What is freeze frame data of obd diagnostic tool?

We often see freeze frame data in the support function of car diagnostic tool. So what is freeze frame data? What's the use?

Freeze frame is relative to the vehicle emission system. When there is an emission related fault, ECU will set the fault code and record the vehicle running status information. ECU record the information at the moment of fault occurrence to confirm the fault. These recorded information is freeze frame.

What is the function of freeze frame? When the OBD diagnostic system detects the abnormality of the vehicle that affects the emission, it will record the DTC and freeze frame. The freeze frame data can be read by obd diagnostic tool. The freeze frame data records the running state of the vehicle when the abnormality occurs (such as speed, engine speed, temperature, etc.). So during the reparation, user can know the abnormal position and the cause by using car diagnostic tool. Freeze frame can make the diagnosis faster and more accurate.

We know that when the fault code appears, eobd diagnostic tool can clear the fault code after troubleshooting. So can car diagnostic tool delete the freeze frame data? According to what Fiberall knows, the freeze frame data will always be with ECU. Even if the obd2 diagnostic tool clear relevant historical fault code, the freeze frame data will still exist in the ECU.

The above is the introduction of freeze frame data supported by car diagnostic tools. And we can see that freeze frame data is very helpful for obd diagnostic tool to play a better role.
