I have an issue with code 19. Possible cause:
-Unexpected failure of controller software
-Open or short circuit on communication lines
-short circuit to baterry positive on communication lines
I eliminated the controller because I exchanged for another one. I looked for possible damage to the wires, but found nothing. Maybe someone had a similar problem or tell me where to start look.
