Buying Guide
Diagnostic Coverage: Full Systems vs. Basic Codes
Not all scanners are created equal. Basic code readers only pull engine codes, while full-system diagnostic tools can access the ABS, SRS, transmission, and more. For a complete health check, you want a tool that scans every module. The TOPDON ArtiDiag600 Pro, for example, offers full-system coverage, which is essential for uncovering hidden faults.
If you are a professional, consider a bidirectional scan tool that can also command components. The TOPDON TopScan Pro lets you run active tests on windows, injectors, and cooling fans. This capability is a game-changer for pinpointing issues quickly. For more on this, see our best bidirectional scan tool guide.
Service Functions and Resets
Modern vehicles require maintenance resets like oil reset, brake pad replacement, and steering angle sensor calibration. The more service functions a scanner has, the more you can do at home. The TOPDON ArtiDiag600 Pro offers 9 essential resets, while the TopScan Pro boasts 13+. For heavy-duty trucks, the ArtiDiag HD provides 10 services tailored to diesel systems.
Think about the vehicles you work on. If you own a late-model European car, look for a tool with FCA or SGW gateway access. The ArtiDiag Pro, for instance, supports FCA AutoAuth, which is crucial for Chrysler, Jeep, Dodge, and Fiat models. Always verify compatibility with your specific vehicle before purchasing.
Ease of Use and Connectivity
Gone are the days of clunky, cable-bound scanners. Many modern tools are wireless and pair with your smartphone via Bluetooth. The TOPDON TopScan Pro works with both iOS and Android, giving you a sleek, portable solution. For handheld units like the ArtiDiag600 Pro, a touchscreen interface and intuitive menus are key.
Also, consider how updates are handled. Lifetime free updates are a huge plus, as they keep your scanner compatible with new vehicle models. The ArtiDiag600 Pro offers OTA updates via Wi-Fi, so you never need a computer. For a deep dive into wireless options, check our best Bluetooth OBD2 scanners roundup.
