How do you talk to an XR4140?

[strantor]

I got my brand new XR4140H home the other day (my very first tractor) and immediately started pulling panels off and examining the guts. I was delighted to find an actual OBD-II port on it, not the weird round connector, and even more delighted to find that my little Bluetooth ELM327 dongle connected right up to it and I was immediately able to read several PIDs in the Torque app. Pretty cool. My $200 Bosch OBD scanner wouldn't talk to it but my $12 Chinese Amazon special would. I guess Bosch wants more money for bilingual scanners.

Anyway, I was wondering what is the official/unofficial tool to interface with and perform dangerous meddling in the brains on this tractor? To do things beyond reading DTCs and PIDs. Not that I'm going to be doing tuner stuff to my brand new warrantied tractor or anything, but I'm just nerdy like that, and I want to know that if I ever want to, I can. Google suggests "IHI Shibaura Electronic Service Tool" which seems to be pirated software only available from dubious "vendors" in 3rd world countries, with no description of what the software does or what hardware/models it applies to. Is there something out there which is not top secret dealer-only special sauce? I know these aren't sports cars and there's probably not a big market for things that talk to it, but still, they put these Shibaura engines into everything, seems like someone, somewhere, would have come up with something.

Also I'm curious about what other systems are talking to each other in there. There's not much to a tractor except the engine, so I'm not expecting there to be an ABS controller, BCM, etc. but I'm curious what actually is there, other than the ECU. Any CANBUS pressure/valve position sensors? Anything for the HST transmission? I don't have a service manual yet, otherwise I would just look it up.


Side note, My brand new tractor, according to the Torque app, is throwing code P0374 - Powertrain "Timing reference high resolution signal 'A' no pulse." Not sure what to make of that. Maybe something is being miscommunicated? It comes back immediately when cleared, but there is no MIL on the dash panel, and the Cummins Fault Advisor app says there are no DTCs set.

Any references you see out there to Shibaura IHI stuff will not apply to your XR4100 machine, which has an LS-built engine with a Delphi based injection/exhaust system. It's predecessor, the XR4040 and XR4046, used Shibaura-built engines with a completely different system on them...they used the same diagnostic tool as Caterpillar, from what I've been told. I've had the same experience as you with the torque app and a cheap OBD reader....not much useful info.

Did some more digging. The service manual confirms that this is the hardware needed, and I have requested info from the seller about software. Does it come with the software? Is a dealer registration required to activate it? Hopefully I get a reply.

Interesting thread, curious to see where this goes!

I own the XR4040C . It has the cat unkey plug , you can buy an adapter to convert to obd type plug ...this is what I use to check and reset trouble codes on my tractor

Thanks for reviving this thread. I forgot to update it. Last month I received this bundle of wondrous ECU tinkering tools in hopes to one day do some "tuning" on my tractor.



The fact that the XR4155 has the same exact engine and everything, but 38% more horsepower, is something I just can't get past. I'm going to get that extra 15hp one way or another. But before I get there, I have a lot of learning to do. And a warranty. I have a 2007 ford focus I'll be experimenting on. If I brick that ECU I can easily get another one from a junkyard. A few years of brain surgery on cheap cars and maybe by the time my warranty expires, I'll have the balls to crack the tractor's skull open.

Strantor,

If you don’t mind telling where did you source the diagnostic system? I tried through a couple of sources and batted 0.00

Strantor,

I got it from eBay out of China. It's called Kess and Ktag and you probably shouldn't think of it as a diagnostic tool. It does have some diagnostic features but this system is mainly used for extracting and re-mapping (flashing) the chips in ECUs. I would strongly encourage you to do your own research and decide if you think it will work for what you have and do what you want. As far as hardware goes, it comes with every interface board and cable and jumper and pin and whatever needed to interface with any ECU on the market, from motorcycles to boats to dozers to minivans, but software support has to be written for each vehicle. I arrived at the conclusion that this system would work after extensive research and lengthy reading on Russian/Chinese ECU hacking forums. There is no software support explicitly for the LS XR tractor that I could find evidence of, but they do have the Case IH Farmall 40C in the database, which should be the exact same as my LS XR4140. Same engine, same ECU, same tractor, different color. So in my mind it was a relatively safe gamble. I haven't tested it yet. I just unboxed it to take the picture. I will update this thread once I do.

If you want the legit interface that LS uses, it's called Carnics UVIM. I can only find that for sale from a single seller on Alibaba out of Korea, who has not replied to any of my messages and seems to have not logged in in months. Maybe he was "offed" by the Korean mafia at the behest of LS. And even if he were reachable, the listing does not include software. I cannot find the software anywhere. It's available for download at the LS Korea website if you have dealer login credentials but I don't. Since the Case IH tractor is the same and the New Holland Boomer 40 is the same, either of those softwares should work (I assume) but those are equally well guarded, albeit with more interest and more avenues to acquire them. The pirated New Holland software is available on eBay but I refuse to purchase it and I recommend the same.
