SERVO
DESCRIPTION
The servo unit consists of a solenoid valve body,
and a vacuum chamber. The solenoid valve body con-
tains three solenoids:
²Vacuum
²Vent
²Dump
The vacuum chamber contains a diaphragm with a
cable attached to control the throttle linkage.
OPERATION
The PCM controls the solenoid valve body. The
solenoid valve body controls the application and
release of vacuum to the diaphragm of the vacuum
servo. The servo unit cannot be repaired and is ser-
viced only as a complete assembly.
Power is supplied to the servo by the PCM through
the brake switch. The PCM controls the ground path
for the vacuum and vent solenoids.
The dump solenoid is energized anytime it receives
power. If power to the dump solenoid is interrupted,
the solenoid dumps vacuum in the servo. This pro-
vides a safety backup to the vent and vacuum sole-
noids.
The vacuum and vent solenoids must be grounded
by the PCM to operate. When the PCM grounds the
vacuum servo solenoid, the solenoid allows vacuum
to enter the servo and pull open the throttle plate
using the cable. When the PCM breaks the ground,
the solenoid closes and no more vacuum is allowed to
enter the servo. The PCM also operates the vent sole-
noid via ground. The vent solenoid opens and closes a
passage to bleed or hold vacuum in the servo as
required.
The PCM cycles the vacuum and vent solenoids to
maintain the set speed, or to accelerate and deceler-
ate the vehicle. To increase throttle opening, the
PCM grounds the vacuum and vent solenoids. To
decrease throttle opening, the PCM removes the
grounds from the vacuum and vent solenoids.
REMOVAL
(1) Release hood latch and open hood.
(2) Disconnect the negative battery cable.
(3) Disconnect the throttle and speed control cable
ends from throttle body (Fig. 2).

VEHICLE THEFT SECURITY
DESCRIPTION
VEHICLE THEFT SECURITY SYSTEM
The Vehicle Theft Security System (VTSS) is
designed to protect against whole vehicle theft. The
system monitors vehicle doors, and ignition action for
unauthorized operation (hood and liftgate for RG -
Export). The alarm activates:
²Sounding of the horn
²Flashing of the headlamps/park/tail lamps
²Flashing of the headlamps
²An engine kill feature (with SKREES)
SENTRY KEY REMOTE ENTRY SYSTEM
The Sentry Key Remote Entry System (SKREES)
is available as a factory-installed option on this vehi-
cle. It is designed to provide passive protection
against unauthorized vehicle use by disabling the
engine, after two (2) seconds of running, whenever an
invalid key is used to start the vehicle. The SKIS is
active whenever the ignition is on and does not
require any customer intervention. The primary com-
ponents of the system are the Sentry Key Remote
Entry Module (SKREEM), Sentry Key (integrated
key with tranponder and RKE on a circuit board),
indicator light, Body Control Module (BCM), and the
Powertrain Control Module (PCM). The SKREEM is
mounted to the steering column with the molded,
integral antenna mounted on the ignition housing.
The indicator light, is located in the Mechanical
Instrument Cluster (MIC).
OPERATION
VEHICLE THEFT SECURITY SYSTEM
Upon failure of proper Sentry Key Remote Entry
Module (SKREEM) communication to the PCM, the
PCM will shut off fuel after two seconds of run time.
The engine will not re-crank on the key cycle that
the failure occurred, a full key down sequence must
be performed for the engine to crank again. After six
consecutive fuel shut-offs, the engine will no longer
crank on subsequent key cycles. The failure must be
corrected and a valid communication process between
the SKREEM and the PCM must occur for the
engine to crank and start again.
The electronics for the VTSS are part of the Body
Control Module (BCM). The system is armed when
the vehicle is locked using the:
²Power door lock switches (with any door ajar)
²Remote Keyless Entry integrated key.
²Door Cylinder Lock Switches (RG only).
For vehicles equipped with Sentry Key Remote
Entry System (SKREES), the doors do not have to be
locked to enable the fuel shut off feature.
After the vehicle is locked and the last door is
closed, the set LED indicator in the Mechanical
Instrument Cluster (MIC) will flash quickly for 16
seconds, indicating that arming is in progress. If no
monitored systems are activated during this period,
the system will arm. The LED will extinguish unless
the liftgate is open. If the liftgate is open, the LED
will flash at a slower rate. This indicates that the
system is armed.
RSVEHICLE THEFT SECURITY8Q-1

