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», «History1», «History2», and «History3».
- Time lag between the freeze frame data of «Detect» and the freeze frame data of «History1» 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 «History1» 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 select «Enter».
