Does anything have to be done with the tire pressure monitor system if you include the spare in a tire rotation...The EVIC shows the pressure of the 4 tires, how does it know to now read the spare as a working tire...
The 2013 sensors are read by the computer. It only reads whats on the wheel base in motion. Each tire/wheel has a sensor including the spare. When the spare is mounted on the tailgate it is not being read. All the others are and will be regardless of which you use.
The ones moving are sending info to the computer.

Can you cite where you obtained that piece of information? I just bought a 2013 and swapped the tires and rims off my 2012. The TPMS isn't working. While that would seem to support your statement, I have read other posts (AEV Forum) that stated the 2013 did read older sensors. I tend to believe it doesn't. However, I would like some further info before I buy a whole new set of wheel sensors.
I always rotate five. Like others have said waste of tire if it just sits on the tailgate. And if you need to put in four wheel drive all wheels have to be close in size or it cause damage to the diffs so I have been told.
I just did a 5 wheel rotation and I can't get the computer to recognize the front driver side tire pressure. I have driven about 300 miles so it has has plenty of time to sync up. The tire that's out isn't the one that was the spare. I'm thinking i may have to have them reset at discount tire. Any ideas? Below is the way I rotated them.
