Data List / Active Test

WARNING: This page is about a different car, the 2007 Lexus SC 430. However, it is still accessible from the selected car via links, so may be relevant.
  1. READ DATA LIST 

    HINT:

    Using the intelligent tester's DATA LIST allows switch, 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. Connect the intelligent tester to the DLC3.
    2. Turn the ignition switch ON.
    3. Read the DATA LIST according to the display on the tester.
