Air gauges going nuts with alarm

[Barneyb]

I know this has been discussed before but couldn’t find it. My air gauges go nuts once and awhile. Usually a couple times a year. This trip (Ohio to Texas and back) they are doing it 50% of the trip. I remember reading about a bad cold solder connection at a main plug somewhere.
If anyone has pictures or specific information of where to look for this I would greatly appreciate it.

Thank you, Barney

I had a similar issue and called Freightliner 800 number. They told me where the control module was, and how to remove it. I got the part number and gave them my vin and for a fee they sent me a new control module. The CM has wires and air lines going to it.

It has been several years and the info above is the best I can remember.
