1. Understanding the Autel AutoLink AL319 OBDII Scanner
The Autel AutoLink AL319 is an OBDII (On-Board Diagnostics II) scanner designed to read and clear diagnostic trouble codes (DTCs) from your vehicle’s computer. It’s a valuable tool for diagnosing check engine lights, monitoring vehicle health, and performing basic maintenance. This user-friendly device helps you understand your car’s condition and potentially save on expensive mechanic visits.
1.1. What is OBDII and Why is it Important?
OBDII is a standardized system that allows access to diagnostic data from a vehicle’s engine control unit (ECU). It was mandated in the United States for all cars and light trucks manufactured after 1996. OBDII provides valuable information about a vehicle’s emissions system, engine performance, and other critical functions.
Think of OBDII as your car’s built-in health monitor. It constantly checks various systems and components. When it detects an issue, it stores a diagnostic trouble code (DTC) and illuminates the check engine light.

Consult your vehicle’s owner’s manual if you have trouble locating the port. According to the Environmental Protection Agency (EPA), all cars and light trucks manufactured for sale in the United States after January 1, 1996, are required to have a standardized OBDII port.
3. Step-by-Step Guide: Using the Autel AutoLink AL319
Now that you’re familiar with the Autel AutoLink AL319, let’s walk through the steps of using it to diagnose your vehicle.
3.1. Connecting the Autel AutoLink AL319 to Your Vehicle
- Turn off the vehicle’s ignition.
- Locate the OBDII port under the dashboard.
- Plug the Autel AutoLink AL319’s OBDII connector into the port. Ensure it’s securely connected.
3.2. Powering On the Device and Navigating the Menu
The Autel AutoLink AL319 is powered by the vehicle’s OBDII port, so it should power on automatically once connected. If it doesn’t, ensure the connection is secure. Use the scroll buttons to navigate through the main menu options:
- Read Codes: Reads diagnostic trouble codes (DTCs).

- Live Data: Displays real-time sensor data.
- View Freeze Frame: Shows data recorded when a DTC was stored.

3.3. Reading Diagnostic Trouble Codes (DTCs)
- Select “Read Codes” from the main menu.
- The Autel AutoLink AL319 will scan the vehicle’s computer for stored DTCs.
- The DTCs will be displayed on the LCD screen. Note down the codes for further research.
3.4. Understanding and Interpreting DTCs
DTCs are five-character codes that provide information about the specific problem detected by the vehicle’s computer. The first character indicates the system involved:
- P: Powertrain (engine, transmission)
- B: Body (airbags, lighting)
- C: Chassis (ABS, suspension)
- U: Network (communication)
The remaining four characters provide more specific information about the fault. Consult the Autel AutoLink AL319’s built-in DTC library or online resources like CARDIAGTECH.NET to understand the meaning of each code.
3.5. Using the Live Data Feature
The Live Data feature allows you to monitor real-time data from the vehicle’s sensors. This can be helpful for diagnosing intermittent problems or verifying the operation of specific components.
- Select “Live Data” from the main menu.
- Choose the data parameters you want to monitor.
- The Autel AutoLink AL319 will display the real-time values of the selected parameters.
For example, you can monitor engine RPM, coolant temperature, oxygen sensor readings, and fuel trim values.
3.6. Checking I/M Readiness
The I/M Readiness feature checks the status of emissions-related systems. This is useful for determining if your vehicle will pass an emissions test.
- Select “I/M Readiness” from the main menu.
- The Autel AutoLink AL319 will display the status of each system:
- OK: System is ready.
- INC: System is incomplete.
- N/A: System is not applicable.
All systems must be “OK” for your vehicle to pass an emissions test.
3.7. Clearing Diagnostic Trouble Codes (DTCs)
Important Note: Only clear DTCs after you have diagnosed and repaired the underlying problem. Clearing codes without fixing the issue will only result in the check engine light coming back on.
- Select “Erase Codes” from the main menu.
- The Autel AutoLink AL319 will prompt you to confirm that you want to clear the codes.
- Select “Yes” to clear the codes.
- Start the engine and check if the check engine light remains off.

- Select “View Freeze Frame” from the main menu.
- The Autel AutoLink AL319 will display the data recorded when the DTC was stored.
Analyze the Freeze Frame data to identify any unusual readings that may have contributed to the problem.
4.2. Identifying and Resolving Common OBDII Issues
Some common OBDII issues and their potential solutions include:
- P0171/P0174 (System Too Lean): Check for vacuum leaks, faulty MAF sensor, or low fuel pressure.
- P0300 (Random Misfire): Check spark plugs, ignition coils, fuel injectors, and vacuum leaks.
