mer circuit.
²Vanity Lamps- Available single intensity van-
ity lamps are located on each side of a covered mirror
on both the right and left sun visors, and are con-
trolled by an integral vanity mirror cover-actuated
switch on the courtesy lamp circuit.
Other components of the interior lighting system
for this model include:
²Body Control Module- The Body Control
Module (BCM) is located on the Junction Block (JB)
under the driver side outboard end of the instrument
panel. (Refer to 8 - ELECTRICAL/ELECTRONIC
CONTROL MODULES/BODY CONTROL MODULE
- DESCRIPTION).
²Door Ajar Switches- A door ajar switch is
integral to the door latch mechanism of each front
and rear door.
²Flip-Up Glass Ajar Switch- A flip-up glass
ajar switch is integral to the flip-up glass latch mech-
anism on the top of the tailgate inner panel.
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 left control stalk is
dedicated to providing almost all of the driver con-
trols for both the exterior and interior lighting sys-
tems. (Refer to 8 - ELECTRICAL/LAMPS/LIGHTING
- EXTERIOR/MULTI-FUNCTION SWITCH -
DESCRIPTION).
²Tailgate Ajar Switch- A tailgate ajar switch is
integral to the latch mechanism of the tailgate.
Hard wired circuitry connects the interior lighting
system components to the electrical system of the
vehicle. These hard wired circuits are integral to sev-
eral 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 interior lighting
system components through the use of a combination
of soldered splices, splice block connectors, and many
different types of wire harness terminal connectors
and insulators. Refer to the appropriate wiring infor-
mation. The wiring information includes wiring dia-
grams, proper wire and connector repair procedures,
further details on wire harness routing and reten-
tion, as well as pin-out and location views for the
various wire harness connectors, splices and grounds.
OPERATION
The interior lighting systems can be divided into
two general classifications based upon the circuit
that controls their operation: The courtesy lamp cir-cuit, or the panel lamps dimmer circuit. Following
are paragraphs that briefly describe the operation of
each of the major interior lighting systems. The hard
wired circuits and components of the interior lighting
systems may be diagnosed and tested using conven-
tional diagnostic tools and procedures. However, con-
ventional diagnostic methods may not prove
conclusive in the diagnosis of the Body Control Mod-
ule (BCM), the ElectroMechanical Instrument Clus-
ter (EMIC), or the Programmable Communications
Interface (PCI) data bus network. The most reliable,
efficient, and accurate means to diagnose the BCM,
the EMIC, and the PCI data bus network inputs and
outputs related to the various interior lighting sys-
tems requires the use of a DRBIIItscan tool. Refer
to the appropriate diagnostic information.
COURTESY LAMP CIRCUIT Depending upon the
selected vehicle options the courtesy lamp circuit
may include the courtesy lamps located below the
instrument panel, the dome or map/reading lamps
located in the headliner near the windshield, the
cargo lamp located in the headliner near the rear
roof header, and the vanity lamps located in the sun
visors. The lamps in the courtesy lamp circuit are
provided with battery current at all times from a
fused B(+) fuse in the Junction Block (JB) through a
fused B(+) circuit. The Body Control Module (BCM)
controls the ground path for these lamps using an
internal driver through the courtesy lamp driver cir-
cuit based upon hard wired inputs from the door ajar
switches, the flip-up glass ajar switch, and the tail-
gate ajar switch. After all of the ajar switch inputs to
the BCM transition to open, the BCM will keep the
lamps illuminated for about 27 seconds, then fade
the lamps to off (theater dimming) over about three
seconds.
The BCM also provides courtesy lamp operation
based upon a resistor multiplexed input from the
interior lighting control ring on the left (lighting)
control stalk of the multi-function switch through the
headlamp switch mux circuit, and in response to cer-
tain inputs from the optional Remote Keyless Entry
(RKE) system. A resistor multiplexed courtesy lamp
defeat input from the control ring on the left (light-
ing) control stalk of the multi-function switch will
cause the BCM to override normal courtesy lamp
operation based upon inputs from all of the ajar
switches. A hard wired input from the courtesy lamp
defeat switch in the optional cargo lamp through a
rear courtesy lamp control circuit will cause the BCM
to override normal courtesy lamp operation based
upon inputs from only the flip-up glass and tailgate
ajar switches.
