Freeze Frame Data

  1. FREEZE FRAME DATA 
    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 ignition switch has been turned from off to ON since the last time the ABS was activated.

      HINT:

      • If the vehicle is stopped, 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 of times the ignition switch has been turned from off to ON.
      • 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 cleared.

      • 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 
    1. Connect the Techstream to the DLC3.
    2. Turn the ignition switch to ON.
