Alarm Module: Description and Operation Description
DESCRIPTION
An intrusion module (1) is part of the premium version of the Vehicle Theft Alarm (VTA) in the
Vehicle Theft Security System (VTSS). The premium version of the VTA is only available in
vehicles built for certain markets, where the additional features offered by this system are required.
The intrusion module is located in the passenger compartment. This unit is designed to work in
conjunction with the intrusion sensor transmitter and intrusion sensor receiver to provide interior
motion detection and serves as the interface between the Totally Integrated Power Module (TIPM),
the ElectroMechanical Instrument Cluster (EMIC) (also known as the Cab Compartment
Node/CCN) and the alarm siren.
The molded plastic intrusion module housing has two integral mounts (2) that are secured by two
push-in plastic fasteners to the left inner D-pillar just below the belt line. The module is concealed
beneath the quarter inner trim panel. Concealed within the molded plastic housing is the circuitry of
the module, which includes a microprocessor. The module is connected through an integral
connector receptacle (3) to the vehicle electrical system by a take out and connector of the body
wire harness.
The intrusion module unit cannot be adjusted or repaired and, if ineffective or damaged, it must be
replaced.

Alarm Module: Description and Operation Operation
OPERATION
The microprocessor in the intrusion module contains the motion detection logic circuits and controls
all of the features of the premium version of the Vehicle Theft Alarm (VTA). The module uses
On-Board Diagnostics (OBD) and can communicate with other modules in the vehicle as well as
with a diagnostic scan tool using the Controller Area Network (CAN) data bus. This method of
communication is used by the module to communicate with the Totally Integrated Power Module
(TIPM) and for diagnosis and testing through the 16-way data link connector located on the driver
side lower edge of the instrument panel. The intrusion module also communicates with the alarm
siren over a dedicated serial bus circuit.
The intrusion module microprocessor continuously monitors inputs from the intrusion sensor
transmitter and receiver as well as inputs from the TIPM and the alarm siren module. The module
energizes the intrusion sensor transmitter, which transmits ultrasonic signals into the vehicle cabin
through a transmit transducer, then monitors the current draw of the transmitter to detect problems
with the transmitter and transmitter circuits. The module also energizes the intrusion sensor
receiver, which listens to the ultrasonic signals through a receive transducer as they bounce off of
objects in the vehicle interior, then monitors the current draw of the receiver for data signals and to
detect problems with the receiver and receiver circuits. If an object is moving in the interior, a
detection circuit in the module senses this movement through the modulation of the returning data
signals from the receiver.
If movement is detected while the VTA is armed, the intrusion module sends an electronic status
message to the TIPM over the CAN data bus to flash the exterior lighting, and sends an electronic
message to the alarm siren module over a dedicated serial bus line to sound the siren. When the
TIPM detects a breach in the perimeter protection through a door, liftgate or hood ajar switch input,
it flashes the exterior lighting and sends an electronic message to the intrusion module and the
module sends an electronic message to the alarm siren module over a dedicated serial bus line to
sound the siren.
The module also monitors message inputs from the alarm siren module for siren battery or siren
input/output circuit tamper alerts, and for siren battery condition alerts, then sets active and stored
Diagnostic Trouble Codes (DTC) for any monitored system faults it detects. An active fault only
remains for the current ignition switch cycle, while a stored fault causes a DTC to be stored in
memory by the intrusion module. If a fault does not recur for 50 ignition cycles, the module will
automatically erase the stored DTC.
The intrusion module is connected to the vehicle electrical system through the body wire harness.
The module receives battery current through a fuse in the TIPM, and receives ground through the
body wire harness. These connections allow the module to remain operational, regardless of the
ignition switch position.
The hard wired circuits of the intrusion module may be diagnosed using conventional diagnostic
tools and procedures. Refer to the appropriate wiring information. However, conventional
diagnostic methods will not prove conclusive in the diagnosis of the intrusion module or the
electronic controls or communication between modules and other devices that provide some
features of the VTA. The most reliable, efficient, and accurate means to diagnose the intrusion
module or the electronic controls and communication related to intrusion module operation requires
the use of a diagnostic scan tool.

Keyless Entry Module: Description and Operation Description
DESCRIPTION
The Sentry Key REmote Entry Module (SKREEM) (3) (also known as the Sentry Key Immobilizer
Module/SKIM or the Wireless Control Module /WCM) is the primary component of the Sentry Key
Immobilizer System (SKIS). It is also the receiver for the Remote Keyless Entry (RKE) system and
the Tire Pressure Monitor (TPM) system. The SKREEM is located on the right side of the steering
column near the ignition lock cylinder housing and is concealed beneath the column shrouds. The
molded black plastic housing for the SKREEM has an integral molded plastic halo-like antenna ring
(1) that extends from one side. When the SKREEM is properly installed, the antenna ring is
oriented around the circumference of the ignition lock cylinder housing.
A single integral connector receptacle (4) is located adjacent to the antenna ring on the SKREEM
housing. An integral molded plastic mounting tab (2) on the SKREEM housing has a hole in the
center through which a screw passes to secure the unit to the steering column lock housing. The
SKREEM is connected to the vehicle electrical system through a single take out and connector of
the instrument panel wire harness.
The SKREEM cannot be adjusted or repaired. If ineffective or damaged, the entire SKREEM unit
must be replaced.

