Subject: Another CaseIH 7230 DEF question

Southwest Iowa

We've got a 2014 7230 that we bought new and never had any issues with the DEF system up until this fall. A few weeks ago, I'd get these faults. The red one was always first, then the others show up a few seconds later. My DEF gauge on the Pro 700 disappears and all DEF information under Combine Info goes blank.

The dealership was out 10 days ago and replaced the wiring harness on the back of the machine that has around 10-12 plugs. They go to the sensors in the exhaust, to the pump, etc.. The thought was there was a wire in that loom somewhere shorting out. Well that seemed to be the culprit since the combine ran around 700 acres and those faults never showed up. But now they've returned and popped up twice in the past 200 acres or so.

Just curious if anyone else has seen these faults and what you did to get things working properly again? Deleting would be best, but probably not gonna happen this year.

Thanks for any suggestions or help!
