ER is not one of the display messages covered by the troubleshooting chart in the instructions for the Primus # TK90160 which I have linked to the right for you. Because you are seeing ER that is a good indication that there is a major internal problem and the controller will need to be replaced which is the case with other Tekonsha controllers that display ER. A major error inside the controller could happen if the positive and negative wires were reversed by accident.
