  1. DATA LIST

    Tip:

    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.

    Tip:
    • 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).

    • When idling, EGR cut occurs under either of the following conditions:


      • PM regeneration is activating.

      • 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 4th gear between 90 and 100 km/h (56 and 62 mph) for 30 minutes, EGR resumes.


    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.

      Tip:
      • To display the list box, press the pull down menu button next to Primary. Then select a measurement group.

      • When you select a measurement group, the ECM data belonging to that group is displayed.

    Calculated load by ECM/

    Min.: 0%, Max.: 100%


    • Idling: 10 to 35%

    • Running without load (2500 rpm): 10 to 35%

    • Driving with the accelerator fully open at 80 to 100%

    Calculated value by ECM Malfunction in which turbo pressure or Mass Air Flow (MAF) decreases

    Results of real-vehicle check:


    • Ignition switch ON: 0.0%

    • Cranking (243 rpm): 49.4%

    • Idling (warm up the engine): 18.0% (2 minutes after starting the engine)

    • Running without load (2500 rpm): 20.7%

    • Running without load (4000 rpm): 24.3%

    Diagnostic Note:

    Results of real-vehicle check:


    • Ignition switch ON: 0 gm/sec.

    • Cranking (243 rpm): 3.86 gm/sec.

    • Idling (engine warmed up): 8.88 gm/sec.

    • Running without load (2500 rpm): 34.86 gm/sec.

    • Running without load (4000 rpm): 55.55 gm/sec.

    Symptoms when out of range:

    Rough idling

    Diagnostic Note:


    • Based on the MAF, the ECM controls the fuel injection volume, injection timing, EGR, etc.

    • If the MAF value exceeds the normal condition when the engine is idling, the EGR passage is possibly clogged.

    Tip:

    If the time of engine idling is long (approximately 20 minutes or more), EGR will be cut off. At this time, if the vehicle is driven in 4th gear between 90 and 100 km/h (56 and 62 mph) for 30 minutes, EGR resumes.

    Diagnostic Note:


    • Outputs the alternator generation duty in order to see the electrical load.

    • 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.

    • 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.

    "Engine speed" of all cylinders almost same - Cyl #1 compression goes down

    Symptoms when out of range:

    When the engine speed of all cylinders is not equal, idling will be rough.

    Diagnostic Note:


    • This is output only when Check the Cylinder Compression is performed using the Active Test.

    • The engine is cranked for approximately 10 seconds, then the speed of each cylinder is measured (compression test).

    • Indicates the speed of each cylinder when cranking. Example - Normal: Engine speed of all cylinders is approximately equal. When No. 1 cylinder compression is extremely low, "Engine speed of Cyl #1" is approximately 300 rpm, and "Engine speed of Cyl #2 to #4" is approximately 200 rpm.

    • Usually the GTS displays the value of when the engine is started.

    - - -
    Tip:

    *1: The speed of each cylinder can be measured (compression test) by using the GTS.

    In the compression test, perform Active Test using GTS (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 GTS to the DLC3.

    4. Turn the ignition switch to ON.

    5. Turn the GTS on.

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

    7. Push the snapshot button to turn the snapshot function on.

      Tip:

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

    8. While the engine is not running, press the ON button to Change the Cylinder Compression to ON.

      Tip:

      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.

    9. Crank the engine for about 10 seconds.

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

      Tip:

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

      Note:
      • Do not crank the engine continuously for 20 seconds or more.

      • 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.

      • Use a fully-charged battery.

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

      Note:

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

    12. Push the snapshot button to turn the snapshot function off.

    13. Select the recorded data and display the data as a graph.

    14. Check the change in engine speed values.

    Diagnostic Note:


    • Fuel 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, the fuel pressure is within +/-10000 kPa of the target fuel pressure.

    • 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.

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

    • Value becomes stuck at 1800 mA or more or 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.

    Diagnostic Note:


    • When idling after warm up, 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 2.0 mm3/st: Injector assembly breakdown is causing injection volume deviation, or insufficient compression is causing poor combustion.

    Diagnostic Note:


    • This value is the EGR position sensor output voltage.

    • When the value is at the upper or lower limit of the normal range, it is possible that a foreign object is lodged in the EGR valve seat area.

