Freeze Frame Data

  1. FREEZE FRAME DATA/INFORMATION 
    1. Whenever an ABS DTC is detected, the skid control ECU stores the current vehicle (sensor) state as Freeze Frame Data.
    2. The skid control ECU 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 memorized in the skid control ECU, information (INF) codes that are contained in the Freeze Frame Data can be displayed on Techstream.

      HINT:

      • However, if the vehicle is stopped or at a low speed (7 km/h (4.3 mph) or less), or if a DTC is detected, the skid control ECU will stop counting the number.
      • Freeze Frame Data at the time the ABS operates:

        The skid control ECU 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 erased.

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

      When the skid control ECU 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 Techstream to the DLC3.
    2. Turn the power switch on (IG).
    3. On the tester display, select the Freeze Frame Data.
    4. Read the Freeze Frame Data recorded when the DTC was set.
    5. Read the information.
      1. Select the item that has an information (INF) code from the Freeze Frame Data screen.
