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) (H4DO)>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 (DIAGNOSTICS)>FREEZE FRAME DATA>OPERATION .
