Tire Pressure Light On problems of the 2006 Nissan Frontier

We purchased a used 2006 Nissan Frontier with nismo package that had 32,000 miles on it. By the time it had 36,000 miles, the truck seized on the highway. We had it looked at and was told all of the oil had leaked out of the transfer case and the bearings/seals were broken. Also, that several of the transfer case bolts were missing before it was taken apart for inspection. After waiting 3 weeks for the parts to come in, we purchased new tires. The tire pressure light did not reset on the dash board and still tells us the air pressure needs to be checked even though we paid for nitrogen that supposedly keeps the air pressure constant.
