Besides the code, any problems?
An old post showed an error 201:http://www.tractorbynet.com/forums/...rating/261595-2008-john-deere-4520-error.html
Possibly 201 instead of 210?

No problems as yet!! It was definately 210.

Funny thing the dealers Service Mgr told me the codes only go up to 77 really does no make sense to me??

Thanx

Here is a page from the service manual. Looks like it could be an engine computer programming problem.
Is the code displayed all the time? Did the engine kill when it came up?

Thanks for the info, I went out and tryed the Tractor and everything seems to run ok. It did not kill the engine when it showed up and when I tried it again the code no longer showed.
