The Autel AL619 OBDII scanner is a valuable tool for diagnosing vehicle issues, particularly with its comprehensive OBDII functionalities. Among these, Mode 6, or the On-Board Monitor Test, stands out for its ability to provide crucial insights into the vehicle’s emission control systems. This article delves into the specifics of Autel Al619 Mode 6, explaining its purpose, functionality, and benefits for both DIY enthusiasts and professional mechanics.
Autel AL619 Features and Functionality.
Understanding Autel AL619 Mode 6
Mode 6 on the Autel AL619 allows users to access the results of the vehicle’s continuous emission monitoring tests. These tests, run by the on-board computer, constantly evaluate the performance of various emission-related components. Autel AL619 Mode 6 provides access to this data, displaying the results of specific monitor tests, such as the catalytic converter, oxygen sensors, and the evaporative system (EVAP).
Why is Autel AL619 Mode 6 Important?
Accessing On-Board Monitor Test results with the Autel AL619 Mode 6 offers several advantages:
- Diagnose Emission Issues: Identify potential problems within the emission control system, helping pinpoint faulty components like a malfunctioning catalytic converter or a failing oxygen sensor.
- Verify Repairs: After completing emission-related repairs, Mode 6 confirms the effectiveness of the fix by showing if the monitors have run and passed their tests. This is crucial for ensuring the vehicle meets emission standards.
- Smog Test Readiness: Before a smog check, Mode 6 helps determine if the vehicle’s emission monitors are ready. Incomplete monitor tests can lead to a failed smog inspection.
- In-Depth Diagnostics: Mode 6 provides a more in-depth look at the emission system’s health compared to simply reading diagnostic trouble codes (DTCs). It reveals underlying issues that may not yet have triggered a DTC.

Interpreting Autel AL619 Mode 6 Results
Understanding the results displayed in Mode 6 is vital for accurate diagnosis. Common statuses include:
- Complete/Passed: The monitor has run its test and the system is functioning correctly.
- Incomplete/Not Ready: The monitor has not yet completed its test cycle. This can happen after recent repairs or if the vehicle hasn’t been driven under specific conditions required for the monitor to run.
- Failed: The monitor has detected a problem within the system it’s monitoring. Further diagnosis using other OBDII modes or diagnostic procedures may be necessary.
Conclusion
The Autel AL619 Mode 6 On-Board Monitor Test is a powerful feature that enables in-depth analysis of a vehicle’s emission system. By understanding how to use and interpret the results, users can efficiently diagnose emission problems, confirm repairs, and ensure smog test readiness. This functionality makes the AL619 an essential tool for anyone working on modern vehicles.
