ECD SYSTEM(w/ 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.

    Engine Speed Engine speed Min.: 0 rpm, Max.: 6000 rpm
    • 50 to 400 rpm: Cranking

    • 800 to 900 rpm: Idling with warm engine

    When the crankshaft position sensor is malfunctioning, "Engine Speed" is approximately 0 or varies greatly from the actual engine speed.
    Calculate Load Load calculated by ECM Min.: 0%, Max.: 100%
    • Idling: 6.6 to 14.2%

    • Running without load (3000 rpm): 15.5 to 24.0%

    Calculated load = (Final injection volume / max. injection volume at current engine speed) x 100.
    MAF Air flow rate from mass air flow meter sub-assembly Min.: 0 gm/sec, Max.: 400 gm/sec
    • Idling: 3 to 18 gm/sec

    • Running without load (3000 rpm): 45 to 94 gm/sec

    Tech Tips

    Depends on EGR rate

    Based on the MAF, the ECM controls the fuel injection volume, injection timing, EGR, etc.
    Atmosphere Pressure Atmospheric pressure value Min.: 0 kPa(abs), Max.: 255 kPa(abs) Actual atmospheric pressure
    • With the ignition switch ON, when the difference between the atmospheric pressure sensor and intake manifold absolute pressure is 10 kPa or more, there is a malfunction in one of the sensors.

    • With the ignition switch ON, when the atmospheric pressure is 0 kPa or 140 kPa, there is a malfunction in the sensor circuit.

    • Standard atmospheric pressure: 101 kPa.

    • For every 100 m increase in elevation, pressure drops by 1 kPa.

      This varies by weather (high atmospheric pressure, low atmospheric pressure).

    MAP Absolute pressure inside intake manifold Min.: 0 kPa, Max.: 320 kPa
    • Idling: 90 to 100 kPa (depends on barometric pressure and amount of EGR)

    • Engine running at 3000 rpm: 110 to 135 kPa


    • When the ignition switch is ON or the vehicle is idling, the intake manifold absolute pressure and atmospheric pressure are approximately the same (standard atmospheric pressure = 101 kPa).

      Above approximately 1500 rpm, the turbo becomes effective and the pressure becomes higher than atmospheric pressure.

    • Inspect while comparing with "Target Booster Pressure".

    • With the accelerator fully open, if the actual manifold absolute pressure (MAP) is low compared to the target booster pressure by at least 20 kPa for 5 seconds or more, a feeling of insufficient power will occur.

    Coolant Temp Engine coolant temperature Min.: -40°C, Max.: 140°C After warming up engine: 70 to 90°C (158 to 194°F)
    • If the value is -40°C (-40°F) or 140°C (284°F), the sensor circuit is open or shorted.

    • After a long soak, the coolant temperature, intake air temperature and ambient temperature are approximately equal.

    Intake Air Intake air temperature Min.: -40°C, Max.: 140°C Equivalent to temperature at location of mass air flow meter sub-assembly
    • After a long soak, the engine coolant temperature, intake air temperature and ambient temperature are approximately equal.

    • If the value is -40°C (-40°F) or 140°C (284°F), the sensor circuit is open or shorted.

    Intake Air Temp (Turbo) Supported Intake air temp (Turbo) support Unsupp or Supp -
    • Supp: The item is supported by the vehicle.

    • Unsupp: The monitor is not supported by the vehicle.

    Intake Air Temp (Turbo) Intake air temperature after intercooler Min.: -40°C, Max.: 190°C 70°C (158°F) or less
    • This is the intake air temperature at the intake manifold (after the intercooler).

    • During fail-safe operation, the value is set to 165°C (329°F). As the value is set to a high temperature, the turbo pressure may be suppressed and there may be a lack of power.

    Engine Run Time Engine run time Min.: 0 sec., Max.: 65535 sec. Time after the ignition switch turned to ON Time passed since the ignition switch was turned to ON.
    Initial Engine Coolant Temp Initial engine coolant temperature Min.: -40°C, Max.: 120°C Engine coolant temperature when engine started For freeze frame data, this tells whether the malfunction happened at a cold start or with a warm engine.
    Initial Intake Air Temp Initial intake air temperature Min.: -40°C, Max.: 120°C Intake air temperature when engine started -
    Battery Voltage Battery voltage Min.: 0 V, Max.: 15 V 11 to 14 V
    • If 11 V or less, characteristics of some electrical components change.

    • Symptoms when out of range:


      • If 5 V or less, starting becomes difficult

    Alternate Duty Ratio Alternator generation duty ratio Min.: 0%, Max.: 100%
    • No electrical load at idling:

      20 to 60%

    • High electrical load at idling:

      100%


    • 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 such as the A/C or heater is active, if the alternator duty is always at the maximum value, there is an electrical system abnormality, such as battery deterioration.

    Glow Relay Request Status of the glow relay request ON or OFF - -
    Glow Control Unit Duty Glow plug controller duty Min.: 0%, Max.: 127.5% - This is the ECM command.

