Turn your phone into a pro-grade car scanner

The TOPDON TopScan Pro is a Bluetooth OBD2 scanner that transforms your smartphone into a professional diagnostic tool. Plug the compact dongle into your car’s OBD2 port, pair it with the free TOPDON app on iOS or Android, and you have a whole diagnostic bay in your pocket — no bulky tablet required.

What it does

• Full-system diagnostics — read & clear codes across Engine, ABS, SRS/airbag, transmission and more.
• Bi-directional control & active tests — command components straight from your phone.
• 13+ reset services — Oil, EPB, BMS, SAS, throttle relearn and other maintenance resets.
• Live data & AI repair guidance — graph real-time sensor data and get smart, step-by-step fix suggestions.
• I/M Readiness & Smog pre-check — know if you’ll pass before you drive to the testing station.
• Works with iOS & Android — wireless, pocket-sized, and updated regularly.

Who it’s for

Whether you’re a weekend DIYer chasing a check-engine light or a busy tech who wants a grab-and-go scanner, the TopScan Pro delivers shop-level features at a fraction of the price of a standalone scan tool.
