MK900BT vs MK900 Specs Compared

wireless connectivity

Edge: Autel MaxiCOM MK900BT 8-inch Scanner

The Autel MaxiCOM MK900BT uses a V150 Bluetooth connector for wireless diagnostics. This setup allows for a diagnosis range of up to 33 feet, giving you more flexibility to move around the vehicle while working. The Autel MaxiCOM MK900 relies on a stable cable connection instead. This wired approach eliminates Bluetooth lag and ensures no data drop-off during complex procedures. While the MK900BT offers greater mobility, the MK900 provides a more consistent link for critical tasks. You must choose between the convenience of wireless range or the reliability of a direct cable connection for your specific workflow needs.

screen size

Edge: Tie

Both scanners feature an 8-inch display. This screen size is significantly larger than the 7-inch screens found on older models like the MK808S or MK808Z. The larger display provides a bigger UI view, making data waveforms sharper and menus easier to read. This extra screen real estate allows you to see more information at once without zooming in. Since both the MK900BT and MK900 share this identical 8-inch hardware specification, there is no difference in visual clarity or viewing area. You get the same comfortable diagnostic experience on both devices.

active tests

Edge: Tie

Both the Autel MaxiCOM MK900BT and the Autel MaxiCOM MK900 offer over 3000 active tests. This bidirectional capability allows you to send commands to ECUs and monitor actuators, helping you quickly locate faulty components. This is a major upgrade from older models that only provided around 50 tests. The extensive list covers windows, mirrors, sunroofs, wipers, fuel injectors, coolant fans, AC clutches, and more. Since both tools share this identical specification, you have access to the same comprehensive list of functional tests for diagnosing and repairing vehicle systems.

reset functions

Edge: Tie

Both scanners provide 40+ hot services for over 150 makes. This includes essential resets like oil service, ABS bleeding, SAS calibration, injector coding, SRS, throttle reset, gearbox reset, and battery registration. The MK900BT and MK900 also add 12+ advanced resets, such as rain/light sensor reset and HVAC calibration. This coverage works on over 10,000 vehicles from 1996 to 2026. Since both tools offer the same 40+ reset functions, you can perform the same maintenance tasks on both devices without any difference in service capability.

protocol support

Edge: Tie

Both the Autel MaxiCOM MK900BT and the Autel MaxiCOM MK900 support the newest CAN FD and DoIP protocols. CAN FD works for GM vehicles from 2019 and newer, while DoIP supports Volvo from 2018, Jaguar and Land Rover from 2017, and BMW F and G chassis models. This protocol support eliminates the need for separate adapters for these specific brands. Since both scanners include these advanced protocols, you get the same compatibility with modern vehicle communication standards on both devices.
