DYNAMIC TORQUE CONTROL AWD SYSTEM FREEZE FRAME DATA


  1. FREEZE FRAME DATA


    1. When a DTC is stored, the 4WD ECU assembly stores the current vehicle state as Freeze Frame Data.

      Tech Tips

      Freeze Frame Data at the time a DTC is stored:


      • When the 4WD ECU assembly stores data at the time a DTC is stored, no updates will be performed until the data is cleared.

      • "Number of IG ON" is not stored as 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 / Four Wheel Drive / Trouble Codes.


      Chassis > Four Wheel Drive > Trouble Codes

    5. According to the display on the GTS, select the trouble code data display with Freeze Frame Data.
