View Freeze Data

When an emission-related fault occurs, certain vehicle conditions are recorded by the on-board computer. This information is referred to as a Freeze Frame data. The information is a “snapshot” of the operating conditions at the time of a fault. This data can be overwritten by faults with a higher priority.

✓Only one Freeze Frame can be kept per module. Switching from Engine to Transmission will overwrite Data. Make sure to print data before selecting a diffrent module.

✓If codes were erased, then freeze frame data may not be stored in vehicle memory.
