As far as i know, the air bag system DOES communicate on the Class 2 databus, but should not have any influence from the radio being removed. There are many things in GM cars that communicate via class 2 including but not limited to the BCM, PCM, Radio, Airbag Module, Instrument Cluster, Onstar VCIM, XM Module, Audio Amplifiers, Remote keyless entry module, etc..

The whole airbag going of when the radio is removed was some freak occurrence that happened on the J-Bodies for no apparent reason.
