Data List/Active Test

  1. DATA LIST 

    HINT:

    Using the hand-held 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 Fig 1 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 hand-held tester to the Controller Area Network Vehicle Interface Module (CAN VIM). Then connect the CAN VIM to the Data Link Connector 3 (DLC3).
    4. Turn the ignition switch ON.
    5. Turn ON the hand-held tester.
    6. Enter the following menus: DIAGNOSIS/ ENHANCED OBD II/ DATA LIST.
    7. According to the display on tester, read the DATA LIST.
