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.
Select View Freeze Data and press 
ENTER. A vehicle can store more than 
a DTC.
