I was having the same issue and just disconnected the hood switch cabling completely. This not only solved my 3 am alarms for no reason but also allows the car to arm the rest of the system, by beeping and flashing lights when arming with the keyfob.

That is because the check light indicated on OBD2System FaultYou replaced a part based on the codeThe codes are used to diagnose the system that setthe code & then component testYou apparently didn't diagnose the real cause of thepossible problemThe sensor may have been just doing it's jobWhen you come here either give use the codes orjust Google them to learn the ins & outs

That light is letting you know that there is insufficient weight on the seat - so the sensor did not turn on the airbag.

The next time you turn the vehicle on - it will do the same... if there is not ??45lbs?? in the seat.

If there is nobody in the seat and the light goes out - the sensor (or under-seat wiring) is bad.
