SIDE AND CURTAIN AIR BAGS

M2521000800573

SRS-ECU uses data of the side impact sensor and
G-sensor (in SRS-ECU) to calculate collision sever-
ity, during side collision. SRS-ECU judges necessity
of side-airbag and curtain air bag based on the cal-
culated collision severity.

The airbag module is equipped with an inflator that
does not contain sodium azide.

The air bag is made of nylon and is inflated by the
gas from the inflator. Then, as the air bag contacts
the passenger, the gas is discharged through two
openings of backside of air bag, thus deflating the air
bag to reduce the impact on the passenger.

PASSENGER'S (FRONT) AIR BAG MODULE

M2521003000628

The passenger’s (front) air bag module consists of
an air bag, and their fasteners.
The air bag is made from nylon and inflates by the
gas from the inflator. As a passenger is being
pressed to the air bag, it deflates, discharging gas
from two vents at the side of the air bag to reduce the
shock from the impact.

For the inflator, the gas which is harmless to the
human body has been used.

KNEE AIR BAG MODULE

M2521002600177

The knee air bag module consists of a cover, an air
bag, an inflator, and the fixing gear relating to those
parts, and is installed under the steering column.

Like the driver's and front passenger's air bags, the
knee air bag is inflated upon a frontal collision for
better protection of the driver.

SIDE-AIRBAG MODULE

M2521004000557

The side-airbag module consists of an air bag, air
bag cover, inflator and their fasteners. The modules
are installed in the outer side supports of the driver’s
and front passenger’s seatbacks. The side-airbags
help protect the occupants regardless of the seat
position and seatback angle.

The air bags are compactly folded and stored under
the cover. On the side of the air bag, there are holes
through which gas is partially released to alleviate
shock to the occupant when the air bag is deployed.
For the inflator, the gas which is harmless to the
human body has been used.

52B-11

The curtain air bag module consists of an air bag, an
inflator, and the fixing gear relating to those parts,
and is installed in the roof side sections (from the
driver's and the passenger's front pillars to the rear
pillars).
An inflator that does not contain sodium azide is
used.

FRONT IMPACT SENSOR

M2521005000646

• The front impact sensor is installed on the head-

lamp support panel upper in the engine room,
and the analogue G-sensor is housed in the front
impact sensor.

• The front impact sensor transmits the coded

acceleration data to SRS-ECU. Based on the
data, SRS-ECU determines the deployment
stage of the front air bag, then energises appro-
priate squib.

• SRS-ECU performs the diagnostics of the front

impact sensor internal components. If a malfunc-
tion occurs, it sets the diagnosis code.

SIDE IMPACT SENSOR

M2521006000575

• The side impact sensors are installed to the lower

part of the centre pillars on both sides, and the
analogue G-sensor is housed in the side impact
sensor.

• The front impact sensor transmits the coded

acceleration data to SRS-ECU. Based on the
data, SRS-ECU determines the deployment of
the side-airbags and curtain air bags, then ener-
gises appropriate squib(s).

• SRS-ECU performs the diagnostics of the side

impact sensor internal components. If a malfunc-
tion occurs, it sets the diagnosis code.
