Airbag light panel is ON

One of the air bags losing its activation pressure could make the light stay on. I'll guess that they have low air pressure sensors similar to the valve stems on the wheels.

I don't know if you intended this as a bit of humor, but this could not be more incorrect as to how air bags function.

I'm glad to amuse you CT... but even more humorous, I was serious.

Air+ bag = a bag full of air.

What activates airbags?

They are basically little bombs. There is an explosive charge in the squib that is electrically detonated to rapidly fill the bag (with hot, stinky gas, as opposed to air). The SRS system makes sure that they are ready to fire at all times, by running a low voltage through the squib and looking for the voltage drop across it. That allows the system to detect that the squib circuit is open (broken wire) or shorted.

Wow... stinkbombs. Thanks so much for the information CT, I understand now. I had just guessed that they were powered by little CO2 cartridges.
