I was changing my under the hood fuel filter on my 13-6.7L.

Noticed my communication cable was unplugged and dangling.

I never change my tunes, I’ve kept it on 1 tune for about a year.

My question is will any harm come with the communication cable not being plugged in and the truck running daily?

I can’t say his long it’s been unplugged. Just noticed this morning.

Oilfield truck. Lots of bumpy ugly roads driven daily is what I believe caused the un-plug.

Any help is appreciated. Thanks!
