Thank you. It's our first job with the dozer and it's a little stressful.
Mechanic: JimmyM827, Bobcat specialist  replied 1 year ago

This code stands for Monitor panel CAN communication (Defective communication)

so we have the controller, monitor, and the wires in between that need to be checked, make sure all connectors are clean and not corroded or loose first. Honestly, this points toward a bad controller or monitor unless you find unplugged or broken wires. This is a very expensive controller at almost 3k new. I'm sorry to be the bearer of bad news, and I hope it's just a loose plug or obvious broken wire.

Please respond back if you have any more questions , I will be back online tomorrow from 8am central time. -Jimmy

Just to let you know, we hired a mechanic. He put did a diagnostic on it and its electrical. Hes still working on it, but said it's something simple, definitely not a controller or anything major. Thank you again.
