OBD Fusion supports all OBD2 and EOBD vehicles sold worldwide. If you're not sure whether your vehicle is OBD2 or EOBD 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 can also connect to some JOBD vehicles that don’t support standard OBD2 protocols.
Electric vehicles (EVs) are not required to have OBD2 diagnostics since they are emissions exempt. If you are interested in using OBD Fusion on an EV, contact us first to inquire about support.
