Adapter
13 of 37 control units — including the engine — sit on the standard OBD pins, which any ELM327 v1.5+ adapter reaches. 14 more are on the slower interior bus (MS-CAN, pins 3/11): reaching those needs an adapter with an MS-CAN transceiver, such as the OBDLink MX+ or vLinker MC+. 10 sit on a second CAN or the body bus that only a vLinker MS switches to by itself (untested on hardware so far).
