Freeze Frame Data

  1. Check freeze frame data output
    1. Using SSM3, you can check the vehicle (sensor) conditions when an abnormal diagnostic code is stored in memory.
  2. Freeze frame data check when a diagnostic code is stored in memory
    1. If a diagnostic code is output, the freeze frame data at the time of error code occurrence is stored in memory.
    2. When the freeze frame data at the time of diagnostic code occurrence is stored in memory, the data will not be updated or cleared until the memory data is cleared (until the diagnostic code is cleared).
    3. It saves and displays the record, which is up to 31 times of turning IG OFF →ON since the error code has been stored in memory.
      NOTE: The number of turning IG ON exceeds 31, "31" is displayed.
    4. Freeze frame data check when a diagnostic error code is stored in memory
      1. Connect the SSM3 to the DLC3 and turn the ignition to IG ON.
      2. Display the error code on the diagnostic code confirmation screen. (Refer to CHECKING/CLEARING DIAGNOSTIC CODES  )
