Ecd System -- Data List / Active Test



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.
  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 intelligent tester on.

Diagnostic Note:
  1. This is outputs the alternator generation duty and is used to determine the electrical load.
  2. Can be used to determine whether a higher-than-normal injection volume at idle, etc. is due to 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 the maximum value, there is an electrical system abnormality, like battery deterioration.

Diagnostic Note:
  1. Fuel press is the actual common rail fuel pressure.
  2. Inspect by comparing the fuel pressure with the target fuel pressure.
  3. When in a stable condition such as when idling, the fuel pressure is within +/-5000 kPa of the target fuel pressure.
  4. The ECM uses fuel pressure for feedback control of the target fuel pressure via the supply pump.
    The injection amount is determined based on the injection timing and fuel pressure.
    Also, the spray pattern is selected based on the fuel pressure.
  5. For startup, at least 25000 kPa of fuel pressure is needed (take care as there is a response lag when the pressure rises).
  6. When the fuel pressure is below 25000 kPa, it may cause rough idling.
  7. When the fuel pressure has decreased by 20000 kPa from the target fuel pressure, there may be a lack of power.
  8. If the actual fuel pressure is 40000 kPa higher than the target fuel pressure, P1229 will be stored. When it is lower than the target fuel pressure, a lack of power will occur, but a DTC will not be stored.

Inj Vol Feedback Learning
Injection volume feedback learning value:
Min.: -10 mm3/st, Max.: 9.92 mm3/st
Idling: -4.0 to 4.0 mm3/st
Learned value
  1. Injector assembly
  2. Fuel filter element sub-assembly
  3. Inferior quality fuel
Symptoms when out of range:
-
Diagnostic Note:
  1. "Inj Vol Feedback Learning" is calculated by the deviation of injection volume at idle speed when the engine is warmed up.
  2. When the engine is warmed up and in a stable idling condition, this learning will be performed.
  3. When poor quality fuel or sustained low-speed driving causes a reduction in injector nozzle hole area (reducing injection volume), the "Inj Vol Feedback Learning" will become an abnormal value (for example, 2.0 mm3/st). At that time, if all of "Injection Feedback Value #1 to #4" are within specifications (for example, less than 2 mm3/st), all cylinders are considered to be malfunctioning. If "Injection Feedback Value #1 to #4" is large at only one cylinder (for example, more than 3 mm3/st), that cylinder may have a malfunction.
  4. Other than the injector assemblies, fuel filter element sub-assembly pore blockage, poor-quality fuel, compression loss and large engine friction can all cause "Inj Vol Feedback Learning" to be abnormal.
  5. When the engine is started cold, the idling speed is high and gradually slows down in accordance with the increase in engine coolant temperature. If the changing value of the idling speed is unstable while the engine is warming up, check "Inj. FB Vol. For Idle".
  6. When combustion noise or driveability is bad, check "Inj Vol Feedback Learning" as part of the injection system deterioration diagnosis.
  7. Only when the ignition switch is turned off is the learned value updated gradually.

  5. Driving with the accelerator fully open at 2000 rpm: 11.2 mm3/st
  6. Driving with the accelerator fully open at 3000 rpm: -19.5 mm3/st
Symptoms when out of range:
-
Diagnostic Note:
  1. When the (actual) fuel pressure is equal to the target fuel pressure, this value becomes 0.
  2. This indicator can be used for diagnosing supply pump related malfunctions.
  3. When this value (absolute value) is large, it indicates that the difference between the actual and target fuel pressure is also large.
    A positive value indicates that the pressure feed is being increased due to insufficient pressure. A negative value indicates that pressure is being reduced due to excessive rail pressure.
    When the suction control valve does not close properly, it causes rail overpressure, and this value and the "Pump SCV Learning Value" slip to the negative volume side.

Results of real-vehicle check:
Idling (warm up the engine): 0 mm3/st (2 minutes after starting the vehicle)
Symptoms when out of range:
Rough idling, black smoke, white smoke, poor driveability, lack of power, abnormal combustion noise, difficult to start
Diagnostic Note:
  1. When idling after warmup, the injection amount for each cylinder is corrected to optimize the difference between the engine speed of each cylinder.
    Example: For cylinders that are slowing the engine speed compared to other cylinders, the injection volume is increased.
  2. "Injection Feedback Val" more than 3.0 mm3/st: Injector breakdown is causing injection volume deviation, or insufficient compression is causing poor combustion.
  3. Even if "Injection Feedback Val" for a cylinder is less than -3.0 mm3/st, the cylinder with this value does not necessarily have a problem.
    HINT:
    1. The ECM adjusts each cylinder so that the average "Injection Feedback Val" of the 4 cylinders is approximately 0 mm3/st.
    2. If more than one cylinder has a positive correction value, a normal cylinder may have a value less than -3.0 mm3/st.

HINT:
*: 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 more than the other cylinders, it can be determined that the compression pressure of that cylinder is 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.
    HINT:
    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.
    HINT:
    After performing the above procedure, the "Check the Cylinder Compression" Active Test will start. Fuel injection for all cylinders is prohibited and the engine speed measurement of each cylinder enters 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.
    HINT:
    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.
    NOTICE:
    1. After the "Check the Cylinder Compression" Active Test is turned on, it will automatically turn off after 255 seconds.
    2. When the "Check the Cylinder Compression" test is off and the engine is cranked, the engine will start.
    3. 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.
    4. Use a fully-charged battery.

SYSTEM CHECK


  1. Activate the Pressure Discharge Valve Check

    HINT:
    1. This is the procedure for troubleshooting fuel pressure control malfunctions and combustion problems.
    2. Malfunctions can be determined by checking the fuel pressure when performing a fuel cut and operating the pressure discharge valve with the intelligent tester.
    3. 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.

      NOTICE:
      Confirm the following conditions:
      1. Engine is idling.
      2. Vehicle is stopped.
      3. Fuel pressure is not extremely high (below 100000 kPa).
      4. Fuel pressure sensor is normal.
      5. Battery voltage is higher than 8 V.
    5. Enter the following menus: Powertrain / Engine and ECT / Utility / Pressure Discharge Valve Check.

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

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



    13. Perform troubleshooting based on the measurement results.

      HINT:
      1. 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.
      2. 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.
      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 discharge valve can still be determined by comparing the measurement results of "Close to Open Check" and "Always Closed Check".
