SINCE 2004--Professional Auto Diagnostic Factory

The best scan tools essentially provide you with a “one stop shop” that includes code and data reading functionality, advanced knowledge bases and troubleshooting tips, and a built-in scope and other meters. Some of these tools, like the professional-grade Snap-On MODIS, are prohibitively expensive, but they provide you with all of the tools you need to identify, test, and diagnose failed components.
