Data List / Active Test [10/2017 - 09/2019]

WARNING: This page is about a different car, the 2020 Lexus LS 500h, 2019 Lexus LS 500h, and 2018 Lexus LS 500h. However, it is still accessible from the selected car via links, so may be relevant.
  1. DATA LIST 
    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.

    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. Turn the power switch off.
    2. Connect the Techstream to the DLC3.
    3. Turn the power switch on (IG).
    4. Turn the Techstream on.
    5. Enter the following menus: Body Electrical / Vehicle Proximity Notification System / Data List.
    6. Read the Data List according to the display on the Techstream.

  2. ACTIVE TEST 

    HINT: 

    Using the Techstream to perform Active Tests allows relays, VSVs, actuators and other items to be operated without removing any parts. This non-intrusive functional inspection can be very useful because intermittent operation may be discovered before parts or wiring is disturbed. Performing Active Tests early in troubleshooting is one way to save diagnostic time. Data List information can be displayed while performing Active Tests.

    1. Turn the power switch off.
    2. Connect the Techstream to the DLC3.
    3. Turn the power switch on (IG).
    4. Turn the Techstream on.
    5. Enter the following menus: Body Electrical / Vehicle Proximity Notification System / Active Test.
    6. Perform the Active Test according to the display on the Techstream.

      Body Electrical > Vehicle Proximity Notification System > Active Test
