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

Typically, the vehicle occupants recall more about
the events preceding and following a collision than
they have of an airbag deployment itself. This is
because the airbag deployment and deflation occur so
rapidly. In a typical 48 kilometer-per-hour (30 mile-
per-hour) barrier impact, from the moment of impact
until the airbags are fully inflated takes about 40
milliseconds. Within one to two seconds from the
moment of impact, the airbags are almost entirely
deflated. The times cited for these events are approx-
imations, which apply only to a barrier impact at the
given speed. Actual times will vary somewhat,
depending upon the vehicle speed, impact angle,
severity of the impact, and the type of collision.
When the ACM monitors a problem in any of the
dual front airbag system circuits or components,
including the seat belt tensioner, it stores a fault
code or Diagnostic Trouble Code (DTC) in its memory
circuit and sends an electronic message to the EMIC
to turn on the airbag indicator. When the SIACM
monitors a problem in any of the side curtain airbag
system circuits or component, it stores a fault code or
Diagnostic Trouble Code (DTC) in its memory circuit
and sends an electronic message to the ACM, and the
ACM sends an electronic message to the EMIC to
turn on the airbag indicator. Proper testing of the
airbag system components, the Programmable Com-
munication Interface (PCI) data bus, the data bus
message inputs to and outputs from the EMIC, the
SIACM, or the ACM, as well as the retrieval or era-
sure of a DTC from the ACM, SIACM, or EMIC
requires the use of a DRBIIItscan tool. Refer to the
appropriate diagnostic information.
See the owner's manual in the vehicle glove box for
more information on the features, use and operation
of all of the factory-installed passive restraints.

KJRESTRAINTS 8O - 5
RESTRAINTS (Continued)

Following are paragraphs that briefly describe the
operation of each of the front wiper and washer sys-
tem operating modes.
CONTINUOUS WIPE MODE When the Low posi-
tion of the control knob on the right (wiper) control
stalk of the multi-function switch is selected, the
Body Control Module (BCM) energizes the wiper
on/off relay. This directs battery current through the
normally open contacts of the energized wiper on/off
relay and the normally closed contacts of the de-en-
ergized wiper high/low relay to the low speed brush
of the front wiper motor, causing the front wipers to
cycle at low speed. When the High position of the
control knob is selected, the BCM energizes both the
wiper on/off relay and the wiper high/low relay. This
directs battery current through the normally open
contacts of the energized wiper on/off relay and the
normally open contacts of the energized wiper high/
low relay to the high speed brush of the front wiper
motor, causing the front wipers to cycle at high
speed.
When the Off position of the control knob is
selected, the BCM de-energizes both the wiper on/off
and wiper high low relays, then one of two events
will occur. The event that occurs depends upon the
position of the wiper blades on the windshield at the
moment that the control knob Off position is selected.
If the wiper blades are in the down position on the
windshield when the Off position is selected, the
park switch that is integral to the front wiper motor
is closed to ground and the wiper motor ceases to
operate. If the wiper blades are not in the down posi-
tion on the windshield at the moment the Off posi-
tion is selected, the park switch is closed to battery
current from the fused ignition switch output (run-
acc) circuit of the front wiper motor. The park switch
directs this battery current to the low speed brush of
the wiper motor through the wiper park switch sense
circuit and the normally closed contacts of the de-en-
ergized wiper on/off and wiper high/low relays. This
causes the wiper motor to continue running at low
speed until the wiper blades are in the down position
on the windshield and the park switch is again
closed to ground.
INTERMITTENT WIPE MODE When the control
knob on the right (wiper) control stalk of the multi-
function switch is moved to one of the Delay interval
positions, the BCM electronic intermittent wipe logic
circuit responds by calculating the correct length of
time between wiper sweeps based upon the selected
delay interval input. The BCM monitors the chang-
ing state of the wiper motor park switch through a
hard wired front wiper park switch sense circuit
input. This input allows the BCM to determine the
proper intervals at which to energize and de-energize
the wiper on/off relay to operate the front wipermotor intermittently for one low speed cycle at a
time. The BCM logic is also programmed to provide
an immediate wipe cycle and begin a new delay
interval timing cycle each time a shorter delay inter-
val is selected, and to add the remaining delay tim-
ing interval to the new delay interval timing before
the next wipe cycle occurs each time a longer delay
interval is selected.
MIST WIPE MODE When the right (wiper) control
stalk of the multi-function switch is moved to the
momentary Mist position, the BCM energizes the
wiper on/off relay for as long as the Mist switch is
held closed, then de-energizes the relay when the
state of the Mist switch input changes to open. The
BCM can operate the front wiper motor in this mode
for only one low speed cycle at a time, or for an
indefinite number of sequential low speed cycles,
depending upon how long the Mist switch is held
closed.
WASH MODE When the right (wiper) control stalk
of the multi-function switch is moved to the momen-
tary front Wash position while the control knob is in
the Low or High positions, the circuitry within the
switch directs battery current and ground to the
washer pump/motor unit. This will cause the washer
pump/motor unit to be energized for as long as the
front Wash switch is held closed, and to de-energize
when the front Wash switch is released. When the
right (wiper) control stalk of the multi-function
switch is moved to the momentary front Wash posi-
tion while the control knob is in one of the Delay
interval positions, the front washer pump/motor oper-
ation is the same. However, the BCM energizes the
wiper on/off relay to override the selected delay inter-
val and operate the front wiper motor in a continu-
ous low speed mode for as long as the front Wash
switch is held closed, then de-energizes the relay and
reverts to the selected delay mode interval several
wipe cycles after the front Wash switch is released.
The BCM detects the front Wash switch state
through a hard wired washer pump driver circuit
input from the multi-function switch.
WIPE-AFTER-WASH MODE When the right
(wiper) control stalk of the multi-function switch is
moved to the momentary front Wash position while
the control knob is in the Off position, the BCM
detects that switch state through a hard wired
washer pump driver circuit input from the multi-
function switch. The BCM responds to this input by
energizing the wiper on/off relay for as long as the
Wash switch is held closed, then de-energizes the
relay several wipe cycles after the front Wash switch
is released. The BCM monitors the changing state of
the wiper motor park switch through a hard wired
front wiper park switch sense circuit input. This
input allows the BCM to count the number of wipe

