Chrysler PT Cruiser. Manual — part 516
pressed to the first detent, input is received by the
driver window regulator module and passenger win-
dow regulator module, which will lower the front
windows approximately 40 mm, and lower the rear
windows approximately 55 mm. After a 200 ms delay,
it energizes the power top down relay to lower the
convertible top.

DESCRIPTION
FRONT AIRBAG SYSTEM
A dual front airbag system (Fig. 1) utilizes driver
and passenger airbags. Both the driver and passen-
ger airbags are certified to new federal regulations,
which allows them to deploy with less force than
prior airbags. The primary occupant restraints in
this vehicle are the seat belts, which require active
use by the vehicle occupants. The front airbag system
is
a
supplemental
passive
restraint
that
was
designed and is intended to enhance the protection
for the front seat occupants of the vehicle when used
in conjunction with the seat belts.
The driver airbag includes an inflatable airbag and
an inflator unit behind a trim cover in the hub area
of the steering wheel. The passenger airbag includes
an inflatable airbag and an inflator unit behind an
airbag door in the instrument panel above the glove
box.
The dual front airbag system consists of the follow-
ing components:
• Occupant Restraint Controller (ORC)
• Airbag indicator lamp.
• Clock Spring
• Driver and passenger airbags (including the air-
bag inflators).
• Wire harness and connections.
Refer to the proper Body Diagnostic Procedures
manual to test or diagnose a problem with any com-
ponent of the front airbag system.
SIDE IMPACT AIRBAG SYSTEM
The Side Impact Airbag System utilizes two air-
bags, one mounted to each front seat back frame.
This system is designed to enhance protection of
occupants in the event of a side impact collision. The
ORC supports the Satellite Acceleration Sensors
(SAS), Seat Airbags, and an accelerometer that pro-
vides verification of the direction and severity of an
impact from the both sides.
BELT TENSIONER SYSTEM
The seat belt system incorporates Tensioner Mod-
ules. They are integral to the seat belt retractors
(Fig. 2) and cannot be serviced. If found defective
they must be replaced.
OPERATION
FRONT AIRBAG SYSTEM
The front airbag system electrical circuits are con-
tinuously monitored by a microprocessor and soft-
ware
contained
within
the
Occupant
Restraint
Controller (ORC). The ORC also contains impact
sensing elements, which are monitored by the ORC
to determine when an impact occurs that is severe
enough to require front airbag system protection.
When a frontal impact is severe enough, the ORC
initiates the inflator units of both front airbags to
deploy.
An airbag indicator lamp in the instrument cluster
lights for six to eight seconds as a bulb test each
time the ignition switch is turned to the ON position.
Following the bulb test, the airbag indicator lamp is
turned ON or OFF by the ORC to indicate the status

of the airbag system. If the airbag indicator lamp
comes ON at any time other than during the bulb
test, it indicates that there is a problem in the airbag
system. Such a problem may cause the airbags not to
deploy
when
required,
or
to
deploy
when
not
required.
During a frontal vehicle impact, the knee blockers
work in conjunction with properly adjusted seat belts
to restrain the driver and front seat passenger in the
proper position for an airbag deployment. The knee
blockers also work to absorb and distribute the crash
energy from the driver and front seat passenger to
the structure of the instrument panel. The driver
side knee blocker is integral to the lower instrument
panel bezel. The passenger side knee blocker is inte-
gral to the glove box door.
SIDE IMPACT AIRBAG SYSTEM
The ORC controls the seat back mounted airbags
(one left and one right). If a ORC determines the
impact is severe enough, based upon a signal from
the Satellite Acceleration Sensor (SAS), the ORC will
send a signal over the Programmable Communication
Interface (PCI date bus and the appropriate airbag
will inflate, tearing open the front seat back trim
cover protecting the occupants. Once a seat back
mounted airbag has been deployed, the entire seat
back as well as any damaged parts must be replaced.
BELT TENSIONER SYSTEM
At the onset of an impact event, each tensioner
uses a pyrotechnic device which is triggered simulta-
neously with the airbags to rapidly retract the seat
belts. With the slack removed, the occupant’s forward
motion in an impact will be reduced as will the like-
lihood of contacting interior components.
WARNING:
WHEN
THE
FRONT
AIRBAG
IS
DEPLOYED,
THE
TENSIONER
WILL
HAVE
DEPLOYED ALSO, AND MUST BE REPLACED.
The ORC monitors the seat belt tensioner circuit
and reports active and stored Diagnostic Trouble
Codes (DTC’s) if any problem is found.
Once a vehicle has been in an accident, the ten-
sioner will have a “Gravel/Grinding“ sound to it after
the tensioner has been put into use. This must be
replaced along with any deployed airbags and broken
or damaged parts.
WARNING
FRONT AIRBAG SYSTEM
This system contains a sensitive, complex
electronic unit. Disconnect and isolate the bat-
tery negative remote cable before beginning
airbag system component removal or installa-
tion procedures. This will disable the airbag
system. Failure to disconnect the battery could
result in accidental airbag deployment, per-
sonal injury, or death.
Allow system capacitor to discharge for two
minutes before removing airbag components.
Do not place an intact undeployed airbag
face down on a solid surface, the airbag will
propel into the air if accidentally deployed and
could result in personal injury or death. When
carrying or handling an undeployed airbag, the
trim side of the airbag should be pointing
toward the body to minimize possibility of
injury
or
death
if
accidental
deployment
occurs.
Replace
airbag
system
components
with
Mopar
t replacement parts only. Substitute
parts may appear interchangeable, but internal
differences may result in inferior occupant pro-
tection, personal injury or death.
Wear safety glasses, rubber gloves, and long
sleeved clothing when cleaning powder residue
from the vehicle after an airbag deployment. A
powder residue emitted from a deployed airbag
can cause skin irritation. Flush affected area
with cool water if irritation is experienced. If
nasal or throat irritation is experienced, exit
the vehicle for fresh air until the irritation
ceases. If irritation continues, see a physician.
Do not use a replacement airbag that is not in
the original packaging, improper deployment,
personal injury or death may result.
The factory installed fasteners, screws and
bolts used to fasten airbag components have a
special coating and are specifically designed
for the airbag system. Do not use substitute fas-
teners, use only original equipment fasteners
listed
in
the
parts
catalog
when
fastener
replacement is required.
Airbags should be stored in a cool, dry place,
away from excessive heat and static electrical
activity with the fabric airbag facing up. If not,
a premature deployment can result in personal
injury or death.
Please refer to the Hazardous Substance Con-
trol System for Proper Disposal. Dispose of
deployed air bags in a manner consistent with
state, provincial, local, and federal regulations.
SIDE IMPACT AIRBAG SYSTEM
The side impact airbag system contains sensi-
tive, complex electronic units. Before attempt-
ing to diagnose or service any side impact
airbag system components, you must first dis-
connect
and
isolate
the

(ground) cable. This is the only sure way to dis-
