Chopper knives message is obviously unrelated. Usually what happens is the lever you move to engage or disengage the knives has bent a bit and isn't close enough to the sensor. You can bend it back. At least this message won't shut down the rotor for you, at least it didn't for us.

As for the other message, It's probably a wire that broken. Check the bundle of wires that goes down the left side of the feederhouse from the combine to plug that goes into the headers. Pull off the plastic loom material and look for wires with worn insulation. Over time the plastic loom will wear into the wires which can cause them to short to each other. that's the first thing to check. You can also go into diagnostics[1] and pull up the voltage for the header height sens and see what it reads. It should be low but not zero without a header on. As you go up and down see what it does. And you can have someone wiggle the harness while watching that.

[1] If I recall you go to diagnostics->settings and select the header height sensor, then switch to the graph tab to see the readout.

 

Does your header height sensing work with any of your headers? That screen looks familiar from previous combines but can't remember exactly when it would appear. Maybe when it doesn't detect HH sensing? Any way it didn't affect anything as it would go away as soon as header was installed and in the field.

 

Messed with the combine again today and can’t get the error code to come back up again. I recalibrated the head (2162 Draper) and now everything appears to work.
I wish I found something so I knew it was fixed vs. a possIhle intermittent electrical problem.

 

Most likely your header recognition wire/voltage was "funky". At 0V, the combine assumes there is no header and does not throw codes. Then there are different voltage levels for different heads starting at about 0.5V. All of your errors can be explained if the" header type" voltage was "floating around"

• The chopper knife error will appear if the combine sees the knives IN on a corn head header select, for instance.
• The "shorted to low source" - if the combine thinks (because of a floating header type voltage) you have a head on you already calibrated - and you don't, it will throw those errors because the sensor input voltages are 0V (no header, no sensors - but the combine thinks there should be....)

My guess is you had moisture in the 31 pin plug, causing false readings on the header recognition wire. You might also have a bad wire on the feeder somewhere shorting to another wire or moisture in one of the other plugs.

You can look at that input under Diagnostics>>Settings Tab>>Group=Header>>Parameter=Header Type Sensor. Hit the Graph tab and read voltage in upper left corner.

• Pin 27 in the combine to header connector (yellow wire)
• Should be 0V with the header disconnected
• Shold be a consistent voltage with any specific head attached - for instance 4.2V is "corn".
• It should not change as you raise & lower the feeder - or wiggle wires

 

Your problem is slightly different given that it did it with header on, but I still have an 8010 and for the last number of years it will give the same error without a head on the unit, but as soon as the 2162 is plugged into the combine the error goes away and will only come up when I unplug it and it has never caused any issues, although it did not used to do it so not sure what changed but as I said causes no problems with auto header height or operation.

 

When unplugged, if you put a jumper wire from pin 27 to pin 13, (Signal ground, light Blue wire) it would be interesting to see if your error went away.

 

I got a 2014 9230 with the common cab on it. Whenever it has a header on and the electrical connector isn’t hooked up like when I’m changing headers it complains that both sensors shorted to ground. I think it’s a software thing. Never actually had any issues once header is hooked up and calibrated.
