For what its worth, its really possible to trigger the airbags with the car off.
I recommend having connecting the scanner and just clear the codes and be done with it.... testing the airbag systems while live has potential for triggering.
The following pictures are from a customer car I was working on when the airbags went off. W220 2004 S500.
The key was off (battery connected, however) and I was programming the new CGW module that was just installed. When the computer programs the CGW, it also (briefly) codes the SRS module with the new serial number of the CGW.
I was sitting on the driver seat, leaning into the center console and playing with my phone while the programming was going on. The laptop was on my stomach with the lid resting on the steering wheel.
When the programming went to roughly 70% indicated -- i don't remember exactly -- the airbag suddenly went off. This is with the key out, mind you. Beside a demolished laptop (and wasn't that a pain to set up the new laptop to just how I like it, plus reinstalling all the softwares, etc), I was fine...due to my leaning into the center console, I completely missed the airbag.
Damn thing went off like a gunshot, with the sound and everything. Scared the crap out of me.
As it turns out, the car was a salvage car (thanks to CA flood) and the customer neglected to inform me of that little fact. It was submerged up all the way to the navigation.
Sooooo.....play it safe and take it to a shop to plug it in the scanner and be done with it.
