the engine compartment, on the front extension of
the right front wheel house panel below and behind
the right headlamp. This unit is designed to provide
the audible alert requirements for the ROW premium
VTA.
The alarm siren module consists of microprocessor-
based electronic control circuitry, the siren, and a
nickel metal hydride backup battery. All of the alarm
module components are protected and sealed within
a black molded plastic housing. A stamped steel
mounting bracket is secured to the module with
three stud plates and nuts that fit into slotted holes
at the top and each side of the bracket. The front
surface of the bracket features a tightly grouped
series of small holes that serves as an outlet for the
audible output of the alarm siren. The bottom of the
mounting bracket is bent at a right angle and has an
integral locating tab feature. Two mounting holes in
the horizontal surface of the bracket are used to
secure the alarm siren module to the wheel house
extension with two screws. An integral connector
receptacle extends forward from the upper left corner
of the alarm siren housing, and connects the unit to
the vehicle electrical system through a dedicated
take out and connector of the headlamp and dash
wire harness.
The alarm siren module cannot be repaired or
adjusted and, if faulty or damaged, it must be
replaced.
OPERATION
The microprocessor within the alarm siren module
performs the tasks required to provide the siren unit
features and functions based upon internal program-
ming and electronic arm and disarm message inputs
received from the Intrusion Transceiver Module
(ITM) over a dedicated serial bus communication cir-
cuit. The alarm siren module will self-detect prob-
lems with its internal and external power supply and
communication circuits, then send electronic mes-
sages indicating the problem to the ITM upon receiv-
ing a request from the ITM. The ITM will store a
Diagnostic Trouble Code (DTC) for a detected alarm
siren module fault that can be retrieved with the
DRBIIItscan tool over the Programmable Communi-
cations Interface (PCI) data bus network through the
16-way data link connector located on the driver side
lower edge of the instrument panel.
When the Rest-Of-World (ROW) premium version
of the Vehicle Theft Alarm (VTA) is armed, the alarm
siren module microprocessor continuously monitors
inputs from the ITM for messages to sound its inter-
nal siren and enters its auto-detect mode. While in
the auto-detect mode, if the alarm siren module
detects that its power supply or communication cir-
cuits are being tampered with or have been sabo-taged, it will sound an alarm and continue to operate
through its on-board backup battery. If the arm siren
module is in its disarmed mode when its power sup-
ply or communication circuits are interrupted, the
siren will not sound. The alarm module will also
notify the ITM when the backup battery requires
charging, and the ITM will send a message that will
allow the backup battery to be charged through the
battery current and ground circuits to the alarm
module only when the ignition switch is in the On
position and the engine is running. This will prevent
the charging of the alarm backup battery from
depleting the charge in the main vehicle battery
while the vehicle is not being operated.
The alarm siren module receives battery current
on a fused B(+) circuit through a fuse in the Power
Distribution Center (PDC), and receives ground
through a ground circuit and take out of the head-
lamp and dash wire harness. This ground take out
has a single eyelet terminal connector that is secured
by a ground screw to the left inner fender shield in
the engine compartment. These connections allow the
alarm siren module to remain operational, regardless
of the ignition switch position. The hard wired inputs
and outputs for the alarm siren module may be diag-
nosed and tested using conventional diagnostic tools
and procedures. However, conventional diagnostic
methods will not prove conclusive in the diagnosis of
the internal circuitry or the backup battery of the
alarm siren module, the ITM, the serial bus commu-
nication line, or the electronic message inputs to and
outputs from the alarm siren module. The most reli-
able, efficient, and accurate means to diagnose the
alarm siren module, the ITM, the serial bus commu-
nication line, and the electronic message inputs to
and outputs from the alarm siren module requires
the use of a DRBIIItscan tool. Refer to the appro-
priate diagnostic information.
REMOVAL
(1) Disconnect and isolate the battery negative
cable.
(2) Disconnect the headlamp and dash wire har-
ness connector for the alarm siren module from the
module connector receptacle (Fig. 14).
(3) Remove the two screws that secure the alarm
siren module to the front extension of the right front
wheel house panel.
(4) Remove the alarm siren module from the front
extension of the right front wheel house panel.
INSTALLATION
(1) Position the alarm siren module onto the front
extension of the right front wheel house panel (Fig.
14).

