DANGER
The SRS-ECU adopts the rollover specifica-
tion that the curtain airbag and seat belt
pre-tensioner operate at the occurrence of
rollover. Therefore, do not tilt the vehicle to
the right and left with the IG ON or tilt the
SRS-ECU to the right and left with the IG ON
and the harness installed.
.
WARNING
Improper service could result in serious
injury of the service personnel or the pas-
senger.
.
The SRS is designed to supplement the front seat
belts. It reduces injury to the driver(s) and the front
passenger(s) by deploying air bag(s) in case of a
frontal collision. In addition, the side-airbag and cur-
tain air bag inflate upon a side collision to reduce the
risk of passenger injuries.
The SRS front air bags from an advanced air bag
system together with sensors at the vehicle and sen-
sors attached to front seats.
.
Side-airbag systems in the front seats are activated
when side impacts exceed a criteria to protect the
occupants’ upper bodies.
.
The curtain airbag system operates together with the
side-airbag to protect the heads of passengers in the
front and second seats.
.
The seat belts with pre-tensioner work simulta-
neously with the SRS. The seat belt incorporating the
pre-tensioner automatically winds the seat belt upon
front impact to reduce forward shifting of the driver’s
and passenger’s. The seat belt use status is used to
control the activation and deactivation of the pre-ten-

sioner. In addition to the pre-tensioner for the shoul-
der side, the lap pre-tensioner has been installed on
the outer seat belt lower anchor side of the driver's
seat in order to improve the restraining performance
around the waist as well as the chest area.
.
The SRS consists of air bag modules, SRS air bag
control unit (SRS-ECU), front impact sensors, side
impact sensors, SRS warning light, passenger’s air
bag OFF indicator light, passenger’s seat belt warn-
ing light, clock spring, seat belt pre-tensioner, seat
belt switch, seat slide sensor, weight sensor and
occupant classification-ECU. Air bag modules are
located in the center of the steering wheel and above
the glove box. Side-airbags are located inside the
front seatback assemblies. The curtain air bag mod-
ule 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 passen-
ger's front pillars to the rear pillars). Each air bag
consists of a folded air bag and an inflator unit. The
SRS-ECU placed on the forefront of the floor moni-
tors the system and has a front air bag safing G-sen-
sor, front air bag analog G-sensor and a side-airbag
safing G-sensor. The front impact sensor is assem-
bled in the front end upper bar to monitor impact in
case of front impact. The side impact sensors inside
the center pillars and the rear quarter panel monitor
the shock incurred by the sides of the vehicle. The
SRS warning light on the combination meter indi-
cates the operational status of the SRS. The clock
spring is installed in the steering column. The seat
belt pre-tensioner is built into the driver's and pas-
senger's front seat belt retractor. The seat slide sen-
sor is installed at the seat adjuster section of the
driver seat in order to detect the driver seat slide
position. The weight sensor is installed underneath a
rail of the passenger seat to detect the load on the
seat. The passenger’s air bag OFF indicator light is
installed to the lower left of the center panel, and illu-
minates when the passenger seat airbag is inactive.
The passenger’s seat belt warning light is installed to
the lower right of the center panel, and illuminates
when the passenger is not wearing the seat belt. The
seat belt switch detects whether the seat belt is
used.
Only authorized service personnel should do work on
or around the SRS components. Those service per-
sonnel should read this manual carefully before start-
ing any such work.
.
ON-BOARD DIAGNOSTIC/SRS WARNING LIGHT
FUNCTION
The SRS-ECU monitors the SRS system and stores data con-
cerning any detected faults in the system. When the ignition
switch is in "ON" position, the SRS warning light, passenger’s
air bag OFF indicator light and passenger’s seat belt warning
light should illuminate for about seven seconds and then turn
"OFF." That indicates that the SRS system is in operational
order. If the SRS warning light does any of the following, the
immediate inspection by an authorized dealer is needed:
1. The SRS warning light does not illuminate as described
above.
2. The SRS warning light stays on for more than seven
seconds.
3. The SRS warning light illuminates while driving.
If a vehicle's SRS warning light is in any of these three condi-
tions, the SRS system must be inspected, diagnosed and ser-
viced in accordance with this manual.
