Brake Lights Always On "EPC"

I recently bought a 02' Jetta. The warning light for EPC came on. Soon after, I discovered the brake lights to be stuck on all the time. The brakes and engine are doing well. I pulled the fuse and parked the Jetta. What is EPC/ Electronic Power control?

So...Ya...Im repling to my own post. I went to the dealer and I was told that it was the brake light switch. Fixed free under warranty.

and that did cure the problem??

Sure thing, Problem fixed.
