It happened to meupdate on my DRL's. Took it to the dealer to recode, they said the BCM was bad and installed a new one. They did NOT add the sales code, regardless they are functioning. The dash is giving an error light, although the lights function perfectly and have been for about a week.
They added like like three sale codes and my drl worked just fine but I was still getting the light bulb out in the dash and I ended up buying the tazer and that worked
No more hyper flash or error codes In the dash
