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 Front Control Module (FCM), the
ElectroMechanical Instrument Cluster (EMIC) (also known as the Cab Compartment Node/CCN)
and the alarm siren.

The intrusion module housing has two integral mounts (2) that secure the module, and an integral
connector receptacle (3). Concealed within the molded plastic housing is the circuitry of the
module, which includes a microprocessor.

The intrusion module (2) is secured within a cavity on the right side of a molded plastic
intermediate step assembly (1) located on the rear floor panel under the second row seat cushion
by two slots and two latch features integral to the floor of the step cavity The module is concealed
beneath a carpeted trim cover secured by hook and loop fasteners over the step cavity. The
inboard side of this step cavity also contains the satellite radio receiver (4) on vehicles that are so
equipped. The module is connected to the vehicle electrical system by a take out and connector of
the body wire harness (3).

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 Front Control Module (FCM) and
the ElectroMechanical Instrument Cluster (EMIC) (also known as the Cab Compartment
Node/CCN). The 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 EMIC 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, the intrusion module sends an electronic message to the FCM over the
CAN data bus to flash the exterior lighting and sends another message to the alarm siren module
over the dedicated serial bus line to sound the siren. When the EMIC or FCM detect a breach in
the perimeter protection through a door, liftgate, flip-up glass, or hood ajar switch input, they send
an electronic message to the intrusion module and the module sends a message to the FCM to
flash the exterior lighting and a message to the alarm siren module 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 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
module. If a fault does not recur for 50 ignition cycles, the module will automatically erase the
stored DTC.

The intrusion module receives battery voltage on a fused B(+) circuit through a fuse in the Junction
Block (JB), and is grounded at all times through a hard wired remote ground point. 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. Refer to the appropriate diagnostic information.

Ignition Shut Down Relay (For Antitheft): Description and Operation Operation
PCM Output
PCM OUTPUT
The ASD relay supplies battery voltage (12+ volts) to the fuel injectors and ignition coil(s). With

certain emissions packages it also supplies 12-volts to the oxygen sensor heating elements.
The ground circuit for the coil within the ASD relay is controlled by the Powertrain Control Module

(PCM). The PCM operates the ASD relay by switching its ground circuit on and off.
The ASD relay will be shut-down, meaning the 12-volt power supply to the ASD relay will be

de-activated by the PCM if:

- The ignition key is left in the ON position. This is if the engine has not been running for
approximately 1.8 seconds.

- There is a crankshaft position sensor signal to the PCM that is lower than pre-determined values.
ASD Sense - PCM Input
ASD SENSE - PCM INPUT
A 12 volt signal at this input indicates to the PCM that the ASD has been activated. The relay is

used to connect the oxygen sensor heater element, ignition coil and fuel injectors to 12 volt +
power supply.

This input is used only to sense that the ASD relay is energized. If the Powertrain Control Module
(PCM) does not see 12 volts at this input when the ASD should be activated, it will set a Diagnostic
Trouble Code (DTC).

Keyless Entry Module: Description and Operation Description
DESCRIPTION
The functions and features of the Sentry Key Immobilizer Module (SKIM) (also known as the Sentry

Key REmote Entry Module/SKREEM or the Wireless Control Module/WCM) are all integral to the
Wireless Ignition Node (WIN) (1) in this vehicle. The WIN is the primary component of the Sentry
Key Immobilizer System (SKIS). It includes the integral ignition switch and is also the receiver for
the Remote Keyless Entry (RKE) system and the Tire Pressure Monitor (TPM) system. The WIN is
located in the instrument panel, just to the right of the steering column. The remainder of the WIN
including its mounting provisions and electrical connections are concealed within the instrument
panel.

The WIN cannot be adjusted or repaired, but is flash update capable. If ineffective or damaged the
entire WIN must be replaced. See: Accessories and Optional Equipment/Antitheft and Alarm

Keyless Entry Module: Description and Operation Operation
OPERATION
The functions and features of the Sentry Key Immobilizer Module (SKIM) (also known as the Sentry

Key REmote Entry Module/SKREEM or the Wireless Control Module/WCM) are all integral to the
Wireless Ignition Node (WIN) in this vehicle. The WIN contains a Radio Frequency (RF) transceiver
and a microprocessor. The WIN transmits Low Frequency (LF) signals to, and receives LF signals
from the Sentry Key transponder integral to the FOB with Integrated Key (FOBIK) through a tuned
antenna internal to the WIN housing.

