ECM obtains freeze frame data every 0.5 seconds. When DTC is detected, freeze frame data of [Detect], [1 before], [two blocks before] and [three blocks before] is saved. (Time series freeze frame data)
NOTE:
- 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.
