Key Features of Autel MaxiCheck MX900 Scanner

1. 3000+ Active Tests with Full System Diagnosis

The MX900 offers over 3000 active tests that allow you to interact directly with vehicle components such as ABS modules, fuel injectors, and valves.

How Does Autel MaxiCheck MX900 Scanner Perform?

Real-World Diagnostic Speed and Accuracy

In my experience, the MX900’s auto VIN detection and Auto Scan technology delivered diagnostics rapidly. Connecting to vehicles like Ford and Chrysler models, the scanner identified all trouble codes and displayed live data swiftly. The 5X faster processor ensured no lag while browsing through menus or running active tests.

The fault code readings were precise, and clearing codes was instantaneous. The bidirectional control tests allowed me to activate solenoids and valves to verify component functionality, which helped isolate issues faster than with standard readers.

Usability in Workshop and On-Vehicle Settings

The device’s large touchscreen and ergonomic design made it comfortable to hold and operate inside tight engine bays. The thick, abrasion-resistant OBD cable added durability and ease of connection in rough environments. The flip-up stand at the back was a handy feature to prop the scanner up while working.

Navigation felt intuitive thanks to the Android interface, and accessing live data in text, graph, or analog formats gave me flexibility depending on the situation.

Service Functions in Action

I tested core service functions such as oil reset, battery registration, and SAS reset on compatible vehicles. Each function worked smoothly and completed within expected time frames. The injector coding and ABS bleeding tools were particularly helpful during brake and fuel system repairs.

Limitations and Compatibility Checks

While the MX900 covers a broad range of vehicles, I recommend sending your VIN to the supplier for compatibility confirmation before buying. Some advanced functions may not work on all models, especially outside mainstream makes. However, for supported vehicles, the scanner performed very close to OEM-level tools.

What Customers Are Saying About Autel MaxiCheck MX900 Scanner

Customer Review: “Super easy to use, nice bright screen and android operating system. Makes my job diagnosing automotive problems a breeze. Nice quality heavy duty feel and ergonomic grips on the side. The flip up stand on the back is great. It’s portable and easy to use inside a vehicle. The OBD cable is thick and abrasion resistant. So far I’ve had a blast looking at values and graphs that I’ve previously not been able to see. I’ll definitely be upgrading in years to come with another Autel unit because of their quality.”

Customer Review: “I wish I would have spent the extra money for the Bluetooth model, but it’s really not necessary. I use very expensive test tools (electrical field) at work and this MX900 has the fit and finish of one of those products. I used the MX900 on a Ford and Chrysler with the same success. Very happy with this piece of technology, it paid for itself on the Prius brake booster job alone.”

Customer Review: “Simple to use, simple to understand. Great quality case. I have a 2018 GMC diesel van that was constantly having to go to the shop to be re-genned because it would not regen itself. This device has been great and I would highly recommend it.”
