SRS 7 10.2.7 FRONT REMOTE SENSING UNIT (RSU) OR FRONT IMPACT SENSOR The front RSU’s are used for early sensing & severity discrimination of frontal 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 on the RH and LH crash member top surface behind the front end module.
