KNEE BLOCKER AIRBAG
DESCRIPTION
The Knee Blocker Airbag (Fig. 29) is located on the
driver side of the vehicle beneath the instrument
panel under steering column cover (Fig. 30).
The knee blocker airbag includes one reaction plate
and one load plate, within which the cushion and
inflator are mounted and sealed. Following a knee
blocker airbag deployment, the knee blocker airbag
and instrument panel assembly must be replaced.
Refer to the proper diagnostic information for diagno-
sis and testing.
OPERATION
The knee blocker airbag is equipped with a single
inflator. When the Occupant Restraint Controller
(ORC) sends the proper electrical signals to the initi-
ator, the electrical energy generates enough heat to
initiate a small pyrotechnic charge which, in turn
ignites chemical pellets within the inflator. Once
ignited, these chemical pellets burn rapidly and pro-
duce a large quantity of inert gas. The inflator is
sealed to the back of the airbag housing and a dif-
fuser in the inflator directs all of the inert gas into
the airbag cushion, causing the cushion to inflate. As
the cushion inflates, the knee blocker airbag trim
deploy. Following an airbag deployment, the airbag
cushion quickly deflates by venting the inert gas
towards the instrument panel through vent holes
within the fabric used to construct the back panel of
the airbag cushion.
Some of the chemicals used to create the inert gas
may be considered hazardous while in their solid
state before they are burned, but they are securely
sealed within the airbag inflator. Typically, the poten-
tially hazardous chemicals are burned during an air-
bag deployment event.
WARNING: The inert gas that is produced when the
chemicals are burned is harmless. However, a small
amount of residue from the burned chemicals may
cause some temporary discomfort if it contacts the
skin, eyes, or breathing passages. If skin or eye irri-
tation is noted, rinse the affected area with plenty
of cool, clean water. If breathing passages are irri-
tated, move to another area where there is plenty of
clean, fresh air to breath. If the irritation is not alle-
viated by these actions, contact a physician.

IMPACT SENSOR (Continued)

