Getting Started with Your Autel AutoLink AL319
Before you begin, ensure your vehicle is parked on a level surface, the engine is off, and the parking brake is engaged.

Locate Your Vehicle’s OBD2 Port: The OBD2 port is typically located under the dashboard on the driver’s side. Look for a 16-pin trapezoidal connector.
-
Connect the Scanner: Insert the Autel AL319’s connector into the OBD2 port. You should hear a click when it’s securely connected.
-
Turn On the Ignition: Turn the key to the “on” position, but don’t start the engine. This powers up the scanner and allows it to communicate with your car’s computer.
-
Turn on the Scanner: The Autel AL319 should turn on automatically when it establishes a connection with your vehicle’s computer.
-
Select Your Vehicle Information: You might be prompted to input information about your vehicle, such as the year, make, and model. This helps the scanner to tailor its diagnostic capabilities for your specific car.

Navigate the Menu: The Autel AL319 has a user-friendly interface. Use the buttons on the device to navigate through the menus and select the functions you need.
Reading and Understanding Diagnostic Trouble Codes
Autel AL319 Reading Diagnostic Codes
One of the primary uses of the Autel AutoLink AL319 is to read and understand Diagnostic Trouble Codes (DTCs). DTCs are codes stored in your car’s computer that indicate a specific problem area.
To read codes, select the “Read Codes” option from the main menu. The Autel AL319 will then scan your vehicle’s computer for any stored codes. Once the scan is complete, the codes will be displayed on the screen.
Each DTC consists of a five-digit alphanumeric code. The first character indicates the system where the fault is detected (e.g., “P” for powertrain, “B” for body, “C” for chassis, “U” for network communication). The remaining four characters specify the particular issue.
For example, a code “P0301” indicates a misfire detected in cylinder 1.
The Autel AL319 not only displays the codes but also provides a brief description of what each code means. This can be incredibly helpful in understanding the nature of the problem.

Beyond reading and clearing codes, the Autel AL319 offers several other helpful functions:
- Live Data Stream: This feature allows you to view real-time data from your car’s sensors, such as engine RPM, coolant temperature, oxygen sensor readings, and more.
