Buying Guide
Bidirectional Control and Active Tests
Bidirectional control is a game-changer for diagnostics. It allows you to send commands to vehicle components, like activating the fuel pump or testing the cooling fan, without using the vehicle’s controls. This helps you quickly pinpoint faulty parts. Both LAUNCH and Autel offer extensive bidirectional capabilities, but the number of active tests varies. The Autel Scanner MaxiCheck MX808S offers over 3,000 active tests, while the LAUNCH X431 PRO3 also provides robust bidirectional control. For serious diagnostics, look for a scanner with a wide range of active tests.
Service Functions and Coverage
Modern vehicles require specialized service functions like oil resets, ABS bleeding, and battery registration. The number of service functions can make a big difference in your workflow. Autel scanners like the MaxiCOM MK900BT offer 40+ service functions, while the LAUNCH X431 PROS V 5.0 provides over 38 reset services. Consider the specific services you need most, such as TPMS reset or injector coding, and ensure the scanner covers them for your vehicle brands. Our autel MaxiIM IM508S pro review covers another tool with extensive service options.
Vehicle Coverage and Compatibility
No scan tool works on every vehicle. Coverage depends on the make, model, and year. Autel scanners typically cover over 200 brands, while LAUNCH tools cover 200,000+ models. Both support newer protocols like CAN FD and DOIP for modern vehicles. Check compatibility with your specific vehicles, especially for FCA (Fiat Chrysler Automobiles) models with SGW (Secure Gateway) or Renault models. The Autel Scanner MaxiCOM MK808S and LAUNCH X431 PRO3 both support FCA AutoAuth.
Hardware and User Experience
A scanner’s hardware affects speed and ease of use. Look for fast processors, ample RAM, and a responsive touchscreen. Autel models like the MaxiCheck MX808S use a Rockchip RK3566 CPU with 4GB RAM and Android 11, while LAUNCH scanners often run Android 10 with 2.0GHz quad-core processors. Screen size matters too: the LAUNCH X431 PRO3 has a 10.1-inch display, while Autel’s MK808S has a 7-inch screen. A stable connection, whether wired or wireless, is crucial for reliable diagnostics.
Final Thoughts
Choosing between LAUNCH and Autel ultimately depends on your specific needs and budget. If you are a professional shop needing advanced features like ECU coding and topology mapping, the Launch X431 PRO3 (V+ V5.0) is a powerhouse. For a more affordable option with excellent bidirectional control and service functions, the Autel Scanner MaxiCheck MX808S is a fantastic choice for both DIYers and small shops. Both brands deliver reliable, professional-grade diagnostics, so you can confidently tackle any vehicle issue.
