CanBus for Beginners - Super Simple

[BGunics]

Neighbour has a Deutz Fahr 7250 warrior tractor.
Built-in iMonitor that’s basically a Topcon monitor.
As far as I can tell the ISOBUS parts are unlocked, but no RTK or whatsoever.
Tried to sniff the CAN to see if any messages resemble any other brand but I’m either not on the right CAN bus or it’s indeed totally different. (Maybe the steering is not even via CAN?))

I did collect some data that I attach for anyone interested:

I did this from the standard diagnostic port located on the right side of the CAB.

Here was someone who did steer a new Deutz via CAN. Maybe he can help!

CanBus for Beginners - Super Simple

So first of all big Thanks to @CommonRail for helping me out I managed to get a Deutz with pre installed Danfoss Valve to work with agopengps. This Deutz has a connector under the right console where all Can Bus are accessible, makes it easier to find the right one. The bus is for steering etc is called AutoG. [Deutz Canbus Steering with Agopengps] We got it working after a while, but the main Problem that we had, we weren’t driving so the Tractor would not steer …

Hi! Did you how which connector used on the tractor ? DIg or ISOBUS?

Some Valtra progress for a while. Did some digging for the headland controls both for older Versu T4 and the new SmartTouch T4 (T5 probably works the same).

I’ll try and add those to the code this week after some testing.

[andyinv]

I still couldn’t find valve bus on latest model Valtra, but I think it’s because needs 3rd-party steering unlock.

[nut]

Yeah the smarttouch is tougher to crack, you probably need the unlock. Pre-smarttouch uses PVED-CLS but we tried to control valve directly on fast steer smart touch but no luck. Valve is OSPE but actuator is not PVED-CLS, has dual 4-pin Deutsch. My guess is some proprietary version of PVED-CL. Don’t have manuals for smarttouch, only older T4 Versu/Direct.

Gave this Deutz 7250 TTV another chance this afternoon.
While fiddling with the CAN cables I managed to get a PVED ALARM error out
SPN: 520192 FMI: 13
So I guess there’s indeed a PVED there.
I was able to read the wheel angle using Brand = 1 in Tonys CAN code.
The PGN for that is: 0x0CAC1C13

However the factory engage buttons don’t seem to be appear on any of the CAN buses.
I did sniff the CAN buses for anyone interested

Maybe the factory Agrosky iTerminal (running Topcon) is the curlprit? (it has no GPS installed )

[BrianP]

I’m steering a 6185 TTV over canbus with an AIO 4.1 board.
The armrest buttons aren’t activated without the factory fitted receiver.
You must have easysteer engaged for auto to work.

[BGunics]

Oh, I need to check how to engage that easysteer. I’ve not seen any button/knob for it.

And I notice you use the other 2 pins. (I’ve seen WAS reading on 2 of the CAN buses as well.)

[BrianP]

The one that looks like a steering wheel next to autosteer.

@CommonRail I have tried two New Holland from 2018 and 2020. they should both have CANBUS orbitrol.

i have tried with a canbus sniffer, but i am not able to find either the ID number for the Joystick activation or the valve (H and J) Behind the seat.

is there something in the HH menus you need to activate before it works? it seams like the valve and joystick is offline (standby)

any help appriciated.

[CommonRail]

First take a photo of the steering valve so we can see if it a CANBUS type.

HH menu you should be able to turn on the steering wheel options (valve and nav controller) and also calibrate the wheel angle sensor and valve.

Once that is done then try again with AOG.

[del_boy]

If you go into the H Menu, you need to go to U1 → H3 → Steering controller (same icon as gps switch).

When you select the steering controller, "ch_ _ "will appear in the lower display, scroll across to “ch2” and wait a few seconds, it will then change to say “NO.” Scroll across once more and it will change to “YES.” Then hold the minute button (the one you’re scrolling with) for a few seconds and the dash will beep to save the value.

[Steerguide]

let me take a picture later today - @CommonRail

@del_boy do both CH1 and CH2 need to say yes ?

do i need to do something in the intelliveiw terminal?

the joystick activation button - does not say a bip when i press the button.
older non steerReady new holland, they all say bip in that autosteering button.
seams like the valve and joystick is “offline” even with ch1 and ch2 (yes)

Read my CVX175 thread.

Hi Tony @CommonRail. I have your teensy pcb and I would like to put the bno in RVC mode. Do I have to modify something?

[CommonRail]

I think:

• remove the two pins SCL and SDA from BNO to the pcb
• connect wire from BNO SDA to Teensy RX5
• solder ps0 on the bottom side of BNO

[Nacho]

Thank you so much

[pniels]

Is it a big advantage to get the RVC mode, also run with your pcb on the Fendt 828 scr, and do you have a picture of the modification?

[torriem]

Could also put a bodge wire on the back of the PCB from the pin that P0 plugs into to the pin that Vin plugs into (connect P0 to 3.3v). That way even if you plug in a new BNO it will go into RVC without needing any modifications to it.
