had engine out to replace gasket and now have check engine on digital display.
seems to run fine. came on when first starting engine after reinstall.
Any way to reset w/out B.U.D.S system?
You have an active fault, so you cannot "reset" it. You need to figure out what the fault is, so you either need to take it to someone with buds or buy a Candoopro system and do it yourself.
