Precautions/Procedures
General Precautions
Carefully inspect any SRS part before you install it,
Do not install any part that shows signs of being drop-
ped or improperly handled. such as dents, cracks or
deformstion:
- 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 is
10 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.
r Do not install used SRS parts from anothercar.When
making SRS repairs, use only new parts.
r 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:
- Combination light and wiperlwasher switch replace-
ment (see page 23-268).- Cruise controi sevresume switch replacement (see
page 23-259t .
. Whenever the ignition switch is ON (ll), or has been
turned OFF for less than three minutes, be caretul not
to bump the SRS unit; the airbags could accidentally
deploy and cause damage or iniuries.
. Whenever the airbag has been activated, replace the
SRS unit.
. The original radio has a coded theft protection circuit.
Be sure to get the customer's code number beJore dis-
connecting the battery cables.

Airbag Handling and Storage
Do not try to disassemble the airbag. lt has no service-
able parts. Once an airbag has been operated
(deployed), it cannot be repaired or reused.
For temporary storage of the airbag during service,
please observe the following precautions:
. Store the removed airbag with the pad surface up.
The driver's and tront passenger's airbag connectors
have 8 built-in short contact (see page 23-284).
@ r the airbag is improp€rly storcd face down,
accidental deployment could propel the unit with enough
force to caus6 serious iniury.
AIRBAG CONNECTORS(Built-in short contact)
. Store the removed airbag on a secure flat surface
away from any high heat source (exceeding
212F110O'CI and free of any oil, grease, detergent or
water.
CAUTION: lmproper handling or storage can intornally
damags the airbag, making it inoperative.
1l you su3pocl the aitbag has been damaged, install a ncw
unit and rofEr to ths Deployment/Dilpolal Procedures for
dbposing of ihe damsged ailbag.

Precautions/Procedu res
SRS Unit Precautions
Take extra caro when painting or doing body work in
the area below the dashboard. Avoid direct exposure
of the SRS unit or wiring to heat guns, welding, or
spraying equipment.
Disconnect the airbsg connector(s) before discon-
necting SRS harness connectors (see page 23-2851.
After any degree of frontal body damage, or after a
collision without airbag deployment, inspect the SRS
unit for physical damage. lf it is dented, cracked, or
deformed, reDlace it.
Be sure the SRS unit is installed securelv.
Do not disassemble the SRS unit.
Store the SRS unit in a cool (lass than about
104'F/40"C) and dry (less than 80% humidity, no mois-
ture) place, Do not spill water or oil on the SRS unit,
and keeD it awav trom dust.
During installation or r6placement, be careful not to
bump {impact wrench, hammer, etc.) the area around
the SRS unit. The airbags could accidentally deploy
and cause damsge or injuries,
v
Inspection After Deployment
After a collision in which the airbags w6re deployed,
replace the SRS unit, and inspect the following:
1, Inspect all the SRS wire harnesses. Replace, don't
repair, any damaged harnesses
2. Inspect the cable reel for heat damage. lf there is any
damage. replace the cable reel.
3. After the vehicle is completely repairod, turn the
ignition switch ON {ll). lf the SRS indicator light
comes on for about six seconds and then goes off,
the SRS system is OK. lf the indicator light does not
function properly. go to SRS Troubleshooting.
23-282
Disconnecting the Airbag Connector(s)
!@ To prevent accidental airbag dsploymcnt, turn ths ignition switch OFF, disconnect the negrtive battory
able, and wait three minut€s before disconnesting any SRS Glnnoqto.s.
. Before disconnecting the SRS main harness {A)from the SRS unit, disconnect both airbags (C, D).
. Before disconnecting the cable reel 2P con nector ( B). disconnect the driver's airbag 2P connector (C).
)
1. Disconnect the negative baftery cable. and wait at
least three minutes.
2. Disconnect the airbag connector(s).
Driver's Side:
. Remove the access panel from the steering wheel,
then disconnect the driver's airbag 2P connector and
cable reel 2P connector.

Troubleshooting
Self-diagnostic Procedures
The self-diagnostic function of the SRS system allows it to locate the causes of system problems and to store this informa-
tion in memorv. For easier troubleshooting, this data can be retrieved via 8 dats link circuit.
o When you turn the ignition switch ON (ll), the SRS indicator will come on. lf it goes off after six seconds, the system is
normat.
. lf there is 8n abnormality, the system locstes and defines the problem, stores this information in memory, and turns
th€ SRS indicator light on. The data will remain In the memory even when the ignition switch is turned off or if the bat-
terv is disconnected.
. When you connect the SCS service connector to the service check connector (2P), and turn the ignition switch ON {ll),
the sRs indicator light will indicate the diagnostic trouble code (DTCI by th€ number of blinks.
. After reading and recording the DTC, proceed with the troubleshooting for this code
Pr6crution!
. Use only a digital multimeter to check the system, lf it's not a Honda multimeter, make sure its output is 10 mA (0.01 A)
or less when switched to the smallest value in the ohmmeter range. A tester with a higher output could damsge the
airbag circuit or cause sccidental airbag deployment and possible injury.

. Make sure the battery is sufficiently charged (s6e psge 23-67). lf the battsry is dead or low, msasuring values won't be
correct,
a Do not touch a tester probe to the terminals in the SRS unit or harness connectors, and do not connect the terminals
with a jumper wire. Use only the backprobe set and the SCS service connector.
For backprobing spring-loaded lock type connectors, refer to psge 23-283.
