Smoother Workflow with Seamless Switching & Multitasking

• Keep VIN data visible as you switch between functions, and run two compatible apps at once to maintain your momentum throughout the job.

A Faster Route to the Big Picture

• Color-coded topology mapping gives you an at-a-glance view of vehicle communication, while parallel system scans help cut diagnostic time by up to 80%.

Compare More Data. Find the Cause Faster.

• Compare parameters from multiple ECUs at once with Live Data Fusion, making it easier to identify cause-and-effect relationships during road tests.

Go Deeper to Find Difficult Faults

• ECU Ping and ECU Center are currently under development and will be available in an upcoming release.

See How Vehicle Systems Connect

• OBD Graphical Diagnostics visualizes system structure, component locations, and the relationships among sensors, actuators, and ECUs—going beyond codes and data lists.
