Autel AL329 OBDII Code Reader (Upgraded AL319) — Live Data & I/M Readiness

The Autel Autolink AL329 (upgraded AL319) is a handheld OBDII code reader that quickly reads and clears engine trouble codes, displays live vehicle data and checks emissions readiness on 1996-and-newer OBDII/EOBD cars.

The AL329 is a compact, user-friendly diagnostic tool from Autel designed for DIYers and technicians who need fast access to engine fault codes and live sensor data. It connects to the vehicle's OBDII port, retrieves generic and manufacturer-specific DTCs, shows VIN and calibration info, and helps identify whether the malfunction indicator light (MIL) is active or if emission monitors are ready. The unit’s tri-lingual interface, durable build and color TFT screen make trouble-shooting straightforward without a subscription.

How does the AL329 identify problems and what code types does it read?

The AL329 reads both generic (P0, P2, P3, U0) and many manufacturer-specific (P1, P3, U1) trouble codes, including pending faults. It also retrieves vehicle identification information like VIN, CALID and CVN to help match fixes to the correct software and parts.

• Retrieves generic and manufacturer-specific DTCs
• Shows pending codes and freeze frame data for context
• Displays VIN, calibration ID and CVN for vehicle verification

Can the scanner clear codes and help with emissions readiness?

Yes—Autel's one-click I/M readiness function checks active monitors and tells you if emission tests are likely to pass. After repairs, the AL329 can clear stored codes, reset monitors and turn off the MIL when issues are resolved.

• One-press I/M readiness check for emissions testing
• Clear codes and reset monitors to extinguish MIL
• View freeze frame snapshots to see fault conditions

What live data and advanced functions are included?

The device graphs and records live sensor streams so you can observe values over time, then playback for review. It also supports Enhanced Mode 6 diagnostics to access deeper test results available from many ECUs, helping narrow down intermittent or complex failures.

• Live data streaming with graph, record and playback
• Enhanced Mode 6 for advanced diagnostic information
• TFT color display improves readability of data and graphs

Is the AL329 easy to use and which vehicles are supported?

The AL329 is plug-and-play: connect the OBDII cable and the unit powers up from the vehicle for immediate scanning. It supports most domestic, Asian and European models from 1996 onward that comply with OBDII/EOBD standards, and offers menus in English, Spanish and French.

• Compatible with 1996+ OBDII/EOBD domestic, Asian and European vehicles
• Plug-in operation—vehicle-powered, no batteries needed
• Tri-lingual interface and splash-resistant housing for durability

Who this is for: The Autel Autolink AL329 suits car owners, mobile mechanics and small-shop technicians who want an affordable, reliable scanner to diagnose engine issues, monitor emissions readiness and record live data without subscription fees. If you need a rugged, easy-to-use code reader that supports both basic repairs and more in-depth troubleshooting, the AL329 delivers essential diagnostic functions in a handheld package.
