I have a JD 2630 that is running a JD 1910 air cart, JD 2000 rate controller and JD blockage monitor. I also have a JD atu 100 auto steer unit plugged in. It’s worked well for the past 2 years but recently I keep getting steer & controller errors. Seems like if I unhook the blockage monitor (last thing plugged inline) then it works. But if I bypass the rate controller and plug the blockage directly into the 1910 cart plug it works fine as well. Any ideas to try next? Thanks.
