Give this a try
If your system is a Lippert (LCI) and the two lower buttons on the left side of the control panel are ENTER and RETRACT, push them both at the same time. That resets the controller and cancels the error message.
We have this error message intermittently, and the dealer finally broke down and gave us the secret code. SSSSHHHHHH- don't tell anybody!
