TOPDON spans entry-level code readers, phone-powered Bluetooth scanners, handheld multi-system tools, and OE-level bidirectional tablets. The right choice depends on what you drive, which systems you touch, and whether you need coding or J2534 reprogramming.
Entry Level: Code Readers (AL400, CarPal)
Best for check-engine light diagnostics, smog readiness, and live engine data. No ABS, SRS, or transmission access. Lowest cost, fastest learning curve. Ideal if you only need to know why the MIL is on.
Bluetooth Scanners (TopScan Lite, Pro, Master)
Turn your smartphone into a scan tool. TopScan Lite adds all-system bi-directional scans, eight service resets, CAN-FD, and FCA AutoAuth — remarkable capability for a dongle. Step up to Pro or Master for deeper active tests and broader reset lists.
Handheld Multi-System (AD500, AD600S, ArtiDiag600 Pro)
Dedicated devices with screens — no phone required. AD500 covers engine, ABS, SRS, and transmission on supported models with five-plus service resets. ArtiDiag600 Pro adds bi-directional active tests and Wi-Fi updates for serious home garages.
Professional Bidirectional (AD800BT 2, AD900BT, Phoenix)
Active tests, ECU coding on supported platforms, topology views, and multi-year updates. Phoenix Plus 2 adds OE-level online coding and optional J2534. Choose this tier if you run a shop or perform module replacement and adaptation work.
Decision Checklist
- Engine codes only → AL400 or CarPal US

- Handheld ABS/SRS/transmission → AD500 or AD600S
- Bi-directional + FCA → AD800BT 2
- OE coding / J2534 → Phoenix Plus 2 or TOPDON One
