Data List / Active Test

  1. 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 or the OBD II scan tool to the DLC3.
    4. Turn the ignition switch ON.
    5. Turn ON the intelligent tester.
    6. Enter the following menus: DIAGNOSIS / ENHANCED OBD II / DATA LIST.
    7. According to the display on tester, read the "DATA LIST".
