Followed this DIY up to the clean disk part. After reading that so many were able to remedy the situation by just cleaning the disk I did the same and it worked for me. No more lights on the dash. I'm pretty convinced now that this problem is mostly caused by the crystal-like buildup on the scan disc. I'm not saying this is the solution for everyone with the DSC and Yellow brake light warnings but it seems 95% of the time it is the scan disc.

I cleaned it off with 91% alcohol.
I did not clean the infrared light, just the front side of the disc.

Did this about 2 months ago and still no reoccurrences. Even if it comes back because of more buildup, I don't see it happening anytime soon and when it does its way cheaper to just clean again then pay $500+ for the part.
