Weight Sensors
Your vehicle has four Weight Sensors located between
the seat and the floor pan. The weight sensors measure
applied weight and transfers that information to the
OCM.
Supplemental Side Seat Airbag Inflator Units — If
Equipped
The Side Impact (SRS) Seat-Mounted Side Airbags are
designed to activate only in certain side collisions.
The ORC determines if a side collision requires the side
airbags to inflate based on the severity and type of
collision.
The ORC monitors the readiness of the electronic parts of
the system whenever the ignition switch is in the START
or ON positions. These include all of the items previously
mentioned.
Based on the severity and type of collision, the side
airbag inflator on the crash side of the vehicle may be
triggered, releasing a quantity of non-toxic gas. The
inflating side airbag exits through the seat seam into the
space between the occupant and the door. The side
airbags fully inflate in about 10 milliseconds. The side
airbag moves at a very high speed and with such a high
force, that it could injure you if you are not seated
properly, or if items are positioned in the area where the
side airbag inflates. This especially applies to children.
Because airbag sensors estimate deceleration over time,
vehicle speed and damage are not good indicators of
whether or not an airbag should have deployed.
Front and Side Impact Sensors
In front and side impacts, impact sensors aid the ORC in
determining appropriate response to impact events. Ad-
ditional sensors in the ORC determine the level of airbag
deployment and provide verification.
