SRS AIR BAG SYSTEM
FUNCTION DIAGNOSIS
SRS AIR BAG SYSTEM
SRS Configuration
INFOID:0000000001277709
The air bag deploys if the air bag diagnosis sensor unit is activated while the ignition switch is in the ON or
START position.
The collision modes for which supplemental restraint systems are activated are different among the SRS sys-
tems. For example, the driver air bag module, front passenger air bag module and front seat belt pre-tension-
ers are activated in a frontal collision but not in a side collision.
SRS configurations for some collision modes are as follows:

SRS AIR BAG SYSTEM
Front Passenger Air Bag Module
INFOID:0000000001277783
The front passenger air bag module is located behind the instrument
panel assembly. It operates with the SRS system in a frontal colli-
sion exceeding a specified level. Refer to
for more information.
Front Side Air Bag
INFOID:0000000001277713
Front side air bag modules are built into the front seatback assem-
blies. Vehicles with side air bags are equipped with labels as shown.
Side Curtain Air Bag
INFOID:0000000001277714
Side curtain air bag modules are located above the vehicle headlining.
Vehicles with side curtain air bags are equipped with labels as
shown.
Front Seat Belt Pre-tensioner with Load Limiter
INFOID:0000000001277784
The seat belt pre-tensioner system with load limiter is installed for
both the driver's seat and the front passenger's seat. It operates
simultaneously with the SRS air bag system in the event of a frontal
collision with an impact exceeding a specified level.
When the frontal collision with an impact exceeding a specified level
occurs, seat belt slack resulting from clothing or other factors is
immediately taken up by the pre-tensioner. Vehicle passengers are
securely restrained.
When passengers in a vehicle are thrown forward in a collision and
the restraining force of the seat belt exceeds a specified level, the
load limiter permits the specified extension of the seat belt by the
twisting of the ELR shaft, and a relaxation of the chest-area seat belt
web tension while maintaining force.
