OBD2 code readers and scan tools — handheld scanners, Bluetooth adapters and professional diagnostic tools.
OBD2 code readers and scan tools read fault codes from the car's computer when the check engine light comes on, which helps drivers and mechanics find problems quickly and avoid unnecessary repairs. Basic code readers show and clear engine fault codes, while advanced scan tools read ABS, airbag, transmission and other systems, show live data and perform service functions such as oil light resets and battery registration. Bluetooth OBD2 adapters connect to a phone app. Check compatibility with your car's make, model and year before ordering. All petrol cars sold in the US since 1996 and in Europe since 2001 support OBD2. Diesel cars in Europe support it from 2004. Scan tools pay for themselves after one avoided garage diagnostic fee.
