Safing Sensor: Description and Operation

PURPOSE
The safing sensor is used to prevent inadvertent deployments possibly caused by a malfunction in the primary crash sensor circuits or crash sensors.

OPERATION
The safing and one of the primary crash sensors must be activated simultaneously to inflate the air bag. When a primary and safing sensor are closed at the same time, electrical current will flow and ignite the driver side air bag module and passenger side air bag module.

LOCATION
The safing sensor is located inside the air bag diagnostic monitor and is not serviceable. The air bag diagnostic monitor must be replaced as a unit in the event of a failure.
