ESC failure light keeps coming one!

Please help! I am at wit's end! I bought a 2012 base Kia Soul, manual transmission. Everything is great but the ESC failure light keeps coming on. It stays on and I have tried many things to get rid of it and reset it on my ODB reader, but it comes back within a few times of driving.

Things that I have done to try to fix it:
  • Replaced clutch switch
  • Replaced brake switch
  • Sanded paint off of both grounds in the engine compartment
  • Changed brake light bulbs

These were all suggestions that I found on the internet, but alas, the problem continues. I do get a c1520 error message when I check the ABS codes, when I reset it the ESC light goes off but then comes back on as I mentioned earlier.

The only thing that I know of that was moded on the car is that a power door look and FAB was added. I am wondering if somehow that is shorting out the ESC?!? I am going to try replacing the Rail RH fuse too as that says the ESC runs off of it.

Really I don't think that there is any problem driving the car with the light on as the ESC might still be working, and I live in SoCal so not much rain and no snow to worry about causing traction issues, but this has become a bit of an obsession to solve the problem.

Any thoughts? Thanks in advance and BTW love the Soul. We bought 2 2012s within the last year, both manual base, just different colors.
Might be a stupid question, but do you have led brake lights?
