SRS EXTERNAL SENSORS
When an impact event occurs, the SRSCM calculates
whether or not the front airbags should be deployed
and determines what the deployment timing should
be. This deployment decision occurs after the SRSCM
compares the Crash Severity Level from the FIS and
the signal from the internal Acceleration sensor.
FRONT IMPACT SENSOR
(FIS) COMPONENT
The FIS is a remote intelligent acceleration sensor
located in the centerline of the Spectra, just behind
the radiator support near the radiator cap. The FIS
provides the secondary accelerometer data to the
advanced restraint control module to determine if the
severity of a frontal impact event warrants a single-
stage or dual-stage frontal airbag deployment.
