Peterbilt 579 2025 metal noise and white smoke

You can do it. The company doesn’t need to know.

 

Just pull the fuse for the horn. Put it back in before you go to a terminal.

 

Much simpler. Why didn’t I think of that? Lol

 

Yep company truck = drive it like you stole it. If the noise gets too bad just turn up the radio.

 

Don't worry about the horn.
Let the truck idle at the proper rpm and start and stop on its own. That's the point of the system. If you keep doing what your doing it's going to derate and then your screwed. You should be taking care of a new company truck even it's it's not yours.

 

Disconnect the horn, they are usually on top of the firewall behind the engine, your company can also go into the BIOS in the computer and change that option and make it stop. If someone has a horn honking every time the truck wanted to start right next to me when I am sleeping I am going to get pissed. I am usually pretty much live and let live type of guy but that would get me going
