② Live Data Display
Multi-Parameter Viewing
View up to 12 live parameters simultaneously for easier comparison. Sorting and grouping options allow technicians to analyze sensor behavior and system performance with clarity during diagnostic work.

The TOPDON ONE Lite generates structured diagnostic reports that include fault codes, module status, and test results. Save and share reports with customers or internal teams for documentation and repair planning.

6. Add-On Tools & Software Renewal
