repair the open circuit to the fuse in the junction
block as required.
VEHICLE THEFT / SECURITY SYSTEM (VTSS)
SELF - TESTS
A diagnostics test mode is available in the system
to verify operation of all monitored switches or cir-
cuits. To enter diagnostics mode, use a DRB lllt scan
tool and the proper Body Diagnostic Procedure Man-
ual.
The horn will pulse twice to indicate that the deck
lid security switch is present Placing the key in the
ignition will allow the warning lamp, headlamps and
interior lamps to be checked for proper flashing oper-
ation. If any door is open the interior lamps will not
flash. Remove the ignition key from the ignition
switch in order to check for door key cylinder switch
operation. At the completion of each of the following
operations, a horn pulse will occur to indicate proper
operation. Each action must be separated by a mini-
mum of one second or horn pulse will not occur.
• Activate the power door locks in both the lock
and unlock positions.
• Open then close each door one at a time.
• Rotate the ignition key in each of the door lock
cylinders to the lock and unlock positions.
• Cycle the ignition switch key to the ON position
as the last step. A single horn pulse will indicate
proper operation of the ignition switch. This will also
take the system out of the stand alone diagnostic
mode.
The self diagnostic mode may also be exited by
using the DRB lllt scan tool.
Activating the Remote Keyless Entry System
(RKE) to exercise any of the above inputs will also
cause the horn to pulse. When the RKE lock button
is pressed, the RKE module itself will also pulse the
horn. This is part of the RKE normal operation.
SERVICE PROCEDURES
SENTRY KEY IMMOBILIZER SYSTEM
INITIALIZATION
The Sentry Key Immobilizer System (SKIS) initial-
ization should be performed following a SKIM mod-
ule replacement. It can be summarized by the
following:
(1) Obtain the vehicles unique PIN number
assigned to it’s original SKIM module from the vehi-
cle owner, the vehicle’s invoice or from Chrysler’s
Customer Center.
(2) With the DRB lllt scan tool, select “Theft
Alarm,” “SKIM,” Miscellaneous.” Select “SKIM Mod-
ule Replaced” function and the DRB lllt will prompt
you through the following steps.
(3) Enter secured access mode using the unique
four digit PIN number.
(4) Program the vehicle’s VIN number into the
SKIM’s memory.
(5) Program the country code into the SKIM’s
memory (U.S.).
(6) Transfer the vehicle’s unique Secret Key data
from the PCM. This process will require the SKIM
module to be in secured access mode. The PIN
number must be entered into the DRB lllt before the
SKIM will enter secured access mode. Once
secured access mode is active, the SKIM will
remain in that mode for 60 seconds.
(7) Program all customer keys into the SKIM’s
memory. This required that the SKIM be in secured
access mode The SKIM module will immediately
exit secured access mode after each key is pro-
grammed.
NOTE: SECURED ACCESS MODE is not required to
query the programmed status of the key.
NOTE: If a PCM is replaced, the unique “Secret
Key” data must be transferred from the SKIM mod-
ule to the PCM. This procedure requires the SKIM
to be placed in SECURED ACCESS MODE using the
four digit PIN code.

TRANSPONDER PROGRAMMING
Three programmed Sentry Key transponders are
included with the Sentry Key Immobilizer System
(SKIS) when it is shipped from the factory. The Sen-
try Key Immobilizer Module (SKIM) can be pro-
grammed to recognize up to five additional
transponders, for a total of eight Sentry Keys. The
following “Customer Learn” programming procedure
for the programming of additional transponders
