OBD Fusion is a vehicle diagnostics tool that connects to OBD-II and EOBD vehicles. Not sure if your vehicle is OBD-2, EOBD or JOBD compliant? See this page for more information: https://www.obdsoftware.net/support/knowledge-base/how-do-i-know-whether-my-vehicle-is-obd-ii-compliant/. OBD Fusion works with some JOBD compliant vehicles and in some cases requires modifications to the connection settings in the app. Please contact us for more information.
You must have a compatible scan tool to use this software. For recommended scan tools, see our website https://www.obdsoftware.net/software/obdfusion. Please note that cheap ELM clone adapters can be unreliable. OBD Fusion can connect to any ELM 327 compatible adapter, but the cheap clone adapters tend to have slow refresh rates and might disconnect randomly.
