Note
When disconnecting the cable, some systems need to be initialized after the cable is reconnected Click here.
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.
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.
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
| *a | Reference (Active Test Operation) |
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.

ADD ENGINE COOLANT
Tighten the cylinder block drain cock plug.
Tighten the radiator drain cock plug by hand.
Fill the radiator with TOYOTA Super Long Life Coolant (SLLC) to the reservoir tank's B line.
| Standard capacity | ||||||
|---|---|---|---|---|---|---|
|
Tech Tips
TOYOTA vehicles are filled with TOYOTA SLLC at the factory. In order to avoid damage to the engine cooling system and other technical problems, only use TOYOTA SLLC or similar high quality ethylene glycol based non-silicate, non-amine, non-nitrite, non-borate coolant with long-life hybrid organic acid technology (coolant with long-life hybrid organic acid technology consists of a combination of low phosphates and organic acids).
Note
Never use water as a substitute for engine coolant.
Press the inlet and outlet radiator hoses several times by hand, and then check the level of the coolant.
If the coolant level drops below the B line, add TOYOTA SLLC to the B line.
Install the radiator reservoir cap.
Using a wrench, install the vent plug.
Bleed air from the cooling system.
Warm up the engine until the thermostat opens. While the thermostat is open, circulate the coolant for several minutes.
Tech Tips
The thermostat open timing can be confirmed by pressing the inlet radiator hose by hand, and checking when the engine coolant starts to flow inside the hose.
Maintain the engine speed at 2500 to 3000 rpm.
Press the inlet and outlet radiator hoses several times by hand to bleed air.
CAUTION:
When pressing the radiator hoses:
Wear protective gloves.
Be careful as the radiator hoses are hot.
Keep your hands away from the radiator fan.
Stop the engine and wait until the coolant cools down to ambient temperature.
CAUTION:
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.
After the coolant cools down, check that the coolant level is at the F line.
If the coolant level is below the F line, add TOYOTA SLLC to the F line.
BLEED AIR FROM POWER STEERING SYSTEM
Check the fluid level.
Jack up the front of the vehicle and support it with stands.
Turn the steering wheel.
With the engine stopped, turn the steering wheel slowly from lock to lock several times.
Lower the vehicle.
Start the engine. Run the engine at idle for a few minutes.
Turn the steering wheel.
With the engine idling, turn the steering wheel to the left or right full lock position and hold it there for 2 to 3 seconds. Then turn the steering wheel to the opposite full lock position and hold it there for 2 to 3 seconds.
Repeat the step above several times.
Stop the engine.
Check for foaming or emulsification. If the system has to be bled twice because of forming or emulsification, check for fluid leaks in the system.
Check the fluid level.
INSPECT FOR POWER STEERING FLUID LEVEL
Keep the vehicle level.
With the engine stopped, check the power steering fluid level in the oil reservoir. If necessary, add power steering fluid.
| Power steering fluid (for TMT made) |
|---|
| "TEXAMATIC 1888" or equivalent |
| (for TSAM made) |
| "TEXAMATIC 1322S" or equivalent |
Tech Tips
If the fluid is hot, check that the fluid level is within the HOT range on the oil reservoir. If the fluid is cold, check that the fluid level is within the COLD range.
Start the engine and run it at idle.
Turn the steering wheel to the left or right full lock position, and then the wheel to the opposite full lock position. Repeat several times to raise fluid temperature.
| Standard fluid temperature |
|---|
| 75 to 80°C (167 to 176°F) |
Check for foaming or emulsification. If foaming or emulsification is identified, bleed air from the power steering system.
With the engine idling, measure the fluid level in the oil reservoir.
Stop the engine.
Wait a few minutes and remeasure the fluid level in the oil reservoir.
| Maximum fluid level increase |
|---|
| 5 mm (0.20 in.) |
If a problem is found, bleed air from the power steering system.
Check the fluid level.

INSPECT FOR OIL LEAK
Start the engine. Make sure that there are no oil leaks from the areas that were worked on.
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 a 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.
INSPECT FOR EXHAUST GAS LEAK
If gas is leaking, tighten the areas necessary to stop the leak. Replace damaged parts as necessary.
INSPECT FOR FUEL LEAK
Perform the Active Test.
Connect the intelligent tester to the DLC3.
Turn the ignition switch to ON.
Turn the intelligent tester on.
Enter the following menus: Powertrain / Engine and ECT / Active Test.
Perform the Active Test.
| Intelligent Tester Display | Test Part | Control Range | Diagnostic Note |
|---|---|---|---|
| Test the Fuel Leak | Pressurize common rail interior and check for fuel leaks | Stop/Start |
|
INSPECT ENGINE OIL LEVEL
Warm up the engine, stop the engine and wait 5 minutes. The engine oil level should be between the dipstick low level mark and full level mark.
If low, check for leakage and add oil up to the full level mark.
Note
Do not fill engine oil above the full level mark.
