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

Removal Method for Individual Components
SRS airbag system electronic control component (SRS-ECU)
1. Areas of Importance
(a) After taking off the battery's negative (-) terminal, wait for 60 s before operating. Wrap the removed
negative (-) terminal in tape to insulate it.
(b) The SRS-ECU can not be dismantled or repaired. If there is any malfunction, please replace it with a new
one.
(c) Do not let the SRS-ECU vibrate or collide with anything. If sunken or depressed, cracked, deformed, etc.,
please replace with a new SRS-ECU.
(d) Every time the airbag is deployed, please replace with a new SRS-ECU.
(e) Do not knock the SRS-ECU while removing or performing maintenance on the SRS-ECU's surrounding
components.
2. Operation before removal
(a) Set the ignition switch to the LOCK position.
(b) After taking off the battery's negative (-) terminal, put them in a proper place or wrap them in\
tape.
3. Removal sequence
(a) Remove the auxiliary facia console.
(b) Reomve the connectors connected with the airbag ECU.
(c) Remove the SRS-ECU.
4. Installation sequence
(a) SRS-ECU.
(b) Install the connectors connected with the airbag ECU.
(c) Dashboard base.

5. Installation points
(a) Install the SRS-ECU
Caution: If SRS-ECU isn't installed correctly, the SRS airbag will not operate properly.
(b) Inspection after installation
• Set the ignition switch to the ON position.
• SRS warning lamp stays on for 6-7 s.
• If the lamp does not turn off, malfunction inspection and troubleshooting should be performed.
6. Inspection
(a) Whether the SRS-ECU cover has sunken or depressed, cracked, deformed, etc.
(b) Whether the connectors are damaged or deformed.
Caution: Please replace with a new SRS-ECU, if there is any sunkeness or depression, cracking, de-
formity, etc.
Except for the areas described above, to perform SRS-ECU inspections, please refer to the related troubleshooting
contents.

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.