(2) Install and tighten the two screws that secure
the alarm siren module to the front extension of the
right front wheel house panel. Tighten the screws to
6 N´m (50 in. lbs.).
(3) Reconnect the headlamp and dash wire harness
connector for the alarm siren module to the module
connector receptacle.
(4) Reconnect the battery negative cable.
NOTE: If the alarm siren module has been replaced
with a new unit, the new unit MUST be configured
in the Intrusion Transceiver Module (ITM) before the
Vehicle Theft Security System can operate as
designed. The use of a DRBIIITscan tool is required
to configure the alarm siren module settings in the
ITM. Refer to the appropriate diagnostic informa-
tion.
TRANSPONDER KEY
DESCRIPTION
Each ignition key used in the Sentry Key Immobi-
lizer System (SKIS) has an integral transponder chip
(Fig. 15). Ignition keys with this feature can be
readily identified by a gray rubber cap molded onto
the head of the key, while conventional ignition keys
have a black molded rubber cap. The transponderchip is concealed beneath the molded rubber cap,
where it is molded within a plastic mount into the
head of the metal key. In addition to being cut to
match the mechanical coding of the ignition lock cyl-
inder, each new Sentry Key has a unique transpon-
der identification code permanently programmed into
it by the manufacturer. The Sentry Key transponder
cannot be adjusted or repaired. If faulty or damaged,
the entire key must be replaced.
OPERATION
When the ignition switch is turned to the On posi-
tion, the Sentry Key Immobilizer Module (SKIM)
communicates through its antenna with the Sentry
Key transponder using a Radio Frequency (RF) sig-
nal. The SKIM then listens for a RF response from
the transponder through the same antenna. The Sen-
try Key transponder chip is within the range of the
SKIM transceiver antenna ring when it is inserted
into the ignition lock cylinder. The SKIM determines
whether a valid key is present in the ignition lock
cylinder based upon the response from the transpon-
der. If a valid key is detected, that fact is communi-
cated by the SKIM to the Powertrain Control Module
(PCM) over the Programmable Communications
Interface (PCI) data bus, and the PCM allows the
engine to continue running. If the PCM receives an
invalid key message, or receives no message from the
SKIM over the PCI data bus, the engine will be dis-
abled after about two seconds of operation. The Elec-
troMechanical Instrument Cluster (EMIC) will also
respond to the invalid key message on the PCI data
bus by flashing the SKIS indicator on and off.

Each Sentry Key has a unique transponder identi-
fication code permanently programmed into it by the
manufacturer. Likewise, the SKIM has a unique
Secret Key code programmed into it by the manufac-
turer. When a Sentry Key is programmed into the
memory of the SKIM, the SKIM stores the transpon-
der identification code from the Sentry Key, and the
Sentry Key learns the Secret Key code from the
SKIM. Once the Sentry Key learns the Secret Key
code of the SKIM, it is permanently stored in the
memory of the transponder. Therefore, once a Sentry
Key has been programmed to a particular vehicle, it
cannot be used on any other vehicle. (Refer to 8 -ELECTRICAL/VEHICLE THEFT SECURITY -
STANDARD PROCEDURE - TRANSPONDER PRO-
GRAMMING).
The SKIS performs a self-test each time the igni-
tion switch is turned to the On position, and will
store key-related fault information in the form of
Diagnostic Trouble Codes (DTC's) in SKIM memory if
a Sentry Key transponder problem is detected. The
Sentry Key transponder chip can be diagnosed, and
any stored DTC's can be retrieved using a DRBIIIt
scan tool. Refer to the appropriate diagnostic
information.

the cowl plenum to the front washer nozzle fittings
beneath the cowl plenum cover/grille panel.
²Front Wiper Arm- The two front wiper arms
are secured with nuts to the threaded studs on the
ends of the two wiper pivot shafts, which extend
through the cowl plenum cover/grille panel located
near the base of the windshield.
²Front Wiper Blade- The two front wiper
blades are secured to the two front wiper arms with
an integral latch, and are parked on the glass near
the bottom of the windshield when the front wiper
system is not in operation.
²Front Wiper Module- The front wiper pivot
shafts are the only visible components of the front
wiper module. The remainder of the module is con-
cealed within the cowl plenum area beneath the cowl
plenum cover/grille panel. The front wiper module
includes the wiper module bracket, four rubber-iso-
lated wiper module mounts, the front wiper motor,
the wiper motor crank arm, the two wiper drive
links, and the two front wiper pivots.
²Multi-Function Switch- The multi-function
switch is located on the top of the steering column,
just below the steering wheel. The multi-function
switch includes a left (lighting) control stalk and a
right (wiper) control stalk. The right control stalk is
dedicated to providing all of the driver controls for
both the front and rear wiper systems. (Refer to 8 -ELECTRICAL/LAMPS/LIGHTING - EXTERIOR/
MULTI-FUNCTION SWITCH - DESCRIPTION).
²Washer Fluid Level Switch- The washer fluid
level switch is located in a dedicated hole near the
center of the rearward facing surface of the washer
reservoir, behind the right front wheel house splash
shield.
²Washer Pump/Motor- The reversible electric
washer pump/motor unit is located in a dedicated
hole on the lower outboard side of the washer reser-

Hard wired circuitry connects the front wiper and
washer system components to the electrical system of
the vehicle. These hard wired circuits are integral to
several wire harnesses, which are routed throughout
the vehicle and retained by many different methods.
These circuits may be connected to each other, to the
vehicle electrical system and to the front wiper and
washer system components through the use of a com-
bination of soldered splices, splice block connectors,
and many different types of wire harness terminal
connectors and insulators. Refer to the appropriate
wiring information. The wiring information includes
wiring diagrams, proper wire and connector repair
procedures, further details on wire harness routing
and retention, as well as pin-out and location views
for the various wire harness connectors, splices and
grounds.
OPERATING MODES The components of the front
wiper and washer system are designed to work in
concert to provide the following operating modes:
²Continuous Wipe Mode- The control knob on
the right (wiper) control stalk of the multi-function
switch has two continuous wipe positions, Low and
High. When selected, these switch positions will
cause the two-speed front wiper motor to operate in a
continuous low or high speed cycle.
