What is what does it mean when your airbag light comes on?

The airbag light illuminating on your dashboard indicates a problem within your vehicle's Supplemental Restraint System (SRS), which includes the airbags. It means the system may not function properly in the event of a collision.

Here's what it could signify:

• Malfunctioning airbag sensor: Sensors detect impacts and trigger airbag deployment. A faulty sensor can prevent proper deployment or even cause accidental deployment.

• Faulty clock spring: The clock spring allows the steering wheel to turn while maintaining an electrical connection to the airbag. Damage can disrupt this connection.

• Problems with the airbag control module (ACM): The ACM is the brain of the system. It monitors sensors and controls airbag deployment. Malfunctions here can be serious.

• Low battery voltage: In some vehicles, a low battery can trigger the light.

• Seat belt pretensioner issues: These are part of the SRS and work with the airbags.

• Damaged wiring or connectors: Corrosion or damage to the wiring connecting the SRS components can cause the light to illuminate.

• Previous accident: Even if the airbags didn't deploy in a prior accident, the system might need to be reset or repaired.

• System fault code present: A diagnostic scan is necessary to determine the specific issue.
