You probably have your answer by now, but for the next person... Sounds like you have the infamous "light trifecta" of ABS, DSC, & tire pressure. It's a wheel speed sensor (had it twice now). Problem is figuring out which one. I got the code read for free the first time to diagnose it as the driver front. My hubby first tried to reseat it (as one Google recommendation suggested); no go. So I bought a new Beck-Arnley one from Rock Auto and my hubby installed it. 3-4 months later, lights were back on. This time I had to pay someone to read the code ($70). Turned out to be the same driver front. I contacted Rock Auto. They told me the part was still under warranty, so they sent me a new one. My hubby uninstalled the old one, installed the new one, I sent the old one back to Rock, and it's been good ever since (4 mos now). Hopefully it was just a bum B-A product the first time. Here's a link to someone posting instructions with pictures on how to DYI...http://www.northamericanmotoring.com/forums/stock-problems-issues/150435-light-trifecta-abs-dsc-tire-pressure-3.html
