Freeze Frame Data [08/2019 - ]

  1. FREEZE FRAME DATA 
    1. When a DTC is stored, the 4 wheel drive control ECU stores the current vehicle state as Freeze Frame Data.

      HINT: 

      Freeze Frame Data at the time a DTC is stored:

      When the 4 wheel drive control ECU stores data at the time a DTC is stored, no updates will be performed until the data is cleared.

  2. CHECK FREEZE FRAME DATA 
    1. Turn the engine switch off.
    2. Connect the Techstream to the DLC3.
    3. Turn the engine switch on (IG).
    4. Turn the Techstream on.
    5. Enter the following menus: Powertrain / Four Wheel Drive / Trouble Codes.
    6. According to the display on the Techstream, select the trouble code data display with Freeze Frame Data.

  3. CLEAR FREEZE FRAME DATA 
    NOTE:

    Clearing the DTCs will also clear the Freeze Frame Data.

    1. Turn the engine switch off.
    2. Connect the Techstream to the DLC3.
    3. Turn the engine switch on (IG).
    4. Clear the DTCs and Freeze Frame Data.

      Refer to DTC CHECK / CLEAR [08/2019 - ]
