NH 8670 diagnosis

[Bryson H]

I'm working on a Ford New Holland 8670, replaced brake seals on the left side, replaced a few hydraulic lines and a new radio. After that was done it threw the code 4356 and 1096. 4356 – EHR FB 3 Shorted to low source Cause: Sensor feedback voltage was less than 0.25 V. I cannot locate this sensor, nor do I know where the wiring runs for it so I can check for a rubbed or pinched wire. 1096 is a DTC err that also just showed up. Also wont allow me to use the 3pt hitch and cant figure out why, it shows up on the dash that the 3pt hitch in inoperable, If anyone knows where to start looking it would be great, thank you!

Sounds like a problem with the harness for remote 3.

From ChatGPT -

What the code means​

• The “EHR FB 3 Low Err (4356)” is an error relating to the rear remote control / electro-hydraulic (EHR) system, specifically Remote No. 3. Wiring Diagrams+2canbusemulator.com+2
• “FB 3” generally means “feedback channel 3” (i.e. the sensor or circuit for remote #3). The “Low Err” part suggests the feedback signal is too low (or perhaps open / not reaching minimum expected voltage) for that channel. Wiring Diagrams+2millersellner.com+2
• The fault code list shows “4356 EHR FB 3 Low Err,” and “4355 EHR FB 3 High Err” as complementary possibilities. millersellner.com+1

So, in short: the tractor is detecting a fault with the hydraulic feedback or position sensor on the third remote (valve) circuit.

Hello Bryson, welcome to YT! Unfortunately I can’t help you with your problem other than suggesting to check for pinched wires. Secondly, I might suggest a battery disconnect as a reboot to the system if you didn’t have them disconnected during your repair. Without looking at the parts diagrams I would suspect that these machines have wet brakes so the repair you did was fairly extensive requiring removal of the wheel and axle etc. Do you have a service manual for your tractor? If not I would strongly suggest acquiring one, analyzing the faults for code repair solutions is a daunting task without one. Since YT sells manuals I normally steer folks towards their options but in this case they don’t seem to have a listing. The YT parent company ASAP, probably does but I didn’t see anything come up from them in a web search. I’ll just recommend going to Farm Manuals Fast, it looks like they currently have a download available for $40. The best of luck to you.

Got rid of the code but now it's showing with "area 1096" which doesn't indicate much and yes i do have the OM for it and there isn't much information on what codes mean but it doesn't have "area 1096" any clue as to what that indicates?

I am not suggesting the info you are looking for is in the “operating manual” I am talking about the “service or repair” manual. That manual is offered by the above as a downloadable PDF. Used paper copies look to start at $180.

Okay I understand what your saying, thank you

I don’t remember the code, but when my 8970 had pto troubles, a corn cob got in behind a thin shiny vertical control rod above and to the right of the pto on the rear axle/ trans. It busted something slightly on that thin rod - wire really.

Seems like a vulnerable spot.

The 1096 DTC error in Ford New Holland tractors indicates a problem with the tractor's remote control system. This error is often related to the hydraulic feedback or position sensor on the third remote circuit. To troubleshoot this error, you should:

• Check the wiring and connections for any defects, such as loose, corroded, or damaged wiring and connectors.
• Inspect the sensors within the remote control system for any faults.
• If necessary, replace the ECM (Electronic Control Module) if it is faulty or damaged.
• Clear the error DTC code to reset the system.

No codes are present anymore, now facing the issue of the 3pt hitch not working, the blinking light on the right control panel indicates that the hitch is disabled, I'm using my OM to do as it says for "EIC programming" but can't seem to figure it out and get the hitch enabled. Also does anyone know where to find the remote no.3 position sensor?

 

[Bryson H]

So, I had fault code: f024 and f418, F418 was just coolant level, F024 was for the 3pt hitch needing calibrated. I calibrated the 3pt hitch and it started working again, but every time the machine is turned off then back on it has the hitch disabled symbol, and the warning light stays steady instead of blinking like it's supposed to when there's a fault with it. Anyone know how to make the machine not disable the 3pt upon start up?

 

[trackrat]

Can't help you with this problem but with my history with new holland tractors you probably would not want my help

Did you ever attempt to purchase/download the repair manual?

 

[Bryson H]

Did you ever attempt to purchase/download the repair manual?

No, I'm not really wanting to purchase the repair manual for $40

Not to be unkind but it sounds like you only care about repairing if you can get help for free. If it is not worth $40 to get the manual then maybe you should just sell the tractor.

Maybe he doesn't own it. Maybe he's doing it as a favor for a friend or neighbor. Maybe he is going to sell it and not wanting to spend more money than necessary. Regardless, it could probably be downloaded for free somewhere.

Looks like these tractors sell for somewhere in the $25 - $60,000 dollar range. If I could spend $40 for the manual and an hour or two reading it and figuring out how to fix the problem that returns it to a properly functioning asset, I know what I would do. If you’re fixing it for someone else then the $40 would be added to their bill. Looking for free manuals has at least twice got me nothing more than a download of viruses.

And that's how you would go about it. So what about what you/we/us would do... I have a manual for nearly everything I own, whether paper or free download. But there's nothing wrong with joining a tractor forum and asking tractor questions. From his other thread he may have gotten his issues resolved. Acting like a bunch of elitists isn't helpful...

I was just laying out how I see cost effectiveness, call it an elitist action if you want. These newer tractors have a lot of complex systems on them especially those with electronically operated hydraulics. I am sure your know the best way to get an understanding of the system and how to repair it is to read the manual written by the builders of the systems. You are right there is nothing wrong with joining a forum to seek guidance,

 

[Bryson H]

got er fixed and out of here! I swapped the hoses around on the quick connections on the rear of the machine to where instead of lifting the loader it would lift the grapple. After this I swapped the hoses back and the loader and grapple work as should. I figure one of the lines was blocked or the quick connect wasn't seated correctly. Thank you, guys, for your input!

I fully see where your coming from... I was just trying to see if I could do it without spending the $40, while it's not a lot of money, I don't want to buy something that isn't necessary... All in all, I'm over $2k into fixing this thing and had the left rear axle off to do brake seals (took a month and a half to get the seals just for one of them to be the wrong seal) fix the grapple, 3pt hitch, radio blowing the KAM 5A fuse and many other small electrical issues. Mind you this machine is NOT my tractor and only had the OM for the machine and loader which did help, but only at base level.
