Autel Autolink AL329 OBDII Code Reader - Upgraded AL319, Color TFT, Live Data & I/M Readiness

The Autel Autolink AL329 (upgraded AL319) is a compact OBDII code reader that reads and clears engine fault codes, checks emissions readiness, and displays live sensor data for 1996-and-newer vehicles.

Designed for DIY mechanics, fleet techs, and automotive enthusiasts, the Autel AL329 gives quick access to vehicle trouble codes and live data without complex menus or subscriptions. It supports domestic, Asian and European cars built since 1996 that follow OBD II/EOBD standards, and offers a color TFT screen for clear code and graph displays. The unit’s water- and grease-resistant housing plus tri-lingual interface (English, Spanish, French) make it practical in garage or roadside conditions.

How does the AL329 identify and present diagnostic trouble codes?

The AL329 retrieves generic (P0, P2, P3, U0) and manufacturer-specific (P1, P3, U1) trouble codes plus pending codes, then shows descriptions and freeze-frame data to help you pinpoint issues. Vehicle identification (VIN, CALID, CVN) is accessible where supported, so you can confirm compatibility and firmware details.

• Reads and displays generic, manufacturer-specific and pending DTCs
• Shows freeze-frame snapshot of sensor values at fault occurrence
• Retrieves VIN, CALID and CVN for accurate vehicle identification
• Simple code explanations on the TFT color display

Can I clear codes and reset readiness monitors with this scanner?

Yes — the AL329 clears diagnostic trouble codes and can reset monitors to switch off the malfunction indicator light (MIL) after repairs. It also includes a one-button I/M readiness check to quickly confirm which emission monitors are complete or incomplete.

• Clear codes to turn off MIL after troubleshooting
• One-click I/M emissions readiness test for state inspections
• Resets monitors so you can verify completed repairs
• Records basic history with viewable freeze-frame data

What live data and advanced features does it offer?

The AL329 streams live sensor values and supports graphing, recording and playback so you can watch parameters change in real time. Enhanced Mode 6 diagnostics are included for deeper insight into emission-related tests when supported by the vehicle.

• Streams live data for sensors like RPM, speed, fuel trim and more
• Graph, record and playback data to compare before/after repairs
• Includes Enhanced Mode 6 diagnostic data where available
• TFT color screen (220x176 DPI) presents readable graphs and lists
