Um, I'm thinking you should know whether you have daytime running lights or not.
Also, DRL's in 2006 were mostly in Canada only, so if you live in the States, I doubt your 2006 Altima has DRL's.
To answer the other question, if it has DRL's, then there will be a DRL module. Conversely, no running lights, no module.
Those modules do have issues as they get older, and will cause intermittent or hard failures in your headlights.
I have a 2002 Pathfinder, and they have those issues (I replaced my DRL module with one from a junkyard).
if you go to that forum and search DRL's, you'll find some good info.
