ECD SYSTEM (w/o DPF) DATA LIST / ACTIVE TEST


  1. DATA LIST

    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.

    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 GTS to the DLC3.

    4. Turn the ignition switch to ON.

    5. Start the engine.

    6. Turn the GTS on.

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

    • Alternator malfunction

    • Electric load, lights, etc.

    Diagnostic Note:


    • This is outputs the alternator generation duty and is used to determine the electrical load.

    • 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.

    • 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:


    • "Accel Position" is the accelerator opening amount (%) for engine control use.

    • When the accelerator pedal position sensor output itself (Accel Sens. No.1 Volt %, Accel Sens. No.2 Volt %) is in the normal voltage range, another actuator malfunction has caused the fail-safe function to restrict the accelerator.

    • Without cruise, ECT or VSC requests, and without accelerator restriction by the fail-safe function, this is adjusted in proportion to the amount the accelerator pedal is depressed by the driver.

    • Accelerator pedal released: 0%

    • Accelerator pedal fully depressed: 100%

    Tech Tips

    Accel Sens. No.1 Volt % and Accel Sens. No.2 Volt % express the value obtained by dividing the output voltage from the accelerator pedal position sensor by 5. This is used only for diagnosing malfunctions in the accelerator pedal position sensor. Under normal conditions, it is sufficient to only check the final accelerator opening angle value "Accel Position".

    Calculated value
    • Suction control valve malfunction

    • Clogged fuel filter element subassembly

    Diagnostic Note:


    • When the (actual) fuel pressure is equal to the target fuel pressure, this value becomes 0.

    • This indicator can be used for diagnosing supply pump related malfunctions.

    • 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.

    Symptoms when out of range:

    Difficult to start, poor driveability, lack of power, abnormal combustion noise

    Diagnostic Note:


    • Common Rail Pressure is the actual common rail fuel pressure.

    • Inspect by comparing the fuel pressure with the target fuel pressure.

    • When in a stable condition such as when idling after warming up the engine, the fuel pressure is within +/- 5000 kPa of the target fuel pressure.

    • The ECM uses fuel pressure for feedback control of the target fuel pressure via the fuel supply pump assembly.

      The injection amount is determined based on the injection timing and fuel pressure. Also, the spray pattern is selected based on the fuel pressure.

    • For startup, at least 25000 kPa of fuel pressure is needed (take care as there is a response lag when the pressure rises).

    • When the fuel pressure is below 25000 kPa, it may cause rough idling.

    • When the fuel pressure has decreased by 20000 kPa from the target fuel pressure, there may be a lack of power.

    • If actual fuel pressure is 5000 kPa higher than the target fuel pressure, P1229 will be stored. When the actual fuel pressure is lower than the target fuel pressure, "P1608 Lack of Power" may be detected depending on the degree of deviation from the target pressure.

    • When the fuel pressure is higher than 220000 kPa, DTC P0088 will be stored.

    Diagnostic Note:


    • ECU-calculated value for the suction control valve actuation target current.

    • Value is large when a high fuel pressure is desired.

    • Normally, the value is between 800 and 2500 mA.

    • If the value is stuck at 3000 mA or higher, it indicates that the operation is poor (poor movement due to deposits, etc.).

    • When this deviates from the standard value, it indicates that for some reason, even though the pump is running hard, the actual fuel pressure is inconsistent with the target fuel pressure.

    • Injector clogging

    • Injector deterioration

    • Decrease in cylinder compression

    • Injector compensation code is incorrectly set (forgot to input code after replacement or made mistake during setting of code after replacing ECM with one from another 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:


    • 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.

    • "Injection Feedback Val" more than 3.0 mm3/st: Injector breakdown is causing injection volume deviation, or insufficient compression is causing poor combustion.

    • 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.

      Tech Tips


      • The ECM adjusts each cylinder so that the average "Injection Feedback Val" of the 4 cylinders is approximately 0 mm3/st.

      • If more than one cylinder has a positive correction value, a normal cylinder may have a value less than -3.0 mm3/st.

