Toyota Repair: 06 rav 4, tire air pressure, toyota dealer

Question
my airbag light and tire pressure light both come on about the same time tire air pressure is fine what can i do to fix it my self

Answer
I need to know which tire pressure warning system it has, are the valve stems made out of rubber or metal? The air bag system has nothing to do with the tire light and is a seperate problem, you would need to have the toyota dealer scan the onboard system for failure codes.
