4 Reasons Why My SRS Light/Airbag Light is On

It is hard to miss that red, glaring light staring right into your eyes. I guess that’s the main intention of the manufacturer, to make the SRS light hard to miss.

The SRS light is an extra safety feature installed in your car.

Understanding what it means and how it works is vital to improving your safety and that of your passengers.

In this article, you will find out what SRS light means, why it may be on, how the SRS system works, common causes of SRS light, and how to reset the SRS light.

What does SRS light mean?

The abbreviation SRS refers to Supplemental Restraint System and is also commonly referred to as the airbag system light. A warning light tells you something is wrong with your airbag system.

The SRS also works with the seat belt by enhancing passenger safety in case there is a collision.

The SRS automatically activates airbags and tightens seat belts for extra safety measures.

If any problem is detected in the system, your car will signal you by turning on its SRS warning light on your dashboard or computer display.

When your ignition is first turned on, the SRS light shows up on your dashboard with other warning lights. If the airbag is working properly, the SRS light should go off within seconds.

But if it doesn’t, there’s a problem, and the system has been disabled. This means that the airbags will not deploy in an accident.

Understanding the basic SRS system

The SRS consists of a few basic components such as an airbag warning light, module, clock spring connector, and crash sensor. Some advanced airbag systems may contain extra components.

The airbag warning light is the warning light for the airbag system.

The airbag module contains the airbag and the inflator assembly. The function of the airbag inflator is to quickly inflate the airbag so that when it is activated, it can protect the occupants in the car.

The clock spring connector ensures an uninterrupted connection to the airbag module while allowing the turning of the steering wheel.

The crash sensor is what detects crash impact through vibration.

In an accident, the crash impact is detected by the crash sensors. The sensor sends the signal to the airbag module to deploy the airbags to protect the vehicle occupants from physical harm.

Older vehicles only contain a few airbags, while modern vehicles may contain up to 10 airbag modules in various configurations.

SRS Light On

Common causes of SRS light 

Your SRS light can be on for several reasons; here are the most common reasons why it can be on:

1. Seat Belt Issue: A false airbag warning light could be triggered if the system thinks the seatbelt is not fastened. It may result from a faulty seat belt or a problem with the sensor.

To repair this, check for anything stuck in the seat belt buckle that may interfere with the sensor.

2. Small accident: if your car was involved in a small accident that didn’t need the airbags to deploy. This could affect your SRS and cause the warning lights to be illuminated.

Have your mechanic reset the SRS computer for normal operation to repair this.

3. Depleted battery: a dead battery can cause your backup battery to be depleted, and this could signal the airbag light will come on.

To repair this, recharge or replace your battery if it doesn’t correct itself when the battery is fully charged.

4. Faulty Sensors: your car sensor can develop a fault for many reasons, which can trigger the illumination of the SRS light.

To repair it, get a mechanic to check your car.


 How to reset your SRS? 

You can reset your SRS either way:

1. Take your car to a mechanic

Take your car to a mechanic to diagnose the problem and get it fixed. Once the problem is fixed, the SRS light will be turned off.

2. Use an SRS OBD2 Scanner

You can manually reset the airbag system with an SRS OBD2 scanner.

An OBD2 scanner is a diagnostic tool that you connect to the OBD2 port in your car. This scanner can use either wireless or wired technology.

This scanner can help you diagnose any issue in your vehicle’s internal airbag system. It does this by accessing the stored data in your airbag control unit and then evaluating it to identify the problem. Once the diagnosis is finished, it retrieves an error code that will help you figure out how to fix the issue.

Some scanners may give information on the revealed code, but others may not. You can easily check the internet for the error code meaning and how to fix it. You must fix the problem before clearing the codes.

The OBD2 scanner provides solutions to complex car issues and resets the SRS. When purchasing a scanner, pick one compatible with your vehicle and has SRS capability to read and perform an airbag light reset. The OBD2 scanners can save both time and money compared to taking it to the mechanic.


If your SRS light is turned on your dashboard, it means the safety feature in your vehicle has been disabled. Although your vehicle will still function with the airbag light, driving with a malfunctioning airbag system is not safe.

Pending when the issue is diagnosed and fixed, your airbags will not deploy. It’s better to be on the safe side by getting it checked by a trusted mechanic or using an SRS OBD2 scan if you’re mechanically inclined.
