PRE-CRASH SAFETY SYSTEM FREEZE FRAME DATA


  1. FREEZE FRAME DATA


    1. Whenever PCS DTC is detected, the pre-crash safety city sensor stores the current vehicle (ECU or sensor) state as Freeze Frame Data.

      Tech Tips

      The vehicle condition when the DTC was detected is stored as the freeze frame data.

  2. CHECK FREEZE FRAME DATA


    1. Connect the GTS to the DLC3.

    2. Turn the ignition switch to ON.

    3. Turn the GTS on.

    4. Enter the following menus: Chassis / PCS/LDA/RSA/LVN /Trouble Codes.

    5. According to the GTS display, select a DTC that stored freeze frame data.

    6. Read the freeze frame data recorded when the DTC was stored.