For those lamps on the courtesy lamp circuit with
independent switching, such as the optional reading
lamps and vanity lamps, the BCM provides a ground

DOOR AJAR SWITCH
DESCRIPTION
This vehicle has four door ajar switches, one for
each door. Each switch is concealed within and inte-
gral to its respective door latch unit. The switches
are momentary leaf contact-type units that are actu-
ated by the door latch mechanisms. A short pigtail
wire and connector on each door latch connects the
door ajar switch to the vehicle electrical system
through its respective door wire harness. The door
ajar switches cannot be adjusted or repaired and, if
faulty or damaged, the door latch unit must be
replaced. (Refer to 23 - BODY/DOOR - FRONT/
LATCH - REMOVAL) or (Refer to 23 - BODY/DOOR -
REAR/LATCH - REMOVAL).
OPERATION
The door ajar switches are actuated by the door
latch mechanisms. When a door is closed and prop-
erly latched, its door ajar switch is an open circuit.
When a door is open or only partially latched, the
door ajar switch is a closed circuit. The door ajar
switches are hard wired between a body ground and
the Body Control Module (BCM). The driver side
front door ajar switch is connected to the BCM
through a driver door ajar switch sense circuit, while
the remaining three door ajar switches are connected
to the BCM through a passenger door ajar switch
sense circuit in a parallel-series arrangement. The
BCM reads the door ajar switch status through an
internal pull-up, then uses these inputs to control
many electronic functions and features of the vehicle.
The door ajar switches can be diagnosed using con-
ventional diagnostic tools and methods; however, for
proper diagnosis of the BCM, and both the hard
wired and electronic BCM outputs affected by the
door ajar switch inputs, a DRBIIItscan tool is
required. Refer to the appropriate diagnostic infor-
mation.
FLIP-UP GLASS AJAR SWITCH
DESCRIPTION
A flip-up glass ajar switch is standard equipment
in this vehicle. This switch is concealed within and
integral to the flip-up glass latch unit. The switch is
a momentary leaf contact-type unit that is actuated
by the flip-up glass latch mechanism. A dedicated
connector receptacle on the flip-up glass latch unit
connects the flip-up glass ajar switch to the vehicle
electrical system through the tailgate wire harness.
The flip-up glass ajar switch cannot be adjusted or
repaired and, if faulty or damaged, the flip-up glass
latch unit must be replaced. (Refer to 23 - BODY/
SWING GATE/FLIP-UP GLASS LATCH - REMOV-
AL).
OPERATION
The flip-up glass ajar switch is actuated by the
flip-up glass latch mechanism. When the flip-up glass
is closed and properly latched, the flip-up glass ajar
switch is an open circuit. When the flip-up glass is
open or only partially latched, the flip-up glass ajar
switch is a closed circuit. The flip-up glass ajar
switch is hard wired between a body ground, the
Body Control Module (BCM), and the rear wiper
motor. The output of the switch is connected to the
BCM and rear wiper motor through a flip-up glass
ajar switch sense circuit. The BCM reads the flip-up
glass ajar switch status through an internal pull-up,
then uses this input to control many electronic func-

TAILGATE AJAR SWITCH
DESCRIPTION
A tailgate ajar switch is standard equipment in
this vehicle. This switch is concealed within and inte-
gral to the tailgate latch unit. The switch is a
momentary leaf contact-type unit that is actuated by
the tailgate latch mechanism. A pigtail wire harness
and connector on the tailgate latch unit connects the
tailgate ajar switch to the vehicle electrical system
through the tailgate wire harness. The tailgate ajar
switch cannot be adjusted or repaired and, if faulty
or damaged, the tailgate latch unit must be replaced.
(Refer to 23 - BODY/SWING GATE/LATCH -
REMOVAL).
OPERATION
The tailgate switch is actuated by the tailgate
latch mechanism. When the tailgate is closed and
properly latched, the tailgate ajar switch is an open
circuit. When the tailgate is open or only partially
latched, the tailgate ajar switch is a closed circuit.
The tailgate ajar switch is hard wired between a
body ground and the Body Control Module (BCM).
