Side Impact Sensor (SIS) system consists of two P-SIS, installed at each center of front door modules (LH and RH), and two SIS, installed at each center of nearby pillars (LH and RH).
P-SIS or Pressure Side Impact Sensor detects pressure due to collision at its mounting location.
Side Impact Sensor is also called A-SIS as it detects acceleration.
SRSCM determines the deployment of airbag and the time of deployment based on the collision signal from the SIS at the time of collision.
