Freeze Frame Data

WARNING: This page is about a different car, the 2010 Lexus LS 460L and 2010 Lexus LS 460. However, it is still accessible from the selected car via links, so may be relevant.
  1. FREEZE FRAME DATA 
    NOTE:
    • It is difficult to show the specified values (judgment values) clearly because freeze frame data values change significantly due to differences in measurement conditions, surroundings, or vehicle conditions. For this reason, there may be a problem even when the values are within specifications.
    • Turn the engine switch on (IG) and park the vehicle on level ground. Check the freeze frame data by using the Techstream.
    1. Connect the Techstream to the DLC3.
    2. Turn the engine switch on (IG) and check the freeze frame data by following the prompts on the Techstream's display screen.
