DIAGNOSIS AND TESTING - POWER LOCK &
REMOTE KEYLESS ENTRY SYSTEM
The following tests include a preliminary diagnosis
for the power lock system usedonlyon vehicles
equipped with the optional Remote Keyless Entry
(RKE) system, which includes a high-line or premium
Central Timer Module (CTM). These testsdo not
apply to the diagnosis of the power lock system on
vehicles equipped with a base version of the CTM.
(Refer to 8 - ELECTRICAL/POWER LOCKS - DIAG-
NOSIS AND TESTING - POWER LOCK SYSTEM).
These tests will help to diagnose the hard wired
components and circuits of the power lock system.
However, these tests may not prove conclusive in the
diagnosis of this system. In order to obtain conclusive
testing of the power lock and RKE system, the
Chrysler Collision Detection (CCD) data bus network
and all of the electronic modules that provide inputs
to, or receive outputs from the power lock and RKE
system components must be checked.
The most reliable, efficient, and accurate means to
diagnose the power lock and RKE system requires
the use of a DRBIIItscan tool. The DRBIIItscan
tool can provide confirmation that the CCD data bus
is functional, that all of the electronic modules are
sending and receiving the proper messages on the
CCD data bus, that the CTM is receiving the proper
hard wired inputs, and that the power lock motors
are being sent the proper hard wired outputs by the
CTM.
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.
PRELIMINARY TESTS
To begin this test, note the system operation while
you actuate both the Lock and Unlock functions with
the power lock switches, the door cylinder lock
switches, and the RKE transmitter. Then, proceed as
follows:
²If the entire power lock system fails to function
with the power lock switches, the door cylinder lock
switches, or the RKE transmitter, check the fused
B(+) fuse in the Junction Block (JB). If the fuse is
OK, proceed to the diagnosis of the power lock
motors. (Refer to 8 - ELECTRICAL/POWER LOCKS/
POWER LOCK MOTOR - DIAGNOSIS AND TEST-
ING).
²If the power lock system functions with both
power lock switches, and both door cylinder lock
switches, but not with the RKE transmitter, proceed
to the diagnosis of the transmitter. (Refer to 8 -
ELECTRICAL/POWER LOCKS/REMOTE KEYLESSENTRY TRANSMITTER - DIAGNOSIS AND TEST-
ING).
²If the entire power lock system functions with
the RKE transmitter, and both door cylinder lock
switches, but not with one or both of the power lock
switches, proceed to diagnosis of the power lock
switches. (Refer to 8 - ELECTRICAL/POWER
LOCKS/POWER LOCK SWITCH - DIAGNOSIS AND
TESTING).
²If the entire power lock system functions with
the RKE transmitter, and both power lock switches,
but not with one or both of the door cylinder lock
switches, proceed to diagnosis of the door cylinder
lock switches. (Refer to 8 - ELECTRICAL/POWER
LOCKS/DOOR CYLINDER LOCK SWITCH - DIAG-
NOSIS AND TESTING).
²If one power lock motor fails to operate with
both of the power lock switches, both of the door cyl-
inder lock switches and/or the RKE transmitter, pro-
ceed to diagnosis of the power lock motor. (Refer to 8
- ELECTRICAL/POWER LOCKS/POWER LOCK
MOTOR - DIAGNOSIS AND TESTING).
If the problem being diagnosed is related to one or
more of the electronic features (automatic locks, door
lock inhibit, enhanced accident response, illuminated
entry, panic mode, or RKE horn chirp), further diag-
nosis should be performed using a DRBIIItscan tool.
Refer to the appropriate diagnostic information.
DOOR CYLINDER LOCK
SWITCH
DESCRIPTION
A door cylinder lock switch is snapped onto the
back of the key lock cylinder inside each front door of
vehicles equipped with a high-line or premium Cen-
tral Timer Module (CTM). The door cylinder lock
switch is a resistor multiplexed momentary switch
that is hard wired in series between a body ground
and the CTM through the front door wire harness.
The door cylinder lock switches are driven by the key
lock cylinders and contain three internal resistors.
One resistor is used for the neutral switch position,
one for the Lock position, and one for the Unlock
position.
The door cylinder lock switches cannot be adjusted
or repaired and, if faulty or damaged, they must be
replaced.
OPERATION
The door cylinder lock switches are actuated by the
key lock cylinder when the key is inserted in the lock
cylinder and turned to the lock or unlock positions.
The door cylinder lock switch closes a path to ground
through one of three internal resistors for the Cen-

POWER WINDOWS
DESCRIPTION
Power windows are available as factory-installed
optional equipment on this model. The power lock
system is included on vehicles equipped with the
power window option.
OPERATION
The power window system allows each of the front
door windows to be raised and lowered electrically by
actuating a switch on the trim panel of each respec-
tive door. Additionally, the master switch on the
driver side door trim panel allows the driver to raise
or lower the passenger side front door window. The
power window system receives battery feed through a
circuit breaker in the junction block, only when the
ignition switch is in the On position.
