Discover how the Autel MaxiSYS Ultra S2’s new topology 3.0 feature revolutionizes diagnostics.

In this Motor Age Tech Tip Short, Keith Perkins showcases the powerful new topology 3.0 feature in the Autel MaxiSYS Ultra S2.

Using a 2015 BMW X5, he demonstrates how technicians can visualize and isolate diagnostic networks like CAN, FlexRay and Ethernet. The tool allows users to ping individual modules, such as the fuel pump controller, helping diagnose intermittent communication issues. Unlike other aftermarket scan tool features, this system provides detailed data like DTCs, node locations and terminating resistance.

With intuitive visuals and robust functionality, the Ultra S2 enhances efficiency and accuracy for any diagnostic technician. Watch the full Short to see it in action.
