1997 GMC JIMMY sensor

What will you see after an air bag inflates?
After an air bag inflates, it quickly deflates,
so quickly
that some people may not even realize the air bag
inflated. Some components of the
air bag module in the
steering wheel hub
will be hot for a short time. The parts
of the bag that come into contact with you may be
warm, but not
too hot to touch. There will be some
smoke and dust coming from vents
in the deflated air
bag. Air bag inflation doesn’t prevent the driver from
seeing or from being
able to steer the vehicle, nor does it
stop people from leaving the vehicle.
When an
air bag inflates, there is dust in the air.
This dust could cause breathing problems for
people with
a history of asthma or other
breathing trouble.
To avoid this, everyone in the
vehicle should get out
as soon as it is safe to do so.
If you have breathing problems but can’t get out
of the vehicle after an air bag inflates, then get
fresh air by opening a window
or door.

The air bag is designed to inflate only once. After it
inflates? you‘ll need some new parts for your air bag
system.
If you don’t get them, the air bag system
won’t be there to help protect you
in another crash.
A new system will include the air bag module and
possibly other parts. The service manual for
your
vehicle covers the need to replace other parts.
Your vehicle is equipped
with a diagnostic module,
which records information about the air bag system.
The module records information about the readiness
of the system, when the sensors are activated and
driver’s safety belt usage at deployment.
Let only qualified technicians work on your air bag system. Improper service can mean that your air bag
system won’t work properly. See your dealer
for service.
NOTICE:
If you damage the cover for the driver’s air bag,
the bag may not work properly. You may have to
replace the air bag module.
Do not open or break
the air bag cover.

Servicing Your Air Bag-Equipped Vehicle
The air bag affects how your vehicle should be serviced.
There are parts of the air bag system
in several places
around your vehicle. You don't want
the system to
inflate while someone is working on your vehicle. Your
GM dealer and the GM Service Manual have
information about servicing your vehicle and
the air bag
system.
To purchase a service manual, see "Service and
Owner Publications''
in the Inde-x.
~~ -
A CAUTION:
For up to two minutes after the ignition key is
turned off and the battery is disconnected, an air
bag can still inflate during improper service.
You
can be injured if you are close to an air bag when
it inflates. Avoid wires wrapped with yellow tape,
or yellow connectors. They are probably part of
the air bag system. Be sure to follow proper
service procedures, and make sure the person
performing work for you
is qualified to do so.
The air bag system does not need regular maintenance.
Adding Equipment to Your Air
Bag-Equipped Vehicle
Q: If I add a push bumper or a bicycle rack to the
front
of my vehicle, will it keep the air bag from
working properly?
A: As long as the push bumper or bicycle rack is
attached to your vehicle
so that the vehicle's basic
structure isn't changed, it's
not likely to keep the
air bag from working properly
in a crash.
Is there anything I might add to the front of the
vehicle that could keep the air bag from
working properly?
A: Yes. If you add things that change your vehicle's
frame. bumper system, front end sheet metal or
height, they may keep the air bag system from
working properly.
Also, the air bag system may not
work properly if you relocate any of the air bag
sensors.
If you have any question about this, you
should contact Customer Assistance before you
modify your vehicle.
(The phone numbers and
addresses for Customer Assistance are
in Step Two of
the Customer Satisfiction Procedure
in this manual.
See "Customer Satisfaction Procedure"
in the Index.)
