Autel MaxiCheck MX900 Review: Dealership-Level Diagnostics at Home

Basic code readers only tell part of the story on a modern car, so I looked at the Autel MaxiCheck MX900, a scanner built for all-system diagnostics rather than just checking the engine light, to see how close it gets to dealership-level tools.

What You Get With the MX900

The MX900 ($519.00, down from $599.00, US version with local warranty) runs on an 8-inch capacitive touchscreen at 1280x800 resolution and covers roughly 95% of vehicle systems through Auto VIN and automatic scanning, including ABS, SRS, ECM, TCM, brakes, BCM, and TPMS. It supports live data streaming and active bi-directional tests like injector tests, fuel pump control, and A/C cycling.

Service Functions and Real-World Use

Beyond reading and clearing codes, the MX900 packs more than 40 service functions, including oil reset, electronic parking brake reset, steering angle calibration, and battery registration — the kind of routine maintenance resets that usually require a trip to the dealer. One reviewer did note it couldn't recalibrate a specific GM steering sensor as advertised, which is worth keeping in mind since coverage can vary by exact make, model, and system.

Pros and Cons

Pros

• Covers roughly 95% of vehicle systems, not just the engine
• 40+ service functions replace several dealer-only resets
• Large 8-inch touchscreen makes navigation straightforward
• 4.8-star rating from reviewers, with US local warranty support

Cons

• Some advanced calibrations can vary in coverage by specific vehicle
• Significant investment compared to a basic code reader

Final Verdict

For serious DIYers or independent shops that need real system-wide diagnostics, the MX900 delivers capability that goes well beyond a basic scanner. Check out the Autel MaxiCheck MX900 and browse Autel-US's full range of diagnostic tools for current pricing.
