Thanks Guys. Sorry for the confusion. :seeya
Had the same thing happen to me. Four individual technicians at Four different Chevrolet dealers had no clue what they meant. Best bet is to go through and clear all your codes....key off, remove your negative cable from your battery for about 3 minutes and replace. Drive it a couple of days and check your codes again. Mine came back with the same codes, but they were complete without all the crazy stuff. Good Luck
