1996 GMC SAVANA sensor

0 0 . Your vehicle is equipped with a crash sensing and
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 or the
right front passenger’s
air bag, they may not
work properly.. You may have to replace the
air bag module in the steering wheel or both the
air bag module and the instrument panel for the
right front passenger’s
air bag. Do not open or
break the
air bag covers.
Servicing Yodr Air Bag-Equipped Vehicle
Air bags affect 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 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 Index.
For up to 10 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
@ Lf I add a push bumper or a bicycle rack to the
front of my vehicle, will it keep the air bags
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 bags from working properly
in a crash.
Q: Is there anything I might add to the front of the
vehicle that could keep the air
bags 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 Satisfaction Procedure
in this manual.
See “Customer Satisfaction Procedure”
in the Index.)

for a few seconds when you
turn your ignition
to RUN
or START. Then the light
should
go out. This means
If the air bag readiness light doesn’t come on when you

Voltmeter
When your engine is not
running, but the ignition
is
on (in the RUN position),
this gage shows your
9
h
19 battery’s state of charge
in DC volts.
u
VOLTS
When the engine is running, the gage shows the
condition of
the charging system. Readings between
the low and high warning zones indicate the normal
operating range.
Readings
in the low warning zone may occur when a
large number of electrical accessories are operating in
the vehicle and the engine is left at an idle for an
extended period. This conditi.on is normal since the charging
system
is not able to provide full power at
engine idle.
As engine speeds are increased, this
condition should correct itself as higher engine speeds
allow
the charging system to create maximum power.
You can only drive for
a short time with the reading in
either warning zone. If you must drive, turn
off all
unnecessary accessories.
Readings
in either warning zone indicate a possible
problem in the electrical system. Have the vehicle
serviced
as soon as possible.
Electronic Road-Speed Governor (Gasoline Engines)
This optional system automatically controls vehicle top
speed. The system controller receives
a signal from the
vehicle speed sensor and reduces power when the
vehicle speed reaches
the maximum 65 mph (105 km/h)
governed speed.
