СИСТЕМА АВТОМАТИЧЕСКОЙ ТРАНСМИССИИ С ЭЛЕКТРОННЫМ УПРАВЛЕНИЕМ РЕЖИМЫ DATA LIST / ACTIVE TEST


  1. DATA LIST

    Tech Tips

    Using the Intelligent Tester Data List allows switch, sensor, actuator and other item values to be read without removing any parts. Reading the Data List early in troubleshooting is one way to shorten labor 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 Intelligent Tester to the DLC3.

    4. Turn the ignition switch to the ON position.

    5. Turn on the tester.

    6. Select the item "Enter / Power train / Engine and ECT / Data List".

    7. Follow the instructions on the tester and read the Data List.

      Tech Tips


      • Lock-up ON (warmed up engine, other than O/D):

        Input Turbine Speed (NCO) is equal to engine speed

      • Lock-up ON (warmed up engine, O/D):

        Input Turbine Speed (NCO) is 0 rpm

      • Lock-up OFF (Idling with shift lever on N):

        Input Turbine Speed (NCO) is nearly equal to engine speed

  2. ACTIVE TEST

    Tech Tips

    Performing the Intelligent Tester Active Test allows relay, Vacuum Switching Valve (VSV), actuator and other items to be operated without removing any parts. Performing the Active Test early in troubleshooting is one way to shorten labor time. The Data List can be displayed during the Active Test.


    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 the ON position.

    5. Turn on the tester.

    6. Select the item "Enter / Power train / Engine and ECT / Active Test".

    7. Follow the instructions on the tester and read the Active Test.

      Item Test Details Diagnostic Note
      Control the Shift Position

      [Test Details]

      Operate the shift solenoid valve and set each shift position by yourself.

      [Vehicle Condition]

      Less than 50 km/h (31 mph)

      [Others]


      • Press "→" button: Shift up

      • Press "←" button: Shift down

      		 Possible to check the operation of the shift solenoid valves.
      Control the Lock Up

      [Test Details]

      Control the shift solenoid SL to set the automatic transmission to the lock-up condition.

      [Vehicle Condition]


      • Throttle valve opening angle: Less than 35%

      • Vehicle Speed: 60 km/h (37 mph) or more

      		 Possible to check the SL operation.
      Control the Line Pressure Up *

      [Test Details]

      Operate the shift solenoid SLT and raise the line pressure.

      [Vehicle Condition]


      • Vehicle Stopped.

      • IDL: ON

      Tech Tips

      OFF: Line pressure up (When the active test of "Control the Line Pressure Up" is performed, the ECM commands the SLT solenoid to turn off).

      ON: No action (normal operation)

      		 -

      *: "Control the Line Pressure Up" in the ACTIVE TEST is performed to check the line pressure changes by connecting the SST to the automatic transmission, which is used in the HYDRAULIC TEST Click here as well.

      Tech Tips

      The pressure values in ACTIVE TEST and HYDRAULIC TEST are different from each other.
