WARNING: This page is about a different car, the 2018 Hyundai Accent. However, it is still accessible from the selected car via links, so may be relevant.
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 it detects pressure due to collision at its mounting location.
Side Impact Sensor is also called A-SIS because it detects acceleration.
SRSCM decides deployment of the airbag and the time of deployment through the collision signal of the SIS when the collision occurred.
