Impact Sensor: Description and Operation
Side Impact Sensor (SIS)
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.
