About it
The Autel MaxiLink ML629 is a four-system OBD2 diagnostic scanner and the upgraded successor to the ML619. It reads and clears fault codes across the engine, transmission, ABS, and SRS airbag systems, giving a complete picture of vehicle health in a single tool. For engine diagnostics, the ML629 retrieves and erases Diagnostic Trouble Codes, displays freeze frame data, and monitors live sensor data to pinpoint check engine light issues. Transmission diagnostics access control module data to identify shifting problems, slipping, and other drivetrain faults. SRS airbag diagnostics read and clear airbag fault codes for safety system repairs and post-collision inspections. ABS diagnostics diagnose anti-lock braking system faults and clear ABS warning lights. The scanner supports all ten standard OBD2 test modes, including DTC read and clear, I/M readiness checks, oxygen sensor testing, on-board monitor testing, EVAP system testing, and vehicle information retrieval. It is compatible with all 1996 and newer OBD2-compliant vehicles, including cars, SUVs, light trucks, and minivans from major US, European, and Asian manufacturers. Freeze frame data captures the exact engine conditions recorded when a fault code was triggered, which is useful for diagnosing intermittent issues. The real-time live data stream lets you monitor multiple sensor parameters simultaneously in graph or text format to verify that repairs worked. AutoVIN technology automatically identifies the vehicle by reading the VIN, eliminating manual entry. A built-in DTC lookup library provides plain-English definitions for thousands of fault codes without an internet connection. Free lifetime software updates via USB keep the tool current with the latest vehicle coverage and DTC definitions. The package includes the Autel MaxiLink ML629 scanner, an OBD2 cable, a USB cable, and a quick reference guide.

1
Autel AutoLink AL319 OBD2 Code Reader
Reads and clears engine codes, shows live data and freeze frame, and checks emissions readiness. It powers from the port, so it lives in the glovebox.

3
Autel MaxiCheck MX900 Bidirectional Scan Tool
A bidirectional scan tool: it sends commands to the car's modules, so a part can be tested from the scanner instead of only read about.
