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 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 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.

      • OFF: Line pressure up (when Active Test "LINE PRESS UP" is performed, ECM commands SLT solenoid to turn OFF)
      • ON: No action (normal operation)
      [Vehicle Condition]
      • Vehicle stopped
      • Engine: idling
      LOCK UP Control shift solenoid SLU to set automatic transmission to lock up condition ON or OFF Possible to check shift solenoid valve SLU operation
      [Vehicle Condition]
      • Throttle valve opening angle: Less than 35%
      • Vehicle speed: 60 km/h (36 mph) or more
      SHIFT Operate shift solenoid valve and set each shift position by yourself
      • Press "→" button: Shift up
      • Press "← button: Shift down

      HINT:
      *: "LINE PRESS 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  as well. Please note that the pressure values in the ACTIVE TEST and HYDRAULIC TEST are different.
