Airbag Warning Light: What It’s For, Why It’s On, and How MyMechanic Can Help

The airbags in your vehicle are an essential safety feature and can save lives in the event of a collision. If something is wrong with the system, the airbag warning light will alert you. Here's everything you need to know about this warning light and how MyMechanic can help you resolve the issue.

What is the Airbag Warning Light?

The airbag system, part of the Supplemental Restraint System (SRS), works alongside seat belts to protect you and your passengers during a collision. The SRS warning light looks like a side profile of a seated person with a circle (the airbag) in front of them. If this light stays on or activates while you’re driving, it indicates an issue with the airbags or another SRS component.

Why the Airbag Warning Light Comes On

Many factors can cause the airbag warning light to activate. Below are some common problems and how MyMechanic can assist:

1. Seat Belt Latch Problem

Foreign objects in the seat belt buckle can interfere with the system, triggering the warning light.

Solution: Inspect and clean the buckle, reset the system, and ensure proper functionality.

2. Passenger Seat Sensor Malfunction

The passenger seat sensor detects if the seat is occupied and adjusts airbag deployment accordingly. A malfunction can cause the warning light.

Solution: Check the wiring and sensor, repair or replace faulty parts, and reset the SRS computer.

3. Corrosion from Water Damage

Water damage can corrode SRS components, causing system failure.

Solution: Replace corroded parts and ensure the system is functional.

4. Faulty Clock Spring

The clock spring in your steering wheel maintains electrical contact between the airbag and SRS computer. A broken clock spring can prevent airbag deployment.

Solution: Replace the clock spring and reset the system.

5. Drained SRS Backup Battery

A low car battery can deplete the SRS backup battery, activating the warning light.

Solution: Recharge or replace the battery and reset the system.

6. Previous Accidents

Minor collisions that didn’t deploy the airbags may still trigger crash sensors, causing the light to stay on.

Solution: Reset the SRS computer and verify the system’s integrity.

7. SRS Computer Failure

Heat, age, or vibration can damage the SRS computer, leading to system failure.

Solution: Replace the computer and check for extended warranties or recalls.

Can You Drive with the Airbag Light On?

If the airbag light is on, the airbag system won’t function properly, increasing the risk in the event of an accident. Address the issue immediately to avoid safety and insurance complications.
