How the car detects it

The firing circuit for the front passenger airbag in the dashboard is open. While an airbag fault is stored, the affected airbag or pretensioner may not deploy in a crash. Have it repaired before relying on it. Never probe airbag connectors with a meter: that can fire the airbag.
