Safing Sensor: Description and Operation

The sensor is an electrical switch which reacts to impacts according to direction and force. It discriminates between impacts that require air bag inflation and impacts that do not require air bag inflation. When an impact occurs that requires air bag inflation, the sensor contacts close, completing the electrical circuit necessary for system operation.

Five sensors are mounted in the vehicle. Their locations are as follows:
- A dual crash and safing sensor at the radiator support.
- A crash sensor at the RH fender apron.
- A crash sensor at the LH fender apron.
- A safing sensor at the cowl in the passenger compartment.

At least two sensors, one safing, one front, must be activated to inflate the air bag.
