1. CHECK FUEL PUMP OPERATION AND FOR FUEL LEAKS

  1. Connect the intelligent tester to the DLC3.

  1. Turn the engine switch on (IG).

    ПРИМЕЧАНИЕ:
    Do not start the engine.

  1. Push the intelligent tester main switch ON.

  1. Select the following menus: Powertrain / Engine / Active Test / Control the Fuel Pump /Speed.

  1. Check the fuel pump operation.

    1. Check for pressure in the fuel inlet tube from the fuel line. Check that the sound of fuel flowing in the fuel tank can be heard.
      If no sound can be heard, check the integration relay, fuel pump, ECM and wiring connector.

  1. Check for fuel leaks.

    1. Check that there are no fuel leaks anywhere on the system after performing maintenance.
      If there is a fuel leak, repair or replace parts as necessary.



2. CHECK FUEL PRESSURE

  1. Check that the battery positive voltage is above 12 V.

  1. Discharge the fuel system pressure (see page Нажмите здесь).

  1. Disconnect the cable from the negative (-) battery terminal.



  1. Disconnect the fuel pump main tube.



      A138140

    1. Remove the fuel pipe clamp.



      2. A138141E01

    2. Pinch the connector and pull the fuel tube.

      ПРЕДОСТЕРЕЖЕНИЕ:
      1. Always read the precautions (see page Нажмите здесь) before disconnecting the fuel tube connector (quick type A).
      2. The fuel tube may spray fuel as a result of pressure that remains in the tube. Do not allow fuel to be sprayed in the engine compartment.



  1. Install SST (pressure gauge) as shown in the illustration.


    A107220E04

    Специальный инструмент (SST):
    09268-31012   (09268-41500, 90467-13001, 95336-08070)
    09268-45014   (09268-41200, 09268-41220, 09268-41250)

  1. Wipe off any gasoline.

  1. Reconnect the cable to the negative (-) battery terminal.

  1. Operate the fuel pump.

    1. Connect the intelligent tester to the DLC3.

    2. Turn the engine switch on (IG).

      ПРИМЕЧАНИЕ:
      Do not start the engine.

    3. Push the intelligent tester main switch ON.

    4. Select the following menus: Powertrain / Engine / Active Test / Control the Fuel Pump /Speed.

  1. Measure the fuel pressure.

    Standard fuel pressure:
    196 to 588 kPa (2 to 6 kgf/cm2, 28 to 85 psi)

    If the fuel pressure is higher than the specification, replace the fuel pump (built into fuel tank).
    If the pressure is lower than the specification, check the fuel hoses, connections and fuel pump (built into fuel tank).

  1. Connect the intelligent tester to the DLC3.

  1. Start the engine.

  1. Measure the fuel pressure at idle.

    Standard fuel pressure:
    196 to 588 kPa (2 to 6 kgf/cm2, 28 to 85 psi)

    If the pressure is not as specified, check the fuel pump and injectors.

  1. Stop the engine.

  1. Check that the fuel pressure remains as specified for 5 minutes after the engine has stopped.

    Standard fuel pressure:
    147 kPa (1.5 kgf/cm2, 21 psi) or more

    If the pressure is not as specified, check the fuel pump or injectors.

  1. After checking the fuel pressure, disconnect the cable from the negative (-) battery terminal and carefully remove SST and the fuel tube connector to prevent fuel from spilling.

  1. Reconnect the fuel pump main tube (see page Нажмите здесь).

  1. Check for fuel leaks.



3. PERFORM INITIALIZATION

  1. Perform initialization (see page Нажмите здесь).

    ПРИМЕЧАНИЕ:
    Certain systems need to be initialized after disconnecting and reconnecting the cable to the negative (-) battery terminal.