The output of the switch is connected to the BCM
through a tailgate ajar switch sense circuit. The
BCM reads the tailgate ajar switch status through
an internal pull-up, then uses this input to control
many electronic functions and features of the vehicle.
The tailgate ajar switch can be diagnosed using con-
ventional diagnostic tools and methods; however, for
proper diagnosis of the BCM, and both the hard
wired and electronic BCM outputs affected by the
tailgate ajar switch input, a DRBIIItscan tool is
required. Refer to the appropriate diagnostic infor-
mation.

The tailgate will lock and can not be unlocked if
the rear wiper switch is activated. The tailgate will
also lock if battery power is lost and then restored.
The tailgate/flip-up glass will not function with the
battery discharged or disconnected.
COMBINATION FLASHER
This flasher can be energized by the BCM to flash
all of the park/turn signal lamps as a optical alert for
the RKE panic function and, if the Flash Lights with
Lock programmable feature is enabled, as an optical
verification for the RKE lock event.
HORN RELAY
This relay can be energized by the BCM to sound
the horns as an audible alert for the RKE panic func-
tion and, if the Sound Horn on Lock programmable
feature is enabled, as an audible verification for the
RKE lock event.
LOW BEAM HEADLAMP RELAY
This relay can be energized by the BCM to flash
the headlamp low beams as an optical alert for the
RKE panic function.
OPERATION
POWER LOCKS
The Body Control Module (BCM) locks or unlocks
the doors when an actuation input signal from a door
lock switch or Remote Keyless Entry Module (RKE)
is received. The BCM turns on the output drivers
and provides a voltage level to the door lock motor
for a specified time. All passenger doors can be
locked or unlocked using a mechanical button
mounted on the door trim panel. The front passenger
doors and tailgate can be locked or unlocked by using
the key cylinder (tailgate cylinder does not lock/un-
lock vehicle. It only unlocks the tailgate). The tail-
gate will lock and can not be unlocked if the rear
wiper switch is activated (this prevents the wiper
from operating when the tailgate is ajar). The tail-
gate will also lock if battery power is lost and then
restored.
AUTOMATIC DOOR LOCKS
When the automatic door locks are ENABLED the
door locks will lock when the vehicle is moving at
about 25.7 Km/h (15 mph), all doors are closed and
the accelerator pedal is depressed. This feature can
be switched ON or OFF as desired. When the system
is DISABLED the door locks will operate normally,
but will not lock automatically when the vehicle is
rolling. Once the automatic door locks have been
actuated, they will not try to lock the doors again
until a door is opened.
DOOR LOCK INHIBIT
If the key is in the ignition, in any position, and
either front door is ajar, the doors can not be locked,
but the unlock function still operates. Pressing the
RKE lock/unlock button under these conditions will
result in a normal lock/unlock activation.
After the key is removed from the Ignition Switch,
or the doors are closed, the power door locks will
operate normally.
DOOR LOCK CIRCUIT PROTECTION
The BCM controls the door lock relays. If the door
lock switch is actuated continuously for more than
five seconds the BCM will turn the output driver
OFF (the BCM would consider the switch stuck).
Each lock motor is protected with a Positive Temper-
ature Coefficient device that prevents motor burn
out.
REMOTE KEYLESS ENTRY
²LOCK: Pressing the LOCK button locks all
doors, sounds horn (chirp) if enabled, and arms the
Vehicle Theft Security System, if enabled. The chirp
verifies that the RKE receiver has sent a message to
the BCM for door lock operation. If a door has not
been closed before pressing the LOCK button, the
vehicle may not be secured and the VTSS (if
equipped) will not arm until the door is closed.
²UNLOCK: Pressing the UNLOCK button once
will unlock the driver's door and activate the illumi-
nated entry system and disarm Vehicle Theft Secu-
rity System, if equipped. Pressing the UNLOCK
button twice within five seconds will unlock all doors.
²TAILGATE: Pressing the TAILGATE BUTTON
unlocks the tailgate remotely and opens the flip-up
glass.
²PANIC: Pressing the PANIC button sounds the
horns at half second intervals, flashes the exterior
lamps, and turns ON the interior lamps. The panic
alarm will remain on for three minutes, or until the
PANIC button is actuated again or the ignition
switch is turned to the RUN position.
