Question:

I Have a 2015 keystone cougar with 3.0 auto leveling system. It shows an error code check wiring. Can enter to clear the code and it will start beeping and shows code again. I have replaced the wiring harness. It still shows the same code and beeps constantly. I have unplugged it from the panel to stop the beeping. What should I check or replace next? The panel or the main circuit board thing? Any suggestions. Thanks.

We spoken with Lippert in the past about this and they told us that the Comm Error you are experiencing means the controller and touch pad can't communicate. This is normally due to a wiring connection but if your harness is new and the connections are all good you'd need a module # LC304136.
