What Are the Common Causes of Airbag Failure?

Airbag repair is usually not the first service you think of when it comes to automotive repairs. However, if you get into an accident and any of your airbags are deployed, they will need to be swapped out. Furthermore, the sensors will need to be reset.


You can also encounter airbag issues, even if you've never had to deploy your airbags before. Your vehicle will tell you by illuminating or flashing the airbag warning light on your dashboard or computer display. When this light is lit up, it usually means your airbags are deactivated. So if the light is on and you get in a collision, the airbags will not release.


Though airbags are rarely used, you never know what can happen on your next commute. An inactive airbag is a severe issue that you will want to correct soon for everyone's safety. Various reasons can explain why your airbags are failing:


Depleted Airbag Backup Battery

If your vehicle's battery is dead, it may have also depleted the backup battery that powers the airbags. It may fix itself once the battery is fully charged again.


Faulty Sensors

Your vehicle has several sensors connected to different components. The sensors link directly to the car's computer system to recognize and notify the driver of potential problems. Sensors can fail or be tripped on accident to cause the airbag warning light to come on. The sensors will need to be inspected, and the system will need to be restored.


Damaged Airbag Clock Spring

The airbag clock spring maintains continuity between the vehicle's electrical wiring and the driver's airbag. It coils in and out whenever you turn the steering wheel. It can deteriorate over time, which causes a weak connection and potential airbag failures.


Wet Airbag Module

If your vehicle has undergone water damage, it could have affected the airbag module located under the driver or passenger seat. If it is shorted out or corroded, it won't work correctly.


Whether your airbag light is on by mistake or through one of these common causes, your airbag warning light is still a cause for concern. You will want to get your airbag system and sensors repaired as soon as possible. For all your airbag repair and diagnostics needs, please call or visit Mazur's Total Automotive.
