Freeze-Frame Data
Freeze-frame data provides a snapshot of conditions present when an emission-related DTC is stored. Once one set of freeze-frame data is stored, this data will remain in memory, even if another emission-related DTC is stored, with the exception of misfire or fuel system DTCs. Once freeze-frame data for a misfire or fuel system DTC is stored, it will overwrite any previous freeze-frame data, and will not be further overwritten.
