Freeze-frame data can record values such as engine speed, load, temperature, and vehicle speed around the time a diagnostic trouble code set. Save it before clearing codes or disconnecting the battery.
It is a snapshot, not a full recording and not proof of a failed part. Compare the values with what the car was doing, then use the vehicle-specific diagnostic steps to test the likely system.
Quick educational note
For information, not a diagnosis or repair instruction. Vehicle-specific checks are still required. Consult the manufacturer's guidance and a qualified technician.