    • Accelerator pedal released:

      0%

    • Accelerator pedal fully depressed:

      100%


    • "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 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%

    Accel Sens. No.1 Volt % Accelerator position No. 1 Min.: 0%, Max.: 100%
    • Accelerator pedal released:

      10 to 22%

    • Accelerator pedal fully depressed:

      52 to 90%

    Read value with ignition switch ON (do not start engine).

    Tech Tips

    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".

    Accel Sens. No.2 Volt % Accelerator position No. 2 Min.: 0%, Max.: 100%
    • Accelerator pedal released:

      24 to 40%

    • Accelerator pedal fully depressed:

    • Unsupp: The monitor is not supported by the vehicle.

    Actual Throttle Position Actual throttle position Min.: -20%, Max.: 120% Idling after engine warmed-up: 0 to 92%

    Closing percentage of the throttle valve.


    • Fully closed: 0%.

    • Fully open: 100%.

      Tech Tips

      There is no connection with the accelerator. However, under full load, the throttle is usually fully open (100%).

    Symptoms when out of range:


    • Stuck closed: Engine stall, difficult to start, lack of power, black smoke, rough idle

    • Stuck open: Loud turbocharging sound, bad vibration when engine is stopped

    • When ECM detects a malfunction of the diesel throttle (MIL on), engine power is restricted so that the vehicle can drive with a maximum speed of 80 to 100 km/h.

    Actual Throttle Position #2 Supported Actual No. 2 throttle position support Unsupp or Supp -
    • Supp: The item is supported by the vehicle.

    • Unsupp: The monitor is not supported by the vehicle.

    Actual Throttle Position #2 Actual No. 2 throttle position Min.: -20%, Max.: 120% - -
    Throttle Motor DUTY Throttle motor duty Min.: 0%, Max.: 100% - When the moving force to open and close the diesel throttle valve increases, the value of the Throttle Motor Duty increases.
    Throttle Close Learning Val. Throttle fully closed position learned value Min.: 0 deg, Max.: 84 deg 14 to 22 deg
    • When the ignition switch is turned from ON to off and 5 seconds elapse, learning of "Throttle Close Learning Val." will be complete.

    • When "Throttle Close Learning Val." is outside of the normal range, a foreign object may lodged in the throttle valve.

    • If the value is stuck at the upper limit of 21.25 deg, there is a chance that a malfunction is present.

      However, as the initial value for the learned value is 21.25 deg, it is necessary to check the value after learning is completed.

    Throttle Sensor Volt % Absolute throttle position sensor Min.: 0%, Max.: 100%
    • Ignition switch ON: 60 to 100%

    • Warmed-up and idling: 8 to 100%


    • Throttle position sensor output voltage is converted using 5 V = 100%.

    • When fully closed: 20%.

    • When fully open: 82%.

    • When the ignition switch is turned from off to ON, the throttle valve fully opens once.

    • When the ignition switch is turned from ON to off, the throttle valve fully closes once.

    Symptoms when out of range:


    • Stuck closed: Engine stall, difficult to start, rough idling, lack of power, black smoke, white smoke

    • Stuck open: Loud turbocharging sound, bad vibration when engine is stopped

    • When the ECM detects a malfunction with the diesel throttle (MIL on), engine power is restricted but city driving is possible.

    Throttle Motor DUTY Throttle motor duty Min.: 0%, Max.: 100% Warmed-up and idling: 0 to 80%
    • When drive requests to open and close the diesel throttle valve increase, the throttle motor duty value increases.

    • Since the throttle valve opening and closing directions cannot be determined when the throttle motor duty value is high during drive control, the opening and closing directions are determined from the throttle target opening angle and throttle actual opening angle.

    • If the throttle motor duty value continues to be high, there may be an operation malfunction due to deposits in the throttle.

  4. Diesel Injection System


    Powertrain > Engine > Data List
    Tester Display Measurement Item Range Normal Condition Diagnostic Note
    Injection Volume Injection volume

    Min.: 0 mm3/st, Max.: 1279.98 mm3/st

    Idling: 3 to 15 mm3/st


    • Injection amount for each combustion.

    • If injector assemblies are clogged fuel quality is poor, the fuel filter element sub-assembly is clogged, or engine friction increases, "Injection Volume" will increase.

    • If there is a malfunction due to low turbocharger pressure or a low intake air volume, the injection volume is limited and there is a lack of power.

    Inj. FB Vol. for Idle Idle stability status integral control volume

    Min.: -80 mm3/st, Max.: 79 mm3/st

    -20 to 30 mm3/st


    • When the actual engine speed does not match the target idling speed, this corrects the injection volume.

      If this item displays 10 mm3/st or more or -10 mm3/st or less even with the engine completely warmed up and the air conditioning and other electrical loads off, the internal parts of the engine may be damaged, or the fuel injection system or other auxiliary components may be malfunctioning.

    • Only calculated and reflected at idle.

    - -
    Injection Feedback Val #1 Injection volume correction for No. 1 injector assembly

    Min.: -10 mm3/st, Max.: 10 mm3/st

    Idling: -3.0 to 3.0 mm3/st


    • 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.

