Well it is possible. What code did it flash? Take the code that it flashed and come back a do a search. Some have had a lot of luck with cleaning the connections of the front crash sensor's.NOT FOR THE FAINT OF HEART!!. Please, read through the post to find out how they keep the system from thinking it was in a wreck.
Another cause could be a weak battery. Yeah I know, sounds stupid, but many of us (me included) have had their air bag light flash at odd times and found it was a slowly dying battery. Mine flashed a code 35 or something like that, that would be three pulses followed by 5 pulses.
