AIR BAG SYSTEM OUTLINE

E5U081000000N01

• The air bag system is a device that supplements the passenger restraint function of the seat belts. The air bag

system will not have the designed effect if the seat belts are not worn properly.

• The air bag system is composed of the following parts:

Item

Outline

SAS control module

• Two-step deployment control has been added to the front air

bag system (driver and passenger-side) deployment control.

• Recognizes actually equipped air bag module or pre-

tensioner seat belt based on module configuration.

Crash zone sensor

• Detects degree of impact, converts to an electrical signal, and

sends the signal to the SAS control module. For operation,
refer to SAS control module, Air Bag Module and Pre-
tensioner Buckle Deployment Operation. (See 08–10–5 SAS
CONTROL MODULE CONSTRUCTION/OPERATION)

Side air bag sensor

Driver-side air bag module

• Dual inflators, inflator 1 and inflator 2, have been adopted in

accordance with the front air bag system two-step
deployment control.

Passenger-side air bag module

Side air bag module

• The side air bag module with a head-protection function has

been adopted to soften the impact during a collision to the
side of the vehicle.

Pre-tensioner seat belt

• Piston-type pre-tensioner seat belt has been adopted.

Seat track position sensor

• Detects the seat track position of the driver’s seat, and sends

a corresponding signal to the SAS control module.

PAD switch

• PAD switch has been adopted enabling optional deactivation

of passenger-side air bag module, passenger-side side air
bag module, and passenger-side pre-tensioner seat belt.

PAD indicator

• PAD indicator has been adopted to inform driver and

passenger of the deployment standby status of the
passenger-side air bag module, passenger-side side air bag
module, and passenger-side pre-tensioner seat belt.

Air bag system warning light

• LED has been adopted.

Seat belt warning light

Seat weight sensor

• Measures the compression weight of the load applied to the

passenger-side seat by the distortion amount using two seat
weight sensor and sends an electrical signal corresponding to
the distortion amount to the seat weight sensor control
module.

Seat weight sensor control module

• Based on the electrical signal sent from the seat weight

sensor corresponding to the distortion amount, calculates the
total seated weight to determine the passenger, and sends
the determination result to the SAS control module.
