Freeze Frame
In most cases the stored frame is the last DTC that occurred. Certain DTCs, which have a
greater impact on vehicle emission, have a higher priority. In these cases, the top prioritized
DTC is the one for which the freeze frame records are retained. Freeze frame data includes a
“snapshot” of critical parameter values at the time the DTC is set.
