GENERAL INFORMATION
INTRODUCTION
The Smart Key Immobilizer System (SKIS) is
available factory-installed optional equipment for this
model. Following are some general descriptions of the
features and components of the SKIS. Refer to the
vehicle owner's manual for more information on the
use and operation of the SKIS. Refer to 8W-30 - Fuel/
Ignition System in Group 8W - Wiring Diagrams for
complete circuit descriptions and diagrams.
SMART KEY IMMOBILIZER SYSTEM
The Smart Key Immobilizer System (SKIS) is
designed to provide passive protection against unau-
thorized vehicle use by preventing the engine from
operating while the system is armed. The primary
components of this system are the Smart Key Immo-
bilizer Module (SKIM), the Smart Key transponder,
the SKIS indicator lamp, and the Powertrain Control
Module (PCM), for gasoline engines, and the Body
Control Module (BCM) for diesel engines.
The SKIM is installed on the steering column near
the ignition lock cylinder. The transponder is located
under the molded rubber cap on the head of the igni-
tion key. The SKIS indicator lamp is located in the
instrument cluster.
The SKIS includes two valid Smart Key transpon-
ders from the factory. If the customer wishes, addi-
tional non-coded blank Smart Keys are available.
These blank keys can be cut to match a valid ignition
key, but the engine will not start unless the key tran-
sponder is also programmed to the vehicle. The SKIS
will recognize no more than eight valid Smart Key
transponders at any one time.
The SKIS performs a self-test each time the igni-
tion switch is turned to the On position, and will
store Diagnostic Trouble Codes (DTCs) if a systemmalfunction is detected. The SKIS can be diagnosed,
and any stored DTC can be retrieved using a DRB
scan tool as described in the proper Diagnostic Pro-
cedures manual.
DESCRIPTION AND OPERATION
SMART KEY IMMOBILIZER MODULE
The Smart Key Immobilizer Module (SKIM) con-
tains a Radio Frequency (RF) transceiver and a cen-
tral processing unit, which includes the Smart Key
Immobilizer System (SKIS) program logic. The SKIS
programming enables the SKIM to program and
retain in memory the codes of at least two, but no
more than eight electronically coded Smart Key tran-
sponders. The SKIS programming also enables the
SKIM to communicate over the Chrysler Collision
Detection (CCD) data bus network with the Power-
train Control Module (PCM), the instrument cluster
and/or the DRB scan tool.
The SKIM transmits and receives RF signals
through a tuned antenna enclosed within a molded
plastic ring formation that is integral to the SKIM
housing. When the SKIM is properly installed on the
steering column, the antenna ring is oriented around
the circumference of the ignition lock cylinder hous-
ing. This antenna ring must be located within eight
millimeters (0.31 inches) of the Smart Key in order
to ensure proper RF communication between the
SKIM and the Smart Key transponder.
For added system security, each SKIM is pro-
grammed with a unique ªSecret Keyº code and a
security code. The SKIM keeps the ªSecret Keyº code
in memory and sends the code over the CCD data
bus to the PCM, which also keeps this code in its
memory. The SKIM also sends the ªSecret Keyº code
to each of the programmed Smart Key transponders.
The security code is used by the assembly plant to
NS/GSVEHICLE THEFT/SECURITY SYSTEMS 8Q - 1

determine whether a valid key is in the ignition lock
cylinder.
The Smart Key transponder cannot be repaired
and, if faulty or damaged, it must be replaced.
SMART KEY IMMOBILIZER SYSTEM INDICATOR
LAMP
The Smart Key Immobilizer System (SKIS) indica-
tor lamp gives an indication when the SKIS is faulty
or when the vehicle has been immobilized due to the
use of an invalid ignition key. The lamp is controlled
by the instrument cluster circuitry based upon mes-
sages received from the Smart Key Immobilizer Mod-
ule (SKIM) on the Chrysler Collision Detection (CCD)
data bus.
The SKIM sends messages to the instrument clus-
ter to turn the lamp on for about three seconds when
the ignition switch is turned to the On position as a
bulb test. After completion of the bulb test, the SKIM
sends bus messages to keep the lamp off for a dura-
tion of about one second. Then the SKIM sends mes-
sages to the instrument cluster circuitry to turn the
lamp on or off based upon the results of the SKIS
self-tests. If the SKIS indicator lamp comes on and
stays on after the bulb test, it indicates that the
SKIM has detected a system malfunction and/or that
the SKIS has become inoperative. If the SKIM
detects an invalid key when the ignition switch is
turned to the On position, it sends messages to the
instrument cluster to flash the SKIS indicator lamp.
The SKIM can also send messages to the instru-
ment cluster to flash the lamp and to generate a sin-
gle audible chime tone. These functions serve as an
indication to the customer that the SKIS has been
placed in its ªCustomer Learnº programming mode.
See Smart Key Immobilizer System Transponder Pro-
gramming in this group for more information on the
ªCustomer Learnº programming mode.
The SKIS indicator lamp uses a replaceable incan-
descent bulb and bulb holder on the instrument clus-
ter electronic circuit board. Refer to Group 8E -
Instrument Panel Systems for diagnosis and service
of a faulty SKIS indicator lamp. If the SKIS indicator
lamp comes on and stays on after the bulb test func-
tion, diagnosis of the SKIS should be performed with
a DRB scan tool and the proper Diagnostic Proce-
dures manual.
