Check for any physical damage. If anything is missing or damaged, contact CARDIAGTECH.NET for assistance.
2.2. Powering On and Navigating the Device
The Autel AutoLink AL319 is powered directly through the OBDII port of your vehicle. To power it on:
- Locate the OBDII port in your vehicle. It’s usually under the dashboard on the driver’s side.
- Plug the Autel AutoLink AL319 into the OBDII port.
- The device will power on automatically.
Use the navigation buttons to scroll through the menu options. The intuitive interface makes it easy to find the functions you need.
2.3. Updating the Software
Keeping your Autel AutoLink AL319 software up to date is essential for accessing the latest features and ensuring compatibility with newer vehicles.
- Visit the Autel website (CARDIAGTECH.NET) and download the update software to your computer.
- Connect the Autel AutoLink AL319 to your computer using the provided USB cable.
- Run the update software and follow the on-screen instructions.
- Ensure the device remains connected until the update is complete.
3. Reading and Interpreting Autel AutoLink AL319 Codes
Once your Autel AutoLink AL319 is set up, you can begin reading and interpreting diagnostic trouble codes. This section will guide you through the process.
3.1. Connecting to Your Vehicle’s OBDII Port
- Turn off your vehicle’s engine.
- Locate the OBDII port (usually under the dashboard on the driver’s side).
- Plug the Autel AutoLink AL319 into the OBDII port.
- Turn the ignition to the “ON” position, but do not start the engine.
- The Autel AutoLink AL319 will power on and begin communicating with your vehicle’s computer.
3.2. Retrieving Diagnostic Trouble Codes (DTCs)
- From the main menu, select “Read Codes.”
- The Autel AutoLink AL319 will scan your vehicle’s computer and display any stored DTCs.
- DTCs are typically displayed as a five-character code (e.g., P0300).
3.3. Understanding Different Types of Codes
DTCs are categorized into several types:
- P Codes (Powertrain): Relate to the engine, transmission, and associated components.
- B Codes (Body): Relate to body systems, such as airbags, power windows, and locks.
- C Codes (Chassis): Relate to chassis systems, such as ABS (Anti-lock Braking System) and traction control.
- U Codes (Network): Relate to the vehicle’s communication network.
The first digit of the code indicates the category:
- 0: Generic (standardized across all manufacturers)
- 1: Manufacturer-specific
For example, a P0 code is a generic powertrain code, while a P1 code is a manufacturer-specific powertrain code.
3.4. Using the Autel AutoLink AL319 to Define Codes
The Autel AutoLink AL319 has a built-in DTC library that provides definitions for most codes.
- After retrieving the codes, select a code from the list.
- The device will display the code definition, providing a brief description of the problem.
- For more detailed information, refer to your vehicle’s repair manual or online resources.
For instance, if you retrieve a P0300 code, the Autel AutoLink AL319 will define it as “Random Misfire Detected.” This indicates that the engine is misfiring, but the specific cylinder causing the misfire has not been identified.
3.5. Interpreting Freeze Frame Data
Freeze frame data captures a snapshot of the vehicle’s operating conditions when a DTC was stored. This data can help you diagnose the problem by providing information such as:
- Engine RPM
- Vehicle speed
- Engine load
- Coolant temperature
- Fuel trim
To view freeze frame data:
- From the main menu, select “Freeze Frame.”
- The Autel AutoLink AL319 will display the stored data.
Analyzing freeze frame data can provide valuable clues about the cause of the problem. For example, if the engine load was high when the misfire occurred, it may indicate a problem with the fuel system or ignition system.
4. Common Autel AutoLink AL319 Codes and Their Meanings
Understanding common DTCs can help you quickly identify and address common issues. Here’s a list of some of the most frequently encountered codes and their potential meanings:
4.1. P0300 – Random Misfire Detected
Description: This code indicates that the engine is experiencing random misfires. A misfire occurs when one or more cylinders do not fire correctly, resulting in incomplete combustion.
Possible Causes:
- Faulty spark plugs
- Faulty ignition coils
- Vacuum leaks
- Clogged fuel injectors
- Low fuel pressure
- Faulty oxygen sensor
- Faulty mass airflow (MAF) sensor
- Faulty crankshaft position sensor
- Faulty camshaft position sensor
4.2. P0171 – System Too Lean (Bank 1)
Description: This code indicates that the engine is running too lean, meaning there is too much air and not enough fuel in the air-fuel mixture. Bank 1 refers to the side of the engine that contains cylinder #1.
Possible Causes:
- Vacuum leaks
- Faulty oxygen sensor
- Low fuel pressure
- Clogged fuel injectors
- Faulty mass airflow (MAF) sensor

- Engine misfires
4.4. P0401 – Insufficient EGR Flow
Description: This code indicates that there is not enough exhaust gas recirculating through the EGR (Exhaust Gas Recirculation) system. The EGR system helps reduce NOx (nitrogen oxides) emissions.
Possible Causes:
- Clogged EGR valve
- Faulty EGR valve
- Vacuum leaks
- Faulty EGR pressure sensor
4.5. P0113 – Intake Air Temperature Sensor Circuit High Input
Description: This code indicates that the intake air temperature (IAT) sensor is reporting an abnormally high temperature.
Possible Causes:

Possible Causes:
- Faulty wheel speed sensor
- Damaged or corroded wiring
- Issues with the ABS control module
5. Clearing Codes with the Autel AutoLink AL319
After addressing the underlying issue, you can use the Autel AutoLink AL319 to clear the DTCs and turn off the check engine light.
5.1. When to Clear Codes
It’s important to clear codes only after you have diagnosed and repaired the underlying problem. Clearing codes without fixing the issue will only temporarily turn off the check engine light, and the code will likely return.
5.2. Step-by-Step Instructions for Clearing Codes
- Ensure the Autel AutoLink AL319 is connected to your vehicle’s OBDII port.
- Turn the ignition to the “ON” position, but do not start the engine.
- From the main menu, select “Erase Codes.”
- The device will display a warning message. Read it carefully and confirm that you want to proceed.
- Select “Yes” to clear the codes.
- The Autel AutoLink AL319 will clear the codes and reset the monitors.
- Turn off the ignition and then start the engine to verify that the check engine light remains off.
5.3. Understanding Monitor Status
After clearing the codes, the Autel AutoLink AL319 will display the monitor status. Monitors are diagnostic tests that the vehicle’s computer performs to ensure that various systems are functioning correctly.
Common monitors include:
- Misfire Monitor
- Fuel System Monitor
- Comprehensive Component Monitor
- Catalyst Monitor
- Oxygen Sensor Monitor
- EGR System Monitor
If a monitor is “Not Ready,” it means that the test has not yet been completed. It may take several drive cycles for all monitors to become “Ready.” A drive cycle consists of a series of driving conditions that allow the vehicle to perform the necessary tests.
