I've had two of them there 3 visits for the transmission safety recall, infotainment system updates, and trim work. They scan it every time it comes in, so not sure if the software indicates a device present. My SA knows I have them in there.
Dealer probably won't say anything, but GM might. If my motor grenades, I will make an effort to remove it. That may entail a roadside removal or doing it in the dealer lot when the tow truck drops it off.
You'd have to ask Range if the module is detectable after removal. ECU may stor information showing DFM was not functioning prior to motor stopping.