RG Only- If fault is detected on the driver key
cylinder input, the indicator LED will remain solid
during the arming process, although the system will
still arm.
If the indicator LED does not illuminate at all
upon door closing it indicates that the system is not
arming.
Passive disarming occurs upon normal vehicle
entry by unlocking either door with the remote trans-
mitter (RG - ignition key or remote transmitter). This
disarming will also halt the alarm once it has been
activated.
A tamper alert exists to notify the driver that the
VTSS had been activated. This alert consists of 3
horn pulses when the vehicle is disarmed.
NOTE: The VTSS will not arm by pushing down the
door lock mechanism. This will manually override
the system.
RG Only- For Door Cylinder Lock Switch
Removal and Installation, refer to Electrical, Power
Locks, Door Cylinder Lock Switch.
If the VTSS is triggered, the horn will pulse, head-
lamps/marker lamps will flash, and the VTSS warn-
ing lamp will flash. If BCM determines the threat to
be false and the VTSS is not triggered again, the sys-
tem will shut down and rearm itself after three min-
utes. If a trigger is still active, the alarm will
continue for an additional 15 minutes without the
horn. The VTSS monitors the passenger compart-
ment (for RG - Export it also monitors the engine
compartment. If a malfunction occurs in the engine
compartment, the passenger compartment would still
arm and function normally).
NOTE: System will not arm if passenger compart-
ment is not secure.
NOTE: (RG - Export - If hood is not secure during
the arming sequence, the lamp will stay lit and not
flash. The system will arm with hood not secured
and the liftgate open).
ARMING THE VTSS - METHOD A
(1) With the key removed from the ignition lock
and any door open (excluding liftgate), actuate one of
the following:
²Power door lock button to LOCK,
²Key fob LOCK button
²Driver door lock key cylinder to locked position
(RG Only).
(2) Close all opened doors. Liftgate can remain
open.(3) After the last door is closed, an arming time-
out period of sixteen seconds will start, then the
VTSS will become armed.
ARMING THE VTSS - METHOD B
Actuating the key fob transmitter LOCK button,
key locking the front doors with the doors closed and
the ignition locked will begin the arming time-out
period. If method A, 16 second time-out sequence was
in process when method B was actuated, the 16 sec-
ond time-out will restart from the time of the second
actuation.
If the security lamp does not illuminate at all upon
final door closure, it indicates that the system is not
arming.
The current VTSS status armed or disarmed shall
be maintained in memory to prevent battery discon-
nects from disarming the system.
TRIGGERING THE VTSS
After the VTSS is armed, the following actions will
trigger the alarm:
²Opening any door (liftgate - only if opening via
liftgate button on key fob).
²Opening the hood (RG - Export)
²Turning the ignition to the RUN position.
NOTE: When the VTSS is ARMED, the interior
power door lock switch ªUNLOCKº will be disabled
until the vehicle is disarmed.
CAUTION: The VTSS indicator LED will trigger and
engine will continue to run if the vehicle is
equipped with SKREES and the proper key is used
to start the vehicle. This condition will occur if the
VTSS has been triggered. If valid key is used, VTSS
will disarm
SENTRY KEY REMOTE ENTRY SYSTEM
The SKREES includes keys from the factory which
are pre-programmed. Each SKREEM will recognize a
maximum of eight Sentry Keys. If the customer
would like to own additional keys other than those
provided with the vehicle, they can be purchased
from any authorized dealer. These keys must be pro-
grammed to the SKREEM on the vehicle in order for
the system to recognize them as valid keys. This can
be done by the dealer with a DRBllltscan tool or by
a customer if this feature is available in their market
and they have two (2) valid keys already available to
them. Refer to the Service Procedures portion of this
system for additional details. The SKREES performs
a self-test each time the ignition switch is turned to
the ON position and will store Diagnostic Trouble
Codes (DTC's) if a system malfunction is detected.
8Q - 2 VEHICLE THEFT SECURITYRS
VEHICLE THEFT SECURITY (Continued)

