Impact Sensor: Description and Operation
INFLATABLE RESTRAINT FRONT END DISCRIMINATING SENSOR
The front end discriminating sensor is equipped on some vehicles to supplement SIR system performance. The discriminating sensor is an
electro-mechanical sensor and is not part of the deployment loops, but instead provides an input to the SDM. The SDM uses the input from the
discriminating sensor to assist in determining the severity of a frontal collision further supporting air bag deployment. If the SDM determines a
deployment is warranted, the SDM will cause current to flow through the deployment loops deploying the frontal air bags.
