Freeze Frame Data [10/2023 - ]

WARNING: This page is about a different car, the 2024 Lexus LS 500. However, it is still accessible from the selected car via links, so may be relevant.
  1. FREEZE FRAME DATA 
    1. Using the GTS, check the vehicle condition (ECU, sensor) when the brake system operates or a DTC is output.
  2. CHECK FREEZE FRAME DATA WHEN DTC WAS STORED 
    1. Freeze Frame Data is stored when a DTC is output.
    2. Once Freeze Frame Data is stored when a DTC is output, it is not updated or cleared until the DTC is cleared.
    3. Check the Freeze Frame Data when a DTC is output.
      1. Turn the ignition switch off.
      2. Connect the GTS to the DLC3.
      3. Turn the ignition switch to ON.
      4. Turn the GTS on.
      5. Enter the following menus: Chassis / Brake/EPB / Trouble Codes.

        Chassis > Brake/EPB > Trouble Codes 

      6. Select a DTC to display the Freeze Frame Data.
    4. Check the freeze frame data for the output DTC.
