Key Features of the Autel AL519 OBD2 Scanner

The Autel AL519 is packed with features that make it stand out as a comprehensive diagnostic tool:

• Full OBDII Functions (Modes 1 to 10): You can perform a complete OBD2 diagnosis, including reading codes, erasing codes, viewing live data, and more.
• Quick DTC Lookup and Live Data in Text & Graph: This allows you to quickly identify problems and monitor real-time performance.
• O2 Sensor Testing & EVAP Leak Test: Diagnose emissions-related issues easily and locate faulty parts like the O2 sensor.

All 10 Modes of OBDII Tests: What You Need to Know

The Autel AL519 performs all 10 modes of OBDII tests, providing a comprehensive vehicle diagnosis. These include:

1. Read Codes – Identifies and displays error codes.
2. Erase Codes – Clears stored diagnostic trouble codes.
3. View Live Data – Displays real-time sensor readings in both text and graph.
4. Smog Check – One-click readiness test for emissions compliance.
5. Freeze Frame Data – Shows parameters at the moment a fault is detected.
6. O2 Monitor Test – Tests the oxygen sensor's functionality.
7. On-Board Monitor Test – Checks the performance of internal systems.
8. Component Test – Pinpoints specific faulty components.
9. Vehicle Information – Retrieves VIN, CIN, and other info.
10. Module Present – Identifies available system modules.

Live Data Graphing & Freeze Frame Data

Live data graphing allows users to view and analyze real-time vehicle data. This can help diagnose issues such as misfires, fuel efficiency problems, or sensor malfunctions. Freeze frame data, on the other hand, captures the vehicle’s operating conditions when a trouble code is triggered, making it easier to pinpoint the issue.

DTC Definition Lookup: A Game-Changer

One of the most frustrating aspects of using some OBD2 scanners is the need to look up diagnostic trouble codes (DTCs) online. The AL519 eliminates this hassle by providing an integrated DTC Lookup feature, which shows the definitions and descriptions of codes instantly.

Turning Off the Check Engine Light (CEL)

The dreaded Check Engine Light (CEL) can be a source of anxiety for many vehicle owners. With the Autel AL519, you can easily diagnose the cause of the light and turn it off after resolving the issue. The tool performs thorough OBDII diagnostics, including live data monitoring and component testing, to identify the root cause and fix the problem.

Enhanced New Features of the AL519

Autel has equipped the AL519 with a number of new features designed to make diagnostics even easier:

• One-Click Smog Check: Quickly assess whether your vehicle is ready for emissions testing.
• AVOmeter: Test voltage, continuity, and current at your fingertips, perfect for diagnosing electrical issues.

Wide Vehicle Compatibility

The AL519 supports a wide range of vehicle protocols, including KWP2000, ISO9141, J1850 VPW, and CAN, making it compatible with most post-1996 U.S., post-2006 EU, and post-2009 Asian vehicles. 

Lifetime Free Updates and Printing Data

The AL519 comes with lifetime free updates, ensuring your scanner remains up-to-date with the latest software. Additionally, it offers a data printing function, allowing users to print diagnostic reports for further analysis via a PC or laptop.

The Cost-Effective and Efficient Solution

With all its advanced features, the Autel AL519 provides excellent value for money. Compared to more expensive OBD2 scanners, the AL519 delivers professional-grade diagnostics at a fraction of the cost.
