1.The Side Impact Sensor (SIS) system consists of two kinds of side impact sensor which are installed at each center of the front door module (left and right) and two rear sensors which are installed in the rear pillar (left and right).
• The Front Side Impact Sensor is also called P-SIS because it detects pressure due to collision at its mounting location.
• The Rear Side Impact Sensor is also called A-SIS because it detects acceleration due to collision at its mounting location.
SRSCM decides deployment of the airbag and the time of deployment through the collision signal of the SIS when collision occurrs.
