ELECTRIC PARKING BRAKE SYSTEM FREEZE FRAME DATA


  1. FREEZE FRAME DATA


    • If a DTC is output, the freeze frame data is recorded when the DTC is stored.

    • If freeze frame data is recorded when a DTC is stored, the freeze frame data is not cleared or updated until the stored DTC is cleared.


    1. Using the GTS, the condition of the vehicle (sensors) when the system is operating or when the DTC was stored can be checked.
