Key Features
The Autel MaxiCheck MX900 is built around a responsive 8-inch 1280×800 touchscreen and operates on the Android 11.0 platform. Powered by a Rockchip 3566 processor alongside 4GB of RAM and 64GB of storage, the manufacturer lists a diagnostic speed up to five times faster than previous generations. The tool is equipped with a high-capacity 7700mAh battery and supports both 2.4GHz and 5GHz Wi-Fi for seamless pre- and post-scan report printing.
Diagnostic capabilities are extensive, featuring over 3000 active tests for full bidirectional control over vehicle components. The scanner includes more than 40 service functions covering routine maintenance tasks like oil resets, ABS bleeding, and throttle body relearning. Crucially, it provides native support for CAN FD and DoIP protocols, allowing communication with newer vehicle networks without requiring external adapters.

Setup, Compatibility and Ownership
Setting up the Autel MaxiCheck MX900 requires connecting the device to a Wi-Fi network to download the initial software updates. The manufacturer lists a one-year free update period, after which the scanner retains its downloaded functionality even if the subscription lapses. Navigating the Android 11 interface is straightforward, and buyers should confirm their specific vehicle compatibility on the Autel coverage list before initiating complex resets.
Because this scanner supports over 3000 active tests, technicians can directly command actuators like fuel pumps, wipers, and throttle bodies. As a safety note, always consult the qualified service procedures in the vehicle’s factory manual before actuating mechanical or pressurized systems. Accessing the FCA Secure Gateway on 2018 and newer models requires an active AutoAuth account, which is managed separately from the Autel ecosystem.
How It Compares
When evaluating this tool against the older Autel MaxiCheck MX808S, the MX900 offers significant hardware improvements. The listed specifications indicate a jump from a 7-inch to an 8-inch screen, alongside the critical addition of native CAN FD and DoIP protocols. This makes the newer model far more capable for diagnosing recent GM, Volvo, and BMW platforms without requiring expensive adapter cables.
The MX900 is marketed as the US version of the Autel MaxiCOM MK900 diagnostic scanner, sharing identical firmware, software, and bidirectional capabilities. However, buyers prioritizing shop mobility should note that this is a strictly wired device. Those needing a Bluetooth VCI to move freely around the vehicle should look toward the wireless Autel MaxiCOM MK900BT instead.
Who Should Buy It?
This scanner is highly suited for independent technicians, mobile mechanics, and serious DIYers who need OE-level all-system diagnostics. The inclusion of 40+ service functions and robust bidirectional controls makes it an excellent choice for users performing routine maintenance, ABS bleeding, and sensor calibrations. The native CAN FD and DoIP support also ensures readiness for newer vehicle architectures.
Conversely, buyers who require advanced ECU coding, programming, or a wireless Bluetooth interface should skip this model. Entry-level users who only need to read and clear basic check engine lights will likely find the 3000+ active tests and advanced protocol support unnecessary for their limited scope of work.
Frequently Asked Questions
Does this scanner support CAN FD and DoIP?
Yes, the manufacturer lists native support for both CAN FD and DoIP protocols. This allows direct diagnostics on newer GM, Volvo, and BMW chassis without requiring separate adapter cables.
Is the Autel MX900 a wireless scanner?
No, the listed specifications indicate that the MX900 is a wired diagnostic tool. Buyers requiring wireless functionality should confirm the current configuration of the MK900BT model instead.
What happens when the software subscription expires?
The scanner comes with one year of free software updates. After the expiration date, the tool will continue to function normally with the last downloaded software version, though newer vehicle coverage will require a renewal.
Can this tool access the FCA Secure Gateway?
Yes, it supports FCA SGW AutoAuth access. You will need to register for a separate AutoAuth account to bypass the security module on 2018 and newer Chrysler, Dodge, Jeep, and Fiat vehicles.
The Autel MaxiCheck MX900 delivers a highly capable diagnostic solution for the 2026 market, bridging the gap between basic code readers and premium shop tablets. With its responsive Android 11 interface, extensive bidirectional controls, and modern protocol support, it handles complex repairs efficiently. While the wired connection limits physical mobility, the robust feature set and lack of an IP lock make it a reliable, long-term investment for diagnostic work.
