There are hundreds of diagnostic addresses and values you can pull up on the minidisplays on every piece of equipment, as well as diagnostic codes that have been more than sufficient to use to follow the diagnostic procedures the Deere provides in any case that I’ve ever dealt with. That diagnostic manual is another 10,000 page manual that deere supplies and if you’re bright enough, you can fix anything. The wire numbers, circuit diagrams, test procedures, etc, etc, etc are all in there, but most farmers can’t be arsed to buy a multimeter it would seem. Most farmers that bitch about R2R wouldn’t grease their own combine if they can help it, let alone replace a turbo.
There are a certain number of parts like stepper motors etc that have CanBUS addresses that need to be programmed into the controllers so they can address the part correctly over J1939. So in those rare cases, I’ve gotten a tech to drive by on their way to another call, and spent $50 having them sync up the address, it’s not difficult. We are able to buy the JDSA systems now but it’s very much not worth the cost, $26000 the last time I checked.
And you’re plain wrong about the GPS, I’ve swapped around antennas and moved around 2630 systems with no need to call anyone. I think they’re overpriced shit compared to what I can build myself with AgOpenGPS, but they work fine for the standard idiot.
obviously never touched JD equipment
Pretty sure I know which one of us that describes.
