$325 on a 2005 suburban at my mechanics garage.
The light in on because there is a problem with the SRS. What and how much to fix? Only a trained professional can tell you that. This is not a DIY repair. Take it to a professional.
around 40 pounds the sensor is broken
fix the airbag.
The airbag light is on because the airbag module detects a problem with the system. Fix the problem and the light will go out by itself.
smack it with a hammer
Fixing the YLOD on the PS3 will cost $150.00.
You would have to take it to a Ford dealership so they could diagnose why the airbag light is on. It is not something that you would want to do yourself.
You can't "clear" it unless you fix the problem that is causing the light to be on in the first place. That's the way all airbag systems work.
fix airbag fault & serv light will go out
Go to a qualified mechanic. The warning light indicates some is wrong. A inadvertent deployment of the airbag will most certainly injure occupants.
Have a trained technician check it for codes and repair the cause.
