Default 07 Altima 3.5SE TPMS light blinks then solid

TPMS light flashed and stayed on. That happened only a few miles after driving off the dealer's lot. Thought it was merely a low tire issue but proven wrong. No time to bring back to dealer yet.

Teh twist before the sale was closed: One wheel was swapped from another new 3.5SE on the lot to resolve a scratched up wheel issue.

Anyway, checked cold pressure already. Dealer had 40 psi. Thought over-inflation may be a trigger and therefor lowered all 4 tires to 33 psi (spec) and measured w/ a quality pencil tire gauge. The light still behaves the same way.

Logically, I believe the computer on board has learnt the 4 RF tags/signals from the 4 'original' wheels and suddently, one is gone and is replaced with a RF it does not know.

What is the explanation of my failure mode?

To make the computer re-learn or reset, is there a sequence I can go through myself or I must go back to the dealer?
