DATA LIST

HINT:
Using the intelligent tester 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.

NOTICE:
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.

HINT:
  1. When reading the values of Data List, confirm that PM regeneration is not activating (value of "After Injection Period" is 0) by entering the following menus: Powertrain / Engine and ECT / Data List / After Injection Period.
    If PM regeneration is activating (value of "After Injection Period" is not 0), drive the vehicle until the PM regeneration is complete (value of "After Injection Period" becomes 0).
  2. When idling, EGR cut occurs under either of the following conditions:
    1. PM regeneration is activating.
    2. Idling time is long (approximately 20 minutes or more).
      If EGR is cut off when idling and PM regeneration is not activating, when the vehicle is driven in 5th gear at 70 km/h for 10 minutes, EGR resumes.

  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.

  5. Start the engine.

  6. Turn the tester on.

  2. Can be used to determine whether a higher than normal injection volume at idle, etc. is resulting from electrical loading or from some other source. For example, when the duty is not high but the idling injection volume is high, there is injector volume degradation or high engine friction.
  3. Can be used for judging whether or not a malfunctioning component in the electrical system is generating continual generation requests (e.g., battery deterioration is causing an unending full recharge request, etc.). Regardless of whether or not an auxiliary device like the A/C or heater is active, if the alternator duty is always at MAX status, there is an electrical system abnormality, like battery deterioration.

HINT:
*: The speed of each cylinder can be measured (compression test) by using the intelligent tester.
In the compression test, perform Active Test using intelligent tester (Check the Cylinder Compression) and crank the engine 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 / All Data / 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. Push the snapshot button to turn the snapshot function on.

    HINT:
    Using the snapshot function, data can be recorded during the Active Test.

  7. While the engine is not running, press the RIGHT or LEFT button to Change the Cylinder Compression to ON.

    HINT:
    After performing the above procedure, Check the Cylinder Compression will start. Fuel injection for all cylinders is prohibited and each cylinder engine speed measurement enters standby mode.

  8. Crank the engine for about 10 seconds.
  9. Monitor the engine speed (Engine Speed of Cyl #1 to #4, Av Engine Speed of All Cyl) displayed on the tester.

    HINT:
    After approximately 10 seconds of engine cranking, the engine speed measurement of each cylinder will change to the actual engine speed.

    NOTICE:
    1. Do not crank the engine continuously for 20 seconds or more.
    2. If Check the Cylinder Compression needs to be performed after it is turned ON and performed once, press Exit to return to the Active Test menu screen. Then perform Check the Cylinder Compression again.
    3. Use a fully-charged battery.

  10. Stop cranking the engine, and then change "Check the Cylinder Compression" to OFF after the engine stops.

    NOTICE:
    If the Active Test is changed to OFF while the engine is being cranked, the engine will start.

  11. Push the snapshot button to turn the snapshot function off.
  12. Select the recorded data and display the data as a graph.
  13. Check the change in engine speed values.
For reference, the results of a "real-vehicle check" are as shown below:

      1. Engine is idling.
      2. Vehicle is stopped.
      3. Fuel pressure is not extremely high (less than 100000 kPa).
      4. Fuel pressure sensor is normal.
      5. Battery voltage is more than 8 V.

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



      5. A237501

    5. Press "Next".



      6. A237502

    6. Press "Next" again to proceed.



      7. A237503

    7. Select the "Pressure Discharge Valve Check" type.

      HINT:
      1. "Close to Open Check" opens the pressure control valve after the engine stops.
      2. "Always Closed Check" holds the pressure control valve closed during the check.

    8. Press "Next".



    9. Perform troubleshooting based on the measurement results.


      A237504

      HINT:
      1. During "Close to Open Check", if there is no large change in fuel pressure when the pressure control valve is closed while the engine is running and after the engine is stopped, and if the value is approximately 0 kPa when the pressure control valve is open, the system is normal.
      2. Perform "Always Closed Check" if the value is not 0 kPa when the pressure control valve is open during "Close to Open Check". If the results are the same as during "Close to Open Check", there is a pressure control valve operation malfunction.
      3. If the fuel temperature is high, perform "Pressure Discharge Valve Check" after the fuel has cooled to the outside air temperature.
      4. If a large amount of fuel is leaking, the fuel pressure decreases when the engine is stopped. However, the condition of the pressure control valve can still be determined by comparing the measurement results of "Close to Open Check" and "Always Closed Check".
