Description and Operation: Description

Side Impact Sensor (SIS) system consists of two Front-SIS which are installed at each center of the front door module (LH and RH) and two Rear-SIS which are installed at each rear pillar nearby (LH and RH). Front-Side Impact Sensor (F-SIS) is also called P-SIS because that detects pressure due to collision at its mounting location.

Rear-Side Impact Sensor (R-SIS) is also called A-SIS because that detects acceleration.

SRSCM decides deployment or not of the airbag and the time of deployment through the collision signal of SIS when the collision occurred.
