Autel AL319 OBD2 Scanner User Manual

1. Introduction

The Autel AutoLink AL319 is a compact, user-friendly OBDII/EOBD scanner designed to quickly and efficiently diagnose issues with your vehicle's engine system. It supports all OBDII protocols, including CAN, and is compatible with most 1996 and newer vehicles. This tool allows users to read and clear Diagnostic Trouble Codes (DTCs), view live data streams, check I/M readiness status, and retrieve freeze frame data, helping to identify the cause of the Check Engine Light (CEL) and turn it off.

2. Ensure the vehicle's ignition is in the 'OFF' position.
3. Firmly plug the AL319's OBDII connector into the vehicle's DLC.
4. Turn the vehicle's ignition to the 'ON' position (engine off). The AL319 will automatically power on and begin communicating with the vehicle.

4.3 Viewing Live Data

Live Data allows you to view real-time operational parameters of the vehicle's engine. This can be useful for diagnosing intermittent problems or verifying repairs.

1. From the Diagnostic Menu, select 'Live Data' and press 'ENTER/EXIT'.
2. The scanner will display a list of available data parameters. Use the 'SCROLL' button to navigate through the list.
3. Parameters include engine RPM, vehicle speed, coolant temperature, and more.

4.4 Viewing Freeze Frame Data

Freeze Frame Data captures a snapshot of the vehicle's operating conditions at the moment a fault code was set. This provides valuable context for diagnosis.

1. From the Diagnostic Menu, select 'View Freeze Frame' and press 'ENTER/EXIT'.
2. If freeze frame data is stored, it will be displayed. If not, a message indicating no data will appear.

4.5 I/M Readiness Status

I/M Readiness indicates whether the various emissions-related systems on the vehicle are operating correctly and have completed their self-tests. This is crucial for emissions inspections.

1. From the Diagnostic Menu, select 'I/M Readiness' and press 'ENTER/EXIT'.
2. The display will show the status of various monitors (e.g., Misfire Monitor, Fuel System Monitor, O2 Sensor Monitor) as 'OK' (completed) or 'INC' (incomplete).
3. The patented One-Click I/M Readiness Key provides quick access to this function.

This function allows you to retrieve the Vehicle Identification Number (VIN), Calibration ID (CALID), and Calibration Verification Number (CVN) of the vehicle.

1. From the Diagnostic Menu, select 'Vehicle Info' and press 'ENTER/EXIT'.
2. The scanner will display the available vehicle information.

5. Maintenance

To ensure the longevity and optimal performance of your Autel AL319 scanner, follow these maintenance guidelines:

• Cleaning: Wipe the unit with a soft, damp cloth. Do not use abrasive cleaners or solvents.
• Storage: Store the scanner in a clean, dry environment away from extreme temperatures and direct sunlight.
• Cable Care: Avoid bending or kinking the OBDII cable excessively. Do not pull the cable to disconnect the scanner; always grasp the connector.
• Software Updates: Periodically check the official Autel website for software updates to ensure compatibility with the latest vehicle models and to improve functionality. The AL319 offers lifetime free updates.

6. Troubleshooting

If you encounter issues while using your Autel AL319, consider the following common solutions:

• No Power/Communication: Ensure the OBDII connector is securely plugged into the vehicle's DLC. Verify the vehicle's ignition is in the 'ON' position (engine off). Check the vehicle's fuse for the OBDII port.
• Error Message: If an error message appears, refer to the specific message on the screen. Ensure the vehicle is OBDII compliant (most vehicles after 1996).
• Cannot Erase Codes: Codes cannot be erased if the underlying fault is still present. Address the vehicle's issue first, then attempt to clear codes. Some manufacturer-specific codes may require advanced tools.
• No Freeze Frame Data: Freeze frame data is only stored when a fault code is set. If no codes are present, there will be no freeze frame data.
• Incomplete I/M Monitors: Some monitors require specific driving cycles to complete. Drive the vehicle under various conditions (city, highway) to allow monitors to run.

Important Note: The AL319 is a basic code reader and does not support advanced reset functions such as airbag reset, SRS, or electronic parking brake reset. If you are unsure about compatibility with your specific car model, please contact Autel support with your car's year and model before purchase.
