Kia Optima: SRSCM / Front Impact Sensor (FIS)
Description and operation
The front impact sensor (FIS) is installed in the Front End Module (FEM). They
are remote sensors that detect acceleration due to a collision at its mounting location.
The primary purpose of the Front Impact Sensor (FIS) is to provide an indication
of a collision. The Front Impact Sensor (FIS) sends acceleration data to the SRSCM.
