Side Impact Sensor (SIS)

Description

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