Buying Guide: How to Choose the Best Autel Scanner
Diagnostic Depth: Code Reading vs. Bidirectional Control
Consider what you need from the scanner. A basic code reader like the Autel AL319 can read and clear diagnostic trouble codes (DTCs), show live data, and check I/M readiness. This is enough for many DIYers who want to turn off the check engine light and understand a simple fault.
If you are a professional or an advanced DIYer, you need bidirectional control. A bidirectional scanner can send commands to vehicle components, like activating a fuel pump or testing a cooling fan. This helps you confirm a part is faulty before you replace it. For a deeper dive, read our comparison of best bidirectional scan tools for 2026.
Vehicle Coverage and Protocol Support
Ensure the scanner covers the makes and models you work on. Autel scanners generally support a wide range of US, Asian, and European vehicles. However, newer protocols like CAN FD and DoIP are becoming common on vehicles from 2026 and later. If you work on newer GM, BMW, or Volvo models, look for a scanner that supports these protocols, such as the Autel MaxiCOM MK900BT.
Maintenance and Service Functions
Beyond diagnostics, many Autel scanners offer service functions like oil reset, ABS bleeding, EPB reset, and battery registration. These features are valuable for routine maintenance. If you handle a variety of repairs, choose a scanner with a broad set of service functions.

Hardware Performance and User Experience
A fast processor, ample memory, and a clear display make diagnostics smoother. Modern Autel scanners run on Android with high-resolution touchscreens. Look for models with quick boot times and responsive interfaces. Wireless connectivity adds convenience, letting you move around the vehicle while scanning.
