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.

Meaning of fuel system loop status
- The following information is displayed on the tester.
- Feedback stops: ECT is lower than the determined feedback zone.
- Feedback operating: HO2S being used for feedback is normal.
- Feedback stops: Open loop due to driving condition
- Feedback stops: Open loop due to detected system fault
- Feedback operating: Malfunction occurred in HO2S (rear) system