anchor. The OCM then monitors the return voltage
from each of the sensors. The bladder pressure sen-
sor input allows the OCM to determine whether the
passenger front seat is occupied and the relative size
of the occupant by providing a weight-sensing refer-
ence to the load on the seat cushion. The belt tension
sensor provides an additional logic input to the OCM
microprocessor that allows it to distinguish between
the lower seat belt cinch loads of a belted occupant
and the higher loads associated with a belted child
seat.
Pre-programmed decision algorithms and OCS cal-
ibration allow the OCM microprocessor to determine
when the seat cushion load as signaled by the blad-
der pressure sensor and the seat belt cinch load as
signaled by the belt tension sensor indicate that pas-
senger airbag protection is appropriate. When the
programmed conditions are met, the OCM sends the
proper electronic occupant classification messages
over the PCI data bus to the Occupant Restraint
Controller (ORC), and the ORC enables or disables
the deployment circuits for the passenger front sup-
plemental restraints. The ORC also provides a con-
trol output for the Passenger Airbag Disabled (PAD)
indicator in the instrument panel center stack, based
upon the electronic occupant classification messages
it receives from the OCM.
The OCM microprocessor continuously monitors all
of the OCS electrical circuits and components to
determine the system readiness. If the OCM detects
a monitored system fault, it sets an active and stored
Diagnostic Trouble Code (DTC) and sends the appro-
priate electronic messages to the ORC over the PCI
data bus. Then the ORC sets a DTC and sends mes-
sages to control the airbag indicator operation
accordingly. An active fault only remains for the
duration of the fault, or in some cases for the dura-
tion of the current ignition switch cycle, while a
stored fault causes a DTC to be stored in memory by
the OCM and the ORC. For some DTC's, if a fault
does not recur for a number of ignition cycles, the
OCM will automatically erase the stored DTC. For
other internal faults, the stored DTC is latched for-
ever.
The OCM receives battery current from an IPM
high side driver (Run/Start). The OCM receives
ground through a ground circuit of the body wire
harness, which it shares with the ORC. These con-
nections allow the OCM to be operational whenever
the ignition switch is in the Start or ON positions.
To diagnose and test the OCS, use a scan tool and
the appropriate diagnostic information.
REMOVAL
Once any of the original factory-installed compo-
nents except the Occupant Classification Module(OCM) have been replaced with the service replace-
ment package components, the OCM can only be ser-
viced by replacing the entire passenger front seat
cushion unit with another complete service replace-
ment package (Refer to 23 - BODY/SEATS/SEAT
CUSHION - FRONT - REMOVAL).
WARNING: Never replace both the Occupant
Restraint Controller (ORC) and the Occupant Clas-
sification Module (OCM) at the same time. If both
require replacement, replace one, then perform the
Airbag System test (Refer to 8 - ELECTRICAL/RE-
STRAINTS - DIAGNOSIS AND TESTING - AIRBAG
SYSTEM) before replacing the other. Both the ORC
and the OCM store Occupant Classification System
(OCS) calibration data, which they transfer to one
another when one of them is replaced. If both are
replaced at the same time, an irreversible fault will
be set in both modules and the OCS may malfunc-
tion and result in personal injury or death.
(1) Disconnect and isolate the battery negative
cable.
(2)
WARNING: Wait two minutes for the airbag system
reserve capacitor to discharge before beginning
any airbag system or component service. Failure to
do so may result in accidental airbag deployment,
personal injury or death.
(3) Reach under the front edge of the passenger
side front seat cushion to access and remove the lock
pin from the connector lock tower on the Occupant
Classification Module (OCM) (Fig. 36).
(4) Disconnect the passenger front seat wire har-
ness connector for the OCM.
(5) Remove the two screws that secure the OCM to
the OCM bracket.
(6) Remove the OCM from under the passenger
front seat.
INSTALLATION
WARNING: To avoid personal injury or death on
vehicles equipped with the Occupant Classification
System (OCS), only the Occupant Classification
Module (OCM) and the seat cushion trim may be
serviced separately. All other components of the
passenger front seat cushion must be serviced only
as a complete factory-calibrated, assembled and
tamper-evident service replacement package.
Once any of the original factory-installed compo-
nents except the OCM have been replaced with the
service replacement package components, the OCM
can only be serviced by replacing the entire passen-

