General Precautions
Carefully inspect any SRS part before you install it.Do not install any part that shows signs of beingdropped or improperly handled, such as dents, cracksor deformation:
- Airbag assembly {driver's and front passenger's)
Airbag Handling and Storage
Do not try to disassemble the airbag assembly. lt has noserviceable parts. Once an airbag has been operated(deployed), it cannot be repaired or reuseo.
For temporary storage of the airbag assembly duringservice, please observe the following precautions:
. Store the removed airbag assembly with the pad sur-face up.
!@ It the airbag is impropsrty stored facsdown, accidental deployment could propel the unit withenough force to cause setious iniury
Store the removed airbag assembly on a secure flatsufface away from any high heat source (exceeding
212"Fl1OO'Cl and free of any oil. grease, detergent or
CAUTION: lmproper handling or storage can internallydamage the airbag assembly, making it inoperativ€.ll you suspect the airbag assembly has been damagod,install a new unit and rgler to the Deployment/DigposalProcedures lor disposing of the dsmaged airbag.
Use only a digital multimeter to check the system. lfit's not a Honda multimeter make sure its output is 10mA (0.01 A) or less when switched to the smallestvalue in the ohmmeter range. A tester with a higheroutput could damage the airbag circuit or cause accidental deployment and possible injury.
Do not install used SRS parts from another car. Whenmaking SRS repai.s, use only new pans.
Except when performing electrical inspections,always disconnect both the negative cable and posi-
tive cable at the battery before beginning work.
Replacement of the combination light andwiper/washer switches and cruise control switch canbe done without removing the steering wheell

The original radio has a coded theft protection circuit.Be sure to get the customer's code number beforedisconnecting the battery.
When reinstalling the SRS unit cover, be sure it snapstogether properly.

Wiring Precautions
o Never attempt to modify. splice or repair SRS wiring.
NOTE: All SRS electrical wiring harnesses are covered
with yellow insulation.
Be sure to install the harness wires so that they are
not pinched or interfering with other car pans.
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.

Connecting the Short Connectors
@ To avoid accident8l deploymont and pos-
5ibl6 iniury, slways insiall the protectiva short connec-
tor(s) on tho drivgr'3 and passengor's airbag connec.
tor(s) be{ore working noar any SRS wiring.
NOTE: The original radio has I coded theft protection
circuit. Be sure to get the customer's code number
before disconnecting the battery cables.
1. Disconnect the battery negative cable. then discon-
nect the Dositive cable.
2. Connect the short connector(s) {RED):
Driver's Side:
. Remove the access panel from the steering wheel.
then remove the short connector (RED) from the
Daner.
DRIVER'SAIRBAG
CONNECTORIREDI
Disconnect the 3-P connector between the driver's
airbag and cable reel, then connect the short connec-
tor {RED} to the airbag side oi the connector.

Front Pas3enger's Side:
. Remove the glove box damper (see section 20), and
then remove the glove box.
. Disconnect the 3-P connector between the front oas-
senger's airbag and the SRS main harness, then con-
nect the short connector (RED) to the airbag side of
the connector.

Disconnecting the SRS Connector at the
Under-dash Fuse/relay Box:
CAUTION: Avoid br.aking the connoctor; it's doubte-
locksd.
1. First lift the connector lid with a thin screwdriver,
then press the connector tab down and pull the con-neclor out.

Steerin g-related Precautions
Steering Wheel and Cable Reel Alignment
NOTE: To avoid misalignment of the steering wheel or
airbag on reassembly, make sure the wheels are turned
straight ahead before removing the steering wheel.
Rotate the cable reel clockwise unit it stops.
Then rotate it co u nterclockwise (approximately two
turnsl until:
- The yellow gear tooth lines up with the alignment
mark on the cover.- The arrow mark on the cable reel label points straight
up.

Steering Column Removal
CAUTION:
. Bofore romoving tho 3l6oring column, first discon'
nect tha connector between ths cablo 16ol snd tho
SRS main harness.
. lf th6 stssring column is going to be removed with-
out dbmounting the stesring wh6el, lock the sl6sr-
ing by turning th€ ignition k.y to o-LOCK po3ition or
removo tha k€y llom ths ignilion so that th6 3loaring
wheel will not turn.
Do not replace the original steering wheei with any
other design, since it will make it impossible to properly
instsll the airbag (only use genuine Honda replacement
oans).
After reassemblv confirm that the wheels are still turned
straight ahead and that the steering wheel spoke angle
is correct, lf minor spoke angle adjustment is necessary,
do so only by adjustment of the tie-rods, not by remov-
ing and repositioning the steering wheel.

Sensor Inspection
CAUTION: Tak€ €xtra care whon painting or doing
body work in the ar€a bslow th6 dalhboard.
Avoid dirost exposure ot lh6 sonsors or wiring to hestguns, wolding, or spraying equipmont.
Di3connact both the nogativo and po3itivo b!ftery
cable3.
Connsct tho short conneclor(s) before working
bslow the da3hboard or nsar lhe dash sen3o.3.
After any degree of frontal body damage, inspect
both dash sensors. Replace a sensor if it is dented,
cracked, or deformed.
DASH SENSOR
a Be sure the sensors are installed securelv,
Inspection After Deployment
After a collision in which the airbags were deployed.
inspect the following:
1. Inspect the dash sensors for physical damage.
lf the sensors are damaged, replace them.
2. Inspect all the SRS wire harnesses, ReDlace, don'trepair, any damaged harnesses.
3. Inspect the cable reel for heat damage. lf there is
any damage. replace the cable reel.
4. After the car is completely repaired. turn the igni-tion switch on. lf the SRS indicator light comes onfor about six seconds and then goes off, the SRS
system is OK. lf the indicator light does not functionproperly, go to SRS Troubleshooting (next page).
