Autel MaxiCOM MK808S — bidirectional tablet scanner
$378.95★4.7 (3,878 ratings)Check fit for your model
OUR VERDICT
The only genuinely bidirectional tool we evaluated: the MK808S reads every major module (engine, transmission, ABS, TPMS, BCM), runs 3,000+ active component tests and handles 28+ reset services on a dedicated Android tablet. Overkill for a check-engine light, right at home for a serious DIYer or side-shop. Note this is the S revision — the original MK808 is the older, shallower tool and is what most stale round-ups still link.
WHY IT WINS
3,000+ bidirectional active tests plus OE-level all-system diagnostics
28+ reset services including oil, ABS bleed, SAS calibration and BMS registration
Standalone 7-inch Android tablet — no phone or laptop needed

Buy on AmazonThe most-reviewed scanner in the category by a wide margin, and the app is why: enhanced ABS/SRS/airbag reads plus vehicle-specific Repair Reports drawn from a database of verified fixes. The dongle needs your phone, so there's no standalone screen.