NOTE: Turning the system off by depressing the
OFF switch or turning off the ignition switch will
erase the set speed stored in the PCM.
For added safety, the speed control system is pro-
grammed to disengage for any of the following condi-
tions:
²An indication of Park or Neutral
²A rapid increase rpm (indicates that the clutch
has been disengaged)
²Excessive engine rpm (indicates that the trans-
mission may be in a low gear)
²The speed signal increases at a rate of 10 mph
per second (indicates that the co-efficient of friction
between the road surface and tires is extremely low)
²The speed signal decreases at a rate of 10 mph
per second (indicates that the vehicle may have
decelerated at an extremely high rate)
²If the actual speed is greater than 20 mph over
the set speed.
²Autostick shifts into 1st or 2nd gear (autostick,
if equipped)
Once the speed control has been disengaged,
depressing the RESUME switch when speed is
greater than 20 mph allows the vehicle to resume
control to the target speed that was stored in the
PCM.
While the speed control is engaged, the driver can
increase the vehicle speed by depressing the ACCEL
switch. The new target speed is stored in the PCM
when the ACCEL switch is released. The PCM also
has a9tap-up9feature in which target speed
increases by 2 mph for each momentary switch acti-
vation of the ACCEL switch. The PCM also provides
a means to decelerate to a new lower target speed
without disengaging speed control. Depress and hold
the COAST switch until the desired speed is reached,
then release the switch.
The PCM also has a ªTap Downº feature in which
target speed decreases at 1 mph for each momentary
switch activation of the coast switch.
OPERATION - INTERACTIVE SPEED CONTROL
(4 Speed EATX Only)
Interactive means that communication between the
PCM and the TCM is taking place, this communica-
tion is internal to the PCM on NGC vehicles. Inter-
active speed control avoids unnecessary shifting for
smoother, quieter operation and when downshifts are
required, makes the shifts smoother.
CLIMBING A GRADE
DESCRIPTION
When climbing a grade the interactive speed con-
trol tries to maintain the set speed by increasing thethrottle opening, while inhibiting/delaying down-
shifts.
OPERATION
If opening the throttle alone cannot maintain the
set speed and the vehicle speed drops more than
three mph below the set speed, the transmission will
downshift to third gear. If the vehicle continues to
lose speed, by more than 6 mph, the transmission
will downshift again to maintain the set speed. After
the vehicle encounters a less-steep grade, or has
crested the grade (reduced the load on the power-
train) and can maintain the set speed at a reduced
throttle position, the transmission will upshift, as
appropriate, until the set speed can be maintained in
Overdrive.
GRADE HUNTING
DESCRIPTION
All vehicles equipped with a four speed automatic
transmission have a grade hunting feature for the
2nd to 3rd gear upshift and the 3rd to Overdrive
upshift.
OPERATION
The PCM on NGC vehicles identifies the power-
train loading conditions and selects the proper gear
to maintain the current vehicle speed. Under moder-
ate loading conditions the transaxle will stay in 3rd
gear until the top of the grade is reached or the pow-
ertrain loading is reduced.
If powertrain loading is severe, the transaxle may
shift into 2nd gear and remain there until power-
train loading is reduced, then a 2nd to 3rd gear
upshift will be scheduled. Grade hunting features
always operate regardless of whether or not the
interactive speed control is engaged.If the interac-
tive speed control is not engaged and power-
train loading is not reduced, the driver may
have to completely lift off of the throttle before
an upshift will occur. If the driver does lift off the
throttle to induce an upshift under these conditions,
vehicle speed will reduce and the Overdrive to 3rd
and 3rd to 2nd gear downshifts will reoccur when the
throttle is reapplied. If grade hunting is repeatedly
induced by the driver, transaxle damage may result.
AUTOMATIC SPEED CONTROL OVERSPEED
REDUCTION
DESCRIPTION
Transmission control software includes an auto-
matic speed control overspeed reduction feature. This
maintains vehicle speed at the selected set point
when descending a grade.

(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).

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)

TRANSPONDER KEY
DESCRIPTION
The Sentry Key Remote Entry System (SKREES)
uses a transponder chip that is integral to the circuit
board of the integrated ignition key (SKREES and
RKE incorporated) to communicate with the Sentry
Key Remote Entry Module (SKREEM). Ignition keys
are supplied with the vehicle when it is shipped from
the factory.
For export vehicles equipped with SKREES, the
transponder chip is undermolded within the head of
the key.
OPERATION
Each Sentry Key has a unique transponder identi-
fication code permanently programmed into it by the
manufacturer. Likewise, the Sentry Key Remote
Entry Module (SKREEM) has a unique9Secret Key9
code programmed into it by the manufacturer as
well. When a Sentry Key is programmed into the
memory of the SKREEM, the SKREEM stores the
transponder identification code from the Sentry Key,
and the Sentry Key learns the9Secret Key9code from
the SKREEM. Once the Sentry Key learns the
9Secret Key9code of the SKREEM, it is also perma-
nently programmed into the transponder's memory.
Therefore, blank keys for the Sentry Key Remote
Entry System (SKREES) must be programmed by
the SKREEM in addition to being cut to match the
mechanical coding of the ignition lock cylinder. Refer
to Electrical, Vehicle Theft Security, Transponder
Key, Standard Procedure - Transponder Program-
ming.
The Sentry Key's transponder is within the range
of the SKREEM's transceiver antenna ring when it is
inserted into the ignition lock cylinder. When the
ignition switch is turned to the ON position, the
SKREEM communicates with the Sentry Key via a
radio frequency (RF) signal. The SKREEM deter-
mines if a valid key is present based on the informa-
tion it receives from the Sentry Key. If a valid key is
detected, that fact is communicated to the PCM via
the PCI bus and the vehicle is allowed to continue
running. If an invalid key is received by the PCM or
no status at all is communicated, the vehicle will
stall after two (2) seconds of running. The indicator
light will be flashing at this point. The Sentry Key's
transponder can not be repaired. If it is faulty or
damaged, it must be replaced.
Common communication problems:
²Two transponder keys too close together.
²Speed Pass too close to transponder key.
Solid indicator that there is a system failure.
²Loss of PCM communication.
²Failed antenna circuit.

