Hello,
I have a JD 7710 auto power from 2003, couple days ago I parked the tractor, left it there for about 4 days, when I started the tractor again a transmission light came on and impossible to move the tractor. The symptoms are a transmission light alone flashing and a tractor which stays park (won’t move at all) but once the tractor is running the dashboard is displaying N (neutral). After a lot of research and work i ended up changing the ending CAN bus or whatever you call it, there is 2, one next to the APC/UIC unit and one on the back of the seat, but nothing changed. I also found that the supply voltage was low. After a changement of the batteries the voltage was good (with the tractor off or on) but my problem is still here. The codes that i have are UIC 195, UIC 015 and APC 195 it seems to indicate that the two unit are not connected and don’t exchange information. Also something that make me think its the APC unit, is that when I’m looking for the error code in Diag mode you can’t find APC until you plug in the f39 and f40 fuze. The oil pressure seems good tho. Should I send the unit on a check ?
I would be really glad if someone could help me with this problem.
thank you guys.