    • As the lower and upper limits are 0.7 V and 1.7 V respectively, if the value becomes stuck at either of these values, there is a malfunction in the lift sensor or the valve position may be misaligned (foreign matter is present, etc.).

    Symptoms when out of range:

    Lack of power

    Diagnostic Note:


    • This item indicates the ratio of the intake air amount to the estimated intake air amount. The estimated air amount is calculated using the intake manifold pressure and intake air temperature.

    • When DTC P1608 is stored, this item is useful in determining whether there is a problem in the turbocharger system or a disconnected or leaking pipe in the high pressure intake system when the boost pressure is insufficient.

    • When performing troubleshooting, this information is only valid when there is a high load (the diesel throttle is fully open) and the EGR system is off.

  16. ACTIVE TEST

    Note:

    Do not perform the Active Test while stop and start control is being performed. (w/ stop and start system)

    Tip:

    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.

      • 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 confirmed to be malfunctioning.

      • DTCs may be output after this Active Test. Make sure to check for DTCs after this Active Test. If any DTCs are output, make sure to clear them.

      Check the Cylinder Compression*1 Check the cylinder compression pressure ON/OFF Fuel injection stops in all cylinders
      Tip:

      *1 Check the Cylinder Compression

      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 GTS to the DLC3.

      4. Turn the ignition switch to ON.

      5. Turn the GTS on.

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

      7. Push the snapshot button to turn the snapshot function on.

        Tip:

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

      8. While the engine is not running, press the ON button to change Check the Cylinder Compression to on.

        Tip:

        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 enters standby mode.

      9. Crank the engine for about 10 seconds.

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

        Tip:

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

        Note:
        • Do not crank the engine continuously for 20 seconds or more.

        • If it is necessary to crank the engine again after Check the Cylinder Compression has been changed to ON and the engine has been cranked once, press Exit to return to the Active Test menu screen. Then change Check the Cylinder Compression to ON and crank the engine.

        • Use a fully-charged battery.

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

        Note:

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

      12. Push the snapshot button to turn the snapshot function off.

      13. Select the recorded data and display the data as a graph.

        Tip:

        If the data is not displayed as a graph, the change of the values cannot be observed.

      14. Check the change in engine speed values.

  17. SYSTEM CHECK


    1. Activate the Pressure Discharge Valve Check

      Tip:
      • This procedure is 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. A01VJN4

        Turn the GTS 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 higher than 8 V.

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

      5. A01VI6J

        Press "Next".

      6. A01VIK5

        Press "Next" again to proceed.

      7. A01VGAC

        Select the check type "Valve Check for Graph".


        1. Press "Next" again to proceed.

        2. A01VFDIE04

          Press "Start" again to proceed.

        *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. A01VGAC

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

        Tip:
        • "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. A01VK2A

          Perform troubleshooting based on the measurement results.

          A01VKQ6E01
          Tip:
          • 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, wait until the fuel temperature becomes the same as the ambient temperature before performing "Pressure Discharge Valve Check".

          • 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".

    2. Engine Oil Pressure Control Check

      Tip:
      • Check whether the oil pressure control system is operating properly when the oil pressure switching valve is forcibly operated.

      • Perform this check when DTC P0524 is output.


      1. Connect the GTS to the DLC3.

      2. Turn the ignition switch to ON.

      3. Turn the GTS on.

      4. Start the engine and warm it up.

        Tip:

        Confirm that the engine coolant temperature is between 70 and 90°C (158 and 194°F) after the engine is warmed up, as the oil pressure changes according to the engine coolant temperature.

      5. Enter the following menus: Powertrain / Engine and ECT / Utility / Engine Oil Pressure Control Check.

        Note:

        Confirm the following conditions:


        • Engine is idling.

        • Vehicle is stopped.

        • Shift lever is in neutral.

        • Engine coolant temperature is in specified range.

      6. Press "Next".

        Tip:
        • Even when the engine is warmed up, there are some instances where the oil pressure control system check cannot be performed.

        • The engine speed will increase during the oil pressure control system check.

      7. A01VLI5E01

        Perform troubleshooting based on the measurement results.

        Tip:
        • The average oil pressure over 1 second when the valve is operated is displayed.

        • The engine oil pressure measured every 0.1 seconds is displayed on the detailed information screen.
