A John Deere tractor is a single unit of equipment that can be used on a farm, a big piece of land, or a yard. Even though they’re good, you might sometimes find yourself looking at John Deere / ECU numbers. It’s not a big deal because Raven’s equipment also has diagnostic trouble numbers.
When a problem is found in a circuit and more than one part of that circuit isn’t working right, a trouble code will be shown. The fault number will be shown, which will help figure out what’s wrong. It can be hard to read all the codes in your user manual if you are having trouble.
So, you’ll be able to look at our list of John Deere / ECU trouble codes and figure out what’s wrong before calling a John Deere dealer for repair.
