Sfi System -- Freeze Frame Data



DESCRIPTION
  1. The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data can be helpful in determining whether the vehicle was moving or stationary, whether the engine was warmed up or not, whether the air fuel ratio was lean or rich, as well as other data recorded at the time of a malfunction.
    HINT:
    If it is impossible to replicate the problem even though a DTC is output, confirm the freeze frame data.

    The ECM records engine conditions in the form of freeze frame data every 0.5 seconds. Using the GTS, 5 separate sets of freeze frame data, including the data values at the time when the DTC is stored, can be checked.
    1. 3 data sets before the DTC is stored.
    2. 1 data set when the DTC is stored.
    3. 1 data set after the DTC is stored.
    1. These data sets can be used to simulate the condition 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.

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 GTS to the DLC3.

  2. Turn the ignition switch to ON.

  3. Turn the GTS 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:
    1. Pending freeze frame data is cleared when any of the following occurs.
      1. Using the GTS, the DTCs cleared.
      1. The cable is disconnected from the negative (-) battery terminal.
      1. 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.)
    2. 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.