OPERATION
FRONT WIPER/WASHER SYSTEM
The windshield washer circuit is protected by a 15
amp Cartridge Fuse located in the IPM. The wiper
motor has permanent magnetic fields. The speeds are
determined by current flow to the appropriate set of
brushes inside the motor. The current flow is con-
trolled by the multi-function switch. The high speed/
low speed relays are located in the IPM. The speed
sensitive intermittent wiper is controlled by the Body
Control Module (BCM). The intermittent mode, with
the vehicle traveling greater than 10.4 mph, has a
range of 0.5 to 18 seconds. With the vehicle traveling
less than 10.4 mph, the time delay doubles to a
range of 1 to 36 seconds. The wiper arms will park at
the base of the windshield just above the cowl cover
after the wiper switch is turned OFF.
The windshield wiper motor and linkage is located
in an integral wiper unit at the rear of the engine
compartment. The wiper unit must be removed to
gain access to the wiper motor.
The front and rear washer systems share the same
washer pump motor.
REAR WIPER/WASHER SYSTEM
When rear wiper operation is required, the BCM
will provide ignition ON voltage to the rear wiper
motor (Export and ATC equipped vehicles only).
When the wiper switch is turned OFF, the BCM pro-
vides circuit ground to operate the motor until the
wipe cycle is complete and the wiper arm returns to
the base of the rear window.
Switch only offers an intermittent 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 washer motor. Until the switch is
released, the motor will be in a continuous wipe
mode, then return to an intermittent wipe mode.

DESCRIPTION
TELECOMMUNICATIONS
A hands-free cellular system is an available option
on this vehicle. It uses BluetoothŸ technology to pro-
vide wireless communication between the operator's
compatible cellular telephone and the vehicle's
on-board receiver.
The system uses voice recognition technology to
control operation. The incoming voice is broadcast
through the vehicle's radio speakers, automatically
overriding any other audio signals on the speakers
when the hands-free system is in use. A microphone
in the rearview mirror picks up vehicle occupant's
voices. If a call is in progress when the ignition is
switched off, the hands-free system will continue to
operate for up to 45 seconds as part of the Accessory
Relay Delay function. Thereafter, the call can con-
tinue on the hand-held telephone.
The center console front storage compartment
includes a cellular telephone holder, but the system
will communicate with a telephone that is anywhere
within the vehicle. However, covering the hand held
phone or the hands-free phone module with a metal
object may block the signal. The system will recog-
nize up to seven telephones, each of which is given a
spoken identification by the user during the setup
process. The system includes Spanish voice recogni-
tion in addition to English.
Two buttons on the rearview mirror, identified with
ISO icons, control the system: A9phone9button turns
the system on and off; a9voice recognition9(or voice
command) button prompts the hands-free system to
listen for a voice command.
OPERATION
TELECOMMUNICATION
Two buttons on the rearview mirror, identified with
ISO icons, control the system: A9phone9button turns
the system on and off; a9voice recognition9(or voice
command) button prompts the hands-free system to
listen for a voice command. The system includes the
following features:
²Phonebook - Stores telephone numbers for later
recall by name or other verbal identification, called a
voice tag, and memory location.
²Four memory locations - Home, Work, Mobile
and Pager. A maximum of 32 unique names or voice
tags may be stored at the same time, with a different
number in each of the four memory locations.
²Voice tag dialing - Dials the number associated
with a voice tag and memory location.
²Digit dialing - Dials the telephone number by
recognizing the names of the digits as they are spo-
ken.
²Receiving calls - A voice prompt notifies the user
of an incoming call. Pressing the ªphoneº button
answers the call.
²Privacy Mode - Switches the call to the hand-
held telephone and the hands-free system and back
again using the ªvoice recognitionº (or ªvoice com-
mandº) button and a voice command, if desired.
DIAGNOSIS AND TESTING
