Freeze Frame Data

  1. FREEZE FRAME DATA 
    1. The vehicle (sensor) status, stored during ABS and/ or VSC operation or at the time of an error code detection, can be displayed by the intelligent tester.
    2. Only one record of freeze frame data is stored and the freeze frame data generated during ABS and/or VSC operation are updated whenever the vehicle status is changed. Also, the number of the ignition switch is ON after the freeze frame data is stored can be stored up to 31 and it can be displayed. After storing the DTC, the freeze frame data is not updated.

      HINT:

      If the ignition switch "ON" operation exceeds 31 times, "31 "appears on the display.

    3. If a malfunction occurs, the freeze frame data is stored but the ABS actuation data is deleted.
