Don’t be surprised if you notice your car’s airbag warning light illuminates on your dashboard. Although it indicates there is something wrong with the airbag system, it means the system won’t deploy during a collision.
Don’t panic if you are experiencing such; I will explain the common causes and how to reset your car’s airbag light. I’ll also explain what to do if the light is on and how to turn it off, so read to the end!
Let’s Begin!
What are the Common Causes of an Airbag Light?
Battery-Related Issues
A low car battery can activate the airbag light, indicating possible power problems affecting the airbag system, much as how a flashlight’s brightness decreases when its charge is low.
The airbag light illuminates when the backup battery in the car becomes low, which results in a report of airbag system failure.
Seatbelt Sensor Failure
For our safety when driving, seatbelts are essential. However, what occurs if there is a fault with the seatbelt sensors? Because the system could think the seatbelt isn’t fastened, this could cause the airbag light to illuminate. If the airbag light comes on, it’s a sensible idea to look for any damage or obstructions that might be preventing the seatbelt from engaging properly.
Passenger weight sensors may be the cause of the issue in some situations. If these sensors mistakenly detect a heavy object on the passenger seat while a seatbelt is in use, the airbag light may illuminate.
Bad Connectors and Wiring
Think of your car’s wiring and connectors as the airbag system’s nervous system. They can cause an airbag light alert on your dashboard when they are damaged or compromised. This could be caused by loose connections beneath the seats, broken wires, or even a worn clock spring in the steering wheel that disconnects the driver’s airbag.
The airbag light may also turn on due to corrosion or physical damage to the airbag control module, signaling the need for expert repair.
To further explain, the airbag light serves as an early warning system, alerting drivers to potential issues before they become major problems. Ignoring the airbag warning light or delaying action risks compromising the safety of passengers.
Damage to wiring and connectors, a depleted car battery, or malfunctioning or damaged sensors can all trigger the airbag light on the dashboard. The cause can be simple or complex, such as a faulty seatbelt sensor or a system requiring a reset after a minor collision.
How to Reset an Airbag Light?
Turn on Your Vehicle Using the Ignition
If there is a problem with the SRS airbag light, you should restart your vehicle using the ignition. Turning on the ignition switch, letting the car sit for ten to twenty seconds, and then turning it off again is how you restart the car.
Then try to get your car started. If you see that the SRS airbag light is off, your problem could have been fixed. During a test drive, make sure the SRS airbag light remains off to confirm that the vehicle functions as intended.
Press the Passenger Airbag Switch
There is a switch in some car models that controls whether the airbag in the passenger seat will activate. The SRS airbag warning light may illuminate on your car if the switch is off. Turning the switch or pressing the button while your car is running will fix this.
Make Sure Your Seat Belts are Working Properly.
In vehicles, a broken seatbelt could trigger an SRS warning system. You should lock and unlock each seatbelt to ensure they are all securely fastened if you think that a loose one may be the source of your airbag light problems.
Ensure The Persanger Weight Sensor is Not Triggered
To decide if a passenger is seated in a seat and how to activate the airbags, your car uses a system called the front passenger occupant system. If you put anything hefty in a seat, your car could think it’s a human.
There are two approaches you might consider for addressing this issue. To completely prevent activating the front passenger occupant system, you can put the item in the trunk. You can fasten the item to the seat and belt it in if you only want the airbag light to go out.
Employ an OBD2 Scanner to Determine the Root Cause of the Problem
You can use an OBD II scanner to diagnose the unknown problem you’re having if you have expertise working on cars or know someone who does. The diagnostic link connection (DLC) should be plugged into the port located beneath the wheel.
To find the problem, wait for a fault code to show up on the scan tool and compare it to a handbook or internet resource. Please proceed with the necessary steps to address your car’s issue or schedule a professional repair after the OBD2 has offered some insight into the problem.
Take a Quick Test Drive to Make Sure the Problem Has Been Fixed
You should drive your car to make sure the issue was rectified before assuming that your SRS airbag light issue has been fully resolved. Most manufacturers advise ten minutes or so of driving.
A quick test drive could potentially resolve an unresolved SRS airbag light issue. Occasionally, the sensor for the front passenger occupant system needs to be reactivated. This reset frequently occurs on a short trip.
So, here is how to reset your airbag warning light in six quick steps:
- Turn the Ignition On and Off
- Take a Quick Test Drive
- Locate and Check the Passenger Airbag Switch
- Check the Seat Belt to Ensure They are Working Properly
- Verify The Passenger Weight Sensor is Triggered
- Use an OBD-II Scanner to Reset the Code

What To Do If Your Airbag Warning Light Comes On?
When an airbag light remains on, it indicates a serious risk that the airbag may not deploy in an accident. If the light persists after trying all the troubleshooting steps, it indicates an advanced issue with the SRS system that requires professional intervention.
This is similar to knowing when to call a plumber when a leak in your kitchen escalates into a flood. Persistent airbag light issues, like a persistent cough, indicate serious problems and require professional attention.
Activated airbag lights pose a significant safety risk, similar to driving with closed eyes. The safest course of action is to seek professional help to diagnose and repair the issue. While it’s not typically illegal to drive with an airbag light on, it can cause vehicles to fail state safety inspections. If you do, the legal ramifications could be severe.
Conclusion
The airbag warning light is more than just a dashboard symbol; it’s a critical indicator of your vehicle’s safety system. Ignoring it can put you and your passengers at risk in the event of an accident.
While a simple reset may work in some cases, the light usually signals an underlying issue such as faulty sensors, damaged wiring, or problems with the airbag control module. Always prioritize safety by diagnosing the root cause before resetting. If you’re unsure, it’s best to consult a certified mechanic or use a professional diagnostic scanner.

Frequently Asked Questions (FAQs)
1. Is it safe to drive with the airbag warning light on?
No, it’s not safe. If the light is on, it means your airbags may not deploy in an accident, leaving you unprotected.
2. Can I reset the airbag light myself?
Yes, in some cases you can reset it by disconnecting the battery or using an OBD-II scanner. However, if the issue is unresolved, the light will come back.
3. What causes the airbag warning light to stay on?
Common causes include:
- Faulty airbag sensors
- Loose or corroded wiring connections
- Dead backup battery in the airbag module
- Recent collision or impact
- Seat belt pretensioner issues
4. How much does it cost to fix an airbag warning light?
It depends on the issue. Minor wiring fixes may cost $50–$150, while replacing an airbag control module can cost $500 or more.
5. Can disconnecting the car battery reset the airbag light?
Yes, sometimes disconnecting the battery for 10–15 minutes resets the system, but this is only temporary if there’s a deeper fault.
6. Will my car pass inspection with the airbag light on?
In most regions, no. A lit airbag warning light is considered a safety issue and can fail vehicle inspections.
7. Do airbags still work if the light is on?
Not necessarily. The light indicates a malfunction, which may prevent airbags from deploying during a crash.
