TRANSPONDER KEY
DESCRIPTION
The Sentry Key Remote Entry System (SKREES)
uses a transponder chip that is integral to each igni-
tion key to communicate with the Sentry Key Remote
Entry Module (SKREEM). Ignition keys are supplied
with the vehicle when it is shipped from the factory.
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, TransponderKey, 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
code will be required to complete this task since you
will need it to enter the Secured Access Mode in the
SKREEM. The following steps must be completed
using a DRBIIItscan tool:
(1) Insert the blank key into the ignition and turn
it to the RUN position.
(2) Using a DRBIIItscan tool, select9Theft
Alarm,99SKREEM,99Miscellaneous,9and then9Pro-
gram New Key.9
(3) Enter the four digit PIN code using the
DRBIIItscan tool. When programming is completed,
the SKREEM will exit Secured Access Mode and the
DRBIIItscan tool will display the results of your
attempt to program the key. One of five distinct
results may be displayed. All five are listed below:
²(Programming Successful(is displayed if the
Sentry Key programming is successful.
8Q - 6 VEHICLE THEFT SECURITYRS
SENTRY KEY REMOTE ENTRY MODULE (Continued)

²(Learned Key in Ignition(is displayed if the
key in the ignition has already been programmed
into that vehicle's SKREEM.
²(Eight Keys Already Learned (At The Maxi-
mum) Programming Not Done(is displayed if
eight keys have already been programmed into the
SKREEM. In this case, if a new key needs to be
added due to a lost or defective key, the9Erase All
Keys9command (which requires entering the Secured
Access Mode) has to be performed. Following the
9Erase All Keys9command, all keys that will be used
to operate the vehicleMUSTbe reprogrammed to
the SKREEM.
²(Programming Not Attempted(is displayed
after an9Erase All Keys9function is executed.
²(Programming Key Failed(is displayed if fur-
ther diagnosis is required.
To learn additional keys, turn the ignition OFF,
remove the learned key, insert the next new blank
key, and repeat the steps from the beginning.
ªCUSTOMER LEARNº MODE
This feature is only available on domestic vehicles
or those which have a U.S. country code designator.
This procedure requires access to at least two valid
Sentry Keys. If two valid Sentry Keys are not avail-
able, Sentry Key programming will require the use of
a DRBIIItscan tool.
The steps required to program Sentry Keys with
two valid Sentry Keys follows:
(1) Obtain the blank Sentry Key(s) that need to be
programmed. Cut the keys to match the ignition lock
cylinder mechanical key codes.
(2) Insert one of the two valid Sentry Keys into the
ignition switch and turn the ignition switch to the
ON position.
(3) After the ignition switch has been in the ON
position for longer than three seconds, but no more
than fifteen seconds, cycle the ignition switch back to
the OFF position. Replace the first valid Sentry Key
in the ignition lock cylinder with the second valid
Sentry Key and turn the ignition switch back to the
ON position. The second valid Sentry Key must be
inserted within 15 seconds of removing the first valid
Sentry key.
(4) About ten seconds after the completion of Step
3, the indicator light will start to flash and a single
audible chime tone will sound to indicate that the
system has entered the9Customer Learn9program-
ming mode.
(5) Within sixty seconds of entering the9Customer
Learn9programming mode, turn the ignition switch
to the OFF position, replace the valid Sentry Key
with a blank Sentry Key transponder, and turn the
ignition switch back to the ON position.(6) About ten seconds after the completion of Step
5, a single audible chime tone will sound and the
indicator light will stop flashing and stay on solid for
three seconds and then turn off to indicate that the
blank Sentry Key has been successfully programmed.
The SKREES will immediately exit the9Customer
Learn9programming mode and the vehicle may be
started using the newly programmed Sentry Key.
NOTE: The Remote Keyless Entry (RKE) Transmitter
will also be programmed during this procedure.
These steps must be completed in their entirety for
each additional Sentry Key to be programmed. If any
of the above steps are not completed in the given
sequence, or within the allotted time, the SKREES
will exit the9Customer Learn9programming mode
and the programming will be unsuccessful. The
SKREES will also automatically exit the9Customer
Learn9programming mode if:
²It sees a non-blank Sentry Key when it should
see a blank.
²If it has already programmed four (4) valid Sen-
try Keys.
²If the ignition switch is turned to the OFF posi-
tion for more than about fifty (50) seconds.
NOTE: If you attempt to start the vehicle while in
ªCustomer Learnº mode (LED flashing), the vehicle
will behave as though an invalid key is being used
(i.e. the engine will stall after two (2) seconds of
running). No faults will be logged.
NOTE: Once a Sentry Key has been programmed to
a particular vehicle, it cannot be used on any other
vehicle.
VTSS/SKIS INDICATOR LAMP
DESCRIPTION
The Sentry Key Remote Entry System (SKREES)
uses an indicator light to convey information on the
status of the system to the customer. This light is
shared with the Vehicle Theft Security System
(VTSS). The light is located in the Mechanical
Instrument Cluster (MIC). The VTSS status is con-
trolled by the Body Control Module (BCM), via Pro-
grammable Communication Interface (PCI) data bus
communication with the MIC, based upon messages
it receives from the Sentry Key Remote Entry Mod-
ule (SKREEM) on the PCI data bus.
RSVEHICLE THEFT SECURITY8Q-7
TRANSPONDER KEY (Continued)

