Discriminating Sensors and Arming Sensors: Description and Operation
DESCRIPTION
The discriminating and arming sensors are used by the SIR system to determine whether or not certain frontal crashes require deployment of the air
bags.
OPERATION
The sensor consists of a sensing element, normally open switch contacts and a diagnostic resistor. The sensing element closes the switch contacts when
the vehicle velocity changes are severe enough to warrant air bag deployment.
