The other morning, I went out to the garage and turned on my Spyder (2008 SE5 40.235 miles).  Put in the key, turned her on, and kitted out to ride.  I look down and have a VSS Fault, Check DPS, and Limp Home Mode.  I had ridden the night before with no problems.  Get it to the shop.  Dealer calls and asks, "How long have I had the floorboards installed?"  Answer: 6 months  "What other changes have I made?"  Answer: Replaced brake lights just over a week earlier with LED bulbs.  Could that be the cause?