    Diagnostic Note:


    • When the fuel pressure becomes 15000 kPa or less, "Main Injection Period" is set to 0.

    • When the engine will not start, confirm that injection is performed.

    • When P0093, P0627 or P062D is stored, there is an engine stall request. At that time, "Main Injection Period" equals 0.

    Diagnostic Note:

    Before 5 seconds elapse after starting the engine, which is the DTC P1604 (Startability Malfunction) detection duration, this parameter indicates the distance driven during the previous trip. After 5 seconds elapse after starting the engine, this parameter indicates the distance driven during the current trip calculated from the vehicle speed signal.

    Tech Tips


    • Run Dist of Previous Trip in the freeze frame data present when the startability malfunction occurred (DTC P1604 detected) indicates the distance driven during the previous trip, but in all other cases, such as for the snapshot data of the Data List (real-time measurements), or for freeze frame data present when DTCs other than P1604 were detected, the value indicates the distance driven during the current trip.

    • If DTCs indicating insufficient power or problems with the diesel throttle or EGR valve are stored, confirm this item in the freeze frame data of the stored DTCs to determine the distance driven when the DTCs were stored. The distance driven can be used as a reference when troubleshooting.

  14. ACTIVE TEST

    Tech Tips

    Using the GTS to perform Active Tests allows relays, VSVs, actuators and other items to be operated without removing any parts. This non-intrusive functional inspection can be very useful because intermittent operation may be discovered before parts or wiring is disturbed. Performing Active Tests early in troubleshooting is one way to save diagnostic time. Data List information can be displayed while performing Active Tests.


    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.

    5. Perform the Active Test.

      • Ignition switch ON.

      • Engine is stopped.

      Test the Turbo Charger Step Motor Activate the turbocharger 40 to 100%

      Test is possible when the following conditions are met:


      • Ignition switch ON.

      • Engine is stopped.

      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.

      Activate the VN Turbo Open Activate the turbocharger ON/OFF Confirm that the engine is running.
      Activate the EGR Valve Close Activate the electric EGR control valve assembly ON/OFF Confirm that the vehicle is stopped and the engine is idling
      Control the Select Cylinder Fuel Cut Selected cylinder (cylinder #1 to #4) injector assembly fuel cut

      #1/#2/#3/#4

      ON/OFF

      Fuel injection is stopped while the test is ON.


      • Confirm that the vehicle is stopped and the engine is idling.

      • If the running condition of the engine does not worsen even though injection of the designated cylinder is stopped, the cylinder can be determined to be malfunctioning.

      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 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 GTS to the DLC3.

    4. Turn the ignition switch to ON and turn the GTS 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 "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 GTS.

      Tech Tips

      At first, the GTS 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 "Check the Cylinder Compression" Active Test 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.

  15. 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 GTS.

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


      1. Connect the GTS to the DLC3.

      2. Turn the ignition switch to ON.

      3. A01BHQS

        Turn the GTS on.

        Note

        Confirm the following conditions:


        • Engine is idling.

        • Vehicle is stopped.

        • Fuel pressure is not extremely high (below 100 MPa).

        • Fuel pressure is not extremely low (higher than 26 MPa).

        • Fuel pressure sensor is normal.

        • Battery voltage is higher than 8 V.

        Tech Tips

        When the common rail pressure is unstable, the fuel pressure may decrease to a level where the test cannot be performed. In this situation, wait until the common rail pressure meets the test condition, and then perform the test.

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

      5. A01BC3E

        Press "Next".

      6. A01BDO9

        Press "Next" again to proceed.

      7. A01BFFZ

        1. Press "Next" again to proceed.

        2. Press "Start" again to proceed.

          A01BAN2E01

          *1: When "Start" is pressed, the pressure discharge valve check begins.

          *2: If "Save" is pressed after the pressure discharge valve check, the data recorded during the valve check can be saved.

      8. A01BFFZ

        Select the check type "Close to Open Check" or "Always Closed Check".

        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.


        1. Press "Next".

        2. Perform troubleshooting based on the measurement results.

          A01BF8J

          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".
