Why Use an OBD2 Scanner?

Modern vehicles are equipped with onboard diagnostic systems that track hundreds of performance parameters. When something goes wrong, a Diagnostic Trouble Code (DTC) is stored and the check engine light illuminates. With this scanner, you can read those codes immediately, understand what's wrong, and clear the warning light after repairs — saving you time and money. Learn more about vehicle emissions and onboard diagnostics at the U.S. Environmental Protection Agency (EPA) OBD information page.
