in the fuse box...find the ecm fuse...pull it out for a few seconds then put it back in...this fuse may be located in the fuse box or under the hood with the relays...it will be labled ecm or something similar to that...this will save you from disconnecting the battery cable and having to reset all your radio functions.If you can't find the fuse just simply disconnect the negative battery cable for a minute then reconnect it..this will clear the code...but you will have to reset the radio and clock.Hope this helps
