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.

- 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.
