you should buy a repair manual that shows you all the codes

underneth the radio and the carpet you see a plastic cover take that cover off you see the ecu held down with 4 bolts take the bolts of and spin put the key to the on postion the ecu around there a screw thing on the back turn it left for 2 sec and turn it back to the postion it was in itthe cel will blink the codes .do the same process over and the codes will erase
