SEAT BELT TENSIONER
DESCRIPTION
The seat belt system incorporates Seat Belt Ten-
sioners. The tensioner is designed to hold the occu-
pant in their respective seat by retracting the seat
belt up to four inches. They are integral to the front
seat belt buckles and cannot be serviced. If found
defective they must be replaced. After an airbag
deployment, the tensioner must be replaced.
Seat Belt Tensioners supplement the dual front air-
bag system. The seat belt tensioners are integral to
the front seat belt buckles, which are secured to the
seat cushion frame on the inboard side. The seat belt
tensioners are controlled by the Occupant Restraint
Controller (ORC) and are connected to the vehicle
electrical system through the body wire harness.
The seat belt tensioners cannot be repaired and, if
faulty or damaged, the entire front seat belt buckle
must be replaced. The seat belt tensioners are not
intended for reuse and must be replaced following
any front airbag deployment.
OPERATION
WARNING: When the front airbag is deployed, the
tensioner will have deployed also and should be
replaced. Failure to do so could result in occupant
personal injury or death.
The seat belt tensioners are deployed by a signal
generated by the Occupant Restraint Controller
(ORC) through the driver or passenger seat belt ten-
sioner line 1 and line 2 (or squib) circuits. When the
ORC sends the proper electrical signal to the tension-
ers, the electrical energy generates enough heat to
initiate a small pyrotechnic gas generator.
Removing excess slack from the front seat belts not
only keeps the occupants properly positioned for an
airbag deployment following a frontal impact of the
vehicle, but also helps to reduce injuries that the
occupants of the front seat might experience in these
situations as a result of a harmful contact with the
steering wheel, steering column, instrument panel
and/or windshield.
The ORC monitors the condition of the seat belt
tensioners through circuit resistance, and will illumi-
nate the airbag indicator in the ElectroMechanical
Instrument Cluster (EMIC) and store a Diagnostic
Trouble Code (DTC) for any fault that is detected.
For proper diagnosis of the seat belt tensioners, use a
scan tool and the appropriate diagnostic information.
SEAT WEIGHT BLADDER &
PRESSURE SENSOR
DESCRIPTION
Vehicles equipped with the Occupant Classification
System (OCS) have a seat weight bladder and pres-
sure sensor unit (Fig. 54) that is integral to the pas-
senger front seat cushion. The bladder is sandwiched
between the seat cushion pan and seat cushion foam.
The bladder consists of two rectangular sheets of
an elastomeric material and a molded plastic elbow
fitting. The two sheets of material are sealed
together around their perimeter and heat staked to
each other at numerous regular points within their
field. The elbow fitting is sealed to a small round
hole in the lower surface of the bladder and is
pointed downward where it passes through a clear-
ance hole in the insulator pad and extends to just
below the seat cushion. The bladder is then filled
with a silicone fluid to become a pliable, quilted
membrane.
Under the seat cushion a short tube is securely
clamped at one end to the bladder nipple, and at the
other end to a nipple on the electronic pressure sen-
sor. The sensor housing features an integral mount
that snaps over a tab integral to the stamped steel
Occupant Classification Module (OCM) mounting
bracket welded to the underside of the passenger
front seat cushion frame.

RSRESTRAINTS8O-43

The seat weight bladder and pressure sensor can-
not be adjusted or repaired. The components of the
passenger front seat cushion of a vehicle equipped
with the OCS including the cushion frame, seat
weight bladder and pressure sensor, seat cushion
foam, wire harness and the OCM are serviced only as
a factory-calibrated, assembled and tamper-evident
unit. Only the OCM and the seat cushion trim are
available for separate service replacement. Once a
service replacement package has been installed in a
vehicle, the OCM can thereafter be serviced only by
replacing the entire passenger front seat cushion unit
with another complete service replacement package.
OPERATION
The seat weight bladder and pressure sensor unit
is designed to sense the relative weight of a load
applied to the passenger front seat cushion, which
provides a logic input to the microprocessor of theOccupant Classification Module (OCM). When a load
is applied to the seat cushion, fluid within the blad-
der becomes pressurized. These changes in bladder
fluid pressure are measured by the pressure sensor
under the seat cushion through the bladder tube. As
the pressure within the bladder changes, the cir-
cuitry of the pressure sensor changes the output volt-
age of the sensor.
The pressure sensor receives a nominal five volts
and a ground through hard wired circuits from the
OCM. The OCM then monitors the pressure sensor
output voltage on the Programmable Communication
Interface (PCI) data bus circuit.
To properly diagnose the seat weight bladder and
pressure sensor, its communication with/between the
OCM, and all other components within the OCS, use
a scan tool and the appropriate diagnostic
information.

