'\' '\, ili \.-.-1 i^\\,,; i \
The SRS is a safetv device which, when used in coniunction with the seat belt, is designed to help protect the driver and
front passenger in a frontal impact exceeding a cenain set limit. The system consists ot the SRS unit (including safing sen-
sor and imDact sensor), the cable reel, the driver's airbag, and front passenger's airbag
Operation t'Its
The main circuit in the SRS unit senses and judges the force ot impact and, il necessary, ignites the inflator charges. If bat-
tery voltage is too low or power is disconnected due to the impact, the back-up power circuii will keep voltage at a con-
stant level.
For the SRS to operate:
(1) The impact sensor and safing sensor must activate and send electric signals to lhe mictop.Goi
{2) The microprocessor must compute the signals and send signals to the airbag inflators'
(3) The inflators must ignite and deploy the airbags sE Lr.r

Self-diagnosis System
A self-diagnosis circuit is built into the sRs unit; when the ignition switch is turned oN (ll), the sRS indicator light comes
on and goes off after about six seconds if the system is operating normally'
lf the light does not come on, or does not go off after six seconds, or if it comes on while driving. it indicates an abnormal-
ity in the system. The system must be inspected and repaired as soon as possible'
For better servicesbility. the memory will store the cause of the malfunction, and the data link circuit passes on the infor-
mation from the memory to the data link connector (DLC). This information can be read with the Honda PGM Tester con-
nected to the DLc (16P).

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.
23-281
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.

Precautions/Procedures
Spring-loaded Lock ConneetorSpring-loaded Lock Gonnector
with Built-in Short Contact
The driver's and front passenger's airbag have a spring-
loaded lock connector with a built-in short contact.
When this connector is disconnected, the power termi-
nal and the ground terminal in the airbag connector are
automatically shorted.
