System Components and Operation: Components: Notes

Name	Major function	Location
Airbag control module	Senses impact and judges its magnitude by means of a safety sensor and G sensor built inside. Serves as supplementary power supply if the battery voltage is lowered for some reason. Directs airbags to inflate. Performs self diagnosis of the airbag system.	Inside center console.
Driver's seat air-bag module	Protects the driver's head and upper body to minimize injury in an event of frontal collision.	Stowed inside the pad at the center of the steering wheel.
Passenger's seat airbag module	Protects the passenger's head and upper body to minimize injury in an event of frontal collision.	Stowed inside the instrument panel at the front passenger's side.
Driver's seat side airbag module	Protects the driver's upper body to minimize injury in an event of side collision.	Stowed inside the driver's seat backrest.
Passenger's seat side airbag module	Protects the front passenger's upper body to minimize injury in an event of side collision.	Stowed inside the front passenger's seat backrest.
Curtain airbag module	Deploys together with the side airbag to protect the driver's or passenger's head and minimize injury in an event of side collision.	Stowed inside at left and right sides from the A pillars through the upper part of C pillars.
Steering roll connector	Provides electrical connection between the vehicle side airbag harness and steering wheel.	Between the combination switch and steering wheel.
Seat belt pretensioner	Retracts the seat belt immediately to restrain the body of front seat passengers in an event of a frontal collision.	Lower part of left and right B pillars.
Front sub sensor	Detects the impact in an event of a frontal collision and outputs a deceleration signal to the control module.	In front of left and right front frames.
Side airbag sensor	Senses impact and judges its magnitude in an event of a side collision by means of a safety sensor and G sensor built inside. Performs self diagnosis of the airbag system.	Inside the left and right B pillars.
Curtain airbag sensor	Senses impact and judges its magnitude in an event of a side collision by means of a safety sensor and G sensor built inside. Performs self diagnosis of the airbag system.	In front of rear left and right wheel arches.
Airbag warning light	Indicates whether the system is normal or abnormal. Displays diagnostic trouble codes.	Inside the combination meter.
Occupant detection control module	Decides whether an adult, child, or is nobody is sitting in the seat, based on the occupant detection sensor output. Performs self diagnosis of the occupant detection system.	Beneath the passenger's seat cushion.
Loadcell sensor	Detects the load on the seat applied by the passenger.	On the passenger's seat slide rail.
Passenger's seat airbag ON/OFF indicator	Indicates whether the deployment of the passenger's seat airbag is allowed or not, based on the decision of the occupant detection system.	Center of the instrument panel at the clock area.
Buckle switch	Detects whether the seat belt is fastened or not.	At the seat belt buckle.
Seat position sensor (LH)	Detects the fore-aft position of the driver's seat and distinguishes the passenger.	On the driver's seat slide rail.
