I have had this same issue on my '13 F800GS. What I noticed is that even though the light comes on for the ASC, it would still function until I held the switch down again. Turns out to be a real PITA when you are trying to turn ABS and ASC off in a timely fashion. Then you go to do a nice sideways dirt drift and the damn thing cuts power!
Glad to see there is a recall. I will check with my dealer once they get around to fixing my deer-damaged bike and my 600 mile service.
