If you severed the blue wire of your brake controller and with the controller turned up all the way and with the manual lever fully slid you are still only seeing 4 volts with the e2 error then it would seem that the controller is broken.
The Hopkins brake controller are kind of notorious for being easy to break. For a brake controller I would recommend the Prodigy P2 Brake Controller part # 90885. This is our best selling brake controller because of how well it works and how easy it is to setup.
I attached an FAQ on troubleshooting brake controller installs as well as a video on testing them.
