When does an airbag module have to be replaced?

An airbag module typically needs to be replaced after a vehicle has been involved in a collision that triggered the airbag deployment, as it can no longer function properly. Additionally, if the airbag warning light remains illuminated on the dashboard, this may indicate a malfunction or fault in the airbag system that requires replacement. Regular inspections and maintenance are also essential for ensuring the airbag system is in good working condition.
