- Sebenzisa i- PHEZULU/PHANSI arrows to scroll through different data parameters.
- Sebenzisa i- KWESOKUNXELE/KUSELE arrows to switch between text and graph views (if available for the parameter).
3.2.4 Friza Idatha Yozimele
When an emission-related fault occurs, the vehicle's computer records a snapshot of operating conditions at the time of the fault. This "freeze frame" data helps in diagnosing intermittent problems.

Umfanekiso 3.5: View Freeze Frame and DTCs. This image displays the scanner's ability to capture and show freeze frame data, which provides a snapshot of engine conditions at the moment a fault code was set, aiding in diagnosis.
- Khetha "View Freeze Frame" from the Diagnosis menu.
- Review the recorded parameters.
3.2.5 DTC Query (DTC Lib)
The built-in DTC Library allows you to look up definitions for generic (P0, P2, P34, B0, C0, U0) and manufacturer-specific (P1, P30-P33, B1, C1, U1) codes.
- From the main menu, select "DTC Lib".
- Enter the DTC code using the arrow keys and OK inkinobho.
- The scanner will display the definition of the code.
