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.
Read Current DTCs.

INSPECT ENGINE OIL LEVEL
Warm up the engine, stop the engine and wait 5 minutes. The oil level should be between the dipstick's low and full level marks.
If the oil level is low, check for leakage and add oil up to the full level mark.
Note
Do not fill engine oil above the full level mark.
INSPECT FOR FUEL LEAK
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.
INSPECT FOR ENGINE OIL LEAK
INSPECT FOR COOLANT LEAK
Note
Do not remove the radiator reservoir cap while the engine and radiator are still hot. Pressurized, hot engine coolant and steam may be released and cause serious burns.
Fill the radiator with coolant and attach a radiator cap tester to the radiator reservoir.
Warm up the engine.
Using the radiator cap tester, increase the pressure inside the radiator to 118 kPa (1.2 kgf/cm2,17.1 psi), and check that the pressure does not drop.
If the pressure drops, check the hoses, radiator and water pump for leaks.
If no external leaks are found, check the cylinder block and head.
