Precautions |
General Precautions |
• |
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 to 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 only the replacement parts manufactured to the same
standards and quality as the original parts.Do not reuse SRS parts
removed from other vehicles. Use only new parts when repairing the SRS.
Do not install used SRS parts from another vehicle. Use only new parts when making SRS repairs. |
• |
Carefully inspect any SRS parts before installation. Do not
install any parts that show 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. |
• |
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 any electrical inspections, such as measuring resistance, to the airbags. |
• |
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 impact or bump on the SRS unit, the side
impact sensors or the front impact sensors whenever the ignition switch
is ON. Wait for at least three minutes after the ignition switch is
turned OFF before beginning to work. |
• |
During installation or replacement, be careful not to bump on
the area (by impacting with a wrench, hammer, etc.) around the SRS
unit, the side impact sensor and the front impact sensor as any impact
on the airbags may accidentally deploy them to cause possible damage or
injury. |
• |
Replace the front airbag module, SRSCM and FIS after the
front airbag is deployed. Replace the airbag wiring if it is damaged.
Replace the side airbag module, the curtain airbag module, SRSCM and SIS
after the side airbag is deployed. Replace the airbag wiring if it is
damaged. |
• |
If the airbags or the side airbags were not deployed in a
collision, inspect for any damage or deformation on the SRS unit and the
side impact sensors. If any damage is found, 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 for at least three minutes before beginning to install
or replace the SRS unit. |
• |
Be sure that the SRS unit, the front impact sensor and side impact sensors are installed securely with mounting bolts. |
• |
Be careful not to spill water or oil on the SRS unit, 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. |
• |
Never attempt to modify, splice or repair SRS wiring. If there is an opening or damage on SRS wiring, replace the harness. |
• |
Be sure to install the harness wires so that they are not pinched, or interfering 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. |
• |
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 force the probe into a connector. |
• |
Use specified service connectors for troubleshooting.
Using improper tools could cause an error in inspection due to poor metal contact. |
