Freeze Frame Data Monitor Table
- Retrieve the following FFD.

NOTE: FFD is a snapshot of the conditions that are present when DTC or PENDING CODE is stored. Once FFD is stored, this data will remain in PCM memory even if another emission related DTC or PENDING CODE is stored additionally, except for Misfire or Fuel System related DTC or PENDING CODE. Once Misfire or Fuel System related DTC or PENDING CODE is stored, it will overwrite any previous data and the FFD will not be further overwritten. When DTC associated with the FFD is erased or PCM is reset, new FFD can be stored.