Keyless Entry Module: Description and Operation Operation
OPERATION
The Sentry Key REmote Entry Module (SKREEM) (also known as the Sentry Key Immobilizer
Module/SKIM or the Wireless Control Module/WCM) contains a Radio Frequency (RF) transceiver
and a microprocessor. The SKREEM transmits RF signals to, and receives RF signals from the
Sentry Key transponder through a tuned antenna enclosed within the molded plastic antenna ring
integral to the SKREEM housing. If this antenna ring is not mounted properly around the ignition
lock cylinder housing, communication problems between the SKREEM and the transponder may
arise. These communication problems will result in Sentry Key transponder-related faults.
The SKREEM also serves as the Remote Keyless Entry (RKE) RF receiver and, if the vehicle is so
equipped, the receiver for the Tire Pressure Monitoring (TPM) system. See: Body and
Frame/Locks/Power Locks/Description and Operation/Description or See: Instrument Panel,
Gauges and Warning Indicators/Tire Monitoring System/Description and Operation/Tire Pressure
Monitoring (TPM) - Description. The SKREEM communicates over the Controller Area Network
(CAN) data bus with the ElectroMechanical Instrument Cluster (EMIC) (also known as the Cab
Compartment Node/CCN), the Powertrain Control Module (PCM), the Totally Integrated Power
Module (TIPM) or the diagnostic scan tool.
The SKREEM and the PCM both use software that includes a rolling code algorithm strategy,
which helps to reduce the possibility of unauthorized Sentry Key Immobilizer System (SKIS)
disarming. The rolling code algorithm ensures security by preventing an override of the SKIS
through the unauthorized substitution of the SKREEM or the PCM. However, the use of this
strategy also means that replacement of either the SKREEM or the PCM units will require a system
initialization procedure to restore system operation.
The SKREEM retains in memory the ID numbers of any Sentry Key transponder that is
programmed into it. A maximum of eight Sentry Key transponders can be programmed into the
SKREEM. For added system security, each SKREEM is programmed with a unique Secret Key
code. This code is stored in memory, sent over the CAN data bus to the PCM, and is encoded to
the transponder of every Sentry Key that is programmed into the SKREEM. Therefore, the Secret
Key code is a common element that is found in every component of the SKIS.
Another security code, called a PIN, is used to gain access to the SKREEM Secured Access Mode.
The Secured Access Mode is required during service to perform the SKIS initialization and Sentry
Key transponder programming procedures. The SKREEM also stores the Vehicle Identification
Number (VIN) in its memory, which it learns through a CAN data bus message from the PCM
during SKIS initialization.
In the event that a SKREEM replacement is required, the Secret Key code can be transferred to
the new SKREEM from the PCM using the diagnostic scan tool and the SKIS initialization
procedure. Proper completion of the SKIS initialization will allow the existing Sentry Keys to be
programmed into the new SKREEM so that new keys will not be required. In the event that the
original Secret Key code cannot be recovered, SKREEM replacement will also require new Sentry
Keys. The diagnostic scan tool will alert the technician during the SKIS initialization procedure if
new Sentry Keys are required.
When the key is inserted into the ignition switch and when the ignition switch is turned to the ON
position, the SKREEM transmits an RF signal to excite the transponder in the ignition key. The
SKREEM then waits for an RF signal response from the transponder. If the response received
identifies the key as valid, the SKREEM sends an electronic valid key message over the CAN data
bus. If the response received identifies the key as invalid or if no response is received from the key
transponder, the SKREEM sends an invalid key message. The PCM will enable or disable engine
operation based upon the status of the SKREEM messages. It is important to note that the default
condition in the PCM is an invalid key ; therefore, if no message is received from the SKREEM by
the PCM, the engine will be disabled and the vehicle immobilized after two seconds of running.
Page 26
The SKREEM also sends electronic security indicator request messages to the EMIC over the CAN
data bus to tell the EMIC how to operate the security indicator. The security indicator request
message from the SKREEM tells the EMIC to turn the indicator ON for about three seconds each
time the ignition switch is turned to the ON position as a bulb test. After completion of the bulb test,
the SKREEM sends security indicator request messages to the EMIC to turn the indicator OFF,
turn the indicator ON, or to flash the indicator ON and OFF. If the security indicator flashes or stays
ON solid after the bulb test, it signifies a SKIS fault. If the SKREEM detects a system malfunction
or the SKIS has become ineffective, the security indicator will stay ON solid. If the SKREEM
detects an invalid key or if a key transponder-related fault exists, the security indicator will flash. If
the vehicle is equipped with the Customer Learn transponder programming feature, the SKREEM
will also send messages to the EMIC to flash the security indicator whenever the Customer Learn
programming mode is being utilized .
The SKIS performs a self-test each time the ignition switch is turned to the ON position, and will
store fault information in the form of a Diagnostic Trouble Code (DTC) in SKREEM memory if a
system malfunction is detected. The hard wired circuits of the SKREEM may be diagnosed using
conventional diagnostic tools and procedures. Refer to the appropriate wiring information.
However, conventional diagnostic methods will not prove conclusive in the diagnosis of the
SKREEM or the electronic controls or communication between other modules and devices that
provide some features of the SKIS. The most reliable, efficient, and accurate means to diagnose
the SKREEM or the electronic controls and communication related to SKREEM operation requires
the use of a diagnostic scan tool.

