Key Features of Autel MaxiCheck MX900 Scanner

1. Extensive OEM-Level All System Diagnostics

The Autel MaxiCheck MX900 Scanner accesses every major vehicle system — engine, transmission, ABS, SRS, TPMS, and more. It reads and clears fault codes and displays live data such as RPM, fuel trims, and temperatures in text, graphs, and analog gauges. This all-system capability ensures you won’t miss hidden faults and can track real-time sensor data to diagnose issues effectively.

Benefit: Saves time and money by allowing deep diagnostics without multiple tools.

2. 3000+ Active Tests & 40+ Service Functions

With over 3000 active tests, this scanner can command vehicle components to perform specific actions — like operating ABS pumps, solenoids, wipers, and valves — to identify faulty parts. The 40+ service functions cover common maintenance tasks such as oil reset, EPB (electronic parking brake) reset, SAS (steering angle sensor) calibration, battery registration, throttle reset, ABS bleeding, injector coding, and headlamp adjustments.

Benefit: Enables hands-on diagnostics and maintenance, reducing the need for dealer visits.

3. Bi-Directional Control & Active Testing

The MX900’s bi-directional capability lets you send commands directly to the vehicle’s ECU, actively driving actuators to test their function. This feature is particularly valuable when troubleshooting intermittent or complex issues, providing a higher degree of control than standard scan tools.

Benefit: Pinpoints problem parts quickly, improving diagnostic accuracy.

4. CAN FD and DoIP Protocol Support

Supporting the latest communication protocols ensures compatibility with modern vehicles, including those with advanced electronic architectures. CAN FD (Controller Area Network Flexible Data-rate) and DoIP (Diagnostics over Internet Protocol) support future-proof the tool.

Benefit: Works efficiently on new-generation cars and trucks.

5. Auto VIN Detection and Auto Scan 2.0 Technology

The scanner automatically reads the vehicle identification number (VIN) and performs a full system scan with minimal input. This speeds up the diagnostic process and reduces errors.

Benefit: Quick, accurate vehicle identification and comprehensive assessment.

6. Large 8-inch Touchscreen with Android OS

The bright, high-resolution touchscreen provides clear data visualization in multiple formats. The Android operating system makes navigation smooth and intuitive, while the device’s ergonomic design offers comfort during prolonged use.

Benefit: Improved user experience and ease of use.

7. Multilingual Support and Wi-Fi Printing

Benefit: Enhances communication and professionalism in diverse settings.

How Does Autel MaxiCheck MX900 Scanner Perform?

Real-World Scenario 1: Diagnosing a Persistent Check Engine Light

In one test, I used the MX900 to diagnose a check engine light on a mid-range sedan. The scanner quickly connected via OBD2, auto detected the VIN, and scanned all systems within minutes. It pulled multiple fault codes related to oxygen sensors and fuel trims. The live data graphs helped me see fluctuating sensor values in real time, which confirmed an intermittent sensor fault. Clearing the codes and re-scanning was straightforward, and the scanner maintained a stable connection throughout.

Real-World Scenario 2: Performing Bi-Directional Active Tests on ABS System

On a vehicle with ABS issues, I used the MX900’s active test feature to engage the ABS pump and solenoids. This hands-on function allowed me to verify the operation of each component without needing to dismantle parts blindly. The feedback clearly showed which actuator was failing, speeding up the repair process significantly.

Real-World Scenario 3: Maintenance Service Tasks

I performed an electronic parking brake reset and battery registration on two different cars. The MX900 guided me step-by-step through each service, making the tasks easy even without prior experience. The throttle calibration and injector coding functions also performed flawlessly on compatible vehicles.

Performance Analysis

The Autel MaxiCheck MX900 Scanner consistently delivered fast response times, with a claimed 5X faster running speed than previous models evident in daily use. The Android interface felt fluid and stable, and the thick, abrasion-resistant OBD cable ensured reliable data transmission. The only limitation is the tool’s vehicle compatibility — users must confirm their VIN is supported to avoid disappointment.

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.”
