Supplemental Restraint System
The Honda Supplemental
Restraint System (SRS) is
standard on all Accord Wagons
sold in the U.S. and Canada.
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
front seat 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, both
sensors must trigger. This
duplication is to prevent
accidental activation.
When the control unit receives
trigger signals from both sensors,
it sends voltage to the airbags.
The control unit stores this
charge in capacitors to ensure
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 airbags are vented so they
stay inflated for only an instant
and do 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 airbags
collapse onto the driver's and
passenger's laps.
The airbags and SRS control unit
must be replaced after the system
is activated. After use, your
Honda dealer must check the
complete Supplemental Restraint
System and replace the airbag
assemblies.
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
maintenance other than an
inspection by your Honda dealer
10 years after manufacture.
