DeVille DHS V8-4.6L VIN Y (2000)
Impact Sensor: Description and Operation
Inflatable Restraint Side Impact Sensor
The inflatable restraint Side Impact Sensor (SIS) performs the following functions in the air bag system:
^
Side Impact Crash Detection-Each SIS monitors vehicle acceleration and velocity changes to detect side impact crashes that are severe enough to
warrant deployment.
^
Side Impact Air Bag Deployment-During a side impact crash of sufficient force, the SDM will send enough current to flow through the respective
side to deploy the side impact air bag.
The SIS connects to the SDM using a 2-way connector.
The driver and passenger SIS modules are treated as a discriminating sensor in frontal deployments.
