The AFCAD for PHNL hasn't been updated since 2012 and, since its ILS data is exactly the same as the one from the default scenery, we haven't duplicated them in the scenery, so the sim will use the ILS from the underlying default scenery.
There was a thread here some years ago, where it was also assumed that PHNL must have had some kind of problem, because the ILS didn't show up in FSC commander, although the worked in the sim.
http://www.fsdreamteam.com/forum/index.php/topic,2736.0.htmlSo, apparently, the reason why you don't have the ILS, might be that you must have changed something in the default scenery, maybe you update the default navdata ?
In any case, even if I still think is not a good idea to duplicate the stock navaids in an add-on scenery, if they are unchanged from the default (resulting to have to chase all the duplicate data if there IS an update), if you run the FSDT Live Update now, it will download an update AFCAD for PHNL, which duplicates the default ILS, so it should always work, regardless of the status of your default navdata.
