Almost all of the new cars and trucks today are using airbags.  These airbags can be located in the driver steering and the passenger’s airbag is located in the dashboard.  Once the sensor is triggered by an impact the airbag will be deployed.  After deployment, you need to Re-set the Airbag Control Module.  The airbag control module serves as the brain of the airbag.  If you will not reset the airbag control module it will become unusable.  To make it functionable again it needs the resetting process.  Mechanics can reset the airbag control module of all major brands of cars and trucks.
