Freeze Frame Data [09/2020 - 11/2021]

  1. FREEZE FRAME DATA 
    1. Using the Techstream, 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 

    HINT: 

    • Freeze frame data is stored when a DTC is output.
    • Once freeze frame data is stored when a DTC is output, it is not updated or cleared until the DTC is cleared.
    1. Turn the engine switch off.
    2. Connect the Techstream to the DLC3 and turn the engine switch on (IG).
    3. Enter the following menus: Chassis / Brake/EPB / Trouble Codes.

      Chassis > Brake/EPB > Trouble Codes 

    4. Select a DTC to display the freeze frame data.
    5. Check the freeze frame data for the output DTC.
