Are you driving with an illuminated airbag sign? Don’t ignore it. According to the National Highway Traffic Safety Administration, “In 2016 alone, air bags are estimated to have saved 2,756 people. Additionally, NHTSA estimates that the combination of an air bag plus a seat belt reduces the risk of death in frontal crashes by 61 percent.” These statistics prove that airbags are indeed effective and important for driver safety. If your airbag system is compromised, the sign on your dashboard will turn on and let you know it needs to be inspected. To find out why your airbag light is illuminated, continue reading our blog.

Depleted Airbag Backup Battery

Your vehicle’s airbags have a backup battery in case the car’s main battery is damaged during an accident. However, the backup battery is charged by the main battery, so if the car battery is depleted, then the backup battery will likely be affected too. The light will usually turn off when the car battery is fully charged. Although, the light might stay on due to a soft-code error. You can reset it at home, but Mechanicbase warns “All work done to the airbag system should be made by professionals if you are not 100% sure of what you are doing!”

Damaged Impact Sensors

Impact sensors are placed throughout the body of your vehicle to alert when a crash is happening. On impact, the sensors send a signal to the airbag module and let it know to deploy the airbags. Unfortunately, if these sensors or wires are damaged, your airbag module might not know when to deploy, which can be a safety hazard and dangerous for you and your front passengers.

Clock Springs

The components that deploy your airbags are called clock springs. These springs are actually wires that conduct electricity from the module to the airbags, which are located in your steering wheel. If these wires become brittle or worn out, they are less reliable. Clock springs are prone to failure in older vehicles, especially if they are mechanical. Your local mechanic will scan the car for error codes and can inspect for any further problems.
