2015 International Prostar electrical problem

I have had all of the above problems. Is the truck equipped with the bendix wingman system?

 

My experience has been the ABS and traction control issues are coming from that. What works sometimes is to unplug the radar box for a few minutes and plug ot back in. I assume you have no cruise control when the ABS and traction control lights come on. I used to have to pull the fuse for the bendix every night when I went to bed and plug it back in before I started the truck in the morning.
The nox sensor issue is intermittent and will go away when the readings normalize. I purchased a reset tool that would clear that code. I had my Prostar for just over a year, traded it in November 2019. I hope the government doesn't mandate all new production trucks to have a bendix system as they are junk and nobody knows how to work on them. My new LT does not have it.
Anymore questions I"ll do my best to help.

 

I don't know about the radar being loose, but wiring for sure. The question is where??? Becareful when tightening the radar not to knock it out of alignment.
Good luck.

 

Have the same problem. Wheel sensors are usually reason for Abs but fixed nox and light keeps coming on.
