Frequently asked questions
What is the difference between OBD2 and professional scanners?
OBD2 scanners are designed to read generic engine codes on all vehicles that comply with OBD2 standards. Professional scanners go beyond that, reading manufacturer-specific codes from all systems and offering advanced features like bidirectional controls and special functions. They are more expensive but essential for full diagnostics.
Can I use a portable scanner for coding and programming?
Some portable scanners, like the Autel MK808BT TS and Launch X431 V+, support coding and programming for select modules. However, high-level programming often requires a more advanced tool, and some functions may only be available for certain makes. Always check the scanner’s capabilities.
Do I need an internet connection for these scanners?
Most scanners do not require an internet connection to perform basic diagnostics. However, internet access is often needed for software updates, and some features like repair reports or online coding may require a connection. The included apps might also use the internet for additional information.
Will these scanners work on all car makes and models?
The coverage varies by scanner. High-end tools like Autel and Launch claim wide coverage for domestic, Asian, and European vehicles. Budget scanners often have limited coverage, especially for European makes. Check the product specifications or the manufacturer’s website for a list of supported vehicles.
What is a bidirectional scan tool?
A bidirectional scan tool can send commands to vehicle components to test them. For example, it can command the cooling fan to turn on or the fuel injector to pulse. This allows you to verify that the component is working correctly without needing to manually trigger it. It is a key feature for professional diagnostics.
Can I update the software on these scanners?
Yes, most professional scanners support software updates. Autel and Launch offer online updates for several years with purchase. BlueDriver updates its app for free. FOXWELL and Innova also provide updates. Always check the update policy before buying.
What is the advantage of a wireless scanner over a wired one?
Wireless scanners, like the Autel MK808BT TS and BlueDriver, allow you to move freely around the vehicle while data is displayed on a screen. They reduce cable clutter and are easier to use in cramped areas. However, they rely on battery life and a stable Bluetooth or Wi-Fi connection.
Do I need a professional scanner if I only work on my own car?
If you only need to read and clear engine codes, a basic OBD2 scanner is sufficient. But if you want to perform more advanced diagnostics, such as checking transmission or ABS issues, a professional-grade scanner offers more value. Consider your long-term needs and the age of your vehicle.
How do I choose between a handheld scanner and a tablet-based one?
Handheld scanners are compact and often have physical buttons, which some technicians prefer for quick use. Tablet-based scanners, like the Launch X431 V+, have larger screens and are more intuitive to navigate. Tablets offer more screen space for live data, but they are bulkier and may be more fragile. Choose based on your workspace and preference.
The bottom line
For a professional who needs a reliable, portable scanner that can handle almost any job, the Autel MaxiCOM MK808BT TS is the clear winner. It offers a rare combination of full system coverage, bidirectional controls, and coding capabilities in a wireless handheld package. If your budget is tighter and you focus primarily on engine diagnostics, the FOXWELL NT301 is a solid choice that will serve you well. For those who want the largest display and most advanced features, the Launch X431 V+ 4.0 is worth the investment. Choose the Autel for the best balance of power and portability.
