Flexi-Coil 5860 air cart task controller and VT continuously disconnecting from Deere 4640 display

Question

I have a JD 9460R with a 4640 display connected to a 2018 Flexi Coil 5860 air cart. The air cart randomly connects and disconnects from the tractor. Cart seems to be getting good power from the tractor, grounds have been cleaned up, issues seems to be in the cart UCM or with the Deere 4640 display. Something is causing grief with the ISOBUS system.

Answer

I have the same problem in my 9510 have not found the solution  as of yet. Told it could be software on the cart or tractor.
 my armrest screen and my 4640 fighting for priority control. No matter  how I had the priority setup in the settings. It just constantly kept passing between the two and then reloading thus turning off my meters

Answer

I believe you are correct. It’s definitely a Deere problem between the gen 3 commandcenter and 4640 deere monitor. When I unplug the gen 3 commandcenter, the cart immediately loads on the 4640 and does not disconnect and works perfect. As soon as I plug in the armrest screen again the cart disconnects and disappears altogether, flexicoil rep had their laptop plugged in and the cart was still online while it was disconnected from the 4640. I have spent hours on the phone with my deere support and it’s definitely not in the settings. Seems like a known “compatibility issue” that hasn’t been rectified yet. I wish Deere would push an update to all of the gen 3 commandcenter screens and fix this problem by giving me an option to completely disable everything but the tractor controls on that screen. There is a checkbox under multiple displays that allows you to run ISO impliments on your commandcenter, and even with that unchecked it seems like it’s still trying to connect at times.

Answer

Fixed! When running multiple displays with a tractor with a GS3 commandcenter. You need to push the implement BUS to your corner post screens (4640 in my case). Make sure you setup your 4640 as the primary monitor and then on the commandcenter go to menu-display-settings-multiple-change settings. Check off implement bus ISO display and make VT number 2 if you want it to run on the corner post display, number 1 makes it run on the commandcenter screen. Hope this helps someone one day.
