Autel AutoLink AL629 ABS/SRS/Engine/Transmission Code Reader

Autel AutoLink AL629 is a versatile diagnostic and code reader combining full OBDII/EOBD engine diagnostics with manufacturer-specific diagnostics for four key vehicle systems: engine, transmission, ABS, and SRS/airbag.

The AL629 is an excellent choice for professional workshops and advanced DIY users requiring more functionality than a basic OBDII code reader without moving to a full-size diagnostic tablet.

The tool connects directly to the vehicle's OBDII diagnostic port and is powered by the vehicle. Its 2.8” color display, straightforward interface, and dedicated One-Click I/M Readiness button make everyday diagnostic work fast and easy.
