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.
