1998 HONDA CIVIC combination light switch

Precautions/ Procedures
)General Precautions
r 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 defor-
mation:
- Airbags- Cable reel
- SRS unit
-
Use only a digital multimeter to check the system lf
it's not a Honda multimeter, make sure its output ls
1O mA (0.01 A) or less when switched to the smallest
value in the ohmmeter range. A tester with a higher
output could damage the airbag circuit or cause acci-
dental deployment and possible injury'
I Do not install used SRS parts from another vehicle
When making SRS repairs, use only new pans'
) Except when performing electrical inspections'
always disconnect both the negative cable and posl-
tive cable from the battery, and wait at least three
minutes before beginning work
r Replacement of the combination light and wiper/
washer switches and cruise control switch can be
done without removing the steering wheel:
- Combinalion light and wiper/washer switch replace
ment, see section 23
- Cruise control sevresume switch replacement' see
section 23.
. Whenever the ignition switch is ON {ll), or has been
turned OFF for less than three minutes' be careful not
to bump the SRS unit; the airbag(s) could accidental-
ly deploy and cause damage or injury'
. Whenever the airbag{s) has(have) been activated'
replace the SRS unit.l,

Airbag Handling and Storage
Do not try to disassemble the airbag assembly. lt has no
serviceable parts Once an airbag has been operated
(deployed). it cannot be repaired or reused'
For temporary storage of the airbag assembly during ser-
vice. olease observe the following precauttons:
. store the .emoved airbag assemblv with the pad sur-
face uo The driver's (and front passenger's) airbag
connecto''s'-as {have) a built.in short contact (see

force lo c.usa 3a.ix! intury
AIRBAG CONNECTORS(With built in shon contact)
. Store the removed airbag assembly on a secure flat
surface away from any high heat source {exceeding
212"FI1OO"CJ and free of any oil' grease, detergent or
water.
CAUTION: lmproper handling or storage can intern'lJy
damage the airbag assembly, making it inoperativo
lf you suspect the airbag assembly has been dam€cd'
inslall a new unit. and relsr lo the Deployment/DisPG'l
