OK I think I should clarify that I had recently installed winter tires and had switched from main to 2nd set and tpms warning light stayed on and is still on.I tried Techstream and tpms utility, it showed no ids, no pressures, and I,m not sure of batteries in 2nd position.I moved switch from 2nd to main and techstream then showed ids but not pressures.Tried a pressure initialization and now getting a check system.I might try techstream again when weather warms a bit.All itres are at 34

You need to read the ID # off the sensors on the winter tires and enter them into Techstream for 2nd set. Both sets need unique ID #'s for each tire. 2 sets = 8 tires = 8 unique ID numbers, 4 for each set. My spare tire doesn't have a sensor. Hope this helps.

Ok,just an update to tpms issue.After several tries with techstream to no avail to read winter tire ids ,reset button ,and check system on center screen,I purchased a tpms scanner to read ids .All good ids and batteries.Found tpms ecu was stuck on reset loop ( probably too many presses of reset button.)I reset ecu with several tries with a paper clip across pins 4 and 13 on obd port.Center screen has to show Diag Tire 72 and 77.Then finally got tpms id registration to work on techstream.

You didn't mention whether you are trying to install new sensors or the warning light just came up and you are trying to diagnose it. If you still have all original sensors ant they report nothing, it could mean they are dead.
