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.
- When more than one DTCs are recorded, the time-series freeze frame data is recorded only for the first-detected DTC, and for the next DTC, just the freeze frame data of «Detect» is recorded. And for the subsequent DTCs, no freeze frame data is recorded.
- When performing diagnosis, you can utilize the time-series freeze frame data to guess the vehicle status when the DTC was detected.
- For detailed operation procedures, refer to "Application help".
- A list of the support data is shown in the following table.
- On «Start» display, select «Diagnosis».
- On «Vehicle selection» display, input the vehicle information and select «Confirmed».
- On «Main Menu» display, select «Each System».
- On «Select System» display, select «Engine Control System» and then select «Enter».
- On «Select Function» display, select «DTC» and then select «Enter».
