2020 Freightliner won't start, multiple trips to the shop.

Good god man get the stick out of your butt.

 

So these are the guys who say 'wow, dig that, it is a little engine that is yellow'

 

WTF are you talking about?

 

Being a 2020 it may be a emission code. If the truck is near the trade cycle,it’s cheaper to put it in a regen and kick it down the road than to replace the one box.

 

Mil lights come on. Sometimes it means a code was tripped and went away. But mil lights stays on for like 3 days and then turns off. Other times it's an active code. But not of something that's gonna to derate you.

 

Temperature sensor on the coolant tank.Unplug until it’s replaced.Red light will go off but yellow stays on
