6 FAQs about [Do low voltage system power the airbags]

Do airbags need power to deploy?

No, airbags require power to deploy. If you’re in a collision and your car’s battery is disconnected or dead, the airbags will not deploy. However, some newer cars have backup power systems that can provide enough power to deploy the airbags in a collision. The answer to the question depends on the technology and occupants found inside the vehicle.

Why is the airbag light on?

The airbag light (or SRS light) activates when something is wrong with your SRS system. The light depicts a seated person wearing their seatbelt with a circle (airbag) in front of them. It can shine red or amber or display the words ‘AIRBAG.’ But why is the airbag light on in the first place? We’ve got some possible answers. Keep reading.

Why is my airbag not working?

Each airbag component on the circuit gets power running through a specifically designated fuse. An overcurrent event from a short or spike in the system can blow this fuse cutting off power flow. Warning lights alert of lost power caused by a spent fuse needing replacement.

What happens if an airbag module fails?

If the module itself fails due to an internal error, water damage, or other cause, crash data inputs can fail to deploy airbags as needed. In cases of a module malfunction, the airbag light may come on even when the rest of the system is completely functional. See Also: Average Airbag Replacement Costs

Why do airbags not deploy if the car is turned off?

When an accident or impact occurs while the car is parked, the airbags will not deploy if the car is turned off. The lack of power is not so much an issue, as airbags only need the power to trigger the activation. Models that have passenger occupancy sensors should trigger the airbags if passengers are present.
