Scan Tool Software
A digital program that reads and interprets vehicle diagnostic data.
Scan tool software communicates with vehicle ECUs through the OBD-II interface, reading data such as RPM, sensor voltage, and fuel trims. Advanced versions allow bi-directional control to activate components for testing. Many software suites include graphing, logging, and remote support features. They help technicians perform deep diagnostics across multiple brands. Regular software updates ensure compatibility with new models and systems. Proper use enhances repair accuracy and saves diagnostic time.
