Freeze Frame Data

2007 Lexus ES 350SECTION 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 engine switch has been turned from off to on (IG) since the last time the ABS was activated.

      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 
    1. Connect the intelligent tester to the DLC3.
    2. Turn the engine switch on (IG).
    3. On the tester display, select the Freeze Frame Data.
