Airbag Sensor Assembly |
|
Occupant Detection ECU |
Determines front passenger seat occupant conditions through occupant classification sensors |
Front Airbag Sensor |
Detect intensity of frontal collisions though electrical deceleration sensor |
Side Airbag Sensor Assembly |
Detect intensity of side collision through electrical deceleration sensor |
Rear Airbag Sensor |
Detect intensity of side rear collision through electrical deceleration sensor |
Occupant Classification Sensors |
Detect occupant weight on front passenger seat |
Seat Position Airbag Sensor |
Detects driver seat position |
Seat Belt Buckle Switches |
Detect whether of not seat belt fastened |
Airbag ON/OFF Indicator |
Illuminates ON or OFF light to indicate front and side passenger airbag deployment availability |
SRS Warning Light |
Illuminates to indicate existence of malfunctions in SRS airbag system |
2. AIRBAG DEPLOYMENT
(a) Front Collisions
(1) The driver and front passenger airbags are in case of frontal collisions. These airbags deploy by dual stage control. In order to activate dual stage control, the airbag sensor assembly monitors the following information through the components shown in the table below:

(b) Side Collisions
(1) The side and curtain shield airbags are in case of side collisions. The side airbags are installed in the seat backs of the driver seat and the front passenger seat, and the curtain shield airbags are installed in the upper areas of the right and left center pillars. If a side airbag sensor assembly detects an impact, the airbag sensor assembly causes the side and curtain shield airbags to be deployed simultaneously.
(c) Rear Side Collisions
(1) The side and curtain shield airbags are in case of rear side collisions. The side airbags are installed in the seat backs of the driver seat and the front passenger seat, and the curtain shield airbags are installed in the upper areas of the right and left center pillars. If a side airbag sensor assembly detects an impact, the airbag sensor assembly causes the side and curtain shield airbags to be deployed simultaneously.
