What Diagnostic Scanner Do Mechanics Use?

Published by

Professional mechanics typically use advanced diagnostic scanners like Snap-on SOLUS, Autel MaxiSys, and Launch X431. These tools cost $2,000-$10,000 and offer comprehensive vehicle coverage, bi-directional controls, and module programming capabilities. Dealerships use manufacturer-specific tools like Ford IDS, GM Tech2, or Toyota Techstream for the deepest access to vehicle systems. For home use, learn how to do diagnostics yourself with affordable consumer scanners, or use your phone as a diagnostic tool. Compare professional diagnostic costs versus buying your own scanner.
