Could you post a photo of the connectors for autosteer, they are under the passenger seat at your left window.
There are posts both on case and other CNH tractors. This is one! Case IH Puma 230, autosteer ready
Connectors look like the analog system as the Puma fivefinnishfarmers did AOG for.

Just tidied up from someone else’s notes on here, and added my own bits about relays etc, from @FiveFinnishFarmers I think
Thanks, very helpful
Hi,
You don’t cut wire 3168?
Cable 3168 is so that the valve relays have power, I seem to remember, I cut it and gave it power so that when the button on the rear column is activated the right and left valves work
Which pins would go to a Danfoss valve from the DRC22-40P plug?
Hello I’m trying my first test on an NH T7 245, When i enable the autosteer in console button it appears this on intelliview IV screens, but the steering doesnt work. Is there any trick ? Thank you.
Im trying project 1 with arduino board , same it is working on a CASE tractor quite simmilar.
Finally It works !!! I will explain how to:
The tractor is New Holland T7.245 with autocommand with Screen Intelliview iV.
Connect aurduino to Can connector green behind the seat. can-H Pin H, can L pin J
First, configure HH menus Ch1 yes, and Ch2 yes , Ch1 is for CustomSteer ( rotate fast) second for autosteering.
With motor off :
-
Press this button 2 seconds ( button for engage autosteer on console)
-
Will appear options on small screen in front of steering wheel , select (pressing again auto button) option NAV ( NAU)
3.With nav selected, press again 2 seconds auto button for recording.
Now on intelliview screen will appear option Auto (when you press the console button at the right, to switch off the road mode)
And that’s all!!

Andy, I marked up your diagram to how I wired it, I think there was some confusion with the five farmer notes as they used the DRC22 40 connector on the ag open box. This is how to wire if you are going from the ampseal to CNH DRC22 40 factory plug. I supplied the 6/2 valve from the other connector as the factory steer enable switch switches this supply.

I am trying to copy this on a T7.245AC.
I eventually managed to find Ch1 and Ch2 and set them on and to callibrate the WAS and Spool.
But I am stuck. Pressing the autosteer button doesnt give me “NAV” or anything on the dasboard and no steering logo on the Intelliview IV. The tractor is in field mode.
Am I missing a step?
Which autosteer button? “NAV” where? Why is the intelliview involved, are you trying to steer with it?
Recently I have tried same procedure with CASE cvx, it was autosteer ready ( theoretically) , but i didnt found the Nav option in the HH menu, so , my conclusion is that yes, it has electrovalves, i can see them, but, something was missing, may be control ecu. So this can be your case, but not sure. We are contacting with the dealer to verify the status of this tractor. If i get some interesting info i will post you.
It is the NH autosteer button on the RHS of the cab (actually a three position rocker switch, centre biased).
“NAV” should show on the centre console in front of you. Getting this setting right seems to be an essential precondition for the tractor to accept third party CAN steering commands such as from AgOpen. Certainly it is not taking any notice at the moment (but that could be for any number of reasons …)!
Thank you @FTyuste1234 I will be interested to hear any insights you may gain please.
I had assumed that a 2020 tractor would be CAN steer ready. Do we know when the cut off is?
The previous owner had steered it with Intellisteer but he swapped the kit to his new tractor, so I don’t think I am missing any activations.

hi on a case puma cvx 200 i can find the was and the ch1 for calibrating the was and unlock the auto guidance in the HH menu. if anybody had a discreption or a sulotion thanks.
