Front End Sensor

INFLATABLE RESTRAINT FRONT END SENSOR

The front end sensor is equipped on some vehicles to supplement SIR system performance. The front end sensor is an electro-mechanical sensor and is not part of the deployment loops, but instead provides an input to the sensing and diagnostic module (SDM). The SDM uses the input from the front end 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.
