Autel MaxiCOM MK808S: What to Know
The MK808S reads and clears DTCs across all available modules on most makes and models, and, unlike every other product in this guide, is a true bidirectional scanner: Autel states support for 3,000-plus active tests, meaning it can send commands to actuate components (cycling a fuel injector, activating an ABS pump, and similar) rather than just reading data from them. That's a meaningfully different, and more advanced, capability than anything else covered here, including the TOPDON ArtiDiag600S's functional resets.
It's a standalone 7-inch touchscreen tablet-style device (1024x600 resolution) with dual-band Wi-Fi for updates and cloud storage, though it still requires a wired connection to the vehicle's OBD2 port to actually run diagnostics, Wi-Fi here is for software updates, not vehicle communication.
This is the real, documented subscription caveat for the OBD2 scanner category, and it applies squarely to the MK808S: Autel includes one year of free software updates with purchase, after which continued updates require a paid renewal. Reseller listings for the closely related MK808/MK808S update service put that renewal in roughly the $85-$140 per year range, though Autel's own product page for the MK808S doesn't clearly post that price itself, a gap worth flagging honestly rather than glossing over, since it's a real ongoing cost buyers should budget for.
Autel's Amazon listing claims coverage for 200-plus car brands with 28-plus special service functions and FCA AutoAuth/SGW (secure gateway) support for newer Fiat-Chrysler-group vehicles, among the broadest stated coverage in this guide, though exactly which active tests and functions work on a given specific model still varies by vehicle and isn't spelled out in full on the manufacturer page. A current product photo for this exact listing could not be independently confirmed as resolving during this research pass, so no image is shown pending confirmation.
