Areas of Importance
1. While performing maintenance on the SRS airbag, make sure to work in accordance with this
chapter's steps and notes.
2. Be sure to use the specified test apparatus and SST (Special Service Tools) which are mentioned in this
chapter.
3. While performing maintenance on the following mentioned components, if there is any problem with a
component, be sure to replace it with a new one.
• Airbag ECU assembly.
• Clock spring assembly.
• Driver side airbag assembly.
• Front passenger side airbag module.
• Driver side preload seat belt.
• Front passenger side preload seat belt.
• Airbag wire harness.
4. While performing maintenance, please disconnect the battery's negative terminal connector, and then
after waiting for 60 s, commence operation. Furthermore, wrap up the removed negative terminal with
insulating tape.
After the battery power is cut off, the capacitor in the airbag ECU will still maintain a set amount of electrical
energy. If used without waiting a sufficient amount of time, it may lead to serious injury and accidents due to
the airbag's faulty deployment.
5. When painting the vehicle, excessive heat may influence the components, in which case the SRS-ECU,
airbag module, clock spring, etc., should first be removed and set aside\
.
Use a diagnostic scanner to clear the trouble code after the SRS airbag is repaired, as to ensure the warning
lamp will continue to work normaly.

Alignment area
(a) Whether there are broken connectors or protective
pipes and deformed terminals.
(b) Whether the housing is damaged.
(c) Inspect whether the clock spring's upper connector
terminal and lower corresponding connector terminal is
conducting.
Clock spring central involution
Screw in the clock spring clockwise all the way, and then
turn it 3.5 circles in the reverse direction, until the position
pin's block boss matches the block hole (as shown on the
left).
Caution: If the clock spring is not in the involution
central, the steering wheel will be unable to rotate
midway or cause clock spring circuit failure, which will
obstruct the normal operation of the SRS airbag.
6. Steering wheel and airbag module subassembly installation
(a) After pulling out the clock spring's position pin, install the steering wheel and airbag module su\
bassembly.
Caution: While installing the steering wheel and airbag module subassembly, please do not block the
clock spring wire harness.
(b) After installation, try to turn the steering wheel left and right to its proper position, and check for anything
abnormal.
7. Inspection after installation
(a) Lightly turn the steering wheel left and right to check whether there is anything abnormal or for any
strange noise. (Driver side airbag module, clock spring).
(b) Set the ignition switch to the ON position.
(c) The SRS warning lamp will remain on for 6-7 s and will then die out.
(d) If the warning lamp is always on or shows other symptoms after 6-7 s, troubleshooting must be perf\
ormed.
(e) Inspect whether the clock spring circuit is open circuited. If yes, please replace it with a new \
one.
(f) If no, check the other circuits.
Airbag Module Disposal
While discarding the airbag module or a vehicle carrying a SRS airbag, please discard according to the following
steps.
Discarding essentials of the airbag module before deployment
1. Deploy the airbag before discarding SRS airbag.
2. Deploy the airbag outside the vehicle when replacing the airbag module.
3. There may be some smoke when deploying the airbag, so make sure to operate near a smoke
detector.
4. When deploying the airbag, the sound will be very loud. Please ask nearby people to plug their ears,
and try not to operate near residential areas.
Airbag deployment
Wa r n i n g : T h e f o l l o w i n g s t e p s c a n p r e v e n t s t a t i c
electricity trigged accidental deployment, so please
carefully follow them.
1. Park the vehicle on a flat surface.
2. D i s c o n n e c t t h e b a t t e r y ' s n e g a t i v e a n d p o s i t i v e
terminals, and remove the battery from the car.
Caution: Avoid wearing apparel which may generate
friction due to electricity. Disconnect the battery's
p o s i t i v e a n d n e g a t i v e t e r m i n a l s , a n d c o m m e n c e

Wi r e h a r n e s s u s e d for deployment
Old tire with no hub
Wire harness used for deployment
Wire harness used for deployment
Wire harness used for deploymentShort circuit area
Longer than 6 m
4. Deploy the wire harness after removing the No. 2
connector of the clock spring.
Prepare two wire harnesses longer than 6 m for deployment,
and connect one of their ends together (to short circuit).
Caution: When deploying the airbag, make sure to
maintain a distance of at least 6 m away from objects
or people, and perform the deployment on a flat sur-
face. While deploying the airbag module outdoors,
avoid strong winds, and ignite it against the wind.
8. Place three old tires with no hub on the tires which are
used to fix in place the driver side airbag module (shown
on the left).
9. Cut off the connection of the driver side airbag module's
wire harness which is used for deployment at a place as
far away from the vehicle as possible and connect it to
the two terminals removed from the vehicle battery, caus-
ing it to deploy (shown on the left).
Caution: Deploy it only after ensuring that there are no
people around the airbag module. After the deployment
of driver side airbag module, the gas generator will be ex-
tremely hot. Continue to use it only after 30 min cooling.
10. Discard the deployed driver side airbag module accord-
ing to the discarding essentials.
5. Insert the airbag deployment wire harness into the
airbag execution device.
6. Install the unused bolts on the driver side airbag
module's inner side bolts, and bound the wheel rim with
a thick metal wire, so as to set the wheel rim in place.
7. Connect the wire harness used for deployment which is
connected with the driver side airbag module with the
lower part of the old tire which is used for installing the
wheel rim. Upwardly fix the driver side airbag module
with the metal wire which is connected to the bolt
(shown on the left).
