2014 410K Flashing monitor

[GregA]

My 410K TC is having the same kinda of problem. Won't even let me start it, went through the service menu and the Seat sensor says Error. Do i assume that it's need to be replaced?
Serial Number is 1T0410TKLCE228167
Attached is a picture of the lights that are flashing except for the battery. At first I thought it was the battery were dead but they are up to 13.4 volts now, and only couple months old. Not sure where to start here, There is no Codes coming up in the service menu.

Someone also posted that with no engine hours showing, its got no communication from the ECU, where do I start?
I might have a mechanical contractor that has JD service advisor come out, but if I can get it myself, can save some serious cash.

First, on the left side of the engine mounted on top of the frame, with a rubber cover, is the F4 fuse. Check to make sure those connections are tight and that you have voltage at both posts with a voltmeter.

We just checked and we have 12 volts each side.

I think our next step is to make sure there's power to the ECU. If so then it might have to be replaced? We have no communication through JD link.

We jump the start wire to the ecu and engine starts, just no lights controls or anything. That rules out the ECU being faulty, We are now making sure the VCU has power to the pins needed. Checking chassis ground also and it was dirty so clean that up. Will keep everyone posted on what's going on, if anyone has suggestions let me know.

Well we figured it out, just putting this here in case someone else has the same issue. We followed the Diagnostic Manual and found the Can bus was not communicating, and indicated a short. We finally checked by unplugging modules to find out which one it can be. To our surprise, once we unplugged the Telematics module located near the battery box on the left side, everything powered right up. This is safe to assume that the module box is defective or a short in the harness leading to it. But i have no plans on keeping the telematics hooked up as we do no use it or subscribed to John Deere's wireless GPS and Communication software.
I'm hoping I can help anyone else that might have these problems also.
