hi i got a 97 skylark recently. and ive noticed sometimes the "ETS OFF" light comes on and at the same time the ABS light turns on aswell. it only happens sometimes though and other times only when the parking brake is on. i understand the ETS is traction control , and i know how ABS work since im very familiar with working on cars, just not so much with newer technology. and i was wondering if a regular scan tool can find what code its giving? or do i have to use something special. i dont notice any difference in driving. sometimes the car does hiccup alittle when giving it gas. and it doesnt get the best fuel economy in the world. so other than that it seems to run okay

any suggestions would be great. thanks