Parking Assist Control Module: Description and Operation Operation
OPERATION
The microprocessor in the park assist module contains the park assist system logic circuits. The
module uses On-Board Diagnostics (OBD) and can communicate with other electronic modules in
the vehicle as well as with the diagnostic scan tool using the Controller Area Network (CAN) data
bus. This method of communication is also used for park assist system diagnosis and testing
through the 16-way data link connector located on the driver side lower edge of the instrument
panel.
The module provides voltage to the four park assist sensors located behind the rear bumper fascia
and to the park assist display located in the headliner just forward of the liftgate opening header.
The module then monitors return inputs from each of the sensors and the display on dedicated
hard wired data communication circuits. The sensor inputs allow the module to determine when an
obstacle is in the rear path of the vehicle and enables the module to calculate the relative location
of the obstacle, and whether the distance to that obstacle is increasing or decreasing.
Pre-programmed decision algorithms and calibrations allow the module microprocessor to
determine the appropriate park assist system outputs based upon the inputs received from the park
assist sensors and electronic messages received from other modules in the vehicle over the CAN
data bus. When the programmed conditions are met the module sends electronic messages to the
park assist displays over a dedicated serial bus to obtain the proper park assist system visual and
audible outputs. The module also broadcasts electronic messages over the CAN data bus to
enable the other electronic features of the park assist system.
The park assist module microprocessor continuously monitors all of the park assist system
electrical circuits and components to determine the system readiness. If the module detects a
monitored system fault, it sets a Diagnostic Trouble Code (DTC) and sends the appropriate
electronic messages to the ElectroMechanical Instrument Cluster (EMIC) (also known as the Cab
Compartment Node/CCN) over the CAN data bus to control operation of certain park assist system
audible warnings and textual messages displayed in the Electronic Vehicle Information Center
(EVIC) display of the cluster.
The park assist module receives battery current on a fused ignition switch output (run-start) circuit
through a fuse in the Junction Block (JB). The module receives ground through a ground circuit and
take out of the body wire harness. These connections allow the module to be operational whenever
the ignition switch is in the START or ON positions.
The hard wired circuits between components related to the park assist module may be diagnosed
using conventional diagnostic tools and procedures. Refer to the appropriate wiring information.
The wiring information includes wiring diagrams, proper wire and connector repair procedures,
details of wire harness routing and retention, connector pin-out information and location views for
the various wire harness connectors, splices and grounds.
However, conventional diagnostic methods will not prove conclusive in the diagnosis of the park
assist module or the electronic controls or communication between modules and other devices that
provide some features of the park assist system. The most reliable, efficient, and accurate means
to diagnose the park assist module or the electronic controls and communication related to park
assist module operation requires the use of a diagnostic scan tool.

Keyless Entry Module: Description and Operation Description
DESCRIPTION
The Sentry Key REmote Entry Module (SKREEM) (3) (also known as the Sentry Key Immobilizer
Module/SKIM or the Wireless Control Module /WCM) is the primary component of the Sentry Key
Immobilizer System (SKIS). It is also the receiver for the Remote Keyless Entry (RKE) system and
the Tire Pressure Monitor (TPM) system. The SKREEM is located on the right side of the steering
column near the ignition lock cylinder housing and is concealed beneath the column shrouds. The
molded black plastic housing for the SKREEM has an integral molded plastic halo-like antenna ring
(1) that extends from one side. When the SKREEM is properly installed, the antenna ring is
oriented around the circumference of the ignition lock cylinder housing.
A single integral connector receptacle (4) is located adjacent to the antenna ring on the SKREEM
housing. An integral molded plastic mounting tab (2) on the SKREEM housing has a hole in the
center through which a screw passes to secure the unit to the steering column lock housing. The
SKREEM is connected to the vehicle electrical system through a single take out and connector of
the instrument panel wire harness.
The SKREEM cannot be adjusted or repaired. If ineffective or damaged, the entire SKREEM unit
must be replaced.
