CONTINUOUSLY VARIABLE TRANSAXLE SYSTEM DATA LIST / ACTIVE TEST

  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.

    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.

      Tip:

      • 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

        • Primary / -

        • Engine Control / Engine control system related data

        • Check Mode / Check mode related data

        • AT / Automatic transaxle system related data

        • Vehicle Information / Vehicle information

    7. According to the display on the GTS, read the Data List.

      Diagnostic Note

      Vehicle Speed

      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)

      • No large changes in engine speed: Driving at a constant speed

      When the crankshaft position sensor is malfunctioning, "Engine Speed" is approximately 0 rpm or varies greatly from the actual engine speed.

      MAF

      Airflow rate from mass air flow meter sub-assembly

      Min.: 0 gm/sec.

      Max.: 655.35 gm/sec.

      This is the intake air amount from the mass air flow meter sub-assembly.

      Coolant Temp

      Coolant temperature

      Min.: -40°C (-40°F)

      Max.: 140°C (284°F)

      75 to 100°C (167 to 212°F): After warming up

      • After warming up the engine, the engine coolant temperature is 75 to 100°C (167 to 212°F).

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

      • Check if the engine is overheating if the value indicates 140°C (284°F).

      Throttle Motor DUTY

      Throttle actuator

  2. ACTIVE TEST

    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.
