ECD SYSTEM DATA LIST / ACTIVE TEST


  1. DATA LIST

    Tech Tips

    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.

    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.

    Tech Tips


    • When read 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 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.

    Calculate Load

    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 3000 rpm: 80.3 to 99.6%

    • Driving with the accelerator fully open at 4000 rpm: 96.4 to 98%

    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%

    • Idling (warm up the engine): 15.0% (2 minutes after starting the engine)

    • Running without load (2500 rpm): 16%

    • Running without load (4500 rpm): 30.1%

    • Driving with the accelerator fully open at 2000 rpm: 86.6%

    • Driving with the accelerator fully open at 3000 rpm: 99.6%

    • Driving with the accelerator fully open at 4500 rpm: 100%

    Diagnostic Note:

    Calculate load = (Actual inner torque / Full inner torque) x 100.

    • Cranking (295 rpm): 2.72 g/sec.

    • Idling (warm up the engine): 5.0 g/sec. (2 minutes after starting the vehicle and "Actual EGR Valve Pos." = 56%)

    • Idling (warm up the engine): 8.5 g/sec. (2 minutes after starting the vehicle and "Actual EGR Valve Pos." = 0.3%)

    • Running without load (2500 rpm): 21.2 g/sec. (at "Actual EGR Valve Pos." = 56%)

    • Driving with the accelerator fully open at 3000 rpm: 72.47 g/sec.

    • Driving with the accelerator fully open at 4500 rpm: 87.8 g/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.

    • If the value is always approximately 0 g/sec.:


      • Mass air flow meter power source circuit is open.

      • VG circuit is open or shorted.

    • If the value is always 200 g/sec. or more:


      • EVG circuit is open.

    Tech Tips

    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 5th gear at 70 km/h for 10 minutes, EGR resumes.

    Diagnostic Note:


    • 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.

    • Driving with the accelerator fully open at 4500 rpm: 99.6%

    Symptoms when out of range:

    -

    Diagnostic Note:


    • "Accel Position" is the accelerator opening angle (%) 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 to restrict the accelerator.

    • Without VSC requests, and without accelerator restriction by the fail-safe, this is adjusted proportionally to the depressing of the accelerator pedal by the driver.

    • Accelerator fully closed: 0%

    • Accelerator fully open: 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 accelerator opening angle final value "Accel Position".

    Diagnostic Note:

    Tech Tips

    *: At the beginning of engine cranking, the speed of each cylinder is measured (compression test).

    In the compression test, need to disconnect the injector connectors of all cylinders, 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 and disconnect the injector connectors of all cylinders.

    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 / Data List / 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. Crank the engine for about 10 seconds.

      Note


      • Do not crank the engine for more than 20 seconds.

      • Use a fully-charged battery.

    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 +/-10 MPa 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.

    Diagnostic Note:


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


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

    • Value becomes stuck at 3 A 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.

  11. ACTIVE TEST

    Tech Tips

    Using the intelligent tester 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.
