Everything You Need to Know About Airbags: A Simple Guide

Although airbags are the safety net between you and a potential car accident, the flickering of your airbag light may not exactly make you feel safe. Before you panic, we’ve compiled a few things you should know about your airbags so that you’ll know what to do when the situation calls for it.

Airbags Have Various Warning Lights

If your airbag light is on, there may be some concerns you need to attend to. Typically, your airbag light turns on when there are complications within the unit. It could be possible that its backup battery is depleted, or it is faulty. Whatever the case, it’s best to take a look as soon as you can.

These are milder situations. At most, they will require immediate attention, but it doesn’t mean your vehicle was sent careening into the highway. But this may not always be the case. 

Make sure to familiarize yourself with your vehicle’s manual so that you know which airbag signals mean which. If your airbag lights stay on for a long period of time, take some time to examine the airbag unit when you can. 

There Are Two Types of Airbag Sensors

Airbags are triggered by built-in sensors placed within the vehicle. This determines whether or not an accident has occurred, and it needs to pop the airbags. Some vehicles have more than one sensor in place, whereas others have it concentrated on one area.

Modern vehicles typically have two kinds of sensors: the mass sensor and the roller sensor. Mass sensors measure impact and can be found in the front of the vehicle. Meanwhile, roller sensors measure the intensity of an impact through a coil system.

Airbag Locations May Vary from Car to Car

Like your airbag sensors, the location of your airbag may vary depending on your vehicle. In fact, it is highly possible that your car has more than one airbag present.

On average, airbags usually pop up from your front bumper or fender. There are also airbags on the rear of the vehicle or near the passenger seat. Again, make sure you know how your vehicle model works.

Knowing these spots is important in the case of an accident befalling upon you.

You Can Reset Your Airbag Sensor

If you’ve figured out what your airbag light is signaling, you can reset your airbag sensor. If you have an OBD2 scanner with you, you can easily reset your sensor without even having to find it. Make sure that you disconnect and reconnect the vehicle’s battery when you do.

Remove your terminal clamp and don’t put it back until about 5-10 seconds have passed. When you put your battery back, the airbag light should stay off. If it still stays on, then you should take your vehicle to a mechanic and conduct a full scan to diagnose the problem.


If taken care of properly, your airbags will have your back in any potential accident. Proper care and maintenance of your airbags are needed to ensure that they work when you need them to.
