Viewing Freeze Frame Data
Freeze Frame Data
allows the technician to view the vehicle’s
operating parameters at the moment a DTC (Diagnostic Trouble
Code) is detected. For example, the parameters may include engine
speed (RPM), engine coolant temperature (ECT), or vehicle speed
sensor (VSS) etc. This information will aid the technician by
allowing the parameters to be duplicated for diagnostic and repair
purposes.
