Refer to Wiring Diagrams for complete circuit dia-
grams. Following are general descriptions and opera-
tions for the major components in the power seat
system and memory seat system.
DESCRIPTION - MEMORY SYSTEM
An electronic memory system is available on some
models. The memory system is able to store and
recall the driver side power seat positions (including
the power recliner position) and both outside side
view mirrors positions for two drivers. On vehicles
equipped with a factory radio, the memory system is
also able to store and recall radio station presets fortwo drivers. The memory system also will store and
recall the last station listened to for each driver, even
if it is not one of the preset stations.
The memory system will automatically return to
its preset settings when the corresponding numbered
button of the memory switch is depressed, or when
the doors are unlocked using the corresponding
Remote Keyless Entry (RKE) transmitter. A customer
programmable feature of the memory system allows
the RKE recall of memory features to be disabled, if
desired. This programmable feature is internal in the
EVIC module, which is located in the overhead con-
sole.
A Memory Seat Mirror Module (MSMM) is used on
some models to control and integrate the many elec-
tronic functions and features included in the memory
seat and mirror systems.
The memory system includes the following compo-
nents:
²Memory Seat Mirror Module (MSMM)
²Memory set switch
²Position potentiometers on both outside side
view mirrors
²Position potentiometers on the driver side power
seat track and power seat recliner motors.
²Electronic Vehicle Information Center (EVIC)
²Radio receiver (if PCI data bus capable).
Certain functions of the memory system rely upon
resources shared with other electronic modules in the
vehicle over the Programmable Communications
Interface (PCI) J1850 data bus network. The PCI
data bus network allows the sharing of sensor infor-
mation. This helps to reduce wire harness complexity,
internal controller hardware, and component sensor
current loads. At the same time, this system provides
increased reliability, enhanced diagnostics, and
allows the addition of many new feature capabilities.
Initial diagnosis of these electronic modules or the
PCI data bus network requires the use of a DRBIIIt
scan tool and the proper Diagnostic Procedures man-
ual. If this method does not prove conclusive, the use
of a automotive meter such as the Fluket, the proper
wiring schematics and the service manual diagnostic
routines are required.
The other electronic modules that may affect mem-
ory system operation are as follows:
²Body Control Module (BCM)- Refer toBody
Control Modulein Electronic Control Modules for
more information.
²Powertrain Control Module (PCM)- Refer to
Powertrain Control Modulein Electronic Control
Modules for more information.
²Transmission Control Module (TCM)- Refer
toTransmission Control Modulein Electronic
Control Modules for more information.

diagrams. Following are descriptions, theory of oper-
ation, diagnosis/testing procedures and removal/in-
stallation procedures of the major components in the
memory and power seat systems.
OPERATION
OPERATION - POWER SEAT SYSTEM
The power seat system receives battery current
through fuse #22 in the Intelligent Power Module
and a circuit breaker under the front seats, regard-
less of the ignition switch position.
When a power seat switch control knob or knobs
are actuated, a battery feed and a ground path are
applied through the switch contacts to the appropri-
ate power seat track adjuster motor. The selected
adjuster motor operates to move the seat track
through its drive unit in the selected direction until
the switch is released, or until the travel limit of the
seat track is reached. When the switch is moved in
the opposite direction, the battery feed and ground
path to the motor are reversed through the switch
contacts. This causes the adjuster motor to run in the
opposite direction.
No power seat switch should be held applied in any
direction after the seat track has reached its travel
limit. The power seat track each contain a self-reset-
ting circuit breaker to protect them from overload.
However, consecutive or frequent resetting of the cir-
cuit breaker must not be allowed to continue, or the
motor may be damaged. Refer to the owner's manual
in the vehicle glove box for more information on the
features, use and operation of the power seat system.
OPERATION - MEMORY SYSTEM
The Memory Seat Mirror Module (MSMM) receives
battery current through fuse #22 in the Intelligent
Power Module and the power seat system circuit
breaker, located under the driver side front seat near
the rear edge of the seat cushion pan. The memory
system does not operate with the Ignition-Off Draw
(IOD) fuse removed. The MSMM will drive a maxi-
mum of 2 motors at a time in a given direction. If
conflicting directions are requested, the priority for
response will be approximately as follows:
²Seat Track Rearward or Forward
²Seat Front Down or Up
²Seat Rear Down or Up
²Recliner Rearward or ForwardThe inputs from these switches to the MSMM is a
current limited battery source fed by the MSMM.
This protects the MSMM printed circuit board traces
from acting as fuses. All of these switch contact
inputs to the MSMM are normally closed to ground,
except when actuated.
See the owner's manual in the vehicle glove box for
more information on the features, use and operation
of the memory system. For diagnosis of the MSMM,
the PCI data bus, or the other electronic modules on
the PCI data bus that provide inputs and outputs for
the memory system, the use of a DRBIIItscan tool
and the proper Diagnostic Procedures manual are
recommended.
ELECTRONIC VEHICLE INFORMATION CENTER
The Electronic Vehicle Information Center (EVIC)
serves as the user interface for the memory system.
It displays memory system status messages and pro-
vides the user with the means for enabling and dis-
abling the many customer programmable features
available on the vehicle, including those for the mem-
ory system.
See the owner's manual in the vehicle glove box for
more information on the features, use and operation
of the EVIC. Refer toElectronic Vehicle Informa-
tion Centerin Overhead Console Systems for more
information on the EVIC.
DIAGNOSIS AND TESTING
DIAGNOSIS AND TESTING - POWER SEAT
SYSTEM
Following are tests that will help to diagnose the
hard wired components and circuits of the power seat
system. However, if the vehicle is also equipped with
the optional memory system, these tests may not
prove conclusive in the diagnosis of the driver side
power seat. In order to obtain conclusive testing of
the driver side power seat with the memory system
option, the Programmable Communications Interface
(PCI) data bus network and all of the electronic mod-
ules that provide inputs to, or receive outputs from
the memory system components must be checked.
The most reliable, efficient, and accurate means to
diagnose the driver side power seat with the memory
system option requires the use of a DRBIIItscan tool
and the proper Diagnostic Procedures manual. The
DRBIIItscan tool can provide confirmation that the
PCI data bus is functional, that all of the electronic
modules are sending and receiving the proper mes-
sages on the PCI data bus, and that the memory sys-
tem is receiving the proper hard wired inputs and
relaying the proper hard wired outputs to perform its
driver side power seat functions.

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 SKIS)
SENTRY KEY IMMOBILIZER SYSTEM
The Sentry Key Immobilizer System (SKIS) is
available as a factory-installed option on this vehicle.
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 components of
the system are the Sentry Key Immobilizer Module
(SKIM), Sentry Key (ignition key with a transponder
molded into the head), indicator light, Body Control
Module (BCM), and the Powertrain Control Module
(PCM). The SKIM 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 SKIM 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 SKIM 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 transmitter.
²Door Cylinder Lock Switches.
For vehicles equipped with SKIS, 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. If fault is
detected on the driver key cylinder input, the indica-
tor 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 ignition key/
RSVEHICLE THEFT SECURITY8Q-1

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.
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.
(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 (excluding liftgate).
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 SKIS 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 IMMOBILIZER SYSTEM
The SKIS includes keys from the factory which are
pre-programmed. Each SKIM will recognize a maxi-
mum 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 programmed
to the SKIM on the vehicle in order for the system to
recognize them as valid keys. This can be done by
the dealer with a DRB IIItscan tool or by a cus-
tomer 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 SKIS 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.
The SKIS can be diagnosed and any stored DTC's
can be retrieved using a DRB IIItscan tool as
