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.
