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.

    1. Turn the power switch OFF.
    2. Connect the intelligent tester (with CAN VIM) to the DLC3.
    3. Turn the power switch ON (IG) and turn the tester ON.
    4. Check the values by referring to the table below.