pump/motor unit. If not OK, repair the open washer
pump sense circuit between the washer pump/motor
unit and the multi-function switch as required.
CLEANING - FRONT WIPER & WASHER
SYSTEM
FRONT WIPER SYSTEM
The squeegees of wiper blades exposed to the ele-
ments for a long time tend to lose their wiping effec-
tiveness. Periodic cleaning of the squeegees is
suggested to remove any deposits of salt or road film.
The wiper blades, arms, and windshield glass should
only be cleaned using a sponge or soft cloth and
windshield washer fluid, a mild detergent, or a non-
abrasive cleaner. If the wiper blades continue to
leave streaks, smears, hazing, or beading on the
glass after thorough cleaning of the squeegees and
the glass, the entire wiper blade assembly must be
replaced.
CAUTION: Protect the rubber squeegees of the
wiper blades from any petroleum-based cleaners,
solvents, or contaminants. These products can rap-
idly deteriorate the rubber squeegees.FRONT WASHER SYSTEM
If the washer system is contaminated with foreign
material, drain the washer reservoir by removing the
washer pump/motor from the reservoir. Clean foreign
material from the inside of the washer pump/motor
inlet filter screen and the washer reservoir using
clean washer fluid, a mild detergent, or a non-abra-
sive cleaner. Flush foreign material from the washer
system plumbing by first disconnecting the washer
hoses from the washer nozzles, then running the
washer pump/motor to run clean washer fluid or
water through the system. Plugged or restricted
washer nozzles should be carefully back-flushed
using compressed air. If the washer nozzle obstruc-
tion cannot be cleared, replace the washer nozzle.
CAUTION: Never introduce petroleum-based clean-
ers, solvents, or contaminants into the washer sys-
tem. These products can rapidly deteriorate the
rubber seals and hoses of the washer system, as
well as the rubber squeegees of the wiper blades.
CAUTION: Never use compressed air to flush the
washer system plumbing. Compressed air pres-
sures are too great for the washer system plumbing
components and will result in further system dam-
age. Never use sharp instruments to clear a
plugged washer nozzle or damage to the nozzle ori-
fice and improper nozzle spray patterns will result.
INSPECTION - FRONT WIPER & WASHER
SYSTEM
FRONT WIPER SYSTEM
The front wiper blades and wiper arms should be
inspected periodically, not just when wiper perfor-
mance problems are experienced. This inspection
should include the following points:
(1) Inspect the wiper arms for any indications of
damage, or contamination. If the wiper arms are con-
taminated with any foreign material, clean them as
required. (Refer to 8 - ELECTRICAL/FRONT WIP-
ERS/WASHERS - CLEANING). If a wiper arm is
damaged or corrosion is evident, replace the wiper
arm with a new unit. Do not attempt to repair a
wiper arm that is damaged or corroded.
(2) Carefully lift the wiper blade off of the glass.
Note the action of the wiper arm hinge. The wiper
arm should pivot freely at the hinge, but with no lat-
eral looseness evident. If there is any binding evident
in the wiper arm hinge, or there is evident lateral
play in the wiper arm hinge, replace the wiper arm.
KJFRONT WIPERS/WASHERS 8R - 7
FRONT WIPERS/WASHERS (Continued)

