Would this make the OBD port unavailable? I checked all the under hood and in-cab fuses and they are good. Will check again.

Again, would this make the OBD port unavailable? The glow plugs where changed not long ago as were the harnesses. I will check them but shouldn't I be able to check the codes? Just trying to figure out why I cant get a scanner connected.
