The Autel Al319 Obd2 Scanner is a popular entry-level tool designed for car owners and DIY enthusiasts to quickly diagnose check engine lights and perform basic vehicle health checks. As someone with experience using various OBD2 scanners, I recently had the opportunity to test the Autel AL319 and evaluate its performance. Here’s an in-depth look at my experience with this compact and user-friendly device.
One of the first things you notice about the AL319 is its size. Compared to older, bulkier scanners, the Autel AL319 is remarkably small and portable. Its straightforward design features just three buttons, simplifying navigation. Connecting the scanner to my vehicle and reading diagnostic trouble codes was intuitive, even without consulting the manual initially. The device effectively scans the car’s computer, reads trouble codes that trigger the check engine light, and provides the ability to clear these codes. It also checks for pending codes, offering a more complete picture of your vehicle’s health.
Key Features and Benefits of the Autel AL319
Despite its simplicity, the Autel AL319 packs a range of useful features that make it a valuable tool for basic vehicle diagnostics:
Fast Boot-up and Bright Color Display
The AL319 boots up almost instantly, saving you time when you need to quickly check your vehicle. The bright color screen is a significant advantage, making it easy to read codes and data, even in varying lighting conditions. This is a notable improvement over older scanners with monochrome displays.
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 emissions testing. The scanner uses a color-coded LED system: a green light indicates readiness, yellow suggests some monitors are not ready, and red signals a problem. This feature can save you a trip to the testing station and potential re-test fees.
Reads Generic and Manufacturer-Specific Codes
The Autel AL319 is capable of reading both generic OBD2 codes and some manufacturer-specific codes. When a manufacturer-specific code is detected, the device prompts you to select the vehicle make and model. While it primarily focuses on engine-related codes, this enhanced capability can provide more detailed diagnostic information compared to basic scanners that only read generic codes. It’s important to note that this scanner is designed to read engine fault codes and does not access systems like Transmission, ABS, or Airbag modules, which is typical for scanners in this price range.
Live Data Stream
The ability to read live OBD2 data is a surprisingly robust feature of the AL319. This function allows you to monitor real-time engine parameters such as coolant temperature and oxygen sensor readings. The refresh rate of the live data screens is impressively fast and smooth, making it genuinely useful for troubleshooting beyond just reading error codes. Observing live data can be invaluable in pinpointing intermittent issues or understanding how different engine components are performing under various conditions.
Responsive and User-Friendly Navigation
Overall, the menu navigation is quick and responsive. Despite the initial minor learning curve with the button layout, once you become familiar with using the scroll button for menu navigation, the device is easy to operate. The system is logically structured, allowing for efficient access to different functions.
Broad Vehicle Compatibility
I tested the AL319 on a variety of vehicle makes, including Honda, Toyota, Subaru, VW, and Nissan, without any compatibility issues. As long as your vehicle is OBD2 compliant (most vehicles manufactured after 1996 in the US are), the Autel AL319 should be compatible and function as expected for reading engine codes.
Minor Considerations
While the Autel AL319 offers significant value and functionality, there are a couple of minor drawbacks to consider:
Navigation Learning Curve
The user interface, while simple, does have a slight learning curve, particularly regarding menu navigation. The “ENTER/Exit” button’s function is not immediately intuitive for exiting menus, requiring the use of the scroll button to find the “return” option. However, this is quickly overcome with a little use and is a minor issue overall.
Cable Length
The attached cable is approximately 2 feet long, which might be shorter than some users are accustomed to. While sufficient for most basic scanning when the car is parked, a longer cable could be beneficial in situations where you need to position the scanner outside the vehicle or observe live data while driving (with a passenger assisting). For typical DIY use in a garage or driveway, the cable length is generally adequate.
Conclusion: A Highly Recommended Portable OBD2 Scanner
In summary, the Autel AL319 OBD2 Scanner is an excellent, portable tool that provides a great balance of features and ease of use for its price point. Its fast boot-up, bright display, dedicated I/M readiness button, live data capabilities, and broad vehicle compatibility make it a standout choice for car owners and DIY mechanics. While there are minor points like the initial navigation learning and cable length, these are easily outweighed by the scanner’s numerous advantages.
For anyone looking for a reliable, entry-level OBD2 scanner to keep in their car for diagnosing check engine lights and monitoring vehicle health, the Autel AL319 is a highly recommended option. Its portability and comprehensive features make it a valuable tool for everyday vehicle maintenance and diagnostics.