The power window system includes the power win-
dow switches on each front door trim panel, the cir-
cuit breaker in the junction block, and the power
window motors inside each front door. This group
covers diagnosis and service of only the electrical
components in the power window system. For service
of mechanical components, such as the regulator, lift
plate, window tracks, or glass refer to Group 23 -
Body.
Refer to the owner's manual in the vehicle glove
box for more information on the features, use and
operation of the power window system.
DIAGNOSIS AND TESTING - POWER
WINDOWS
For circuit descriptions and diagrams, refer to the
appropriate wiring information. The wiring informa-
tion includes wiring diagrams, proper wire and con-
nector repair procedures, details of wire harnessrouting and retention, connector pin-out information
and location views for the various wire harness con-
nectors, splices and grounds.
ALL WINDOWS INOPERATIVE
(1) Check the circuit breaker in the junction block.
If OK, go to Step 2. If not OK, replace the faulty cir-
cuit breaker.
(2) Disconnect and isolate the battery negative
cable. Remove the power window and lock switch and
bezel unit from the driver side front door trim panel.
Unplug the wire harness connector from the switch
and bezel unit.
(3) Check for continuity between the ground cir-
cuit cavity of the switch and bezel unit wire harness
connector and a good ground. If OK, (Refer to 8 -
ELECTRICAL/POWER WINDOWS/POWER WIN-
DOW SWITCH - DIAGNOSIS AND TESTING). If not
OK, repair the circuit to ground as required.
ONE WINDOW INOPERATIVE
The window glass must be free to slide up and
down for the power window motor to function prop-
erly. If the glass is not free to move up and down, the
motor will overload and trip the integral circuit
breaker. To determine if the glass is free, disconnect
the regulator plate from the glass. Then slide the
window up and down by hand.
There is an alternate method to check if the glass
is free. Position the glass between the up and down
stops. Then, shake the glass in the door. Check that
the glass can be moved slightly from side to side,
front to rear, and up and down. Then check that the
glass is not bound tight in the tracks. If the glass is
free, proceed with the diagnosis that follows. If the
glass is not free, (Refer to 23 - BODY/DOOR -
FRONT/DOOR GLASS - REMOVAL).
BR/BEPOWER WINDOWS 8N - 23

(1) Disconnect and isolate the battery negative
cable. Remove the power window and lock switch and
bezel unit from the door trim panel on the side of the
vehicle with the inoperative window. Unplug the wire
harness connector from the switch and bezel unit.
(2) Connect the battery negative cable. Turn the
ignition switch to the On position. Check for battery
voltage at the fused ignition switch output (run) cir-
cuit cavity in the body half of the switch and bezel
unit wire harness connector. If OK, and the inopera-
tive power window is on the driver side, go to Step 4.
If OK, and the inoperative power window is on the
passenger side, go to Step 3. If not OK, repair the
open circuit to the junction block as required.
(3) Disconnect and isolate the battery negative
cable. Check for continuity between each of the two
master window switch right up/down control circuit
cavities in the body half of the passenger side switch
and bezel unit wire harness connector and a good
ground. In each case, there should be continuity. If
OK, go to Step 4. If not OK, repair the open circuit to
the driver side switch and bezel unit as required.
(4) Test the power window switch continuity.
(Refer to 8 - ELECTRICAL/POWER WINDOWS/
POWER WINDOW SWITCH - DIAGNOSIS AND
TESTING). If OK, go to Step 5. If not OK, replace
the faulty power window and lock switch and bezel
unit.
(5) 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. Check
the continuity in each circuit between the inoperative
power window and lock switch and bezel unit wire
harness connector cavities and the corresponding
power window motor wire harness connector cavities.
If OK, (Refer to 8 - ELECTRICAL/POWER WIN-
DOWS/WINDOW MOTOR - DIAGNOSIS AND TEST-
ING). If not OK, repair the open circuit(s) as
required.
NOTE: The passenger side power window switch
receives the ground feed for operating the passen-
ger side power window motor through the driver
side power window switch and wire harness con-
nector.
POWER WINDOW SWITCH
DESCRIPTION
The power windows are controlled by two-way
switches integral to the power window and lock
switch and bezel unit on the trim panel of each frontdoor. A second power window switch in the driver
side switch and bezel unit allows the driver to control
the passenger side window. A Light-Emitting Diode
(LED) in the paddle of each switch is illuminated
whenever the ignition switch is in the On position.
OPERATION
The power window switch for the driver side front
door has an Auto label on it. This switch has a sec-
ond detent position beyond the normal Down position
that provides an automatic one-touch window down
feature. This feature is controlled by an electronic
circuit and a relay that are integral to the driver side
front door power window and lock switch unit.
The power window switches control the battery
and ground feeds to the power window motors. The
passenger side power window switch receives a
ground feed through the driver side power window
switch for operating the passenger side power win-
dow motor.
