Other OBD2 Vehicles

Not supported.

Gretio is an OEM level tool and only supports OEM level diagnostic protocols. It is incapable of reading “Generic OBD2” protocols. As such it can only work with vehicles it is designed for.

While a “OBD2 Protocol” could be added to Gretio, it would perform poorly. Gretio is optimized for Unified Diagnostic Services (UDS). Most OEMs do not use a pure implementation of UDS, so every make has to be implemented individually.

For “Generic OBD2” protocols you can use the standard “Obdlink” app found on iOS or Android. Their app is designed to work with standard OBD2 and works perfectly fine for those applications.
