Hello colleagues. Can anyone tell me what exactly the KUBOTA K-OBD ACE diagnostic kit includes? These are the numbers I find: 07916-81100-changed with: 07916-81102-changed with: 07916-81103, but there is no information anywhere about what exactly is inside (what cables, software, hardware). Best regards

designed to help farmers / fleets that run and repair our equipment.
Not cost effective or realistic for a single unit owner IMHO. Costs a couple thousand dollars. You can buy with or without laptop, etc... so you customize the parts and pieces you need based on what equipment you are operating. For example construction equipment and Ag. equipment can use different cables and plugs. Your dealer should be able to tell you what bits and pieces will be needed for your fleet of equipment. I have seen a page of options of add ons and do dads avaliable.
Its lets us read codes, make resets and diagnose problems. Helps diagnose and repair.
What it doesn't do is let you into the ECU to change programed parameters calibratetions like shutting off sensors, doing DPF deletes, change max rpm's, injector settings, etc...

Thanks for the answers, but my question is what is hidden behind these numbers, what is in the briefcase? I am engaged in the repair and maintenance of agricultural equipment (Kubota) and have worked with this diagnostic and am aware of its functions. Now I want to purchase my own.

What it should be is a USB-A plug and a universal phone app for $100. This stuff is stupidly expensive for no good reason. Farmers used to be able to fix their own tractors which is why there are antiques at parades, but with computers that lock owners out of repairs modern equipment becoming "antiques" is coming to an end.

Absolutely.

To your exact point - I have a BMW scan tool app for my phone. Its a partial port of the OEM diagnostic and coding software used by the dealers. BMW has made the code and vehicle data files public. The only thing private is the vehicle factory security modules that let you do things like change a VIN. If I wanted to I could build a laptop with the same functionality as the ones dealer techs have.

So this is strictly on Kubota and other OEMs that are holding equipment owners hostage for no reason other than greedy profits.

Contact a dealer for a definitive answer. My understanding is based on a previous thread involving @whitetiger.

First and foremost Kubota has to approve your "need" for the software and you have to attend a multi-day factory training class in AZ before you can actually buy the software and hardware.

The software is divided into separately licensed packages for agricultural and undustrial machines. You will get pretty much everything the dealer techs have.

The software requires a yearly license for which you pay an annual 4 figure license fee. You also have to attand a yearly refresher training class in AZ.

Maybe whitetiger can weigh in and correct any inaccuracies or ommisions in my response.

Hope this helps.

Kubota is just following John Deere and not allowing 'right to repair', which I thought went to court and Deere lost.
For Kubota it's a HUGE money maker. There is no good reason why owners can't have access to the 'computer' to reset 'codes' or look at sensor outputs.
It's been posted here ,that changing an injector requires a $$$$$$$ trip to the dealer to 'program the computer'. Rediculous. That simple task should be done by the owner. Actually the 'computer' should just read the sensor and automatically update it's firmware.Less than 30 lines of code for that operation

gotcha.... from what the kids tell me but this is from the top of their heads. They suggest you ask the people selling these products (OEM or aftermarket supplier) whats in the boxes as the aftermarket suppliers may be different than an OEM supplier.

81100 is the license which gets you access to the Kubota website, login ID, software and passwords
81103 are the plugs, cables, vehicle communicator interface for Ag. equipment using canbus in a small packout style briefcase.
90014 for non canbus users these are the serial connectors and cable including a vehicle communicator interface in a small packout suitcase.

this is all they had on hand but for sure your supplier of choice will be able to tell you.

It would be really nice to have a 3rd party service provider with reasonabke rates near me :)

The thing is, even the official dealer in my country doesn't give me any information. I have completed courses and certificates for service activities and handling computer diagnostics and believe me, not everyone can handle it, you need to understand what exactly you are doing. Calibrations, ignition corrections, entering injector codes, programming computers and many other options are done. That's why I think that only trained personnel should handle it (my opinion). And modern tractors are self-diagnosed via the CAN bus so that if there is a real problem, they display an error code on the dashboard, which can orient the operator where exactly the problem is and try to fix it.

Maybe time to reverse engineer their interface and messages and publish the results as an open source project ;)
Lots of people have tried that with other OEMs and with limited success. The interfaces are pretty standard.

But capturing and reverse engineering the traffic on a CAN buss is daunting. Add to that some OEMs are encrypting the data making it nearly impossible without the proper keys.

I think the real solution is regulatory requirements but big money lobbys are hard at work to prevent it.

I am afraid Dan, you are 100% correct in all points.

Especially the encryption is a huge hurdle.

Nevertheless somebody that has access to the Kubota system should be able to accomplish that. Possibly legislation will take care of that when the people will govern their countries again instead of large corporations through their lobbyists.

But this is something people with newer tractors and cars have to worry about, for exactly those reasons all the vehicles I will drive until the end of my life I own already and none of them was built after 1991.

Thats the Readers Digest version of the OEM talking points..

My response is its my machine and my money. If I want to risk screwing it up that should be my choice.

Most OEMs sell "reasonably priced" tools and licenses via third parties. Kubota is not in that group.

I wish you luck dealing with the Great Orange Wall.
