New Battery= CEL
 

Had my battery replaced today (2nd one I've gone through in 30k mi) and the first time I started the car, The TCS light went on. The 2nd time I started the car, TSC went back off but now I have a check engine light. I have driving the car like twice since and the check engine is still on. Any ideas??

sounds like a loose // inadequate ground.. just use a grounding kit to solve the issue
