Combination Light Switch Test
1.Remove the driver's dashboard lower cover and steering column covers (see section 20)
Disconnect the 4P and 7P connectors from the switch.
Inspect the connector and socket terminals to be sure they are all making good contact
. lf the terminals are bent, loose. or corroded, repair them as necessary, and recheck the system.
. lf theterminals look OK, check for continuity between them ineach switch position according tothetables lfthere
is no continuity between any of them. check for continuity in the switch harness
- lf there is continuity in the switch harness. replace the combination light switch
- lf there is no continuity in the switch harness, replace it.

Inspect the connector and socket terminals to be
sure they are all making good contact.
lf the terminals are bent, loose or corroded. repair

lf the terminals look OK, make the following
input tests at the connector,- lf any test indicates a problem, find and correct
the cause, then recheck the system.- lf all the input tests prove OK, the control unit

'1. Carefully pry the controller out of the dashboard.
2. Disconnect the 3P connector from the controller'
3. Inspect the connector terminals to be sure they are
all making good contact.
. lf the terminals are bent, loose, or corroded, repair
them as necessary, and recheck the system.
. lf the terminals look OK, make the following input
tests at the connector.- lf any test indicates a problem, find and cor-
rect the cause, then recheck the system.

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
page 2a-l 1
: | ..r r-+r-a k imninncrlv slorcd lace down,-""dd.r6t dtatltt-,tl could propel the unit whh enough
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
olocedules for disposing ol the damaged airbag
