Helping out a friend here if you know please help we are trying to figure this one out

Right now he is unable to tune his car or read codes off his OBD-II port becasue the port is not giving out any power so we think it is the fuse. Any input would be great.

 

check the cigar fuse i think

 

is in the fuse panel on the passenger side, just look at the diagram it will say diagnostic ecm fuse.

 

That was easy.
