I am not sure but I would think it would monitor each tire individually or you could end up with all 4 tires losing pressure and never know it.
My valve caps show 34 psi and do not activate until the drop is about 28 psi. I saw my valve cap asow yellow and then red as it dropped.
I do not know what the computer does, but if you look at the indidual valve caps as you go around the truck you can
readily see which tires are low.
