Display Of Engine Freeze Frame Data
NOTE:
- ECM updates the freeze frame data every 0.5 seconds, and always keeps the last three records. Time-series freeze frame data includes the last three freeze frame data and the freeze frame data when the DTC is detected.
- In the time-series freeze frame data, the following freeze frame data are displayed: «Detect», «1 block before », «2 times past», and «3 times past».
- Time lag between the freeze frame data of «Detect» and the freeze frame data of «1 block before» changes within the range of 0 - 0.5 seconds. This is because the freeze frame data of «Detect» is recorded when the DTC is actually detected, while the freeze frame data of «1 block before» is updated every 0.5 seconds.
