Troubleshooting
Self-diagnosis Function
The SRS unit includes a self-diagnosis function. If there
is a failure in the sensors, SRS unit, inflator, or their cir-
cuits, the SRS indicator light in the gauge assembly
goes ON.
SRS INDICATOR LIGHT
As a system check, the SRS indicator light also comes
on when the ignition is first turned to the II position. If
the light goes off after approximately six seconds, the
system is OK.
If the SRS indicator light remains on (or fails to come on
the system check mode) one of the SRS components
(or the wiring/connectors in-between) is faulty.
Troubleshooting Precautions
Always use the test harness. Do not use test
probes directly on component connector ter-
minals or wires; you may damage them or the
control unit.
When connecting any of the test harnesses to
the system, push the connectors straight-in; do
not bend the connector terminals.
Before disconnecting the airbag connector(s),
turn off the ignition switch and wait for at least
three minutes to let the capacitor in the back-up
circuit discharge. This will prevent a malfunction
of the seat belt tensioners.
Before disconnecting any part of the SRS wire
harness, install the short connector (RED) on the
airbags and both seat belt tensioners. After in-
stalling the short connectors on the airbags,
immediately install one SRS Service Connector
(Tool Number 07MAZ-SP0020A) on the cable
reel connector (for the driver's airbag), and
another on the SRS main harness connector (for
the passenger's airbag). This will prevent any
static electricity from triggering the seat belt
tensioners before you disconnect them (see page
24-10).

SRS Indicator Light Troubleshooting
Possible conditions:
1. SRS indicator light does not come on at all — see
page 24-15.
2. SRS indicator light stays on constantly — see page
24-18.
3. SRS indicator light comes on in combination with a
failure of another electrical system (brake system
light, malfunction indicator lamp etc.). Check for
damage/corrosion at the under-dash fuse box.
NOTE:
Before starting the applicable troubleshooting,
check the condition of all SRS connectors and
ground points.
If the fault is not found after completing the ap-
plicable troubleshooting, substitute a known-
good SRS unit and check whether the SRS in-
dicator light goes off. If it does, the original SRS
unit must be faulty; replace it.
