OBD2 Code Readers

OBD2 code readers are the simplest way to check engine fault codes and warning lights on compatible vehicles. These tools connect through the vehicle’s standard diagnostic port and are mainly used for engine-related fault codes, live data and basic checks.

This collection includes simple plug-in code readers, Bluetooth adapters, app-based tools and monitoring devices such as ScanGauge. They are a good option if you want quick access to engine codes, fuel data, trip information or app-based vehicle data without needing full-system diagnostics.

If you need access to ABS, SRS airbags, transmission, electronic parking brake, battery management or service reset functions, look at our single make or all makes scan tools instead.
