Display Of Engine Freeze Frame Data
NOTE:
- ECM captures the freeze frame data every 0.5 seconds and always keeps the latest three cords. Time-series freeze frame data includes the latest 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 "PC application help for Subaru Select Monitor".
- A list of the support data is shown in the following table.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
