2016 Freightliner starting issues...

Not really I need help and no one was answering. I drive a 2016 Freightliner and I am laying down after I turned the engine idle on and the truck started up then almost immediately shut off. A few mins later it beeped but didn’t start up. I restarted the truck and noticed that the engine light is on and now the idle management won’t work!! It just won’t turn on. Any idea why?? **sorry about the click bait**

 

Didn’t work. Already tried.

 

Thanks!

 

It’s not throwing any codes....

 

Yes and the idle management won’t turn on now.
