SRS 8 10.2.8 SIDE REMOTE SENSING UNIT (RSU) OR SIDE IMPACT SENSOR (IF FITTED) The side RSU’s are used for early sensing & severity discrimination of side crash modes. They send signals to the SRS ECU and help in firing the restraints at the optimal time in a frontal crash. They also provide “Safing” function to ensure that the SRS fires only when there is a physical crash event of significant severity. They are located inside the front RH B - pillar and front LH B - pillar.
