Autel MaxiScan MS309 OBD2 Code Reader

Description

The MaxiScan MS309 is Autel’s compact, handheld OBD2 code reader for everyday check-engine work. Official Autel product information describes a small, cable-connected scanner that works with 1996-and-newer OBD2 vehicles. It reads and clears generic, manufacturer-specific, and pending powertrain codes, displays freeze-frame data captured when a fault is stored, and checks I/M readiness monitors used in emissions testing.

Official Autel materials position the MS309 as a straightforward code reader, not an all-system diagnostic tablet and not an ABS/SRS scanner. There is no large service-reset menu and no module coding. The value is a durable, easy-to-use official Autel instrument for the functions most drivers need when the check-engine light comes on, or when they want to see whether emissions monitors have completed after a repair.

Official specifications

• Designed for 1996-and-newer OBD2-compliant vehicles

This is often the right official Autel tool to keep in a glove box or at the front counter. A shop that already owns a MaxiCOM tablet may still want an MS309 as a quick reader so the main tablet stays on a diagnostic job. Buyers looking up official Autel pages should be careful with numeric Autel.com URLs, because similar legacy paths have been used for other products; the official MS309 page and title should be confirmed.

Who it is for

Choose the MS309 if you need a simple, official Autel check-engine reader at a low price. If you also need ABS and SRS coverage, look at the official AutoLink AL619. If you want all-system diagnostics or service resets, move up to a MaxiAP, MaxiCheck, or MaxiCOM tool and confirm official coverage for your vehicle.
