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.

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

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).

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.
