Freeze Frame Data

  1. FREEZE FRAME DATA 

    HINT:

    • Whenever a DTC is detected or the ABS operates, the skid control ECU stores the current vehicle (sensor) state as freeze frame data.
    • The skid control ECU stores the number of times (maximum: 31) the power switch has been turned from OFF to the ON (IG or READY) position since the last time ABS was activated. However, if the vehicle was stopped or at low speed (4.3 mph (7 km/h) or less), or if a DTC is detected, the skid control ECU will not count the number since then.
    • 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 when the ABS operated 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.
    1. Connect the Teachstream to the DLC3.
    2. Turn the power switch ON (READY).
    3. From the display on the tester, select the FREEZE FRAME DATA.
