When an emission-related fault occurs, the vehicle's computer records a snapshot of operating conditions at the time of the fault. This data is called Freeze Frame data.
- Из главног менија изаберите 'Diagnose'.
- Изаберите 'Freeze Frame'.
- Review the recorded parameters to understand the conditions under which the fault occurred.
4.6 ДТЦ тражење

This feature allows you to manually enter a Diagnostic Trouble Code and view its definition from the scanner's internal database.
