Figure 4-17 Sample of the 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
the same, so the freeze frames displayed when diagnosing vehicles of
different brands may also be different. Some vehicles do not have a
freeze frame option, which means that this model may not support this
feature.