The SKREES can be diagnosed and any stored DTC's
can be retrieved using a DRBllltscan tool as
described in the appropriate Body Diagnostic Proce-
dures information.

REMOTE ENTRY SYSTEM
WARNING: On vehicles equipped with airbags, refer
to electrical, restraints, warnings, before attempting
component diagnosis or service. Failure to take the
proper precautions could result in accidental airbag
deployment and possible personal injury or death.
NOTE: The following tests may not prove conclu-
sive in the diagnosis of this system. The most reli-
able, efficient, and accurate means to diagnose the
Sentry Key Remote Entry System (SKREES)
involves the use of a DRBIIITscan tool. Refer to the
proper Body Diagnostic Procedures information.
The Sentry Key Remote Entry System (SKREES)
and the Programmable Communication Interface
(PCI) bus network should be diagnosed using a scan
tool. The scan tool will allow confirmation that the
PCI bus is functional, that the Sentry Key Remote
Entry Module (SKREEM) is placing the proper mes-
sages on the PCI bus, and that the Powertrain Con-
trol Module (PCM) is receiving the PCI bus
messages. Refer to the proper Body Diagnostic Proce-
dures information, and Wiring Diagrams for complete
circuit descriptions and diagrams.
(1) Check the fuses in the Integrated Power Mod-
ule (IPM). If OK, go to Step 2. If not OK, repair the
shorted circuit or component as required and replace
the faulty fuse.
(2) Disconnect and isolate the battery negative
remote cable from the remote terminal. Unplug the
wire harness connector at the SKREEM. Check for
continuity between the ground circuit cavity of the
SKREEM wire harness connector and a good ground.
There should be continuity. If OK, go to Step 3. If not
OK, repair the open circuit to ground as required.
(3) Connect the battery negative cable. Check for
battery voltage at the fused B(+) circuit cavity of the
SKREEM wire harness connector. If OK, go to Step
4. If not OK, repair the open circuit to the fuse in the
IPM as required.
(4) Turn the ignition switch to the ON position.
Check for battery voltage at the fused ignition switch
output (run/start) circuit cavity of the SKREEM wire
harness connector. If OK, use a scan tool and the
proper Body Diagnostic Procedures information tocomplete the diagnosis of the SKREES. If not OK,
repair the open circuit to the fuse in the IPM as
required.

SENTRY KEY REMOTE ENTRY
MODULE
DESCRIPTION
The Sentry Key Remote Entry Module (SKREEM)
performs the functions of the Sentry Key Immobilizer
Module (SKIM), Remote Keyless Entry (RKE) Mod-
ule, and the Tire Pressure Monitoring (TPM) System
(previously part of the Electronic Vehicle Information
Center (EVIC).
The SKREEM is located in the same location as
the SKIM was and is mounted the same way. It looks
identical, but has added capabilities.
SENTRY KEY IMMOBILIZER
The Sentry Key Immobilizer System (SKIS)
authenticates an electronically coded Transponder
Key placed into the ignition and sends a valid/invalid
key message to the Powertrain Control Module
RSVEHICLE THEFT SECURITY8Q-3
VEHICLE THEFT SECURITY (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)
The SKREEM monitors the signals from the tire
pressure sensor/transmitters and determines if any
tire has gone below the low pressure threshold LOW
TIRE PRESSURE THRESHOLDS table.
LOW TIRE PRESSURE THRESHOLDS
SYSTEM STATUS
INDICATORTIRE PRESSURE

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.