The WIN 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 WIN 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) or the diagnostic scan tool.

The WIN 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 WIN or the PCM. However, the use of this strategy also means that
replacement of either the WIN or the PCM units will require a system initialization procedure to
restore system operation.

The WIN retains in memory the ID numbers of any Sentry Key FOBIK transponder that is
programmed into it. A maximum of eight Sentry Key FOBIK transponders can be programmed into
the WIN. For added system security, each WIN 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 FOBIK that is programmed into the WIN. 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 WIN Secured Access Mode. The
Secured Access Mode is required during service to perform the SKIS initialization and Sentry Key
FOBIK transponder programming procedures. The WIN 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 WIN replacement is required, the Secret Key code can be transferred to the new
WIN from the PCM using the diagnostic scan tool and the SKIS initialization procedure. Proper
completion of the SKIS initialization will allow the existing Sentry Key FOBIKs to be programmed
into the new WIN so that new FOBIKs will not be required. In the event that the original Secret Key
code cannot be recovered, WIN replacement will also require new Sentry Key FOBIKs. The
diagnostic scan tool will alert the technician during the SKIS initialization procedure if new Sentry
Key FOBIKs are required.

When the ignition switch is turned to the ON position, the WIN transmits a LF signal to excite the
transponder in the FOBIK. The WIN then waits for a LF signal response from the transponder. If
the response received identifies the FOBIK as valid, the WIN sends an electronic valid key
message to the PCM over the CAN data bus. If the response received identifies the FOBIK as
invalid or if no response is received from the FOBIK transponder, the WIN sends an invalid key
message to the PCM. The PCM will enable or disable engine operation based upon the status of
the WIN 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 WIN by the PCM, the engine will be disabled and the
vehicle immobilized after two seconds of running.

The WIN 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 WIN 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 WIN 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 WIN detects a system malfunction or the SKIS has become
ineffective, the security indicator will stay ON solid. If the WIN detects an invalid FOBIK or if a
FOBIK transponder-related fault exists, the security indicator will flash. If the vehicle is equipped
with the Customer Learn transponder programming feature, the WIN 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 WIN memory if a system
malfunction is detected. The hard wired circuits of the WIN 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 WIN 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 WIN or the
electronic controls and communication related to WIN operation requires the use of a diagnostic
scan tool. Refer to the appropriate diagnostic information.

Parking Assist Control Module: Description and Operation Description

DESCRIPTION
The Park Assist Module (5) is secured within a cavity on the left side of a molded plastic

intermediate step assembly (4) located on the rear floor panel (3) under the second row seat
cushion. The module is concealed beneath a carpeted trim cover secured by hook and loop
fasteners over the step cavity. The inboard side of this cavity also contains the Final Drive Control
Module (FDCM) (1) on vehicles that are so equipped. Both modules are connected to the vehicle
electrical system through dedicated take outs and connectors of the underbody wire harness (2).

Concealed within the molded plastic park assist module housing (1) is a microprocessor and the
other electronic circuitry of the module. The module housing is sealed to enclose and protect the
internal electronic circuitry. The module software is flash programmable.

There are four mounting tabs (2 and 3) integral to the module housing that secure the module
through two slots and two latch features integral to the floor of the step cavity. Two connector
receptacles (4) containing terminal pins that connect the module to the vehicle electrical system are
integral to the one side of the housing. One of the receptacles is utilized in vehicles equipped with
only the rear park assist system, while both receptacles are used on vehicles equipped with both
the front and rear park assist systems.

The park assist module cannot be adjusted or repaired and, if damaged or ineffective, it must be
replaced.

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 each of the park assist sensors located behind the front and rear
bumper fascias and to the front and rear park assist displays. The module then monitors return
inputs from each of the sensors and the displays on dedicated hard wired data communication
circuits. The sensor inputs allow the module to determine when an obstacle is in the front or 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 instrument cluster over the CAN data bus to control operation of certain
park assist system audible warnings and textual messages displayed in the reconfigurable display
of the instrument 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 underbody 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. Refer to the appropriate
diagnostic information.
