OBD2 Code Info app is a mobile application that provides users with detailed information on the meaning, causes, and possible solutions to diagnostic trouble codes (DTCs) generated by their vehicle's On-Board Diagnostic system. The app connects to the vehicle's OBD2 port using a Bluetooth or Wi-Fi adapter and retrieves DTCs, which it then decodes and presents to the user in an easy-to-understand format. The app may also offer additional features, such as the ability to clear DTCs, monitor live sensor data, and access manufacturer-specific codes. With an OBD2 Code Info app, users can quickly diagnose and troubleshoot issues with their vehicle, potentially saving time and money on costly repairs.
