CONTINUOUSLY VARIABLE TRANSAXLE SYSTEM 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. Turn the GTS on.

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

      Tech Tips


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

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

      • Measurement Group List / Description


        • All Data / All data

      Vehicle speed/

      Min.: 0 km/h (0 mph)

      Max.: 255 km/h (158 mph)

      Actual vehicle speed
      • This is the current vehicle speed.

      • The vehicle speed is detected using the wheel speed sensors.

      • Vehicle speed data is delayed when it is displayed. Therefore, even if the vehicle speed listed in the freeze frame data is 0 km/h (0 mph), this does not always mean that the malfunction occurred when the vehicle was stopped.

      Engine Speed

      Engine speed/

      Min.: 0 rpm

      Max.: 16383 rpm


      • 0 rpm: Engine stopped (ignition switch ON)

      • After warming up the engine, the engine coolant temperature is 80 to 100°C (176 to 212°F).

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

  2. 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.
