CONNECT CABLE TO NEGATIVE BATTERY TERMINAL
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.
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.
When no DTCs are output, the air bleeding is completed.
If any DTCs are output, proceed to the next step.
Clear the DTCs Click here.
Repeat steps *1 to *3.
Enter the following menus: Powertrain / Engine and ECT / DTC.

ADD ENGINE COOLANT
Затяните пробку сливного крана радиатора вручную.
Долейте в наливную горловину радиатора фирменную жидкость с увеличенным сроком замены (SLLC) от компании Тойота.

Tech Tips
Автомобили Toyota первоначально заправляются охлаждающей жидкостью TOYOTA SLLC на заводе. Во избежание повреждения системы охлаждения двигателя или других технических проблем разрешается использовать только охлаждающую жидкость "TOYOTA Super Long Life Coolant" или аналогичную высококачественную охлаждающую жидкость на основе этиленгликоля (а не на силикатной, аминовой, нитритной или борнокислой основе), изготовленную по гибридной технологии органических кислот с длительным сроком годности (охлаждающая жидкость, изготовленная по гибридной технологии органических кислот, состоит из низкофосфатных соединений и органических кислот).
Note
Никогда не используйте воду вместо охлаждающей жидкости.
| *1 | Пробка выпуска воздуха |
|
Линия B |
Снимите пробку радиатора и пробку выпуска воздуха, и долейте охлаждающую жидкость до отметки B на расширительном бачке.
Несколько раз сожмите рукой входной и выходной патрубки радиатора, а затем проверьте уровень охлаждающей жидкости.
Если уровень охлаждающей жидкости недостаточен, добавьте жидкость.
Установите пробку радиатора и пробку выпуска воздуха, а затем надлежащим образом прогрейте двигатель.
Выпустите воздух из системы охлаждения.
Note
Перед запуском двигателя установите выключатель системы кондиционирования в положение OFF (ВЫКЛ).
Установите температуру кондиционера на уровень MAX (HOT).
Установите вентилятор кондиционера в режим Lo.
Прогревайте двигатель, пока не откроется термостат. Когда термостат откроется, обеспечьте циркуляцию охлаждающей жидкости в течение нескольких минут.
CAUTION:
При сжатии патрубка радиатора:Работайте в защитных перчатках.
Будьте осторожны: патрубки радиатора горячие.
Не прикасайтесь к вентилятору радиатора.
Tech Tips
Момент открывания термостата можно определить, сжав входной патрубок радиатора рукой и отметив вибрации, когда охлаждающая жидкость двигателя начнет поступать в шланг.
После прогрева двигателя дайте ему поработать не менее 7 мин в следующем цикле: на частоте 3000 об/мин в течение 5 с, а затем на частоте вращения холостого хода в течение 45 с (этот цикл следует повторить, по крайней мере, 8 раз).
Несколько раз сожмите рукой входной и выходной патрубки радиатора, чтобы удалить воздух из системы.
CAUTION:
При сжатии патрубка радиатора:Работайте в защитных перчатках.
Будьте осторожны: патрубки радиатора горячие.
Не прикасайтесь к вентилятору радиатора.
После охлаждения двигателя убедитесь, что уровень охлаждающей жидкости находится между отметками "LOW" и "FULL".
Если уровень охлаждающей жидкости мал, долейте жидкость до отметки FULL на расширительном бачке.
INSPECT FOR COOLANT LEAK
Снимите пробку расширительного бачка радиатора.
CAUTION:
Во избежание ожогов не снимайте пробку расширительного бачка радиатора, пока двигатель и радиатор не остынут. Тепловое расширение вызывает выброс из радиатора горячей охлаждающей жидкости и пара.
Заполните радиатор охлаждающей жидкостью, а затем подсоедините приспособление для опрессовки системы охлаждения и проверки пробки радиатора.
Прогрейте двигатель.
С помощью этого приспособления создайте давление 118 кПа (1,2 кгс/см2, 17 фунта на кв. дюйм) и убедитесь, что давление не падает.
Если давление снижается, проверьте на наличие утечек шланги, радиатор и насос системы охлаждения.
Если нет признаков наружной утечки охлаждающей жидкости, проверьте сердцевину отопителя, блок цилиндров и головку блока цилиндров.
Установите пробку расширительного бачка радиатора.
INSPECT FOR OIL LEAK
Warm up the engine and check for an engine oil leak.
INSPECT FOR FUEL LEAK
Tech Tips
Using the intelligent tester to perform Active Tests allow relays, VSVs, actuators and other items to be operated without removing any parts. This non-intrusive functional inspection can be very useful because intermittent operation may be discovered before parts or wiring is disturbed. Performing Active Tests early in troubleshooting is one way to save diagnostic time. Data List information can be displayed while performing Active Tests.
Perform Active Test.
Connect the intelligent tester to the DLC3.
Turn the ignition switch to ON.
Start the engine.
Turn the intelligent tester on.
Enter the following menus: Powertrain / Engine and ECT/ Active Test.
Perform the Active Test.
| Tester Display | Test Part | Control Range | Diagnostic Notes |
|---|---|---|---|
| Test the Fuel Leak | Pressurizes common rail internal fuel pressure, and checks for fuel leaks | Stop/Start | Performs inspection of the high pressure fuel system.

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.
