrum length of 30 cm (11.81 in.). If using a torque wrench with a length that is not 30 cm, calculate the torque specification for the torque wrench and union nut wrench based on the "without SST" torque specification Click here.
Make sure union nut wrench and wrench are connected in a straight line.

INSTALL OIL DIPSTICK GUIDE
Install a new O-ring to the guide.
Apply a small amount of clean engine oil to the O-ring.
Install the guide with the bolt.
Install the injection pipe clamp with the bolt.
INSTALL MANIFOLD STAY
Install the stay with the 2 bolts.
Connect the 3 vacuum hoses to the 2 VSV.
BLEED AIR FROM FUEL SYSTEM
Using the hand pump mounted on the fuel filter cap, bleed the 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.
Start the engine.
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.
When the engine can be started, proceed to the next step.
If the engine cannot be started, bleed the air again using the hand pump until the hand pump resistance increases (refer to the procedures above). Then start the engine.
Turn the ignition switch off.
Connect the intelligent tester to the DLC3.
Turn the ignition switch to ON and turn the intelligent tester on.
Clear the DTCs Click here.
Start the engine.*1
Enter the following menus: Powertrain / Engine and ECT / Active Test / Test the Fuel Leak.*2
Perform the following test 5 times with on/off intervals of 10 seconds: Active Test / Test the Fuel Leak.*3
Allow the engine to idle for 3 minutes or more after performing the Active Test for the fifth time.
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.
Enter the following menus: Powertrain / Engine and ECT / DTC.
Read Current DTCs.
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.
Repeat steps *1 to *3.
Enter the following menus: Powertrain / Engine and ECT / DTC.

CONNECT CABLE TO NEGATIVE BATTERY TERMINAL
CHECK FOR FUEL LEAKS
CAUTION:
During Active Test mode, engine speed becomes high and combustion noise becomes loud, so pay attention.
During Active Test mode, fuel becomes high-pressured. Be extremely careful not to expose your eyes, hands, or body to escaped fuel.
Check that there are no leaks from any part of the fuel system when the engine is stopped. If there is fuel leakage, repair or replace parts as necessary.
Start the engine and check that there are no leaks from any part of the fuel system. If there is fuel leakage, repair or replace parts as necessary.
Disconnect the return hose from the common rail.
Start the engine and check for fuel leaks from the return pipe.
If there is fuel leakage, replace the common rail.
Connect the intelligent tester to the DLC3.
Start the engine and push the intelligent tester main switch on.
Select the Fuel Leak test from the Active Test mode on the intelligent tester.
If the intelligent tester is not available, fully depress the accelerator pedal quickly. Increase the engine speed to the maximum and maintain that speed for 2 seconds. Repeat this operation several times.
Check that there are no leaks from any part of the fuel system.
Note
A return pipe leakage of less than 10 cc (0.6 cu in.) per minute is acceptable.
If there is fuel leakage, repair or replace parts as necessary.
Reconnect the return hose to the common rail.
