Why Choose the Autel AL519?
- Affordable yet feature-rich: Provides more diagnostic functions than many basic code readers.
- User-friendly interface: Simple plug-and-play operation makes it suitable for beginners.
- Wide vehicle compatibility: Works with most 1996 and newer US-market OBD2-compliant vehicles and many compatible international models.
- Reliable engine diagnostics: Reads and clears trouble codes, displays freeze-frame data, and checks I/M readiness status.
- Additional features: Supports O2 sensor tests, component tests, and on-board monitoring where available.
- Data recording: Allows users to save and review diagnostic information.
- Electrical testing: Includes an AVOmeter function and basic 12V battery, starting, and charging system checks.
Need more advanced diagnostics? Consider the Autel AL619 ABS/SRS scanner or the Autel MaxiDiag MD802 if you need additional vehicle system coverage.
1. Does the Autel AL519 scanner show which cylinder is misfiring?
Yes, when the vehicle stores a cylinder-specific misfire code. For example, P0301 indicates a misfire detected in cylinder 1, while P0302 refers to cylinder 2. However, P0300 indicates random or multiple-cylinder misfires and does not identify one specific cylinder.
2. Can it check the engine temperature?
Yes. The AL519 can display available live data such as engine coolant temperature, RPM, fuel trims, and oxygen sensor information. The exact readings depend on what your vehicle supports.
3. Is the Autel AL519 compatible with iOS devices?
No. The AL519 is a standalone wired scanner and does not connect directly to iPhones or iPads. If you prefer a smartphone-based scanner, consider the Autel AP200 or another compatible Bluetooth diagnostic device.
4. Does the Autel AL519 support Battery Management System (BMS) services?
No. Although it can perform basic battery and charging system checks, it cannot register or program a replacement battery in a vehicle’s Battery Management System.
5. Can the Autel AL519 read airbag (SRS) data?
No. It focuses on standard OBD2 engine and emissions diagnostics. It does not provide dedicated SRS airbag or ABS system diagnostics.

Autel AL519 vs AL319: What Are the Key Differences?
The Autel AL519 offers several functions beyond the basic capabilities of the AL319, including:
- O2 Monitor Test: Retrieves available oxygen sensor monitoring results to help diagnose emissions-related problems.
- Battery and Electrical Testing: Supports basic 12V electrical system checks, including starting and charging system diagnostics.
- Save and Playback Data: Allows users to record diagnostic information and review it later.

- Print Data via PC: Supports saving and printing diagnostic reports using compatible computer software.
- On-Board Monitor Test: Retrieves available results from vehicle self-diagnostic monitors.
- Component Test: Requests supported component activation tests through the OBD2 system.
Looking for a simple code reader? The AL319 is a practical alternative for checking engine codes and emissions readiness. However, if you want additional diagnostic functions and recorded data, the AL519 offers more flexibility.
The Autel AL519 features a TFT color screen, built-in speaker, and clearly labeled buttons. It supports all 10 standard OBD2 test modes and can read generic, pending, and supported manufacturer-specific diagnostic trouble codes.
However, individual test functions depend on your vehicle’s capabilities. Supporting all 10 OBD2 modes does not mean the scanner can access every electronic control module.

Fault Code Reader Autel AL519 Review 2026
If you’re looking for a budget-friendly, easy-to-use, and feature-rich OBD2 scanner, the Autel AL519 remains a capable option for standard engine diagnostics.
It goes beyond basic code reading by offering on-board monitoring, O2 sensor tests, live data recording, and freeze-frame analysis. These functions make it useful for DIY mechanics who want to investigate problems before visiting a repair shop.
However, because the AL519 is an older model, you should compare its price and availability with newer scanners before purchasing.
Autel AL519 Vehicle Compatibility: Extensive Coverage
One important feature of any scan tool is vehicle coverage. Before buying, check whether the scanner supports your vehicle’s make, model, and diagnostic protocol.
The Autel AL519 works with most 1996 and newer OBD2-compliant vehicles sold in the United States. It also supports many European and Asian vehicles equipped with compatible OBD2 or EOBD systems.
Supported protocols include CAN, ISO9141, KWP2000, J1850 PWM, and J1850 VPW.
However, not every vehicle manufactured after 1996 is compatible. Some international markets adopted OBD2 requirements later, and certain functions may not be available on every vehicle.

Interface: Easy to Use
Whether you’re a beginner or a DIY mechanic, operating this code reader should not be difficult. The AL519 features an intuitive interface with clearly labeled navigation buttons.
Its TFT color screen makes diagnostic codes and live data easy to read, even in a dimly lit garage.
The built-in speaker provides audible alerts for readiness checks, while the color-coded LEDs help you quickly understand emissions monitor status.
Multilingual Support
The multilingual menu makes the AL519 easier to use for people who prefer languages other than English.
Autel provides different language packages, including combinations of English, French, German, Spanish, Dutch, and other supported languages.
Language availability depends on the installed software package. Contact Autel support if you need help selecting the correct version.

Display: TFT Color Screen
The Autel AL519 comes with a 320 x 240 TFT color display and built-in speaker. These features make it easier to view fault codes, live sensor readings, and diagnostic menus.
Its color-coded LEDs provide quick visual feedback during emissions readiness checks. The speaker also produces audible signals, so you don’t always need to look closely at the display to recognize the readiness result.
Performs Several Diagnostic Functions
Despite its affordable positioning, the AL519 provides a useful range of diagnostic features.
It can retrieve generic, manufacturer-specific, and pending OBD2 codes, view freeze-frame information, check I/M readiness, and record live engine data.
The scanner can also clear stored codes and turn off the check engine light after the underlying problem has been repaired.
However, clearing diagnostic codes does not repair the fault. It also resets relevant readiness monitors, which may need additional driving before an emissions inspection.
The built-in troubleshooting information helps users understand common problems, although further testing is often necessary to identify the exact cause.

Internet Updateable
The Autel AL519 supports software updates through a computer and USB connection. This allows users to install available firmware and DTC library updates.
Autel has provided downloadable update packages for this model. However, since the AL519 is now classified as a legacy product, ongoing support for new vehicle features should not be assumed.
Before purchasing, check whether the available update software works with your computer.
One-Year Warranty
The AL519 has been sold with a one-year manufacturer warranty. This provides some protection against qualifying manufacturing defects.
However, warranty eligibility may depend on the seller, purchase date, region, and whether the scanner is new or previously owned. Check the current warranty terms before buying, particularly because this is a discontinued model.
