Can someone help. I have a 2002 corvette with 21,000 miles. Today my dic warning messages came on reading: service abs, service traction system and service active handling. Along with the abs and traction control system warning lights. The manual does say that if you have a problem with the abs the other 2 messages will come on. Less than 50 miles ago i had new tires and a allignment done. (AT A NON CHEVY DEALER). Could they have done something wrong to to activate these warnings?? Thanks dave
