Frequently asked questions
What is a heavy duty OBD2 scanner?
A heavy duty OBD2 scanner is a diagnostic tool designed for professional use. It can access all vehicle systems and perform advanced functions like bidirectional testing and coding. These scanners are built to withstand daily shop use and provide comprehensive data.
Can a heavy duty scanner read commercial vehicle codes?
Some heavy duty scanners are specifically designed for commercial vehicles. They support protocols like J1939 and can access heavy duty systems. The Foxwell NT809CV is an example of a scanner that specializes in trucks and buses.
Do I need a subscription for updates?
Update policies vary by brand. Some scanners offer free updates for a limited time, while others require a subscription after the first year. Always check the cost and frequency of updates before purchasing.
What is bidirectional control?
Bidirectional control allows you to send commands to vehicle components to test them. For example, you can activate a fuel pump or cycle an actuator. This is essential for diagnosing intermittent issues without manual testing.
How important are special functions?
Special functions like oil reset, EPB, and SAS calibration are crucial for modern maintenance. Many vehicles require these resets after servicing. A professional scanner should include common special functions for the brands you work on.
Can I use a smartphone app scanner for professional work?
Smartphone scanners like BlueDriver Pro offer many professional features but have limitations. They lack advanced coding and programming. They are suitable for quick diagnostics but may not replace a full featured standalone scanner for complex repairs.
What is the difference between OBD2 and all system diagnostics?
OBD2 diagnostics only access the engine control module for emissions related data. All system diagnostics allow you to read codes from ABS, airbag, transmission, and other modules. Professional work requires all system access.
Are expensive scanners worth the investment?
For a busy professional shop, a high end scanner can pay for itself through time savings and expanded service capabilities. Advanced features like ADAS calibration may require specialized equipment, but they open up new revenue streams.
Do all scanners cover all vehicle makes?
No, coverage varies. Some scanners have broad global coverage, while others are specialized for certain regions. Check the manufacturer’s website for a list of supported makes and models.
What is the typical lifespan of a professional scanner?
With regular updates, a professional scanner can last many years. The hardware is durable, but software support may eventually be discontinued. Choose a brand with a strong update history.
The bottom line
For most professional mechanics, the Autel MaxiCOM MK808BT offers the best balance of features, ease of use, and value.
