ECD SYSTEM (w/o EGR Cooler) DATA LIST / ACTIVE TEST


  1. READ DATA LIST

    Tech Tips

    Using the intelligent tester's Data List allows switch, sensor, actuator, and other item values to be read without removing any parts. Reading the Data List early in troubleshooting is one way to save time.

    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.


    1. Warm up the engine.

    2. Turn the ignition switch OFF.

    3. Connect the intelligent tester to the DLC3.

    4. Turn the ignition switch ON.

    5. Turn the intelligent tester ON.

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

      Tech Tips

      To display the entire Data List, press the pull down menu button next to Primary. Then select All Data.

    7. Read the Data List.

      Tech Tips

      Normal Condition: If no idling conditions are specified, the shift lever should be in the neutral position, and the A/C switch and all accessory switches should be OFF.

  2. PERFORM ACTIVE TEST

    Tech Tips

    Performing the intelligent tester's Active Test allows relay, VSV, actuator and other items to be operated without removing any parts. Performing the Active Test early in troubleshooting is one way to save time.

    The Data List can be displayed during the Active Test.


    1. Connect the intelligent tester to the DLC3.

    2. Turn the ignition switch ON.

    3. Turn the intelligent tester ON.

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

    5. Perform the Active Test.

      • Fuel pressure inside common rail pressurized to specified value and engine speed increased to 2,000 rpm when ON is selected

      Control the Cylinder#1 Fuel Cut Cut off fuel injection from No. 1 injector ON/OFF Fuel injection stopped while test is ON
      Control the Cylinder#2 Fuel Cut Cut off fuel injection from No. 2 injector ON/OFF As above
      Control the Cylinder#3 Fuel Cut Cut off fuel injection from No. 3 injector ON/OFF As above
      Control the Cylinder#4 Fuel Cut Cut off fuel injection from No. 4 injector ON/OFF As above
      Check the Cylinder Compression* Check the cylinder compression pressure ON/OFF Fuel injection stops in all cylinders.

    Tech Tips

    *: When cranking the engine, the Active Test measures the speed of each cylinder. In this Active Test, the fuel of all cylinders is cut when the engine is cranked for approximately 10 seconds.

    At this time, the speed of each cylinder is measured. If the speed of one cylinder is higher than the other cylinders, the compression pressure of that cylinder is determined to be lower than the other cylinders.


    1. Warm up the engine.

    2. Turn the ignition switch off.

    3. Connect the intelligent tester to the DLC3.

    4. Turn the ignition switch to ON and turn the tester on.

    5. Enter the following menus: Powertrain / Engine and ECT / Active Test / Check the Cylinder Compression.

      Tech Tips

      If the results are not displayed normally, select the display items from the Data List before performing the Active Test. Enter the following menus: Powertrain / Engine and ECT / Data List / Compression / Engine Speed of Cyl #1, Engine Speed of Cyl #2, Engine Speed of Cyl #3, Engine Speed of Cyl #4 and Av Engine Speed of All Cyl.

    6. While the engine is not running, press the RIGHT or LEFT button to change Check the Cylinder Compression to ON.

      Tech Tips

      After performing the above procedure, the Active Test Check the Cylinder Compression will start. Fuel injection for all cylinders is prohibited, and the engine speed measurement of each cylinder will enter standby mode.

    7. Crank the engine for about 10 seconds.

    8. Monitor the engine speed (Engine Speed of Cyl #1 to #4, Av Engine Speed of All Cyl) displayed on the tester.

      Tech Tips

      At first, the tester display will show the engine speed measurement of each cylinder to be extremely high. After approximately 10 seconds of engine cranking, the engine speed measurement of each cylinder will change to the actual engine speed.

      Note


      • After the Active Test Check the Cylinder Compression is turned on, it will automatically turn off after 255 seconds.

      • When the Check the Cylinder Compression test is off and the engine is cranked, the engine will start.

      • If the Check the Cylinder Compression test needs to be performed after it is turned on and performed once, press EXIT to return to the Active Test menu screen. Then perform the Check the Cylinder Compression test again.

      • Use a fully-charged battery.

  3. SYSTEM CHECK


    1. Activate the Pressure Discharge Valve Check

      Tech Tips


      • This is the procedure for troubleshooting fuel pressure control malfunctions and combustion problems.

      • Malfunctions can be determined by checking the fuel pressure when performing a fuel cut and operating the pressure discharge valve with the intelligent tester.

      • During "Pressure Discharge Valve Check", the intelligent tester measures the fuel pressure while the engine is running, after the engine is stopped, and after the pressure discharge valve operates.


      1. Connect the intelligent tester to the DLC3.

      2. Turn the ignition switch to ON.

      3. A01DVOT

        Turn the tester on.

        Note

        Confirm the following conditions:


        • Engine is idling.

        • Vehicle is stopped.

        • Fuel pressure is not extremely high (less than 100000 kPa).

        • Fuel pressure sensor is normal.

        • Battery voltage is more than 8 V.

      4. Enter the following menus: Powertrain / Engine and ECT / Utility / Pressure Discharge Valve Check.

      5. A01DYH9

        Press "Next".

      6. A01E0L4

        Press "Next" again to proceed.

      7. A01E32M

        Select the "Pressure Discharge Valve Check" type.

        Tech Tips


        • "Close to Open Check" opens the pressure discharge valve after the engine stops.

        • "Always Closed Check" holds the pressure discharge valve closed during the check.

      8. Press "Next".

      9. Perform troubleshooting based on the measurement results.

        Tech Tips


        • During "Close to Open Check", if there is no large change in fuel pressure when the pressure discharge valve is closed while the engine is running and after the engine is stopped, and if the value is 0 kPa when the pressure discharge valve is open, the system is normal.

        • Perform "Always Closed Check" if the value is not 0 kPa when the pressure discharge valve is open during "Close to Open Check". If the results are the same as during "Close to Open Check", there is a pressure discharge valve operation malfunction.

        • If the fuel temperature is high, perform "Pressure Discharge Valve Check" after the fuel has cooled to the outside air temperature.

        • If a large amount of fuel is leaking, the fuel pressure decreases when the engine is stopped. However, the condition of the pressure discharge valve can still be determined by comparing the measurement results of "Close to Open Check" and "Always Closed Check".
