Loose connections can also cause the airbag light to activate. Wires connecting various components of the airbag system may become loose over time. This often happens after service or maintenance. A common example is the seatbelt sensor connection. Ensuring all connections are secure can resolve the issue. If you identify a loose connection, reconnect it firmly. If the light persists, a professional inspection is recommended.
