Freeze Frame Data

ECM records the engine status at detection when it detects DTCs. (Freeze frame data) Freeze frame data is recorded on up to a second detected DTC, and not recorded on a third detected DTC and later.

NOTE:

As the freeze frame data is recorded with DTC detected, permanent monitoring cannot be performed.
For the first detected DTC, time series freeze frame data is recorded . Ref. to ENGINE (DIAGNOSTICS) (H4DOTC)>FREEZE FRAME DATA>NOTE>TIME SERIES FREEZE FRAME DATA .
When performing diagnosis, you can utilize the freeze frame data to guess the vehicle status when the DTC was detected.
For detailed operation procedures, refer to "Common (Diagnostics)" . Ref. to COMMON (DIAG)>FREEZE FRAME DATA .
