I seem to have problems with nailing down the interface version of the OBD socket in my car.
Is it OBD, OBD2 or EOBD compatible? I know the differences between them in theory, but there is no solid info on which the car is equipped with. I'm looking at purchasing several items for my car and their description is usually "EOBD compatible".
Those items will connect via OBD socket but their purposes are quite different from one another so what I'm really asking is are those standards interchangeable in terms of socket pin assignments?
