I have the same thing going on, but my spoiler is also staying up and the light for it is blinking.

Can anyone who has had this light come on verify whether or not the TC would work when the light was on. I have been having the issue for about 2 weeks and my TC does not function and I can not lower my spoiler, any one have any other suggestions?? I have already left the negative disconnected, tire pressure is fine, battery is new and problem still persists.
