Side Impact Sensor (Sis): Description
WARNING: This page is about a different car, the 2005 Kia Spectra5, 2005 Kia Spectra, and 2004 Kia Spectra. However, it is still accessible from the selected car via links, so may be relevant.
The Side Impact Sensor (SIS) system consist of two front SIS which are installed inside the B-Pillar (LH and RH) and two rear SIS which are installed in the C-Pillar (LH and RH). They are remote sensor that detect acceleration due to collision at their mounting locations. The primary purpose of the Side Impact Sensor (SIS) is to provide an indication of a collision earlier than is possible from a central mounting location. The Side Impact Sensor (SIS) sends acceleration data to the SRSCM.
