I contacted vette pros before purchasing this ebcm & pump for 2002 Corvette, was told it was a good unit out of a low mileage car & was assured it had no abs lights on when removed from car.however when I received the ebcm & pump it had a note that there would be no warranty if ebcm was separated from the pump cause it could damage the ebcm so though I didn't agree with that logic I took the extra time to replace pump & ebcm which is a lot more work only to find out the ebcm had a bad relay
