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.

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.

Supplemental Restraint System (SRSI
Troubleshooting
Self-diagnosis Function
The SRS unit includes a self-diagnosis function. lf there
is a failure in the sensors. SRS unit, inflator, or their cir-
cuits, the SRS indicator light in the gauge sssembly
comes ON.
As a system check, the SRS indicator light also comes
on when the ignition is first turned ON to the (ll) posi-
tion. lf the light goes off after approximately six sec-
onds, the system is OK.
lf the SRS indicator lighr remains on (or fails to come on
in the system check mode), one of the SRS components
(or the wiring/connectors inbetween) is laulty
Troubleshooting Precautions
a Always use the test harness. Do not use test probes
directly on component connector terminals or wires;
you may damage them or the SRS unit.
a When connecting any of the test harnesses to the
system, push the connectors straight-in; do not bend
the connector terminals,
. Before disconnecting any part of the SRS wire har-
ness, connect the shon connector (RED) on the driv-
er's airbag. On cars equipped with a front passen-
ger's airbag, connect short connectors on the driver's
airbag and the front passenger's airbag.
SRS Indicator Light Troubleshooting
Possiblo conditions:
1. SRS indicator light does not come on at all - see
page 23-278.
2. SRS indicator light stays on constantly - see page
23-242.
3. SRS indicator light comes on in combination with a
failure of another electrical system (charging sys-
tem light). Check for damage/corrosion at the
under-dash tuse/relay box connector.
NOTE:
. Before starting the applicable troubleshooting. check
the condition of all SRS connectors and ground
points.
. lf the fault is not found after completing the applica-
ble troubleshooting, substitute a known-good SRS
unit and check whether the indicator light goes off.
