That information would be hugely more useful than simply giving a global
"Tire Sensor Management System Malfunction" error, which is simply brainless.

I also agree it is stupid... but I'm guessing there's a reason for it.
You could always test by putting on 3 tires from your summer set and one of the winter, one wheel at a time... but that would be a major PITA. I'd just take it anywhere that can test TPMS and they should be able to figure it out.
