ТОПЛИВНАЯ СИСТЕМА ПРОВЕРКА БЕЗ СНЯТИЯ С АВТОМОБИЛЯ

PROCEDURE

1. FUEL PRESSURE

   
   

   1. Read Data List

      Note

      In the table below, the values listed under "Normal Condition" are reference values. Do not depend solely on these reference values when deciding whether a part is faulty or not.

      Tech Tips

      Using the GTS to read the Data List allows the values or states of switches, sensors, actuators and other items to be read without removing any parts. This non-intrusive inspection can be very useful because intermittent conditions or signals may be discovered before parts or wiring is disturbed. Reading the Data List information early in troubleshooting is one way to save diagnostic time.

      
      

      1. Warm up the engine.

      2. Turn the ignition switch off.

      3. Connect the GTS to the DLC3.

      4. Turn the ignition switch to ON.

      5. Turn the GTS on.

      6. Enter the following menus: Powertrain / Engine and ECT / Data List.

      7. Read the Data List.

         Tester Display	Measurement Item/Range	Normal Condition
         Fuel Press	Fuel pressure/ Min.: 0 kPa, Max.: 655350 kPa	Idling: 27000 to 45000 kPa
         Target Common Rail Pressure	Target common rail pressure/ Min.: 0 kPa, Max.: 655350 kPa	32000 to 200000 kPa when engine running

2. INSPECT FOR FUEL LEAK

   
   

   1. Connect the GTS to the DLC3.

   2. Turn the ignition switch to ON.

   3. Turn the GTS on.

   4. Enter the following menus: Powertrain / Engine and ECT / Active Test.

      
      Powertrain > Engine and ECT > Active Test

      Tester Display
      Test the Fuel Leak

   5. Perform the Active Test.

      Tester Display	Measurement Item	Control Range	Diagnostic Note
      Test the Fuel Leak	Pressurize the common rail interior and check for fuel leaks	Stop/Start	Fuel pressure inside common rail pressurized to specified value and engine speed increased to 2000 rpm when ON is selected. Above conditions preserved while test is ON. Tech Tips If this Active Test is performed when the engine is cold, combustion may become unstable. However, this is not a malfunction. It is only necessary to confirm that the pressure rises to the target pressure and that there are no fuel leaks.
