Expert Reply:

When your Lippert Ground Control 3.0 # LC358590 has a reading that says "Comm Error" it is referring to the communication between the controller and touch pad. You will need to check your harness to ensure it is connected properly and there is no damage or corrosion. If it all looks good then you'd need a new control module part # LC304136.

You can also check the charge condition of your RV battery and the connections to it.