SEAT WEIGHT BLADDER & PRESSURE SENSOR (Continued)

(PCM) based upon the results. The ªVALID/INVALID
KEYº message communication is performed using a
rolling code algorithm via the Programmable Com-
munication Interface (PCI) data bus. A ªVALID KEYº
message must be sent to the Powertrain Control
Module (PCM) within two seconds of ignition ON to
free the engine from immobilization.
The SKREEM contains a Radio Frequency (RF)
transceiver and a microprocessor. The SKREEM
retains in memory the ID numbers of any Sentry Key
that is programmed to it. The maximum number of
keys that may be programmed to each module is
eight (8). The SKREEM also communicates over the
Programmable Communication Interface (PCI) data
bus with the Powertrain Control Module (PCM), the
Body Control Module (BCM), the Mechanical Instru-
ment Cluster (MIC), and the DRB IIItscan tool. The
SKREEM transmits and receives RF signals through
a tuned antenna enclosed within a molded plastic
ring formation that is integral to the SKREEM hous-
ing. When the SKREEM is properly installed on the
steering column, the antenna ring fits snugly around
the circumference of the ignition lock cylinder hous-
ing. If this ring is not mounted properly, communica-
tion problems may arise in the form of transponder-
related faults.
For added system security, each SKREEM is pro-
grammed with a unique9Secret Key9code. This code
is stored in memory and is sent over the PCI bus to
the PCM and to each key that is programmed to
work with the vehicle. The9Secret Key9code is there-
fore a common element found in all components of
the Sentry Key Immobilizer System (SKIS). In the
event that a SKREEM replacement is required, the
9Secret Key9code can be restored from the PCM by
following the SKIM replacement procedure found in
the DRB IIItscan tool. Proper completion of this
task will allow the existing ignition keys to be repro-
grammed. Therefore, new keys will NOT be needed.
In the event that the original9Secret Key9code can
not be recovered, new ignition keys will be required.
The DRB IIItscan tool will alert the technician if
key replacement is necessary. Another security code,
called a PIN, is used to gain secured access to the
SKREEM for service. The SKREEM also stores in its
memory the Vehicle Identification Number (VIN),
which it learns through a bus message from the
assembly plant tester. The SKIS scrambles the infor-
mation that is communicated between its components
in order to reduce the possibility of unauthorized
SKREEM access and/or disabling.
REMOTE KEYLESS ENTRY (RKE)
The RKE transmitter uses radio frequency signals
to communicate with the SKREEM. The SKREEM is
on the PCI bus. When the operator presses a buttonon the transmitter, it sends a specific request to the
SKREEM. In turn the SKREEM sends the appropri-
ate request over the PCI Bus to the:
²Body Control Module (BCM) to control the door
lock and unlock functions, the liftgate lock and
unlock functions, the arming and disarming of the
Vehicle Theft Security System (VTSS) (if equipped),
and the activation of illuminated entry.
²Integrated Power Module (IPM) to activate the
park lamps, the headlamps, and the horn for horn
chirp. If requested, the BCM sends a request over
the PCI Bus to the:
TIRE PRESSURE MONITORING (TPM)
If equipped with the Tire Pressure Monitoring
(TPM) System, each of the vehicles four wheels will
have a valve stem with a pressure sensor and radio
transmitter built in. Signals from the tire pressure
sensor/transmitter are received and interpreted by
the SKREEM.
A sensor/transmitter in a mounted wheel will
broadcast its detected pressure once per minute
when the vehicle is moving faster than 15 mph (24
km/h). Each sensor/transmitter's broadcast is
uniquely coded so that the SKREEM can determine
the location.
OPERATION
SENTRY KEY IMMOBILIZER
The Sentry Key Remote Entry Module (SKREEM)
receives an encrypted Radio Frequency (RF) signal
from the transponder key. The SKREEM then
decrypts the signal and broadcasts the requested
remote commands to the appropriate modules in the
vehicle over the Programmable Communication
Interface (PCI) data bus. A valid transponder key ID
must be incorporated into the RF signal in order for
the SKREEM to pass the message on to the appro-
priate modules.
Automatic transponder key synchronization is done
by the SKREEM if a valid transponder key is
inserted into the ignition cylinder, and the ignition is
turned ON. This provides a maximum operation win-
dow for RKE functions.
Each Sentry Key Remote Entry System (SKREES)
consists of a SKREEM and a transponder key. Each
system has a secret key code unique to that system.
The secret key is electronically coded in the
SKREEM and in all programmed transponder keys.
It is used for immobilization and RKE functions for
data security. In addition, each transponder key will
have a unique identification. For North America, the
options are a 3-button or 6 button integrated keys.
For Export, the options are 2-button or 5 button key
fobs. (Export does not get the integrated key).
8Q - 4 VEHICLE THEFT SECURITYRS
SENTRY KEY REMOTE ENTRY MODULE (Continued)

