Diagnostic adaptor for OBD2

   / Diagnostic adaptor for OBD2 #21  
It has been too cold to investigate. I did call TS performance as well as EFI Live to see if either of their programmers support Kioti/Daedong/Doosan (as I suspect the entire engine family of t3 and 4 cylinders is common to all). I need to plow, but I cannot really see anything with the hood and loader in the way.

RickB's perspective that it would be hard to deny my warranty is a good point. I believe Kioti had a four year warranty in 2014. Kioti, not in writing, but over the phone told me I voided the warranty. The backstory is this.

I contacted my selling dealer about my tractor skipping out of range in October of 2015. My dealer contacted Kioti of America who informed my dealer that I had voided the warranty. I called the warranty person at Kioti and asked why was my entire warranty voided and, Tim Fox, the American Importer warranty guy, said:

1) I had worked on my own tractor.
2) I had modified my tractor.
3) I had abused my tractor.

Huh?

1) Tractors are tool carriers. I added my own third function because my dealer, at the time, didn't know how. I didn't modify any electrical system on the tractor and my third function looks like it came from the factory.

2) I was sold on the premise that the tractor would regenerate on average every 50 hours. My tractor was regenerating every 8-12 hours because it was always running rich because it wasn't warming up. This same problem struck the entire diesel industry with Tier IV diesel engines and the field repair among technicians was and is to install a warmer thermostat. As measured, the stock thermostat begins opening at 165 degrees F and is fully open at 180 degrees F. After carefully measuring everything, I installed a thermostat that begins opening at 175 degrees F and is fully open at 185 degrees F and also featured a bypass for high rpm operation as the stock thermostat. This meant that my tractor when not under a load wouldn't cool down enough to go back onto the rich warm-up fuel map and the DPF wouldn't load up as fast as it had been. My T-stat swap effectively solved my problem while also maintaining the factory fuel map as at every temperature, the engine runs on the factory fuel requirements and now my tractor is regenerating at a far more tolerable 25-35 hours.

3) When I specifically asked how I had abused my tractor, Tim Fox, the warranty guy refused to offer any explanation or example leaving me to wonder what the definition of "abuse" he used.

Meanwhile, one dealer told me that they sold five Kioti tractors and all of the customers had mentioned my videos and the Russian importer of Kioti has asked for permission to translate and use my cold weather starting video.
The EPA mandates a 5 year warranty on components related to fuel emission standards. Most certainly covers anything that controls, pumps, or injects fuel. Separate and beyond the manufacturers standard warranty. This warranty is industry wide and does have an hours of use limitation.

I'm just over 500 hours. I cannot find Kioti's statement but Deere is 3,000 hours or five years from time into service.

Kioti's is 5 years unlimited hours for private use, and 5 years 3000 hours for commercial use.

When I start hearing that dealers are voiding warranties because we work on our own tractors, I start thinking about stripping all the electronics and emissions crap off the engine and running an aftermarket engine management program. It would be a time consuming effort but oh so satisfying....

If you modify anything or break something you can't expect them to warranty it.
The warranty is for factory defects, not for owner mistakes.
Just be careful when working on it. If you think you have a warrantable condition verify it with the dealership and let them repair it.

I added a third function, undercarriage armor. I didn't ask them to warranty my third function or undercarriage armor, I asked them to honor their warranty.

His transmission is skipping out of range, that sounds like it could be a warranty issue to me.

Yes, I strongly suspect the shift fork is bent from somebody attempting to forcibly put the tractor in gear when the gear were not lined up as the problem never happened when I "rattle" the gates once in gear but will happen if the shifter is put in gear and the shifter isn't lightly rattled. The tractor had 7 hours on it when I took delivery and the problem has been there since day one.

Anybody happen to know what diagnostic adaptor Kioti uses on their NXs? I have a bad injector and want to see if the computer happens to know which one using a Launch Pro Touch.

FWIW, the connector on the tractor looks like a Molex 33472-1201 MX150 12-Pin, female, without the two notch tabs on the outer connector.

Hello MinnesotaEric ... did you ever get your Launch Pro Touch working on your Kioti Tractor?
(I realize these posts were years back)

Funny you ask as I just got a new Launch 431 with every adaptor possible but everything came to a grinding halt because I need to first set up an account to fire it up.

The short answer is not yet.

OK ... would like to hear of any success you have...

Cheers!

So it is a no-go for having the correct adaptor. It would be nice if somebody could identify the diagnostic plug Kioti uses. I suspect it is a Delphi engine management system since it uses Delphi injectors.

I think this is a KUM PB625-12027 12-pin plug (Korean mfr) and here is an eBay listing for the F/M pair "KUM 090 Series 12 pins Male Female Waterproof Connector PB625-12027 PB621-12020"(Pardon Our Interruption...). If you Google those part numbers you will find more examples.

I believe the NS and NX series tractors use FT4Scan (password protected) with the Doosan (Bobcat) uVIM. The software for knockoff uVIMs won't have Kioti tractor models but they have a Tier 4 engine selection. Just a thought.

Thanks, I had forgotten about this. The password protection is what prevents communication. Not being a programmer, the password protection has stopped me from pursuing getting the FT4Scan software and the adaptor cable needed to communication with a PC laptop.

All to say, you just reminded me of this thread here on TractorByNet.

Eric, will the Right-To-Repairs law help you out in obtaining the correct software to read your NX EMC?

It would, but I don't have a local dealer to speak to about this.

That plug a few posts back is for the transmission control unit, not engine.

As for checking your HP common rail fuel injectors the best test you can do is a backflow test on them. Unhook the injector return hoses, pinch off the injector return line towards the front of the engine and hook up an array of bottles with hoses going to the injector returns (like see in in picture). btw you should not need to use the injector return hose clamps for this test. Start & run engine for 5 minutes with bottles attached. Watch bottles. If you get over 30 ml in 5 minutes on any bottle you have a bad or clogged injector. All injectors should flow the same amount of fuel if one is out of whack you will know it.

I've done this test with water bottles and they instantly would fill, due to clogged injectors.
