Chassis node power input

[alborz]

I get these two masseges on dash
chassis node power input, check fuse
fault code: 5127
primary fog lamps fault
fault code: 2388

I checked all fuses in engine compartment and inside the cap. all good and have power.
The chassis code on and off appears on the dash, but the primary fog code is constant. No power at the bulb lights and they'er good.
2015 Peterbilt 579
Any input will be appreciated.
