Autel ML629 OBD2 Diagnostic Scan Tool — 4-System Engine, ABS, SRS & Transmission Scanner with Live Data

Designed as an upgrade from basic code readers, the 2026 Autel ML629 combines multi-system fault retrieval with standard OBDII emission checks and a built-in DTC library. It targets DIYers and home mechanics who want faster troubleshooting, I/M readiness checks for smog inspections, and the ability to store, playback or print diagnostic data via a Windows PC. Functions vary by vehicle make, model and year, so confirming compatibility before purchase is recommended.

What systems can the ML629 diagnose on my car?

The ML629 can access four major vehicle systems — Engine (ECM), Transmission (TCM), ABS and SRS — and read/erase their fault codes where that capability is supported. Full read/erase availability depends on the vehicle and model year; live system data beyond OBDII may be limited on some cars.

• Engine/Powertrain DTC read and clear
• Transmission codes and basic retrieval
• ABS wheel-sensor and brake-system code access
• SRS airbag module fault reading and clearing where supported

How does ML629 help with emissions testing and smog readiness?

This scanner runs all 10 OBDII test modes and reports I/M Readiness status so you can verify monitors required for smog checks (misfire, catalyst, O2 sensors, EVAP, etc.). By identifying which monitors are incomplete, you can address the issues before going to a smog station and avoid failing an inspection.

• Reads and clears OBDII codes relevant to emissions
• Displays I/M Readiness and EVAP leak test status
• Shows freeze-frame and VIN data used in inspections
• Graph mode helps spot erratic sensor behavior affecting emissions

What live data and DTC help does the ML629 provide?

The ML629 displays live OBDII sensor data in both text and graph views so you can watch parameters change in real time. It includes a built-in DTC library of over 10,000 definitions for on-device code explanations and allows recording for playback or printing from a Windows computer.

• Live-data streaming for multiple OBDII sensors in text and graph formats
• On-screen DTC descriptions to speed diagnosis
• AutoVIN detection where supported or manual VIN input option
• Data recording, playback and PC printing via Windows-based software

Will the ML629 work on my vehicle model and what support is offered?

ML629 covers OBDII functions for US cars (post-1996), many EU and Asian models, and multi-system diagnostics for numerous brands from roughly 2002–2017. Because function availability is vehicle-specific, Autel recommends providing your VIN or car details to confirm compatibility before ordering.

• OBDII compatibility: US post-1996, EU post-2006, Asian post-2009
• ABS/SRS/Engine/Transmission support across 30+ makes (2002–2016/2017)
• Lifetime free software updates and technical support with device
• 1-year limited warranty plus 30-day replacement or refund option

Who is this for: The Autel ML629 is aimed at home mechanics, independent technicians and car owners who want more than a basic code reader: multi-system diagnostics, I/M readiness checks for smog preparation, live OBDII data graphing, and simple data export for record-keeping. If you need advanced manufacturer-level functions for every system, confirm vehicle compatibility first by sending the car model, year and VIN to Autel support.
