WARNING: This page is about a different car, the 2008 Lexus IS F. However, it is still accessible from the selected car via links, so may be relevant.
  1. DATA LIST 

    HINT

    Using the Techstream to read the Data List allows the values or states of switches, sensors, actuators and other items to be read without removing any parts. This non-intrusive inspection can be very useful because intermittent conditions or signals may be discovered before parts or wiring is disturbed. Reading the Data List information early in troubleshooting is one way to save diagnostic time

    1. Connect the Techstream to the DLC3.
    2. Turn the engine switch on (IG)
    3. Enter the following menus Body Electrical / Mirror L/Mirror R / Data List.
    4. According to the display on the Techstream, read the Data List
