The Starwis ELM327 is a plug-and-play Bluetooth OBD-II adapter that reads and clears engine fault codes, shows freeze frame data and runs I/M readiness checks. It pairs with a phone over Bluetooth 5.1 and works with third-party OBD apps that graph live sensor data. It covers nine protocols on most gasoline cars sold after 1996 in the US, 2002 in the EU and 2008 in Asia. It is a budget adapter for DIY code reading, not a factory-level tool: it does not handle ABS, airbag or body modules, and it will not work on hybrids, EVs or other new-energy vehicles.
