Freeze Frame Data

WARNING: This page is about a different variant/trim than selected.

OBD-II or Toyota hand-held tester can by used to check freeze frame data. ECM records engine operating condition when a misfire, fuel trim (mixture) malfunction or other malfunction (fuel system, calculated load, coolant temperature, fuel trim (mixture), engine speed, vehicle speed, etc.) exists. If more than one DTC is detected, only data from the first malfunction is recorded. Recorded data is useful for determining conditions during which the malfunction occurred.