    Injection Feedback Val #2 Injection volume correction for No. 2 injector assembly

    Min.: -10 mm3/st, Max.: 10 mm3/st

    Idling: -3.0 to 3.0 mm3/st

    Main Injection Period Main injection period Min.: 0 μs, Max.: 65535 μs Idling: 100 to 600 μs
    • 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.

      Tech Tips

      As the engine stalls 1 minute after the MIL illuminates, freeze frame data cannot be checked.

    After Injection Period After injection period Min.: 0 μs, Max.: 65535 μs -

    Check to see if "After Injection Period" is not zero when the following symptoms occur:

    Black smoke, poor driveability.

    -100 to 100 mm3/st at standard temperature


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

    • This indicator can be used for diagnosing fuel supply pump assembly 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 pre-stroke control valve is malfunctioning, it causes rail overpressure, and this value slips to the negative volume side.

    • Injection Pressure Correction displays the value calculated by the ECM.

    PCV Energization Timing Pre-stroke control valve energization timing Min.: 0 deg(CA), Max.: 639.9 deg(CA) Idling: 0 to 180 deg(CA)
    • Displays the pre-stroke control valve energization timing.

    • When Common Rail Pressure is higher than Target Common Rail Pressure and the fuel supply pump assembly is not commanded to discharge, the value of PCV Energization Timing is -1.

    • When the fuel supply pump assembly is commanded to discharge, PCV Energization Timing changes to a value between 70 and 180. The larger the value, the smaller the amount of discharge.

    • PCV Energization Timing displays the value calculated by the ECM.

    Target Common Rail Pressure Target common rail pressure Min.: 0 kPa(abs), Max.: 250000 kPa(abs) 20000 to 220000 kPa when engine running
    • Inspect the (actual) fuel pressure, comparing it with the common rail target value.

    • Considered normal when the actual fuel pressure is within 5000 kPa of the target fuel pressure under stable conditions when idling after warm up the engine.

    Common Rail Pressure Supported Common rail pressure support Unsupp or Supp -
    • Supp: The item is supported by the vehicle.

    • Unsupp: The monitor is not supported by the vehicle.

    Common Rail Pressure Actual common rail pressure Min.: 0 kPa(abs), Max.: 250000 kPa(abs) Idling: 30000 to 50000 kPa
    • 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 warm 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 240000 kPa, DTC P0088 will be stored.

    Injection Volume (Cylinder1) Injection volume (cylinder 1) Min.: 0 ml, Max.: 2.047 ml - This is the injection volume for 10 injections.

    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 DPF system, 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.

    Glow Request Lighting Time Glow Request Lighting Time Min.: 0 ms, Max.: 33423 ms -
    • By comparing Glow Request Lighting Time to IG-ON Time, the operation state (whether the engine was started, etc.) can be determined.

    Engine Coolant Temp High Status of the engine coolant temp High ON or OFF OFF
    • When DTC P1608 is output, this item indicates whether the cause of lack of power is due to a high engine coolant temperature.

    • This item indicates whether the fuel injection volume was reduced for a certain period of time due to a high engine coolant temperature (overheating). If this is the case, this item displays "ON" and DTC P1608 (lack of engine power) is stored.

    MAF/Estimate MAF Ratio Ratio of intake air amount to estimated intake air amount Min.: 0, Max.: 2.55

    Engine speed 4000 rpm, EGR system off:

    0.6 to 1.4


    • Even when the system is normal, the value may deviate from the range specified in Normal Condition for a short period of time (approximately 1 second).

    • 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.

  20. 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.

      • Engine is stopped.

      Control the Select Cylinder Fuel Cut Selected cylinder (cylinder #1 to #4) injector fuel cut 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. Push the snapshot button to turn the snapshot function on.

      Tech Tips

      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 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.

    8. Crank the engine for about 10 seconds.

      Tech Tips

      Continue to crank the engine until the values change from the default value (51199 rpm).

    9. 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.

    10. 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.

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

    12. Select "Stored Data" on the GTS screen, select the recorded data and display the data as a graph.

      Tech Tips

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

    13. Check the change in engine speed values.

      Tech Tips

      As the data values of the Active Test return to their default values when cranking is stopped, the engine speed value of each cylinder cannot be observed. Therefore, it is necessary to use the data recorded with the snapshot function to check the engine speed values recorded during cranking.

  21. 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. B0024MP

        Turn the GTS on.

        Note

        Confirm the following conditions:


        • Engine is idling.

        • Vehicle is stopped.

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

        • Fuel pressure is not extremely low (higher than 26000 kPa).

        • 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.


        Powertrain > Engine and ECT > Utility
        Tester Display
        Pressure Discharge Valve Check

      6. B0026LN

        Press "Next" again to proceed.

      7. B0025J9

        Select the check type "Valve Check for Graph".


        1. Press "Next" again to proceed.

        2. Press "Start" again to proceed.

          B002618E03

          Tech Tips

          *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. 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. B0025J9

          Press "Next".

      9. Perform troubleshooting based on the measurement results.

        B0025K4

        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".