OPERATION
The front check valve provides more than one func-
tion in this application. It serves as a wye connector
fitting between the cowl grille panel and washer noz-
zle sections of the front washer supply hose. It also
prevents washer fluid from draining out of the front
washer supply hoses back to the washer reservoir.
This drain-back would result in a lengthy delay when
the front washer switch is actuated until washer
fluid was dispensed through the front washer noz-
zles, because the washer pump would have to refill
the front washer plumbing from the reservoir to the
nozzles. Finally, the front check valve prevents
washer fluid from siphoning through the front
washer nozzles after the front washer system is
turned Off.
Within the check valve body, a small check valve is
held in place against a seat by a small coiled spring
to restrict flow through the unit until the valve is
unseated by a predetermined inlet fluid pressure.
When the washer pump pressurizes and pumps
washer fluid from the reservoir through the front
washer plumbing, the fluid pressure overrides the
spring pressure applied to the check valve and
unseats the valve, allowing washer fluid to flow
toward the front washer nozzles. When the washer
pump stops operating, spring pressure seats the
check valve and fluid flow in either direction within
the front washer plumbing is prevented.
REMOVAL
(1) Unlatch and open the hood.
(2) Remove both front wiper arms from the wiper
pivots. (Refer to 8 - ELECTRICAL/WIPERS/WASH-
ERS - FRONT/FRONT WIPER ARM - REMOVAL).
(3) Remove the cowl plenum cover/grille panel
from over the cowl plenum. (Refer to 23 - BODY/EX-
TERIOR/COWL GRILLE - REMOVAL).

²Do not hammer or pound on plastic trim panel
when servicing interior trim. Plastic panels can
break.
DaimlerChrysler Corporation uses many different
types of push-in fasteners to secure the interior and
exterior trim to the body. Most of these fasteners can
be reused to assemble the trim during various repair
procedures. At times, a push-in fastener cannot be
removed without damaging the fastener or the com-
ponent it is holding. If it is not possible to remove a
fastener without damaging a component or body, cut
or break the fastener and use a new one when
installing the component. Never pry or pound on a
plastic or pressed-board trim component. Using a
suitable fork-type prying device, pry the fastener
from the retaining hole behind the component being
removed. When installing, verify fastener alignment
with the retaining hole by hand. Push directly on or
over the fastener until it seats. Apply a low-force pull
to the panel to verify that it is secure.
When it is necessary to remove components to ser-
vice another, it should not be necessary to apply
excessive force or bend a component to remove it.
Before damaging a trim component, verify hidden
fasteners or captured edges holding the component in
place.
