Already a well-known brand, Autel was founded in 2004 in Shenzhen, China, to manufacture and supply high-quality automotive diagnostic tools, accessories, and equipment. They are committed to providing quality-assured, cost-friendly, and easy-to-use products to their customers.

Let’s take a look into the features of their Autel Autolink AL519 OBDII scanner.


The scan tool comes with the following accessories.

  • USB cable
  • Carrying case
  • Code reader
  • A CD
  • OBD II cable
  • User’s manual


To begin with, this OBDII scanner has a sturdy, robust, and compact design. Measuring only 7.8 x 4.1 x 1.5 inches and weighing just 1.3 pounds with wire, it can be stored anywhere easily, even in the glove box of your car. Along with this, these features make it easy to move from one car to another.

Furthermore, with a comfortable grip, this device fits well in your hands and prevents it from slipping. The included nylon case stores your USB cable safely for later.

Besides that, Autel has included a TFT color display for brighter visuals and ease in scanning the codes in a short period. As a result, the integrated speaker helps to alert the user for readiness and errors by beeping audibly.


Autel Autolink AL519 offers a lot of tasks in a small device. It supports all ten modes and provides a complete, accurate diagnosis of all your vehicle’s problems.

This scan tool offers both the generic, pending, as well as manufacture codes, such as CVN, VIN, and CIN. Moreover, it even allows you to read, erase, and update all the data codes in one device.

Additionally, with a one-click I/M readiness key, you can quickly check the emission readiness and the driving cycle of your OBDII-compatible vehicles by pressing just one button.

Besides this, AL519 detects the cause of the check engine light and stores all the related information for the mechanic to fix the problem. It switches off the light, clears out all the codes, and then resets the monitors for future use. Thus, it even reduces the repairing cost by half.

The OBDII scan tool can even read, playback and store live data for later use. In addition to all this, it shows the DTC definition using the DTC lookup function, checks freeze frame data and displays IM readiness status on the LCD.

If all this was not enough, it even tests and displays O2 sensor data and reads the PCM data stream. Apart from this, its on-board monitor test finds and shows the information on emission-related components.


Since not all the scanning tools in the market will be compatible with the model of your car, it is vital to find one that provides extensive vehicle coverage. Consequently, it ensures that you can use the same device to check all your vehicles.

Fortunately, Autel Autolink AL519 scanner works for all cars introduced after 1996. It is compatible with domestic or imported cars, such as the US, Asian, or European OBDII and CAN vehicles.
