TOPDON TopScan turns your smartphone into a diagnostic terminal. The Lite and Pro dongles share the same app ecosystem but differ in active-test depth, reset count, and vehicle coverage tiers.
TopScan Lite
All-system bi-directional scans, eight service resets, AI repair guides, CAN-FD, and FCA AutoAuth — exceptional value for driveway mechanics. If you own one vehicle family and need pro features without a tablet, Lite is the default recommendation.
TopScan Pro
Expands bi-directional routines and reset coverage for users who outgrow Lite — more active tests on supported platforms, broader module depth, and enhanced vehicle lists. Worth the upgrade if Lite lacks a specific reset or active test for your daily driver.
TopScan Master
Flagship Bluetooth dongle with maximum TopScan coverage and 2026 wireless enhancements. Consider Master if Pro still misses functions on your vehicles or you run a mobile workflow and need every TopScan capability.
Phone and Vehicle Compatibility
Confirm Bluetooth support on your phone OS version. CAN-FD matters for 2019+ vehicles. FCA/Stellantis owners should verify AutoAuth coverage for their exact model year before purchase.
