3320 error code 5

[tglass]

this may have already been brung up before, but has anyone had this code come up before? It happens when I hit the cruise control, and after a while with it on, the hyd. (and hydrostatic)go into a very slow mode till the engine is shut off and restarted. As long as I don't hit the cruise it works fine.

Err 05 Brake and Cruise Set/Decel Switch. Cruise control Set/Decel switch depressed while brake is engaged. No cruise function. Release brake pedal; Contact your John Deere dealer.

Straight out of the manual. It sounds like an electrical problem, could there be a plug loose? My dad's 3720 has Err 15 and it was just a corroded wire.

johndeere3720, kind of what I suspected. Now to find the faulty switch or connector. I'm sure it's located at an easy to locate and repair position. Thanks for the help.

If you have the serial number here is a link to the parts catalog which should have the right wiring diagram. :thumbsup: John Deere - Parts Catalog
