Freeze Frame Data [11/2021 - ]
- 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.
HINT:
- 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.
- When performing diagnosis, you can utilize the Freeze Frame Data to guess the vehicle status when the DTC was detected.
*A First detected DTC *B Second detected DTC *C Third detected DTC or later *D Current *E Past *F Time series Freeze Frame Data - TIME SERIES FREEZE FRAME DATA
ECM obtains Freeze Frame Data every 0.5 seconds. When DTC is detected, Freeze Frame Data of [Detect], [1before], [History2] and [History3] is saved. (Time series Freeze Frame Data)
HINT:
You can utilize the time series Freeze Frame Data for diagnosis by checking the status of data changes three times earlier than the DTC was detected.
*A [Detect] *B [1 before] *C [History2] *D [History3] *E Current *F Past *G 0.5 sec. - - - LIST
