Looks like he has it handled, But just to clarify. Its a Event Data Recorder AKA Sensing & Diagnostic Module. Like the little black box on airplanes. To best explain it... It has an accelerometer and when its tripped it records RPM,TPS,MPH,Braking,Seatbelt on/off. Everything a crash investigator needs to know. If its tripped and your airags dont deploy, The data is erased after 250 ignition cycles. We all have them in are trucks. Some are under the seat, Under the center console or behind the dash. There easy to identify. It has a big yellow sticker. CAUTION AIRBAG SENSOR!!
Problem with just pulling the airbag fuse is the same as just disconnecting the battery. The SDM is a data recorder but also controler that can store energy to deploy the air bag 10 mins after the battery or even the airbag fuse is pulled. There is a long sequence to service them... Battery,Fuse and all service loops... Wait 10 mins. You can short but it and just dissconect the battery and wait 10 mins. There will be no way the airag can deploy.
We had a tech 3 years ago that was removing the stearing wheel on a benz. He disconnected the battery and pulled the fuse. The airbag deployed and broke his jaw. So im alittle anal when it comes to airbags. They scare me now
