Data List/Active Test

  1. READ DATA LIST 

    HINT:

    Using the intelligent tester's 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 save time.

    NOTE: In DATA LIST DETAIL  , 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 CAN VIM. Then connect the CAN VIM to the DLC3.
    4. Turn the ignition switch ON.
    5. Turn the intelligent tester ON.
    6. Enter the following menus: DIAGNOSIS / ENHANCED OBD II / DATA LIST.
    7. Follow the instructions on the tester and read the DATA LIST.

    4. Turn the ignition switch ON.
    5. Turn the tester ON.
    6. Enter the following menus: DIAGNOSIS / ENHANCED OBD II / ACTIVE TEST.
    7. Perform the ACTIVE TEST.

      • Press "<--" button: Shift down
      		 Possible to check operation of shift solenoid valves
      LOCK UP [Test Details]
      Control shift solenoid SLU to set automatic transmission to the lock-up condition
      [Vehicle Condition]
      • Throttle valve opening angle: Less than 35%

      		 Possible to check shift solenoid SLU operation
      LINE PRESS UP * [Test Details]
      Operate shift solenoid SLT and raise line pressure

      • IDL: ON

      HINT:

      HINT:

      *: "Control the Line Pressure Up" in the ACTIVE TEST is performed to check the line pressure changes by connecting SST to the automatic transmission, which is used in the HYDRAULIC TEST (see HYDRAULIC TEST  ) as well. Please note that the pressure values in the ACTIVE TEST and HYDRAULIC TEST are different.
