Autel AL329 OBDII Code Reader (Upgraded AL319) — Plug-and-Play, Live Data & I/M Readiness

The Autel Autolink AL329 (upgraded AL319) is a plug-and-play OBDII code reader that reads and clears engine fault codes, checks emissions readiness, and shows live vehicle data.

Designed for technicians, DIYers and fleet operators, this compact Autel scanner connects directly to the OBDII port on 1996-and-newer domestic, Asian and European vehicles. It provides fast diagnostic information—generic and manufacturer-specific codes, VIN and monitor status—on a bright color TFT screen. The AL329 balances essential functionality with an intuitive interface so you can identify issues quickly and make informed service decisions.

How will this scanner help me find engine trouble?

The AL329 retrieves stored, pending and manufacturer-specific trouble codes so you can pinpoint why the check engine light is on. It displays freeze-frame data and live sensor readings to give context to faults.

• Shows freeze-frame snapshots for fault conditions
• Displays enhanced Mode 6 diagnostics for deeper insights

Can it reset codes and check emissions readiness?

Yes — the device clears diagnostic trouble codes and resets monitors, helping you turn off the malfunction indicator lamp after repairs. The one‑touch I/M Readiness key quickly reports monitor status for emissions testing.

• Clear codes and reset monitor readiness
• One-click I/M emission readiness check
• Displays VIN, CAL ID and CVN to confirm vehicle identity

What live data and display features does the AL329 offer?
