Report "I have a 2000 cadillac catera and I'm worried that if I spend a fortune to get all of the problems fixed, more problems will appear. My problems seems to be common with this model because when I looked it up, I found that I'm not the only one. My speedo stopped working and my dash is lit up like a christmas tree. The lights that are on are: check engine, abs and tc. I'm hearing that all of these problems are related to the ebtcm (electronic brake traction control module) If so, is this expensive to replace? and can I do it myself? What else could it be?"
