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. Outputs the alternator generation duty in order to see the electrical load.
  2. 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.
  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 MAX status, there is an electrical system abnormality, like battery deterioration.

Diagnostic Note:
  1. Fuel pressure 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 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, "Lack of Power" will occur, but a DTC will not be stored.

    8. Press "Next".



    9. Perform troubleshooting based on the measurement results.


      A204070


      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".
