If the battery is fully charged again, it could automatically correct the issue, but if not, the sensor will need to be reset and the backup battery recharged. The backup battery that powers the airbags may have also run out if your car’s main battery recently drained. The light will turn on if the airbag hasn’t been deployed and the system detects that it can’t activate the airbag, which indicates that there is a problem with the airbag system in your car. The airbag light will be on if your airbag has been deployed and it has not been properly reset.

What would cause the airbag light to come on?

The issue with these particular vehicles is that placing a heavy box or container on the passenger seat is all it takes to trigger the sensors. Most cars have a passenger weight sensor that is highly sensitive. Verify if the passenger weight sensor was triggered. A broken seatbelt may interfere with the sensor. Most cars’ airbag sensors activate when the seatbelt is fastened, with the idea of determining whether an adult is seated on the passenger side. Your car might believe that a seat is occupied and that the light should stay on if any of the seat belts are defective or fail to latch securely. Plug each seat belt in individually to ensure that it clicks before pressing the button to release it while your car is running. Your airbag light can come on because of a defective seat belt. Check the seat belts to ensure that they are working properly. When you open the glove box or passenger door, you will be able to see this button, which is often on the passenger-side dashboard.

It’s possible that someone accidentally turned it off, leaving the airbag light on. When trying to turn off the airbag light, one of the things to check is the passenger seat airbag on/off button, which is only present in some vehicles. Locate and check the passenger airbag switch.
