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

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.
STANDARD PROCEDURE - TRANSPONDER
PROGRAMMING
USING A DRBIIITSCAN TOOL
All Sentry Keys included with the vehicle are pre-
programmed to work with the Sentry Key Remote
Entry System (SKREES) when it is shipped from the
factory. The Sentry Key Remote Entry Module
(SKREEM) can be programmed to recognize up to a
total of eight Sentry Keys. When programming a
blank Sentry Key transponder, the key must first be
cut to match the ignition lock cylinder of the vehicle
for which it will be used. The vehicle's four digit PIN

IOD FUSE
DESCRIPTION
All vehicles are equipped with an Ignition-Off
Draw (IOD) fuse that is removed from its normal
cavity in the Integrated Power Module (IPM) when
the vehicle is shipped from the factory. Dealer per-
sonnel are to remove the IOD fuse from the storage
location and install it into the IPM fuse cavity
marked IOD as part of the preparation procedures
performed just prior to new vehicle delivery.
The IOD fuse is a 20 ampere blade-type mini fuse
and, when removed, it is stored in a fuse cavity adja-
cent to the washer fuse within the IPM.
OPERATION
The term ignition-off draw (IOD) identifies a nor-
mal condition where power is being drained from the
battery with the ignition switch in the Off position.
The IOD fuse feeds the memory and sleep mode func-
tions for some of the electronic modules in the vehicle
as well as various other accessories that require bat-
tery current when the ignition switch is in the Off
position, including the clock. The only reason the
IOD fuse is removed is to reduce the normal IOD of
the vehicle electrical system during new vehicle
transportation and pre-delivery storage to reduce
battery depletion, while still allowing vehicle opera-
tion so that the vehicle can be loaded, unloaded and
moved as needed by both vehicle transportation com-
pany and dealer personnel.
The IOD fuse is removed from the Integrated
Power Module (IPM) fuse cavity when the vehicle is
shipped from the assembly plant. Dealer personnel
must install the IOD fuse when the vehicle is being
prepared for delivery in order to restore full electrical
system operation. Once the vehicle is prepared for
delivery, the IOD function of this fuse becomes trans-
parent and the fuse that has been assigned the IOD
designation becomes only another Fused B(+) circuit
fuse. The IOD fuse serves no useful purpose to the
dealer technician in the service or diagnosis of any
vehicle system or condition, other than the same pur-
pose as that of any other standard circuit protection
device.
The IOD fuse can be used by the vehicle owner as
a convenient means of reducing battery depletion
when a vehicle is to be stored for periods not to
exceed approximately thirty days. However, it mustbe remembered that removing the IOD fuse will not
eliminate IOD, but only reduce this normal condition.
If a vehicle will be stored for more than thirty days,
the battery negative cable should be disconnected to
eliminate normal IOD; and, the battery should be
tested and recharged at regular intervals during the
vehicle storage period to prevent the battery from
becoming discharged or damaged.
POWER OUTLET
DESCRIPTION
Two power outlets are installed in the instrument
panel center lower bezel. Two additional power out-
lets are incorporated into the left rear C-pillar and
the center console (if equipped). The power outlets
bases are secured by a snap fit. A hinged plug flips
closed to conceal and protect the power outlet base
when not in use.
OPERATION
The power outlet base or receptacle shell is con-
nected to ground, and an insulated contact in the
bottom of the shell is connected to battery current.
The power outlet on the instrument panel marked
with a battery receives battery voltage from a fuse in
the Integrated Power Module (IPM) at all times. The
other power outlet on the instrument panel marked
with a key receives battery voltage only when the
key is in the on position.
The power outlet located in the center console
receives battery voltage all the time when positioned
between thefront seatsand key-on voltage when
positioned between therear seats. The power outlet
located on the C-pillar receives battery voltage only
when the key is in the ON position.

nuity between the ground circuit cavity of the power
outlet wire harness connector and a good ground.
There should be continuity. If OK, go to Step 6. If not
OK, repair the open ground circuit to ground as
required.
(6) Connect the battery negative cable. Check for
battery voltage at the fused B(+) circuit cavity of the
power outlet wire harness connector. If OK, replace
the faulty power outlet receptacle. If not OK, repair
the open fused B(+) circuit to the IPM fuse as
required.
REMOVAL
(1) Disconnect and isolate the battery negative
cable.
(2) Note position of the retaining bosses (Fig. 4).
(3) Using external snap ring pliers with 90 degree
tips. Insert pliers with tips against bosses and
squeeze forcing bosses out of base.
(4) Pull out the base through mounting ring by
gently rocking pliers.
(5) Disconnect the base wires.
(6) Remove light ring and disconnect wire.
INSTALLATION
(1) Position the mounting ring on the instrument
panel and feed the wires through the ring. Index thecap and the mounting ring with the index tab at the
9 o'clock position to the key in the instrument panel.
Install the ring.
(2) Connect the wires to the base. Orientate the
base alignment rib at the 11 o'clock position to mate
the groove in the mounting ring to the base.
(3) Push the base into the bezel until it locks in
place.
(4) Check operation of outlet or element and
install the outlet cap.

