Freeze Frame Data [09/2020 - ]

WARNING: This page does not describe the selected car, but rather 11 other vehicles, including the 2024 Lexus IS 500, 2024 Lexus IS 350, 2024 Lexus IS 300, 2023 Lexus IS 500, and 2023 Lexus IS 350. However, it is still accessible from the selected car via links, so may be relevant.
  1. DESCRIPTION 
    1. Whenever a front radar sensor system DTC is stored, the millimeter wave radar sensor assembly stores the current vehicle state as Freeze Frame Data.
  2. CHECK FREEZE FRAME DATA 
    1. Select a DTC to display the freeze frame data.

      Body Electrical > Front Radar Sensor > Trouble Codes 

    2. Check the freeze frame data for the output DTC.
  3. FREEZE FRAME DATA CHART
