Bigtom,

I've been having that issue for a while now. I was told that it is the DSC/Antilock brake module, the part is $1200-$1500 (depending on where you go) but I was told that Modulemaster.com will rebuild it for $300 and guarantees their work. I plan to send mine to them but I havent found anyone that can remove the part for me. It is driveable even after the part is removed. Let me know what the "stealer" tells you.
