ВОЗДУШНЫЙ НАГНЕТАТЕЛЬ (для моделей с вспомогательной системой подачи воздуха в нейтрализатор) ПРОВЕРКА БЕЗ СНЯТИЯ С АВТОМОБИЛЯ

PROCEDURE


  1. INSPECT AIR PUMP ASSEMBLY


    1. Start the engine and warm it up.

    2. Turn the engine switch off.

    3. B001X4N

      Connect the 400 A probe of an ammeter to the (+) wire of the air pump.

    4. Connect the GTS to the DLC3.

    5. Turn the engine switch on (IG) and turn the GTS on.

    6. Enter the following menus: Powertrain / Engine and ECT / Utility / Secondary Air Injection Check / Manual Mode / AIR PUMP 1: ON, ASV1: OPEN, AIR PUMP 2: ON, ASV2: OPEN.

      Tech Tips

      When Manual Mode is selected, the GTS initialization (atmospheric pressure measurement) is performed automatically. The initialization takes 10 seconds. After the initialization, AIR PUMP and ASV operation can be selected.

    7. Measure the current while the air pump is turning.

      Standard Current
      Condition Specified Condition
      20°C (68°F) 10 to 40 A

    8. Turn the engine switch off.

      Note


      • This Air Injection Check only allows technicians to operate the AIR system for a maximum of 5 seconds.

        Furthermore, the check can only be performed up to 4 times per trip. If the test is repeated, intervals of at least 30 seconds are required between checks.

        While AIR system operation using the GTS is prohibited, the GTS display indicates the prohibition (WAIT or ERROR).

        If an ERROR is displayed on the GTS during the test, stop the engine for 10 minutes, and then try again.

      • Performing the Air Injection Check repeatedly may cause damage to the AIR system. If necessary, leave an interval of several minutes between Air Injection Check operations to prevent the system from overheating.

      • When performing the Air Injection Check operation after the battery cable has been reconnected, wait for 7 minutes with the engine switch turned on (IG) or the engine running.

      • Turn the engine switch off when the Air Injection Check operation finishes.
