Uhhh, I'm not sure. Try it.

I know the light will go out if you disconnect the battery.

Wouldn't disconnecting the battery potentially erase the fault code from the computer's memory? Or would that have to be done with a scan tool? I had the same problem with the airbag system on a 98 S10 I used to own. The light would come and go randomly while I drove. I never bothered to look into it too deeply since I was uncomfortable with messing with the system for fear of accidentally setting it off! It must be a fairly common issue on that era of trucks.

Yes it will erase the codes if you disco the battery. But if he did all the stuff I posted and then after reconnecting the battery the light came back on, then there is still an issue. The only time I've seen an airbag go off is when an impact sensor triggers a deployment, we purposely set one off for fun night the floor in the shop and one time a stereo shop cut and connected the wrong wires and set the air bags off in a customer vehicles. But granted they could have had the key on when they were cutting and connecting wires or they just flat out weren't paying attention.

A shorted or broken wire shouldn't set them off because the computer sees a voltage drop or spike but no signal from an impact sensor to command a deployment so it turns the light on to tell you the system needs to be checked.

That's what I figured, but it's always that paranoia that lingers in the back of your head. Although I did worry while driving that truck with the light on. It's that what if scenario. What if the light was on while driving and you got into an accident? Would that cause the airbag to not deploy? Maybe, maybe not. I never bothered to get it fixed though and wound up trading that truck in so I guess it's a moot point for my scenario. But I thought I'd throw my experience out there and see if it might help.