The power window and lock switch and bezel unit
cannot be repaired and, if faulty or damaged, the
entire switch and bezel unit must be replaced.
DIAGNOSIS AND TESTING - POWER WINDOW
SWITCH
The auto down feature of the driver side power
window switch is controlled by an electronic circuit
within the switch unit. The auto down circuitry is
activated when the driver side power window switch
is moved to the second detent in the Down direction.
The outputs from the auto down circuitry are carried
through the same switch pins that provide the nor-
mal down function. The auto down circuit cannot be
tested. If the driver side power window switch conti-
nuity tests are passed, but the auto down feature is
inoperative, replace the faulty driver side power win-
dow switch unit.
The Light-Emitting Diode (LED) illumination
lamps for all of the power window and lock switch
and bezel unit switch paddles receive battery current
through the power window circuit breaker in the
junction block. If all of the LEDs are inoperative in
either or both power window and lock switch and
bezel units and the power windows are inoperative,
perform the diagnosis for Power Window System in
this group. If the power windows operate, but any or
all of the LEDs are inoperative, the power window
and lock switch and bezel unit with the inoperative
LED(s) is faulty and must be replaced. For circuit
descriptions and diagrams, 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

PASSENGER AIRBAG ON/OFF
SWITCH
DESCRIPTION
The passenger airbag on-off switch is standard
equipment on this model when it is not equipped
with a full size rear seat. This switch is a single pole,
single throw switch with a single integral red Light-
Emitting Diode (LED), and a non-coded key cylinder-
type actuator. The switch is located in the upper
right corner of instrument panel cluster bezel, near
the center of instrument panel to make the Off indi-
cator visible to all front seat occupants. When the
BR/BERESTRAINTS 8O - 23
PASSENGER AIRBAG (Continued)

switch is in its installed position, the only compo-
nents visible through the dedicated opening of the
cluster bezel are the switch face plate and nomencla-
ture, the key cylinder actuator, and a small round
lens with the text9Off9imprinted on it. The ªOnº
position of the switch is designated by text imprinted
upon the face plate of the switch, but is not illumi-
nated. The remainder of the switch is concealed
behind the switch face plate and the instrument
panel cluster bezel.
The passenger airbag on-off switch housing is con-
structed of molded plastic and has three integral
mounting tabs. These mounting tabs are used to
secure the switch to the back of the molded plastic
switch face plate with three small screws. The
molded plastic face plate also has three integral
mounting tabs that are used to secure the switch and
face plate unit to the instrument panel carrier with
three additional screws. Two short pigtail wires with
molded plastic connector insulators exit the back of
the switch housing and connect the switch to the
vehicle electrical system through two dedicated take
outs of the instrument panel wire harness. The har-
ness take outs are equipped with molded plastic con-
nector insulators that are keyed and latched to
ensure proper and secure switch electrical connec-
tions. The passenger airbag on/off switch cannot be
adjusted or repaired and, if faulty or damaged, the
switch must be replaced.
OPERATION
The passenger airbag on/off switch allows the cus-
tomer to turn the passenger airbag function On or
Off to accommodate certain uses of the right front
seating position where airbag protection may not be
desired. See the owner's manual in the vehicle glove
box for specific recommendations on when to enable
or disable the passenger airbag. The Off indicator of
the switch will be illuminated whenever the switch is
turned to the Off position. The ignition key is the
only key or object that should ever be inserted into
the switch. The on/off switch requires only a partial
key insertion to fully depress a spring-loaded locking
plunger. The spring-loaded locking plunger prevents
the user from leaving the key in the switch. The key
will be automatically ejected when force is not
applied. To actuate the passenger side airbag on/off
switch, insert the ignition key into the switch key
actuator far enough to fully depress the plunger and
rotate to the desired switch position. When the
switch key actuator is rotated to its clockwise stop
(the key actuator slot will be aligned with the Off
indicator lamp), the Off indicator is illuminated and
the passenger airbag is disabled. When the switch is
rotated to its counterclockwise stop (the key actuator
slot will be in a vertical position), the Off indicatorwill be extinguished and the passenger airbag is
enabled.
The passenger airbag on/off switch is connected in
series between the Airbag Control Module (ACM) and
the passenger airbag inflator unit. When the switch
is in the On position, the switch connects the ACM
directly to the passenger airbag inflator. When the
switch is in the Off position it interrupts the inflator
circuits, but replaces the normal resistance in these
circuits with an internal resistor. Thus, the ACM is
unable to distinguish the mode of the switch and still
sends an electrical signal as though it were deploying
the passenger airbag when it detects a sufficient
impact. However, the switch position should not be
changed while the ignition switch is in the On posi-
tion, as the ACM may detect a fault, record a Diag-
nostic Trouble Code (DTC), and illuminate the Airbag
indicator in response to a momentary open it senses
in the passenger airbag inflator circuits as the on/off
switch changes states.