FUEL DELIVERY
DESCRIPTION
DESCRIPTION
The front wheel drive car uses a plastic fuel tank
located rear center of the vehicle.
The Fuel Delivery System consists of: the following
items:
²Electric fuel pump module
²Fuel filter
²Tubes/lines/hoses
²Fuel injectors
The in-tank fuel pump module contains the fuel
pump. The pump is serviced as part of the fuel pump
module. Refer to Fuel Pump Module.
The fuel filter is replaceable only as part of the
fuel pump module.
DESCRIPTION - FFV REPLACEMENT PARTS
Many components in a Flexible Fuel Vehicle (FFV)
are designed to be compatible with ethanol. Always
be sure that the vehicle is serviced with correct etha-
nol compatible parts.
CAUTION: Replacing fuel system components with
non-ethanol compatible components can damage
your vehicle and may void the warranty.
OPERATION
The fuel system provides fuel pressure by an
in-tank pump module. The Powertrain Control Mod-
ule (PCM) controls the operation of the fuel system
by providing battery voltage to the fuel pump
through the fuel pump relay. The PCM requires only
three inputs and a good ground to operate the fuel
pump relay. The three inputs are:
²Ignition voltage
²Crankshaft Position (CKP) sensor
²Camshaft Position (CMP) sensor

(Refer to Appropriate Diagnostic Information)
STANDARD PROCEDURE
STANDARD PROCEDURE - FUEL SYSTEM
PRESSURE RELEASE PROCEDURE
(1) Remove Fuel Pump relay from Power Distribu-
tion Center (PDC). For location of relay, refer to label
on underside of PDC cover.
(2) Start and run engine until it stalls.(3) Attempt restarting engine until it will no
longer run.
(4) Turn ignition key to OFF position.
(5) Return fuel pump relay to PDC.
(6) One or more Diagnostic Trouble Codes (DTC's)
may have been stored in PCM memory due to fuel
pump relay removal. The DRB IIItscan tool must be
used to erase a DTC.
STANDARD PROCEDURE - DRAINING FUEL
TANK
Two different procedures may be used to drain fuel
tank (lowering tank or using DRBIIItscan tool).
The quickest draining procedure involves lowering
the fuel tank.
WARNING: RELEASE FUEL SYSTEM PRESSURE
BEFORE SERVICING FUEL SYSTEM COMPONENTS.
SERVICE VEHICLES IN WELL VENTILATED AREAS
AND AVOID IGNITION SOURCES. NEVER SMOKE
WHILE SERVICING THE VEHICLE. THIS MAY
RESULT IN PERSONAL INJURY OR DEATH.
As an alternative procedure, the electric fuel pump
may be activated allowing tank to be drained at fuel
rail connection. Refer to DRBIIItscan tool for fuel
pump activation procedures. Before disconnecting
fuel line at fuel rail, release fuel pressure. Refer to
the Fuel System Pressure Release Procedure in this
group for procedures. Disconnect the fuel line at the
fuel rail and remove the plastic retainer from the
fuel rail. Take plastic retainer and install it back into
the fuel line from body. Check the O-ring and make
sure that it is in place and not damaged. Attach end
of special test hose tool number 6539 at fuel line con-
nection from the body line. Position opposite end of
this hose tool to an approved gasoline draining sta-
tion. Activate fuel pump and drain tank until empty.
When done remove the special test hose tool number
6539 from the body line. Remove the plastic retainer
from the special test hose tool number 6539 and rein-
stall it into the fuel line from the body. Check the
O-ring and make sure that it is in place and not
damaged. Install the fuel line to the fuel rail.
If electric fuel pump is not operating, tank must be
lowered for fuel draining. Refer to following proce-
dures.
(1) Remove fuel filler cap.
(2) Perform the Fuel System Pressure Release pro-
cedure.
(3) Disconnect negative cable from battery.
(4) Raise vehicle and support.
(5) Certain models are equipped with a separate
grounding wire (strap) connecting the fuel fill tube
assembly to the body. Disconnect wire by removing
screw.
