You could try to reset the airbag module...

In scantool go Edit->Properties->Options and place a checkmark next to Active Module Detection;
then connect to OBD-II port and do Info->Validate Modules.

In actively detecting all the modules on the serial bus, this may or may not cause each one to reset...

If the airbag module does reset, and it does not have a serious problem, the airbag light may shut off.

I emphasized the word "may".

I was able to reset the BCM like this on my Mrs' N-body (it was throwing codes and preventing engine start).
