Default Check Engine Light Keeps Coming ON

The check engine light comes on while I'm riding my 07 Ultra. It comes on and goes off for a while. I took it to the dealer and they said that they just had to clear a code in the ecm. It stayed off for about ten miles and then started doing it again. The bike is running fine. Is anyone else having this problem?

My Heritage Classic would have the engine light come on, the fuel light come on, the security light come on and the speedo would be dead. Shut off and restort and everything was fine. Dealer said is was a turn signal code and cleared it. 15 miles happened again. I also have a Thundermax ECM, turns out when I uploaded new firmware for the ECU it had a "bug." They came out with new firmware, uploaded it and have not seen the problem in 3,000 miles.

I noticed you have a PCIII installed on your bike. After I added the PCIII to my '07 SG I started having the exact same thing happen to me. It seems to come on more frequently when I get on the throttle. If I'm riding mellow I never see it.
