Buying Guide
Your Skill Level and Diagnostic Needs
Are you a DIYer who just wants to clear a check engine light, or a professional mechanic who needs to perform advanced diagnostics? Ancel offers entry-level code readers like the ANCEL AD310 Classic Enhanced Universal OBD II, which is perfect for basic engine diagnostics. Autel, on the other hand, provides a wide spectrum from the simple Autel AL319 Professional OBD2 Scanner to the professional-grade Autel Scanner MaxiCheck MX808S with bidirectional capabilities. Your skill level should guide your choice.
If you are new to car repair, a basic code reader is a great start. For more experienced users, a bidirectional scan tool that can perform active tests and service functions offers much deeper insight. For electric vehicle owners, we have a dedicated guide on the best OBD2 scanner for electric cars.
Bidirectional Control and Active Tests
Bidirectional control is a game-changer for diagnosing complex issues. It allows you to command components like fuel injectors, cooling fans, or ABS pumps to activate and verify their operation. Autel scanners like the Autel Scanner MaxiCOM MK900BT Bidirectional Tool and the Autel Scanner MaxiCOM MK900TS Scanner excel here, offering thousands of active tests. Ancel also offers bidirectional control in its heavy-duty scanners, such as the ANCEL X7HD PRO Heavy Duty Truck Scanner with 42, which is ideal for diesel trucks.
This feature helps you confirm a faulty part before replacement, saving time and money. If you work on a variety of vehicles, having a tool with extensive bidirectional coverage is invaluable.
Service Functions and Special Features
Modern vehicles require more than just code reading. Service functions like oil reset, ABS bleeding, EPB (electronic parking brake) reset, and battery registration are essential for routine maintenance. Autel scanners are known for their extensive list of 28 to 40+ service functions, as seen in the Autel Scanner MaxiCheck MX808S and the Autel Scanner MaxiCOM MK900. Ancel also provides a robust set of service functions, particularly in their heavy-duty models, including DPF regeneration and injector coding.
Consider the specific services you perform most often. If you work on diesel trucks, Ancel’s heavy-duty focus might be a better fit. For passenger cars, Autel’s comprehensive service suite is hard to beat. For a deeper look at Autel’s entry-level options, read our Autel AL319 review.
Vehicle Coverage and Protocol Support
Your scanner must be compatible with the vehicles you work on. Autel scanners offer broad coverage for over 150 brands, including domestic, Asian, and European models. They also support the latest protocols like CAN FD and DoIP, which are found on newer vehicles. Ancel scanners, while also covering many brands, have a strong emphasis on heavy-duty trucks and diesel engines, supporting J1939 and J1708 protocols. The Autel AL549 OBD2 Scanner Code Reader with ABS is a good choice for basic OBD2 and ABS diagnostics on many cars, while the ANCEL V6HD Heavy Duty Truck Scanner, Active Test is built for commercial vehicles.
Always check the manufacturer’s compatibility list before purchasing. For a general overview of OBD2 scanners, visit our OBD2 scanners category page or the code readers section.
