The Autel AutoLink AL319 OBD2 scanner is marketed as an entry-level tool for diagnosing car issues related to the check engine light. As someone who regularly works on cars and owns several diagnostic scanners, I was interested to see how this compact and budget-friendly device performs. This review provides an in-depth look at the Autel AL319, examining its features, usability, and overall value for money.
At first glance, the AL319 is remarkably simple. Its small size is immediately noticeable, especially when compared to older, bulkier scanners. The device features a basic interface with just three buttons – two for scrolling and one “ENTER/Exit” button. Connecting it to a vehicle and reading diagnostic trouble codes (DTCs) is straightforward, even without consulting the manual. The AL319 is also capable of erasing codes and checking for pending codes, covering the fundamental functions expected from an OBD2 scanner at this price point.
However, the simplicity of the user interface also presents a minor drawback. Navigating the menus isn’t immediately intuitive. Unlike scanners with dedicated exit buttons, the AL319 requires using the scroll button to find a “return” or “previous menu” option. While this is a minor inconvenience and quickly learned, it initially caused some confusion. Another area for potential improvement is the cable length. The integrated 2-foot cable is shorter than ideal. A longer cable offers greater flexibility, particularly when working on a lifted vehicle or wanting to view live data while driving or having a passenger monitor it. For basic code reading in a parked car, the cable length is sufficient, but it might be restrictive in more dynamic diagnostic scenarios. These two points, the user interface navigation and cable length, are the primary limitations I encountered during my testing.
Despite these minor drawbacks, the Autel AL319 excels in several key areas, significantly outweighing its limitations. Here’s a breakdown of its strengths:
- Rapid Boot-up: The AL319 starts up incredibly quickly, allowing for near-instant diagnostics. This is a notable advantage when you need to quickly check a code.
- Bright Color Display: The inclusion of a color screen is a welcome feature at this price point. The display is bright and clear, making it easy to read codes and data, even in varying lighting conditions.
- Dedicated I/M Readiness Key: A standout feature is the dedicated “I/M Readiness” button. With a single press, you can quickly determine if your vehicle is ready for an emissions test. The scanner uses a color-coded LED system (Green, Yellow, Red) to indicate emissions readiness status, simplifying the process of checking if all necessary monitors have run.
- Manufacturer-Specific Codes: Beyond standard OBD2 codes, the AL319 can detect some manufacturer-specific codes. When it identifies such a code, it prompts you to select the vehicle’s make and model. While it’s important to note that the AL319 primarily focuses on engine-related codes and does not access systems like Transmission, ABS, or Airbag modules, its ability to read some manufacturer-specific engine codes is a valuable addition at this level.
- Live Data Stream: The AL319 supports live OBD2 data streaming. This feature allows you to monitor real-time engine parameters such as coolant temperature, oxygen sensor readings, and more. The refresh rate of the live data is impressively fast and smooth, making this function genuinely useful for in-depth troubleshooting, beyond simply replacing parts based solely on error codes. This responsive live data display is a significant advantage over some other budget scanners.
- Responsive and Fast Navigation: Once you become accustomed to the menu navigation, the device is very responsive. Menu transitions are quick, and code retrieval is fast, contributing to an efficient diagnostic process.
- Broad Vehicle Compatibility: I tested the AL319 on a wide range of vehicles from different manufacturers including Honda, Toyota, Subaru, VW, and Nissan, and encountered no compatibility issues reading engine codes. As long as your vehicle is OBD2 compliant (most cars manufactured after 1996 in the US are), the Autel AL319 should work effectively.
Conclusion:
The Autel AL319 OBD2 scanner proves to be a highly capable and portable code reader, especially considering its price point. While the user interface navigation could be more intuitive initially, and the cable length is somewhat short, these are minor issues that are easily outweighed by its strengths. The fast boot-up, bright screen, dedicated emission readiness button, manufacturer-specific code capability, and responsive live data make the AL319 a valuable tool for DIY car owners and anyone needing a basic, reliable OBD2 scanner. It’s an excellent choice for keeping in your car for on-the-go diagnostics and is a tool I would confidently recommend as a primary, portable code reader. For users seeking a budget-friendly, user-friendly, and feature-rich OBD2 scanner, the Autel AL319 is definitely worth considering.