OPERATION
The Mechanical Instrument Cluster (MIC) per-
forms a four second bulb check via PCI communica-
tion with the Sentry Key Remote Entry Module
(SKREEM). After the bulb check, the lamp is con-
trolled according to SKREEM messages. Then, the
SKREEM sends messages to the BCM to operate the
light based upon the results of the Sentry Key
Remote Entry System (SKREES) self tests. The light
may be actuated in two possible ways, flashing or on
solid. If the light comes on and stays on solid after a
power-up test, this indicates that the SKREEM has
detected a system malfunction. If the SKREEM
detects an invalid key when the ignition switch is
moved to the ON position, it sends a message on thePCI bus to the MIC, to flash the light. The SKREEM
can also send a message to flash the light and gen-
erate a single audible chime at the same time. These
two events occurring simultaneously indicate that
the SKIS has been placed into the9Customer Learn9
mode (Refer to 8 - ELECTRICAL/VEHICLE THEFT
SECURITY/TRANSPONDER KEY - STANDARD
PROCEDURE). If the light comes on and stays on
after the power-up test, diagnosis of the SKREES
should be performed using a DRBIIItscan tool and
the appropriate Body Diagnostic Procedures informa-
tion. The light is a Light Emitting Diode (LED) and
is not a serviceable component.

INTEGRATED POWER MODULE
DESCRIPTION
The Integrated Power Module (IPM) is a combina-
tion of the Power Distribution Center (PDC) and the
Front Control Module (FCM). The IPM is located in
the engine compartment, next to the battery on this
model (Fig. 1). The power distribution center mates
directly with the Front Control Module (FCM) to
form the IPM Fuse and Relay Center. The power dis-
tribution center (PDC) is a printed circuit board
based module that contains fuses and relays, while
the front control module contains the electronics con-
trolling the IPM and other functions. This IPM con-
nects directly to the battery positive via a four pin
connector. The ground connection is via two other
connectors. The IPM provides the primary means of
voltage distribution and protection for the entire
vehicle.
The molded plastic IPM housing includes a base
and cover. The IPM cover is easily opened or removed
for service access by squeezing the two marked cover
latches and has a fuse and relay layout map integral
to the inside surface of the cover. This IPM housing
base and cover are secured in place by an IPM
mounting bracket. This mounting bracket is designed
to allow the IPM to rotate counter-clockwise once the
locking tab is disengaged. The IPM mounting bracketis secured in place by bolts threaded into the left
front wheel house.
OPERATION
All of the current from the battery and the gener-
ator output enters the Integrated Power Module
(IPM) via a four- pin connector on the bottom of the
module. The IPM cover is unlatched and opened or
removed to access the fuses or relays. Internal con-
nections of all of the power distribution center cir-
cuits is accomplished by a combination of bus bars
and a printed circuit board. Refer to the Wiring sec-
tion of the service manual for complete IPM circuit
schematics.
REMOVAL
