.....I recall that you had some other electrical issue with a brake code. What's up with that, although I"m not making any connection between the two as of yet.
Update on P0504 code. Spyder has been at the dealer since Sept 12. Service Manager called and said "you as re not riding enough, the pistons on the brake calipers are not retracting fully after brake pedal release. Serviced the calipers, pistons and flushed brake fluid. Problem solved.
