bilbo71 Posted March 13, 2009 Posted March 13, 2009 2003 Silverado 5.3 has Reduced Power message on the DIC. Scanner readout says code P1518. Checked the main fuse panel under the hood and found the ETC/ECM 15amp fuse was blown, replaced fuse turned key on and the fuse blew again. Anyone know what system this fuse is for?
