On a dd16 what’s the air control module do?

I pulled it out of a truck because it started to smoke and it melted a little bit! Not sure what it even does google doesn’t tell me anything besides finding stuff on the throttle body. Everything works tested it all out, PASDL2A is the part number on it! Google tells me it’s the westernstar plug air control module!! So is it okay if the truck runs without it? For a day so it can work? Thanks
