Vehicle Collision Diagnostics
Whether the airbag is deployed or not, vehicle collision diagnostic and maintenance must be conducted
according to the following procedures.
1. Check the SRS-ECU diagnostic signal
(a) Connect the diagnostic connector (X-431 diagnostic scanner).
(b) Read the diagnostic result with the X-431 diagnostic.
Caution: Due to impact, and when the battery's power supply is insufficient, the scanner will be unable
to communicate with the SRS-ECU. At this time, use an external power supply, or make sure to
perform inspection and maintenance on the dashboard's wire harness.
2. Maintenance sequence
When the airbag is deployed, the following components should be replaced\
.
(a) Driver side airbag module.
(b) Front passenger side airbag module.
(c) SRS-ECU.
(d) Driver side and front passenger side preload seat belts.
Inspect the following components, if anything is abnormal, replace with \
a new one.
(a) Clock spring.
(b) Steering wheel, steering column, and steering lower shaft components.
Installation status of the driver side airbag module regarding the steer\
ing wheel.
(a) Inspect whether the steering wheel's noise is abnormal, for improper movement, or abnormal cleara\
nce.
(b) Inspect whether the wire harness connectors are broken and whether the terminals are deformed.
3. SRS-ECU
(a) Inspect whether the SRS-ECU housing and bracket are
sunken or depressed, cracked, deformed, etc.
(b) Inspect for broken connectors as well as deformed
terminals.
(c) Inspect the SRS-ECU bracket's installation status.
• Inspect whether the cover is sunken or depressed,
cracked, deformed, etc.
• Inspect for broken connectors as well as deformed
terminals and biting wire harnesses.
• Check whether the gas generator's housing is sunken or
depressed, cracked, deformed, etc.
• Inspect whether the arrow's direction is pointed towards
the front of the vehicle.
(d) Inspect the airbag module's installation status.
4. Inspect the driver side airbag module
5. Clock spring
(a) Inspect for broken connectors and protective tube and deformed terminals.
(b) Inspect for deformed housing.
6. Steering wheel, steering column, and lower shaft components
(a) Inspect the driver side airbag module's installation status.
(b) Inspect the steering wheel for abnormal noise, and whether the clearance is normal.
7. Inspect the wire harness connectors (dashboard wire harness).
8. Inspect whether the wire harnesses are firm. Check for damaged connectors, and deformed terminals.
Warning label
The driver side, clock spring, SRS-ECU, and front passenger side airbag, all have warning labels, with the
caution areas shown by an image. While maintenaning and using the SRS airbag, please work in accordance
with the label.Furthermore, when a label becomes damaged or dirty, please replace it with a new one.

Driver Side Airbag Module (DAB), Front Passenger Side Air-
bag Module (PAB), Clock Spring, and Steering Wheel
Areas of Importance
1. Take off the battery's negative (-) terminal, and wait for 60 s before operating. Wrap the removed
negative (-) terminal in tape to insulate it.
2. The airbag module and clock spring must not be dismantled or repaired. If there is any malfunction,
replace the part.
3. Pay attention to the usage of the airbag module and clock spring. Do not drop it or immerge it in water
or oil. Furthermore, if there is any sinking or depression, cracking, deformity, etc., please replace it
with a new part.
4. Make sure the extended surface is faced upwards when the airbag module is to be deployed. Put it on
a flat surface and do not place anything on top of it.
5. Do not put the airbag module in a place where the temperature is over 93\
oC.
6. After the airbag module is deployed, replace it with a new one. At the same time, inspect the clock
spring (contact resistance between corresponding terminals should not be more than 0.8 Ω). If there
is anything abnormal, replace it with a new one.
7. Use gloves and protective glasses while operating on a deployed airbag.
8. While scraping an undeployed airbag, make sure to discard it after it ha\
s been deployed first.
9. During removal, to avoid experiencing static electricity interference leading to faulty execution, make
sure to remove the other wire harness connectors after the DAB and PAB module wire harness
connectors have been removed. Installation is done in reverse order.

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
