Please read the
following precautions carefully before performing the airbag system
service.
Observe the instructions
described in this manual, or the airbags could accidentally deploy and
cause damage or injuries.
| • |
Except when performing electrical inspections,
always turn the ignition switch OFF and disconnect the negative
cable from the battery, and wait at least three minutes before
beginning work. |
|
The contents in the memory are not erased even
if the ignition switch is turned OFF or the battery cables are
disconnected from the battery. |
| • |
Use the replacement parts which are
manufactured to the same standards as the original parts and
quality.
Do not install used SRS parts from another
vehicle. Use only new parts when making SRS
repairs. |
| • |
Carefully inspect any SRS part before you
install it. Do not install any part that shows signs of being
dropped or improperly handled, such as dents, cracks or
deformation.
|
| • |
Before removing any of the SRSCM parts
(including the disconnection of the connectors), always disconnect
the SRSCM connector. |
Airbag Handling and Storage
Do not disassemble the
airbags; it has no serviceable parts. Once an airbag has been deployed, it
cannot be repaired or reused.
For temporary storage of
the air bag during service, please observe the following
precautions.
| • |
Store the removed airbag with the pad surface
up. |
| • |
Keep free from any oil, grease, detergent, or
water to prevent damage to the airbag assembly.
|
| • |
Store the removed airbag on secure, flat
surface away from any high heat source (exceeding 85 C/185
F). |
| • |
Never perform electrical inspections to the
airbags, such as measuring
resistance. |
| • |
Do not position yourself in front of the
airbag assembly during removal, inspection, or
replacement. |
| • |
Refer to the scrapping procedures for disposal
of the damaged airbag. |
| • |
Be careful not to bump or impact the SRS unit
or the side impact sensors whenever the ignition switch is ON, wait
at least three minutes after the ignition switch is turned OFF
before begin work. |
| • |
During installation or replacement, be careful
not to bump (by impact wrench, hammer, etc.) the area around the SRS
unit and the side impact sensor. The airbags could accidentally
deploy and cause damage or injury. |
| • |
Replace the front airbag module, SRSCM, FIS
when deploying the front airbag. Replace the airbag wiring when the
airbag wiring get damaged. Replace the side airbag module, the
curtain airbag module, SRSCM, SIS when deploying the side airbag.
Replace the airbag when the airbag wiring get
damaged. |
| • |
After a collision in which the airbags or the
side air bags did not deploy, inspect for any damage or any
deformation on the SRS unit and the side impact sensors. If there is
any damage, replace the SRS unit and the side impact
sensors. |
| • |
Do not disassemble the SRS unit and the side
impact sensors. |
| • |
Turn the ignition switch OFF, disconnect the
battery negative cable and wait at least three minutes before
beginning installation or replacement of the SRS
unit. |
| • |
Be sure the SRS unit and the side impact
sensors are installed securely with the mounting
bolts. |
| • |
Do not spill water or oil on the SRS unit or
the side impact sensors and keep them away from
dust. |
| • |
Store the SRS unit and the side impact sensors
in a cool (15 ~ 25 C/ 59 ~ 77 F) and dry (30 ~ 80% relative
humidity, no moisture) area. |
Wiring Precautions
SRS wiring can be
identified by special yellow outer covering Observe the instructions
described in this section.
| • |
Never attempt to modify, splice, or repair SRS
wiring. If there is an open or damage in SRS wiring, replace the
harness.
|
| • |
Be sure to install the harness wires so that
they are not pinched, or interfere with other parts.
|
| • |
Make sure all SRS ground locations are clean,
and grounds are securely fastened for optimum metal-to-metal
contact. Poor grounding can cause intermittent problems that are
difficult to diagnose. |
Precautions for Electrical Inspections
| • |
When using electrical test equipment, insert
the probe of the tester into the wire side of the
connector.
Do not insert the probe of the tester into the
terminal side of the connector, and do not tamper with the
connector.
|
| • |
Use a u-shaped probe. Do not insert the probe
forcibly. |
| • |
Use specified service connectors for
troubleshooting.
Using improper tools could cause an error in
inspection due to poor metal
contact. |
Spring-laded Lock Connector
Some SRS system
connectors have a spring-loaded lock.
Airbag Connector
To release the lock,
pull the spring-loaded sleeve (A) and the slider (B), while holding the
opposite half of the connector.
Pull the connector
halves apart. Be sure to pull on the sleeve and not on the connector
half.
Hold both connector
halves and press firmly until the projection(C) of the sleeve-side
connector clicks to lock.
