Freeze Frame Data

  1. DESCRIPTION 
    Fig 1: Identifying Freeze Frame Data
    GTY333806Courtesy of © TOYOTA, LICENSE AGREEMENT TMS1002

    Freeze frame data record the engine conditions (fuel system, calculated load, engine coolant temperature, fuel trim, engine speed, vehicle speed, etc.) when a malfunction is detected. When troubleshooting, it can help determine if the vehicle was running or stopped, the engine was warmed up or not, the air fuel ratio was Lean or Rich, and other data, from the time the malfunction occurred.

    HINT: 

    If it is impossible to replicate the problem even through a DTC is detected, confirm the freeze frame data.

    The ECM records engine conditions in the form of freeze frame data every 0.5 seconds. Using the Techstream five separate sets of freeze frame data, including the data values at the time when the DTC was stored, can be checked.

    • 3 data sets before the DTC was stored.
    • 1 data set when the DTC was stored.
    • 1 data set after the DTC was stored.

    These data sets can be used to simulate the conditions of the vehicle around the time of the occurrence of the malfunction. The data may assist in identifying the cause of the malfunction, and in judging whether it was temporary or not.

  2. PENDING FREEZE FRAME DATA 

    HINT: 

    Pending freeze frame data is stored when a 2 trip DTC is first detected during the first trip.

    1. Connect the Techstream to the DLC3.
    2. Turn the ignition switch to ON.
    3. Turn the Techstream on.
    4. Enter the following menus: Powertrain / Engine and ECT / Trouble Codes.
    5. Select a DTC in order to display its pending freeze frame data.

      HINT: 

      • Pending freeze frame data is cleared when any of the following occurs.
        • Using the Techstream, the DTCs cleared.
        • The cable is disconnected from the negative (-) battery terminal.
        • 40 trips with the engine fully warmed up have been performed after returning to normal. (Pending freeze frame data will not be cleared by only returning the system to normal.)
      • With previous pending freeze frame data stored, if pending freeze frame data is newly stored when a 2 trip DTC is detected in the first trip, the old freeze frame data will be replaced with the new one of the newly detected DTC in the next trip.
