ECD SYSTEM FREEZE FRAME DATA

  1. DESCRIPTION

    The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, and other data from the time the malfunction occurred.

    Tip:

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

    • A286045E01

      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 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 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.
