Autel ML629 OBD2 Scanner Handheld Diagnostic Tool — Engine, Transmission, ABS & SRS, Live Data Graphing

The Autel ML629 is a handheld OBD2 diagnostic scanner that reads and clears codes across Engine, Transmission, ABS and SRS systems while offering full OBDII testing, live data graphing and AutoVIN detection.

If you maintain your own vehicles or run a small shop, the Autel ML629 provides deeper system access than a basic code reader without the complexity of dealer-level tools. It combines the ten standard OBDII test modes with targeted diagnostics for the four most safety-critical systems (Engine/TCM, ABS, SRS, and Transmission), DTC lookup, data recording/playback and PC printing capability. The unit supports wide vehicle coverage for OBDII functions and system scans on many US, European and Asian models from the early 2000s through mid-2010s, though individual function availability varies by vehicle and year.

How does the ML629 help diagnose a check-engine or ABS/SRS warning?

The ML629 reads stored diagnostic trouble codes (DTCs) from the engine, transmission, ABS and SRS modules and can erase the corresponding warning lights after repair verification. It also includes a built-in DTC library so you can see code definitions on-screen fast, making fault identification quicker.

• Reads and clears codes from Engine/Transmission/ABS/SRS modules.
• Displays DTC definitions from a 10,000+ entry library.
• Saves and plays back recorded data for later review or printing.
• Supports limited system live data (OBDII live data graphs available).

What OBDII and emission checks can it perform before a smog test?

The scanner performs all ten OBDII test modes used for emissions and readiness checks, enabling you to verify I/M readiness monitors and common emission-related systems. That helps determine if the vehicle is likely to pass a smog inspection without guesswork.

• Retrieves I/M Readiness status for catalyst, O2 sensors, EVAP and more.
• Runs O2 monitor and on-board monitor tests, plus freeze-frame and VIN retrieval.
• Graphs live sensor outputs to spot intermittent faults affecting emissions.
• Supports US (post-1996), EU (post-2006), and Asian (post-2009) OBDII coverage.

Can I use AutoVIN, print reports and update the ML629 software?

Yes — AutoVIN helps automatically detect the vehicle identification number when the ECU stores it, which speeds setup. You can save recorded sessions and print them from a Windows PC for documentation, and the device is eligible for free lifetime software updates through Autel.

• AutoVIN for quick vehicle identification (when supported by ECU).
• Data recording, playback and PC printing for diagnostics or service records.
• Lifetime free software updates to keep code libraries and features current.
• Multi-language menus; English preinstalled with options unlockable by support.

Which cars and warranties does the ML629 support?

OBDII functions cover broad model years for US, EU and Asian markets, while the four-system diagnostics support many makes from about 2002–2016/2017. Because coverage and available tests are vehicle-specific, Autel requests VIN or model/year details to confirm compatibility before purchase.

• OBDII coverage: US post-1996, EU post-2006, Asian post-2009 (for emissions tests).
• 4-system diagnostics for 30+ makes, typically 2002–2016/2017 model years.
• 30-day replacement/full refund window and 12-month defect warranty.
• Customer support available for compatibility checks and language unlocks.

Who is this for: The Autel ML629 is tailored for DIYers, home mechanics and small-shop technicians who want a step up from basic code readers. It’s useful when you need targeted ABS/SRS/Engine/Transmission troubleshooting, emissions readiness checks or portable data logging without investing in dealer-level diagnostic hardware. Before ordering, provide your vehicle model, year and VIN to Autel support to confirm the specific functions available for your car.
