Autel MaxiLink ML629: The Upgrade You've Been Waiting For

Most basic OBD2 scanners only read engine codes. The Autel MaxiLink ML629 goes further. As the upgraded successor to the ML619, this professional-grade 4-system OBD2 diagnostic scanner reads and clears fault codes across your engine, transmission, ABS, and SRS airbag systems — giving you a complete picture of your vehicle's health in one affordable, easy-to-use tool. Whether you're a DIY car owner or a workshop technician, the ML629 is the smarter way to diagnose.

4-System Diagnostics: Engine, Transmission, ABS & SRS Airbag

The Autel ML629 4-system diagnostic tool goes beyond the check engine light to give you full visibility into the four most critical vehicle systems. Identify the root cause of warning lights fast — without guesswork, without a dealer visit.

Engine Diagnostics

Read and clear engine fault codes (DTCs), view freeze frame data, and monitor live sensor data to diagnose check engine light issues accurately and efficiently.

Transmission Diagnostics

Access transmission control module data to identify shifting issues, slipping, and other drivetrain faults before they become costly repairs.

SRS Airbag Diagnostics

Read and clear SRS airbag fault codes and turn off the airbag warning light — essential for safety system repairs and post-collision inspections.

ABS Diagnostics

Diagnose anti-lock braking system faults and clear ABS warning lights — keeping your vehicle's most critical safety system in top condition.

Full OBD2 Test Modes: Complete Emissions & Engine Coverage

The ML629 supports all 10 standard OBD2 test modes, making it a comprehensive check engine light code reader and emissions diagnostic tool for any 1996 and newer OBD2-compliant vehicle.

• Read & Clear DTCs: Retrieve and erase Diagnostic Trouble Codes across all supported systems.

Freeze Frame Data & Real-Time Live Data Stream

Two of the most powerful diagnostic features in the ML629 — freeze frame data and real-time live data — give you the before-and-after picture you need to diagnose intermittent faults and verify that repairs actually worked.

• Freeze Frame Data: Capture the exact engine conditions recorded at the moment a fault code was triggered — invaluable for diagnosing hard-to-reproduce issues.
• Real-Time Live Data Stream: Monitor multiple sensor parameters simultaneously in graph or text format for fast, accurate fault pinpointing.
