AIRBAG SYSTEM
OPERATING SEQUENCE
8
This drawing illustrates the operational and airbag
deployment sequence:
• The SRS advises the driver of its operating
condition through the Service Reminder
Indicator (SRI)
• When a frontal, near frontal or side impact event
occurs, it is detected by internal and external
sensors to deploy airbags.
- Front and/or Side impact sensors
- Safing sensor
- Accelerometer
One sensor alone cannot deploy airbags.
• Deployment or No Deployment decision is made by
the crash algorithm
• If there is a Deployment decision by the SRSCM:
- The Inflator ignites
- A gas such as Nitrogen is produced to inflate bag
- Bag(s) deploy
• After deployment, the airbag(s) vents/deflates
• The SRSCM determines Belt Pretensioner
deployment
• SRS event data is recorded
• SRSCM signals the Power Window Main Switch to
unlock doors