The Remote Keyless Entry Module is capable of
retaining the transmitter Vehicle Access Code(s) in
its memory even after vehicle power has been inter-
rupted.
DIAGNOSIS AND TESTING - POWER LOCKS
The Body Control Module (BCM) enters a
reduced power mode after the key is turned
OFF. All diagnosis and testing of the power lock
system must be done with the key in the ON
position unless otherwise stated.
The most reliable, efficient, and accurate
means to diagnose the power lock system
requires the use of a DRBIIItscan tool and the

VEHICLE THEFT SECURITY
DESCRIPTION
The Vehicle Theft Security System (VTSS) is an
available factory-installed option on this model (Fig.
1). The VTSS is comprised of two primary sub-
systems: Vehicle Theft Alarm (VTA) and Sentry Key
Immobilizer System (SKIS). The VTA is an active
system that provides visual and audible responses as
deterrents to and warnings of unauthorized vehicle
tampering. The SKIS is a passive system that effec-
tively immobilizes the vehicle against unauthorized
operation. Following are paragraphs which describe
the various components that are included in each of
these subsystems of the VTSS.
Hard wired circuitry connects many of the VTSS
components to each other through the electrical sys-
tem of the vehicle. These hard wired circuits are
integral to several wire harnesses, which are routed
throughout the vehicle and retained by many differ-
ent methods. These circuits may be connected to each
other, to the vehicle electrical system and to the
VTSS components through the use of a combination
of soldered splices, splice block connectors, and many
different types of wire harness terminal connectorsand insulators. Refer to the appropriate wiring infor-
mation. The wiring information includes wiring dia-
grams, proper wire and connector repair procedures,
further details on wire harness routing and reten-
tion, as well as pin-out and location views for the
various wire harness connectors, splices and grounds.
VEHICLE THEFT ALARM The VTA is available in
two different configurations for this vehicle: One con-
figuration is designed for vehicles manufactured for
sale in North America; while, the other configuration
is designed for vehicles manufactured for sale in
markets outside of North America, also referred to as
Rest-Of-World or ROW. In addition, the VTA for
ROW is available in two versions: base and premium.
All vehicles equipped with VTA are also equipped
with the Remote Keyless Entry (RKE) system and
the Sentry Key Immobilizer System (SKIS), regard-
less of their market destination. The North American
and ROW base version of the VTA provides perimeter
vehicle protection by monitoring the vehicle doors,
the tailgate, the rear flip-up glass and, for vehicles
built for certain markets where it is required equip-
ment, the hood. If unauthorized vehicle use or tam-
pering is detected, these systems respond by pulsing
the horn and flashing certain exterior lamps. The
ROW premium version of the VTA is only available

ajar switch, the power lock switches and, in vehicles
built for certain markets where it is required, the
hood ajar switch. The programming in the BCM
allows it to process the information from all of these
inputs and send control outputs to energize or de-en-

ergize the combination flasher, the horn relay (except
vehicles with the Rest-Of-World or ROW premium
version of the VTA), and the security indicator. In
addition, in vehicles built for certain markets where
the ROW premium version of the VTA is required,
the BCM also exchanges electronic messages with
the Intrusion Transceiver Module (ITM) over the Pro-
grammable Communications Interface (PCI) data bus
network to provide the features found in this version
of the VTA.
The hard wired circuits and components of the
VTA may be diagnosed and tested using conventional
diagnostic tools and procedures. However, conven-
tional diagnostic methods may not prove conclusive
in the diagnosis of the Body Control Module (BCM),
the ElectroMechanical Instrument Cluster (EMIC),
the Intrusion Transceiver Module (ITM), or the Pro-
grammable Communications Interface (PCI) data bus
network. The most reliable, efficient, and accurate
means to diagnose the BCM, the EMIC, the ITM,
and the PCI data bus network inputs and outputs
related to the VTA requires the use of a DRBIIIt
scan tool. Refer to the appropriate diagnostic infor-
mation. Following are paragraphs that briefly
describe the operation of each of the VTA features.
