Engine Error code P0563

[mjhartmann08]

Hi All,
Just took delivery of my L6060HSTC. It has an engine error code P0563. From the information I'm able to gather, it's related to voltage, but I cannot determine of it's hurting anything. Looking to the forum for any help.
Thanks.

Here is the page from the L series code manual.

I am not a DTC expert. Sheepfarmer is the one! There are others as well like Whitetiger, Lugbolt...............

If you have a volt meter, I would measure voltage across the battery terminals with the engine running.

The system has seen 16+ volts which is very high. Look for any wires not securely plugged into the alternator which could feed the charging system erroneous signals on the state of the battery charge..

Note on the attached page that there is a "Limp Home Mode," which is how the designers intended the tractor to operate with reduced performance for a short time when this specific error code is thrown.

This is different than say a low oil pressure condition where the engine would be stopped or serious damage would happen immediately.

Another member with a different L series posted a page on resetting the computer. See if it makes any sense when looking at your machine and its various buttons.

The Code page has a line Recovery from Error which in this case is Key switch Off. This could mean once the error is corrected the code will go away just by turning the Key to OFF.

Dave, thank you. I posted another thread about a wire harness left of the seat. I wonder if that could be related.

The seat could be monitoring your heart rate through the pulse on your butt and if it thinks your heart has stopped ( because of disconnected wire) it might try and revive you by raising tractor electrical voltage

Seriously, if this is a new tractor with error codes and disconnected wires I would be insisting the dealer make a house call.

When the code is fixed please report back as it helps every one learn.

A high voltage typically means a "ground" wire or return circuit is not connected well.
An alternator is trying to over come the poor connection thus bumping up the voltage.

As Dave pointed out - The dealer should deal with this rather than you trying to find the problem. A battery that is getting a high voltage will have the acid boiled out over time and you will need to replace that soon too!

it's inconvenient to have a new tractor go right back to the dealer, but on these newer confuserized tractors, the longer you put something off the more serious the issue gets. It's even more inconvenient when it finally dies in the middle of hay season, or right in the middle of doing what you need to do with the tractor at that time.
