So if the BCM sees voltage or load that is out of spec for external lighting circuits, it will set the hyperflash condition. This is supposed to indicate to the driver that there is a problem in the circuit and so you will hopefully fix it. I think that one of the resistors had actually gone bad on mine causing the issue.