See the owner's manual in the vehicle glove box for
more information on the features, use and operation
of the VTA.
²ENABLING- The BCM must have the VTA
function electronically enabled in order for the VTA
to perform as designed. The logic in the BCM keeps
its VTA function dormant until it is enabled using a
DRBIIItscan tool. The VTA function of the BCM is
enabled on vehicles equipped with the VTA option at
the factory, but a service replacement BCM must be
VTA-enabled by the dealer using a DRBIIItscan
tool. Refer to the appropriate diagnostic information.
²PRE-ARMING- The VTA has a pre-arming
sequence. Pre-arming occurs when a door, the tail-
gate, or the flip-up glass is open when the vehicle is
locked using a power lock switch, or when the ªLockº
button on the Remote Keyless Entry (RKE) transmit-
ter is depressed. The power lock switch will not ini-
tiate the pre-arming sequence if the key is in the
ignition switch. When the VTA is pre-armed, the
arming sequence is delayed until all of the doors, the
tailgate, and the flip-up glass are closed.
²ARMING- Passive arming of the VTA occurs
when the vehicle is exited with the key removed from
the ignition switch and the doors are locked while
they are open using the power lock switch (see Pre-
Arming). Active arming of the VTA occurs when the
ªLockº button on the Remote Keyless Entry (RKE)
transmitter is depressed to lock the vehicle after all
of the doors, the tailgate, and the flip-up glass are
closed. The VTA will not arm if the doors are lockedusing the key in a lock cylinder or using a mechani-
cal lock button. Once the VTA begins the passive or
active arming sequence, the security indicator in the
instrument cluster will flash rapidly for about six-
teen seconds. This indicates that the VTA arming
sequence is in progress. If the ignition switch is
turned to the On position, if a door is unlocked with
the power lock switch or the RKE transmitter, or if
the tailgate is unlocked by any means during the six-
teen second arming sequence, the security indicator
will stop flashing and the VTA arming sequence will
abort. On vehicles equipped with the hood ajar
switch, the VTA arming sequence will occur regard-
less of whether the hood is open or closed, but the
underhood area will not be protected unless the hood
is closed when the VTA arming sequence begins.
Also, if the status of the hood ajar switch changes
from open (hood closed) to closed (hood open) during
the sixteen second arming sequence, the security
indicator will stop flashing and the VTA arming
sequence will abort. Once the sixteen second arming
sequence is successfully completed, the security indi-
cator will flash at a slower rate, indicating that the
VTA is armed.
²DISARMING- For vehicles built for the North
American market, disarming of the VTA occurs when
the vehicle is unlocked using the key to unlock a door
or the tailgate. Disarming of the VTA for any market
also occurs when the vehicle is unlocked by depress-
ing the ªUnlockº button of the Remote Keyless Entry
(RKE) transmitter, or by turning the ignition switch
to the On position using a valid Sentry Key Immobi-
lizer System (SKIS) key. Once the alarm has been
activated, any of these disarming methods will also
deactivate the alarm.
²POWER-UP MODE- When the armed VTA
senses that the battery has been disconnected and
reconnected, it enters its power-up mode. In the pow-
er-up mode the alarm system returns to the mode
that was last selected prior to the battery failure or
disconnect. If the VTA was armed prior to the battery
disconnect or failure, the technician or vehicle opera-
tor will have to actively or passively disarm the sys-
tem after the battery is reconnected. The power-up
mode will also apply if the battery goes dead while
the system is armed, and battery jump-starting is
then attempted. The VTA will remain armed until
the technician or vehicle operator has actively or pas-
sively disarmed the system. If the VTA is in the dis-
armed mode prior to a battery disconnect or failure,
it will remain disarmed after the battery is recon-
nected or replaced, or if jump-starting is attempted.
²ALARM- The VTA alarm output varies by the
version of the VTA with which the vehicle is
equipped. In all cases, the alarm provides both visual
and audible outputs; however, the time intervals of
8Q - 4 VEHICLE THEFT SECURITYKJ
VEHICLE THEFT SECURITY (Continued)

these outputs vary by the requirements of the mar-
ket for which the vehicle is manufactured. In all
cases, the visual output will be a flashing on and off
of the exterior lamps. For vehicles equipped with the
North American or the ROW base version of the
VTA, the audible output will be a pulsing of the horn.
