The Nissan system uses transmitters in the tire.
The systems that work on variations in tire rotation aren't very accurate. I had a 2001 Mustang with ABS and if you had a tire that was significantly under inflated, it would cause the ABS system malfunction indicator light to come on. I had a tire with a slow leak and I could count on the ABS light alerting me when it got significantly lower than normal. I know this was not a smart thing to do (ride around with a tire that had a slow leak). I had ordered new replacement tires and was just waiting for them to arrive. GM cars that used the ABS systems to detect under inflation required a significant learning period. They do work, but I am not sure they work well enough to improve safety. I also think system that use ABS sensor require four channel ABS (a sensor on every wheel) instead of the three channel systems used on many rear wheel drive light trucks.
