Data List/Active Test

  1. READ DATA LIST 

    HINT:

    Using the hand-held 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 hand-held tester to the CAN VIM. Then connect the CAN VIM to the DLC3.
    4. Turn the ignition switch ON.
    5. Turn the hand-held tester ON.
    6. Enter the following menus: DIAGNOSIS / ENHANCED OBD II / DATA LIST.
    7. According to the display on tester, read the DATA LIST.

    HINT:

    • If no conditions are specifically stated for "idling", the shift lever is in the N or P position, and the A/C and all accessory switches are OFF.
    • *: Misfire margin indicates the possibility that misfires do not occur. The misfires are counted when the misfire margin is 0 % or less. Misfires are unlikely to occur if the misfire margin is more than 30 %. Misfire margin is calculated with the following arithmetic expression.

    • PERFORM ACTIVE TEST 

      HINT:

      Performing the hand-held tester's 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 save time. The DATA LIST can be displayed during the ACTIVE TEST.

      1. Turn the ignition switch OFF.
      2. Connect the hand-held tester to the CAN VIM. Then connect the CAN VIM to the DLC3.
      3. Turn the ignition switch ON.
