Looking at a 8120 combine. Has anyone setup AOG Autosteer on one of these with canbus? Or similar Case IH canbus machine? I have installed 4 AOG autosteer systems with rub wheel. Help appreciated.

I saw @CommonRail has some info on canbus for beginners after I created topic.
In a week I’ll be looking at an 8010 not even sure if it has all the things on CAN but we’ll see
keep us posted.
we’ll have to bypass the entire system… rear WAS is broken and it would cost 4,5k $ to fix it… totally not going to happen when you can get any WAS solution for less than 200$
I don’t know what you want to retrieve on the CAN but the valves of the CNH harvesters of the info I have are not in CAN
Autosteer by AgOpenGPS , and was wondering if there’s an easy. But looks like we’ll just throw in an AIO board and take over the valves ourselves.
8120 doesn’t have valves on can either?
The Trimble NAV II controller can work with valves via CAN or directly control with them via PWM. Which it used depended on the model and the year. My 7240 combine definitely uses CAN to communicate with the valves. But my older combines did not. Currently my 4430 sprayer does not use CAN for the steering valves, but my Magnum 340 does use CAN.
And the wheel angle sensor was the same way. It could use the CAN-based gyro sensor, or a direct analog pot. I’m not sure how to tell the controller which you’ve got, but I know I was told once by a tech that if the internal POT ever failed on a steering cylinder on a combine, you could replace it with a gyro module. I imagine you could even put a new DIY analog WAS on the combine and the NAV II should be able to work with it. But like I say I don’t know how you would configure or calibrate it.

i am in europe i have a new holland CR from 2022 and the valve is not in can the valve is connected to the UCM machine module the nav is only used for the devers. I’m sending you pictures of what I found.

Hi torriem,
We have a 30 and a 40 series Case combines and a 4430 sprayer which I would like to put AOG on. How are you determining if the machine uses CAN or not for the steering and WAS?
All Flagships 40 and 30 series use a trimble nav 2 or 3 located below the cab on the right side. 010 and 120 series combines use a trimble nav 2 or 3 located in the cab on the right hand side mounted on the floor below the armrest. The steering valve is located on the left front underside of the cab, there are 2 control solenoids and one lock solenoid. The easiest way would be to just run wires to the 3 solenoids and pressure sensor and tap into the rear axle angle sensor in the left rear steering cylinder if it was an autoguidance ready machine if there is no nav present.

I’m looking for the CAN address for armrest auto steer engage button on a 2015 Case Maxxum 125, does anyone have access to that info?
At 2015 you might be a bit early on the canbus on them models but worth a look.
Do you have the green canbus socket behind the seat? On the canbus models that will do the was and the steering and the plug on the pillar was used for joystick engage.
You might have to connect to the 40 pin connector otherwise behind the passenger seat
Is it steer ready? Them engage buttons were fitted to them all regardless so it might not actually be used anyway
It’s not auto steer ready, but if I press the button it beeps at me so I thought I could use the button at least…
You might be lucky but usually when the buttons beep like that on cnh it means theyre not active.
Not sure on the addresses for the steer button but maybe if you looked at the canbus code for cnh then find the engage part it might tell you the code
trying to calibrate the was on a puma 165 i get this error code at the end of the calibration, has this ever happened to you? how to fix it?
Would give this a try.

I want to do it, but I need to figure out the address first. Some time I’ll hook a can sniffer up.
Try any of the existing addresses in the code first, you might get lucky.
