CanBus for Beginners - Super Simple

Okay that looks like the right one.


Steer bus is on these wk-bus wires. This Valtra Q has the 3. party unlock and it works. Steer button is not working so its probably in some other can.

Have you made your claas work now?

I tried to bridge as per this drawing, but the problem seems still the same, the PVED will disconnect after couple of minutes, the valve ID is 0CAC1B13. So what I should change in PVED, change the vavle address and just make it different with original address? Does this solution work for all Claas including OSI equipped?

Yes this all works on OSI tractors. You need to connect the teensy to laptop with usb and use a serial terminal to enter teensy into service mode and program the pved parameters and then commit them to memory and then restart the pved and it should all work

Thanks, so I only need to change the valve address to another different one, that’s all? How about the notes from Ryan, should I change the Parameter 64007? Thanks for your help

***(When Changing Claas Parameter 64007) ***
//Parameter 64007(external set point generator address, AKA GPS)
//needs to be changed to 30 (dec) from 27 (dec) then commited to memory. Power to PEVD-CL must then be cycled
//before PVED will send/receive AOG teensy AD,AC messages.

I wrote those notes when we came up with this for claas tractors. Yes you have to change that parameter. It is done in the serial monitor connected to teensy as I said above. The teensy will change the parameter from the selections you make, you also need to set the gps options in serial monitor too.

A quick picture that might be of interest to some is the @Raycorp canbus pcb.
Its really neat and compact and easier to hide

Have you got a link to the connectors required to connect to the atp module, the 6 pin and 16 pin
Searching on the connector database minimum order is 50 plugs🫣

No, I revised the wires

How did you do it, any pictures

Has anyone already tried on a new valtra n5 ? There is a X7C connector but i don’t know if it s working by this way ?

I got these off Farnell I think, no minimum order.