For vehicles with the ROW premium version of the
VTA, the audible output will be a cycling of the
alarm siren. See the owner's manual in the vehicle
glove box for details of the alarm output require-
ments of the specific market for which the vehicle
was manufactured. The inputs that will trigger the
alarm include the door ajar switches, the tailgate
ajar switch, the flip-up glass ajar switch, and in vehi-
cles built for certain markets where they are
required, the hood ajar switch and the Intrusion
Transceiver Module (ITM).
²TAMPER ALERT- The VTA tamper alert fea-
ture will pulse the horn (or the alarm siren for the
ROW premium version of the VTA) three times upon
VTA disarming, if the alarm was triggered and has
since timed-out. This feature alerts the vehicle oper-
ator that the VTA alarm was activated while the
vehicle was unattended.
²INTRUSION ALARM- The intrusion alarm is
an exclusive feature of the ROW premium version of
the VTA, which is only available in certain markets
where it is required. When the VTA is armed, a
motion sensor in the Intrusion Transceiver Module
(ITM) monitors the interior of the vehicle for move-
ment. If motion is detected, the ITM sends an elec-
tronic message to the BCM over the PCI data bus to
invoke the visual alarm feature, and sends an elec-
tronic message to the alarm siren in the engine com-
partment over a dedicated serial bus to invoke the
audible alarm feature. The motion detect feature of
the ITM can be disabled by depressing the ªLockº
button on the RKE transmitter three times within
fifteen seconds during VTA arming, while the secu-
rity indicator is still flashing rapidly. The VTA pro-
vides a single short siren ªchirpº as an audible
confirmation that the motion detect disable request
has been received. The ITM must be electronically
enabled in order for the intrusion alarm to perform
as designed. The logic in the ITM keeps its intrusion
alarm function dormant until it is enabled using a
DRBIIItscan tool. The intrusion alarm function of
the ITM is enabled on vehicles equipped with thisoption at the factory, but a service replacement ITM
must be configured and enabled by the dealer using a
DRBIIItscan tool. Refer to the appropriate diagnos-
tic information.
SENTRY KEY IMMOBILIZER SYSTEM The Sen-
try Key Immobilizer System (SKIS) is designed to
provide passive protection against unauthorized vehi-
cle use by disabling the engine after about two sec-
onds of running, whenever any method other than a
valid Sentry Key is used to start the vehicle. The
SKIS is considered a passive protection system
because it is always active when the ignition system
is energized and does not require any customer inter-
vention. The SKIS uses Radio Frequency (RF) com-
munication to obtain confirmation that the key in the
ignition switch is a valid key for operating the vehi-
cle. The microprocessor-based SKIS hardware and
software also use electronic messages to communi-
cate with other electronic modules in the vehicle over
the Programmable Communications Interface (PCI)
data bus. (Refer to 8 - ELECTRICAL/ELECTRONIC
CONTROL MODULES/COMMUNICATION - OPER-
ATION).
Pre-programmed Sentry Key transponders are pro-
vided with the vehicle from the factory. Each Sentry
Key Immobilizer Module (SKIM) will recognize a
maximum of eight Sentry Keys. If the customer
would like additional keys other than those provided
with the vehicle, they may be purchased from any
authorized dealer. These additional keys must be pro-
grammed to the SKIM in the vehicle in order for the
system to recognize them as valid keys. This can be
done by the dealer using a DRBIIItscan tool or, if
Customer Learn programming is an available SKIS
feature in the market where the vehicle was pur-
chased, the customer can program the additional
keys, as long as at least two valid Sentry Keys are
already available. (Refer to 8 - ELECTRICAL/VEHI-
CLE THEFT SECURITY - STANDARD PROCE-
DURE - TRANSPONDER PROGRAMMING).
The SKIS performs a self-test each time the igni-
tion switch is turned to the On position, and will
store fault information in the form of Diagnostic
Trouble Codes (DTC's) if a system malfunction is
detected. The SKIS can be diagnosed, and any stored
DTC's can be retrieved using a DRBIIItscan tool.
Refer to the appropriate diagnostic information.
