|
| • |
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

|
| • |
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 or front 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 and the front impact sensors. The airbags could accidentally
deploy and cause damage or injury.
|
| • |
Replace the front airbag module, SRSCM, FIS when the front airbag
is deployed. 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, the front impact sensor and/or the side impact sensors.
|
| • |
Do not disassemble the SRS unit, the front impact sensor or 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, the front impact sensor and side impact
sensors are installed securely with the mounting bolts.
|
| • |
Do not spill water or oil on the SRS unit, or the front impact
sensor or the side impact sensors and keep them away from dust.
|
| • |
Store the SRS unit, the front impact sensor 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.
