Honda 1994 Accord Coupe Owner's Manual page 212

The SRS includes the steering wheel
airbag assembly, sensors in the
dashboard, and a control unit with
sensors behind the center console.
The system also has a dashboard-
mounted airbag assembly for the
passenger.
The sensors are decelerometers, set
to trigger in a severe frontal impact
that generates more force than a 25
mile per hour crash into a parked
vehicle of similar size. For the SRS to
activate, at least two sensors must
trigger. This duplication is to prevent
accidental activation.
When the control unit receives
trigger signals from at least two
sensors, it sends voltage to the
airbag. The control unit stores this
charge in capacitors to insure
reliability even if a severe impact
damages the car's battery or
electrical connections.
The electrical charge sent to the
airbag assembly ignites its propellant,
which burns instantaneously. The
gas produced by the burning
propellant inflates the airbag
instantly.
The airbag is vented so it stays
inflated for only an instant and does
not block the driver's vision. Smoke
from the burned propellant comes
out of the airbag and into the car's
interior. This is normal and does not
mean there is a fire. The airbag
collapses onto the driver's lap.
Supplemental Restraint System
The airbag unit can inflate only one
time. After use, your Honda dealer
must check the complete Supple-
mental Restraint System and replace
the airbag assembly.
To ensure long-term reliability, the
SRS uses gold-plated electrical
connections throughout. Exposed
components are sealed with epoxy.
The control unit monitors the SRS
circuitry whenever the ignition is ON
(II). If the control unit senses any
faults, it turns on the SRS indicator
light on the instrument panel. Take
the car to your Honda dealer to
diagnose and repair the system as
soon as possible.
The SRS needs no regular mainte-
nance other than an inspection by
your Honda dealer ten years after
manufacture.
