Topology Module Mapping

The X100 MAX scans all available vehicle modules and displays their diagnostic status in a color-coded tree map, revealing communication structures between modules. This significantly improves repair efficiency in professional workshops.

Advanced ECU Coding

Unlock hidden features, disable annoying functions, enhance vehicle performance, customize OEM settings, reprogram adaptive data after component replacement, and configure high-end models—all to improve fuel efficiency and ensure safe driving.

Bi-Directional Control for Precision Diagnostics

As a true bi-directional tool, the X100 MAX sends commands to ECUs, reads ECU data, and monitors actuator operation through active tests—helping you quickly isolate faults. For example, if a fuel pump failure causes ignition issues, you can toggle the pump on/off via the X100 MAX to determine whether the problem lies with the pump, wiring, relay, or control signal—without disassembly.
Note: Available functions vary by vehicle.
