Freeze frame data

  1. Freeze frame data
    NOTE:
    • If an error diagnosis code is output, the freeze frame data at the time of the generation of the error code is recorded.
    • When an error diagnosis code is generated and the freeze frame data is recorded, data is not updated or deleted until the recorded data itself is deleted (diagnosis code deletion).
    1. Turn the ignition switch to OFF.
    2. Connect the SSM3 to the DLC3.
    3. Display the error code on the diagnostic code confirmation screen. (Refer to CHECK LIST FOR INTERVIEW  )
    4. Check the freeze frame data.
