S70 air bag removal/disconnect

Post by Derbyrunner » Fri Aug 19, 2016 7:01 pm

I hope I don't hurt anyone's feelings but I bought a S70 for son to start out in circle track with. How or is it even possible to disconnect or remove airbags? If sensors are cut or unplugged will this set off a safety switch disabling the engine. Thanks in advance

The steering wheel bag can be removed completely with relative ease but the SIPS bag on the side of the seat is a bigger challenge. There is a safety device that slides into the trigger that is supposed to disable the SIPS but I don't know that I would trust it in a racing environment. A Recaro racing seat would take care of that.

For the dash bag I would just unplug it and not worry about it unless you want to start stripping out the dash to save weight.

There is no interlock that kills the engine if they are disabled.

Thanks Lee! I'm all in favor of leaving as much of dash in place just avoid the possibility of getting snip happy and trying to chase down the appropriate cut wires

Managed to get side bags our fairly easy. Now to work on front cabin bags in the morning. Would there be a simple plug like the ones on the side ?

They all have an orange wire that goes to a connector on the airbag itself. On the steering wheel bag I don't know that I would trust just unplugging it. The passenger's side dash bag is easily accessible if you remove the glove box. The seat belts have an air bag of sorts in that there is an explosive device that tightens the seat belts when the system is triggered. I'm not sure if you are even going to deal with the stock seat belts but they are there. The controller that triggers all of them (except the SIPS bags in the seats) is under the center console just behind the shifter. The SIPS bags are not even electronically controlled, they are mechanically actuated and the orange plastic safety is supposed to disable them.

One of our members posted a video of the SIPS bag being intentionally triggered.
