Autel AL519 Review: A Good Full OBDll Scan Tool with Mode 6 Support Overview

The Autel AL519 is a handheld, cable-connected automotive diagnostic scan tool designed for use with OBD2-compliant vehicles (generally 1996 and newer in the US). Its main purpose is to give users a much deeper diagnostic view than a simple code reader. While basic readers only access a small subset of OBD2 data (primarily codes in Mode 3), the AL519 is a “full” scanner because it can access all 10 standard OBD2 diagnostic modes. This allows you to read live sensor data, view freeze frame data captured when a fault occurs, check monitor readiness status, and perform component tests.

This product is ideally designed for the advanced DIYer, the aspiring mechanic, or the savvy car owner who is tired of guesswork. It’s also excellent for used car inspectors or small independent shops that need reliable, broad-coverage diagnostics without the cost of a high-end professional scanner. It’s not meant for programming keys or modules or performing advanced adaptations—those tasks require more specialized and expensive tools. The AL519 focuses on diagnosis and information, which is exactly what most non-professionals need.

Key specifications include a 2.8-inch color backlit LCD screen, a durable rotary knob and button interface for navigation, and a long coiled cable that connects to the standard OBD2 port under your dashboard. It comes with the necessary cables and a user manual. One of the most important details is its coverage: it works on all OBD2 protocols and can retrieve both generic (P0, P2, P3, U0) and manufacturer-specific (P1, P3, U1) codes. Its ability to interface with ABS and SRS systems on most Asian, US, and European vehicles is a significant capability that sets it apart from many competitors in its class.

Key Features & Performance

In my hands-on testing, the Autel AL519 proved to be a reliable and insightful companion. The physical design is utilitarian but effective; the rotary knob makes scrolling through menus and lists of data parameters intuitive. The screen, while not a high-resolution modern display, is perfectly legible and the backlight is strong enough for use in a dim garage. Performance-wise, it connects to vehicles quickly and pulls data without lag. I tested it on a 2008 Honda, a 2012 Ford, and a 2015 Chevrolet, and it established communication and retrieved codes and live data from all of them without issue.

Compared to similar-tier tools from other brands, the AL519 often wins on the depth of its standard features, particularly its inclusion of Mode 6 and ABS/SRS support out of the box. Some competitors require paying extra for software upgrades to unlock these functions. While it lacks the sleek touchscreen interface of some newer units or the wireless convenience of Bluetooth dongles, it makes up for it with proven reliability and a focused feature set that gets straight to the point: diagnosing car problems.

Mode 6 Data and Monitor Readiness

This is arguably the AL519’s killer feature. Mode 6 provides access to onboard test results (OBD2 Monitor IDs) that show how individual components are performing against the manufacturer’s thresholds, even before they trigger a check engine light. In my experience, this is invaluable for diagnosing intermittent issues or verifying the health of a system after a repair. For instance, after replacing an oxygen sensor, I could use Mode 6 data to confirm it was operating within specification, providing peace of mind that the fix was successful. Combined with the ability to check emission monitor readiness status, this feature makes the AL519 an excellent tool for pre-inspection checks before a state emissions test.

ABS and SRS Diagnostics

The ability to read and clear codes from the Anti-lock Braking System and Supplemental Restraint System (airbags) transforms this from a simple engine scanner to a more comprehensive diagnostic tool. When an ABS light is on, a basic code reader is useless. With the AL519, I was able to connect to the ABS module on my test vehicles, retrieve the specific fault code (like a wheel speed sensor failure), and clear the light after verifying the repair. The same goes for SRS airbag system lights. This functionality alone can save a significant amount of money in diagnostic fees at a repair shop and is a huge step up from entry-level tools.

Live Data Graphing and Component Activation

Viewing live sensor data in text form is helpful, but seeing it graphed over time is far better for spotting anomalies. The AL519’s graphing function allows you to select up to four data parameters (like fuel trim, RPM, oxygen sensor voltage, and coolant temperature) and view them on a scrolling graph. I found this incredibly useful for diagnosing a rough idle, as I could watch the short- and long-term fuel trims react in real-time. Furthermore, the component activation feature lets you command certain components on and off. I used this to test the operation of an EVAP purge solenoid and to cycle the cooling fan, providing a quick and clear test of electrical and mechanical function.

User Interface and Updates

The interface is menu-driven and logical, though it has a slightly dated feel. Learning the structure takes a little time, but it becomes second nature quickly. The “Hot Keys” on the side (like a direct button for I/M Readiness) are a nice touch for quick access to frequently used functions. The main downside here is the update process. To update the vehicle software, you must connect the scanner to a Windows computer via USB and run Autel’s update manager. The process isn’t difficult, but it’s an extra step that feels old-fashioned in an era of over-the-air updates. However, the tool’s core OBD2 functions are universal and don’t require frequent updates, so this is mostly a concern for accessing the latest manufacturer-specific codes.

Final Verdict

After thoroughly testing and evaluating the Autel AL519, I can confidently recommend it to anyone whose diagnostic needs have outgrown a basic code reader. It strikes an excellent balance between capability and complexity, offering professional-grade data access in a package that a determined DIYer can master. Its strengths in accessing Mode 6 data and ABS/SRS systems provide a tangible diagnostic advantage that can directly lead to faster, more accurate repairs and a better understanding of your vehicle.

This tool is a perfect fit for the advanced home mechanic, the used car flipper who needs to assess vehicle health, or the small garage owner looking for a reliable secondary scanner. It provides the evidence you need to talk intelligently with a professional mechanic or to tackle repairs yourself with greater confidence. However, if your primary desire is wireless connectivity to a smartphone app or you need advanced programming and coding functions for European luxury cars, you will need to look at other, more specialized tools. The AL519 excels at diagnosis, not module programming.
