So, who is running Freightliner Cascadias with the Predictive Cruise Control option?
Have you had any trouble with them? Specifically, no GPS signals in the cab while the Predictive Cruise Control box (IPPC) is powered?
My situation: I have two of them. They are 2017 models with consecutive serial numbers. The first one has been an intermittent problem since it was new, but over the past year graduated to a persistent problem. Every time you turned on the key, you could not get GPS signals inside the cab. The second one started giving trouble a few months ago.
We initially took up the problem with our dealer partner, but they were pretty much clueless as w to what the problem could be. Subsequently it was bumped up to the Detroit regional service rep., and the Freightliner service rep. They too had no idea what the issue could be, and escalated the issue to Daimler's electrical engineers. They were stumped as well.
So, we fixed it ourselves. It turns out that the issue is the IPPC box located in the center of the cab header. There is an access panel up there you have to open, and once open you will see two boxes in there. One is black, and the other is silver. The black one is the Virtual Tech (VT) box. The silver one is the IPPC box.
The IPPC box has two connections on it, one for the antennae, and the other for the power/data bus. Unplug both connections and the problem of no GPS signals goes away.
