SIDE IMPACT COLLISION SRS OPERATION
When either the driver or passenger side impact side airbag sensor detects a sudden lateral acceleration which
exceeds the lateral threshold value a signal is sent to the ORC. The ORC then deploys the appropriate side airbag.
The SRS electrical circuits are continuously monitored
and controlled by a microprocessor and software con-
tained within the Occupant Restraint Controller (ORC)
(1). An airbag warning indicator lamp in the Instrument
Cluster (IC) illuminates for about six seconds as a
bulb test each time the ignition switch is turned to the
On or Start positions. Following the bulb test, the air-
bag warning indicator lamp is turned On or Off by the
ORC to indicate the status of the SRS. If the airbag
warning indicator lamp comes on at any time other
than during the bulb test, it indicates that there is a
concern in the SRS electrical circuits. Such a problem
may cause airbags to not deploy when required, or to
deploy when not required.
Deployment of the driver and passenger airbags
depends upon the angle and severity of an impact.
Deployment is not based upon vehicle speed; rather,
deployment is based upon the rate of deceleration as
measured by the forces of gravity (G force). When an
impact is severe enough, the microprocessor in the
ORC signals the inflator of the appropriate airbag units to deploy their airbag cushions. The SBT is provided with a
deployment signal by the ORC in conjunction with the driver and passenger airbags. During a frontal vehicle impact,
the seat belts are used to restrain both the driver and the passenger in the proper position for an airbag deploy-
ment. The SBT removes the slack from the seat belts to provide further assurance that the driver and passenger are
properly positioned and restrained for an airbag deployment.
