Freeze Frame
When the signal of the sensor is abnormal, the ECU will save the data
at that moment of failure to form a freeze frame. It is usually used to
analyze the reasons that may lead to car failures.
The living data items supported by vehicles of different brands are not
exactly the same, so the freeze frames displayed when diagnosing
vehicle of different brands may also be different. Some vehicles may
not have the option of freeze frame which means that the model does
not support this function.