When the ignition switch is moved to the RUN
position, the SKREEM transmits an Radio Frequency
(RF) signal to the transponder in the ignition key.
The SKREEM then waits for a response RF signal
from the transponder in the key. If the response
received identifies the key as valid, the SKREEM
sends a9valid key9message to the Powertrain Con-
trol Module (PCM) over the Programmable Commu-
nication Interface (PCI) data bus. If the response
received identifies the key as invalid or no response
is received from the transponder in the ignition key,
the SKREEM sends an9invalid key9message to the
PCM. The PCM will enable or disable engine opera-
tion based upon the status of the SKREEM mes-
sages. It is important to note that the default
condition in the PCM is9invalid key.9Therefore, if no
response is received by the PCM, the engine will be
immobilized after two (2) seconds of running.
The SKREEM also sends indicator light status
messages to the Mechanical Instrument Cluster
(MIC) to operate the light. This is the method used to
turn the light ON solid or to flash it after the indi-
cator light test is complete to signify a fault in the
SKREES. If the light comes ON and stays ON solid
after the indicator light test, this signifies that the
SKREEM has detected a system malfunction and/or
that the SKREES has become inoperative. If the
SKREEM detects an invalid keyORa key-related
fault exists, the indicator light will flash following
the indicator light test. The SKREEM may also
request an audible chime if the customer key pro-
gramming feature is available and the procedure is
being utilized (Refer to 8 - ELECTRICAL/VEHICLE
THEFT SECURITY/TRANSPONDER KEY - STAN-
DARD PROCEDURE).
REMOTE KEYLESS ENTRY (RKE)
After pressing the lock button on the RKE trans-
mitter, all of the door locks will lock, the illuminated
entry will turn off (providing all doors are closed),
and the VTSS (if equipped) will arm. After pressing
the unlock button, on the RKE transmitter, one time,
the driver door lock will unlock, the illuminated
entry will turn on the courtesy lamps, and the VTSS
(if equipped) will disarm. After pressing the unlock
button a second time, the remaining door locks will
unlock. The Electronic Vehicle Information Center
(EVIC) or the DRBIIItscan tool can reprogram this
feature to unlock all of the door locks with one press
of the unlock button. If the vehicle is equipped with
the memory system, the memory message will iden-
tify which transmitter (1 or 2) sent the signal.The SKREEM is capable of retaining up to 8 indi-
vidual access codes (8 transmitters). If the PRNDL is
in any position except park, the SKREEM will dis-
able the RKE. The 4 button transmitter uses
1-CR2032 battery. The minimum battery life is
approximately 4.7 years based on 20 transmissions a
day at 84ÉF (25ÉC). Use the DRBIIItscan tool or the
Miller Tool 9001 RF Detector to test the RKE trans-
mitter. Use the DRBIIItor the customer program-
ming method to program the RKE system. However,
the SKREEM will only allow RKE programming
when the ignition is in the ON position, the PRNDL
is in park position, and the VTSS (if equipped) is dis-
armed.
TIRE PRESSURE MONITORING (TPM)

OPERATION
When rear wiper operation is required, the BCM
will provide ignition ON voltage to the rear wiper
motor. When the wiper switch is turned OFF, the
BCM provides circuit ground to operate the motor
until the wipe cycle is complete and the wiper arm
returns to the base of the rear window.
The rear wiper/washer switch only offers an inter-
mittent rear wiper mode. The wiper motor will cycle
every 7 seconds. The intermittent delay time is also
adjusted based upon vehicle speed. With the vehicle
traveling greater than 50 mph, the cycle changes to
every 5 seconds.
When rear washer is requested by depressing and
holding down the switch, the BCM then provides a
ground for the rear washer motor. Until the switch is
released, the motor will be in a continuous wipe
mode, then return to an intermittent wipe mode.
