Thanks for posting, your engine bay looks tops. I'm fairly sure you posted the wrong video though, I think you were supposed to upload the one from your "private test road" where it's banging off the limiter with the gate open? -
This is something to be careful of. I did a bit of digging on the NM35, as I spend a lot of time on near brand new cars and CANBus related stuff, which uses the same "OBD2" plug for a fair chunk of making my life easy. The NM35, does NOT support OBD2. The data pin is actually on Pin3, which is a manufacturer specific pin, and requires Consult3 to connect to the NM35. Your low voltage, is either because the NM35 doesn't have 12V to the constant power pin on the J1962 (OBD2) connector, OR, it is attempting the standard comms, (CanBus, K Line, etc) and can't see any voltage on those pins. Some people have had success accessing SOME data from the vehicle on OBD2 specification, using a module that supports KPW. My assumption, like Duncan has stated, it will likely actually be JOBD, where there is some cross over with the OBD2 and JOBD standards. Note, lots of "OBD2" dongles, do NOT support KPW, which is what you need for a lot of Japanese vehicles of this era (And even up until recent years!), EG, Subaru, Suzuki, etc. The end of this thread is probably worth a read, as some people did find a way to get a display up in the NM35 recently, looks like someone implemented all the stuff needed to make it work. (The right protocols).
