Autel AutoLINK AL629

Autel AutoLINK AL629 4-System OBD II Code Reader

The AutoLINK AL629 is Autel's 4-system light-duty code reader — covering engine, ABS, SRS (airbag), and transmission on domestic, Asian, and European vehicles 1996 and newer. It reads and erases codes across all four systems, displays and graphs live data, and supports all 10 OBD II test modes. For a shop that handles passenger cars and light trucks and wants a reliable, affordable tool to address the full range of check-engine, ABS, airbag, and transmission warning lights, the AL629 is a solid daily driver.

Who This Tool Is For

The AL629 is a good match for:

• Independent repair shops doing general diagnostics on passenger cars and light trucks — the 4-system coverage hits the most common fault lights customers bring in
• Technicians who want airbag and transmission code capability without spending $300+ on a scan tool
• Shops that need a reliable backup code reader with broader system coverage than a basic engine-only tool

The AL629 does not do active tests or bi-directional commands, and it does not cover manufacturer-specific service resets (oil reset, TPMS, etc.). Those functions require stepping up to a full scan tool like the Autel MaxiCheck or MaxiSYS series. But for reading and clearing codes and pulling live data across all four major systems, it covers the job.

4-System Coverage

• Engine (PCM) — full OBDII diagnostics, all 10 test modes, enhanced Mode 6
• ABS — anti-lock brake system fault codes and live data
• SRS / Airbag — supplemental restraint system codes
• Transmission — transmission control module fault codes

All four systems can be read and cleared. The AL629 also retrieves vehicle information: VIN, CALID, and CVN.

Live Data and Diagnostics

• Graph, record, and play back live data — visualize sensor readings over time; capture and replay data for intermittent fault diagnosis
• Freeze Frame data — see the exact conditions when a fault code was set
• O2 Monitor and On-Board Monitor tests — verify sensor function and emissions readiness
• I/M Readiness / Emissions status — quick pass/fail for emissions testing
• Enhanced Mode 6 diagnostics — deeper access to OBDII monitor test results
• Component Test — test emission-related components
• AutoVIN 2006+ — automatic vehicle identification with manufacturer-specific code support

AL629 vs. the AutoLINK Lineup

The AL629 sits at the top of Autel's basic AutoLINK code reader line. The AL529HD handles heavy-duty commercial vehicles. The AL549 adds battery testing but only covers Engine + ABS. The AL629 covers all four light-duty systems. For anything beyond reading and clearing codes — service resets, active tests, bi-directional controls — you would need to move into the MaxiCheck or MaxiSYS product lines.
