Freeze Frame Data [08/2019 - ]

  1. FREEZE FRAME DATA/INFORMATION 
    1. Whenever an ABS, VSC or electronically controlled brake system DTC is detected, the skid control ECU assembly stores the current vehicle (sensor) state as Freeze Frame Data.
    2. The skid control ECU assembly stores the number of times (maximum: 31) the power switch has been turned from off to on (IG) since the last time the ABS was activated.
    3. For DTCs stored in the skid control ECU assembly, information (INF) codes that are contained in the Freeze Frame Data can be displayed on the Techstream.

      HINT: 

      • If the vehicle is stopped or driven at a low speed (7 km/h (4.3 mph) or less), or if a DTC is detected, the skid control ECU assembly will stop counting the number of times the power switch has been turned from off to on (IG).
      • Freeze Frame Data at the time the ABS operates:

        The skid control ECU assembly stores and updates data whenever the ABS system operates.

        When the ECU stores data at the time a DTC is detected, the data stored during ABS operation is cleared.

      • Freeze Frame Data at the time a DTC is detected:

        When the skid control ECU assembly stores data at the time a DTC is detected, no updates will be performed until the data is cleared.

  2. CHECK FREEZE FRAME DATA AND INFORMATION 
    1. Connect the Techstream to the DLC3.
    2. Turn the power switch on (IG).
    3. Turn the Techstream on.
    4. Enter the following menus: Chassis / ABS/VSC/TRAC / Trouble Codes.

      Chassis > ABS/VSC/TRAC > Trouble Codes 

    5. Read the Freeze Frame Data recorded when the DTCs were stored.
    6. Read the information.
      1. Select the item that has an information code (INF code) from the Freeze Frame Data screen.

  3. CLEAR FREEZE FRAME DATA AND INFORMATION 
    NOTE:

    Clearing the DTCs will also clear the Freeze Frame Data and information codes (INF codes).

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

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