DOOR CYLINDER LOCK
SWITCH
DESCRIPTION
The driver cylinder lock switch is integral to the
key lock cylinder inside the driver side front door.
The driver cylinder lock switch is a resistive multi-
plexed switch that is hard wired between a body
ground and the Driver Door Module (DDM) through
the front door wire harness. It maintains a path to
ground, and changes voltages through an internal
resistor when the lock cylinder is rotated to the lock
or unlock position.
The driver cylinder lock switch cannot be adjusted
or repaired and, if faulty or damaged, the driver side
front door lock cylinder unit must be replaced. (Refer
to 23 - BODY/DOOR - FRONT/LOCK CYLINDER -
REMOVAL) and (Refer to 23 - BODY/DOOR -
FRONT/LOCK CYLINDER - INSTALLATION). Refer
to the appropriate wiring information. The wiringinformation includes wiring diagrams, proper wire
and connector repair procedures, further details on
wire harness routing and retention, as well as pin-
out and location views for the various wire harness
connectors, splices and grounds.
OPERATION
The driver cylinder lock switch is actuated by the
key lock cylinder when the key is inserted in the lock
cylinder and turned to the unlock position. The
driver cylinder lock switch maintains a path to
ground and changes voltages through an internal
resistor for the DDM when the driver door key lock
cylinder is in the lock or unlock position. The DDM
reads the switch status through an internal pull-up,
then sends the proper switch status messages to
other electronic modules over the Programmable
Communications Interface (PCI) data bus network.
The driver cylinder lock switch unlock status mes-
sage is used by the BCM as an input for Vehicle
Theft Security System (VTSS) operation and interior
lighting.
POWER LOCK MOTOR
DESCRIPTION
Power operated front door, rear door, and liftgate
locking mechanisms are standard equipment on this
model. The lock mechanisms are actuated by a
reversible electric motor mounted within each door
and the liftgate. The power lock motors for the doors
are integral to the door latch units. The liftgate
power lock motor is a separate unit secured to the
latch brainplate near the center of the liftgate and
operates the liftgate latch lock mechanism through a
connecting linkage rod.
The power lock motors for the four doors cannot be
adjusted or repaired and, if faulty or damaged, the
entire door latch unit must be replaced. The liftgate
power lock motor cannot be adjusted or repaired and,
if faulty or damaged, the entire liftgate latch actua-
tor (brainplate) unit must be replaced.
OPERATION
The driver side front door power lock motor is con-
trolled by the Driver Door Module (DDM). The
remaining power door lock motors and the liftgate
power lock motor are controlled by the Passenger
Door Module (PDM). A positive and negative battery
connection to the two motor terminals will cause the
power lock motor plunger to move in one direction.
Reversing the current through these same two con-
nections will cause the power lock motor plunger to
move in the opposite direction.

DIAGNOSIS AND TESTING - POWER LOCK
MOTOR
Remember, the Driver Door Module (DDM) cir-
cuitry controls the output to the driver side front
door power lock motor. The Passenger Door Module
(PDM) circuitry controls the output to the power lock
motors for the remaining doors and the liftgate.
Refer to the appropriate wiring information. The wir-
ing 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.
(1) Check each power lock motor for correct opera-
tion while moving the power lock switch to both the
Lock and Unlock positions. If all of the power lock
motors are inoperative, go to Step 2. If one power
lock motor is inoperative, go to Step 3.
(2) If all of the power lock motors except the driver
side front door are inoperative, the problem may be
caused by one shorted motor. Disconnecting a shorted
power lock motor from the power lock circuit will
allow the good power lock motors to operate. Discon-
nect the wire harness connector from each PDM-con-
trolled power lock motor, one at a time, and recheck
both the lock and unlock functions by operating the
power lock switch. If all of the PDM-controlled power
lock motors are still inoperative after the above test,
check for a short or open circuit between the power
lock motors and the PDM. If disconnecting one power
lock motor causes the other motors to become func-
tional, go to Step 3 to test the power lock motor that
was last disconnected.
(3) Once it is determined which power lock motor
is inoperative, that motor can be tested as follows.
Disconnect the door or liftgate wire harness connec-
tor from the inoperative power lock motor. Apply 12
volts to the lock and unlock driver circuit cavities of
the power lock motor connector to check its operation
in one direction. Reverse the polarity to check the
motor operation in the opposite direction. If OK,
repair the shorted or open circuits between the lock
motor and the DDM or PDM as required. If not OK,
replace the faulty power lock motor.
POWER LOCK SWITCH
DESCRIPTION
The power lock motors are controlled by a two-way
momentary switch mounted on the trim panel of each
front door. Each power lock switch is illuminated by
a Light-Emitting Diode (LED) that is integral to the
switch paddle.
The driver side front door power lock switch is
integral to the Driver Door Module (DDM), and the
passenger side front door power lock switch is inte-
gral to the Passenger Door Module (PDM). The
power lock switches and their lamps cannot be
adjusted or repaired and, if faulty or damaged, the
entire DDM or PDM unit must be replaced. (Refer to
8 - ELECTRICAL/ELECTRONIC CONTROL MOD-
ULES/DOOR MODULE - DESCRIPTION).
OPERATION
The front door power lock switches provide a lock
and unlock signal to the door module circuitry. The
Driver Door Module (DDM) circuitry controls the out-
put to the driver side front door power lock motor,
while the Passenger Door Module (PDM) circuitry
controls the output to the passenger side front door,
both rear door and the liftgate power lock motors.
When the DDM-integrated power lock switch is
actuated, the DDM circuitry sends control outputs to
the driver side front door power lock motor and sends
a message to the PDM over the Programmable Com-
munications Interface (PCI) data bus to control the
output to the passenger side front door, both rear
door and the liftgate power lock motors. When the
PDM-integrated power lock switch is actuated, the
PDM circuitry sends control outputs to the passenger
side front door, both rear door and the liftgate power
lock motors and sends a message to the DDM over
the Programmable Communications Interface (PCI)
data bus to control the output to the driver side front
door power lock motor.
Each power lock switch is illuminated by a Light-
Emitting Diode (LED) when the ignition switch is
turned to the On position. See the owner's manual in
the vehicle glove box for more information on the fea-
tures, use and operation of the power lock switches.

OPERATION
The Driver Door Module (DDM) and the Passenger
Door Module (PDM) each contain the power mirror
control logic for the mirror on its respective door. The
DDM also houses the power mirror switch. Each door
module controls the positioning of its respective out-
side mirror through hard wired outputs to that mir-
ror. When the power mirror switch on the DDM is
used to position the passenger side outside mirror,
the DDM sends mirror positioning messages to the
PDM over the Programmable Communications Inter-
face (PCI) data bus. The PDM responds to these mes-
sages by sending control outputs to move the
passenger side mirror accordingly.
Both the PDM and DDM respond to the defogger
switch status messages sent by the Body Control
Module (BCM) over the PCI data bus to control the
electric heater grids of their respective mirrors.
(Refer to 8 - ELECTRICAL/HEATED MIRRORS -
DESCRIPTION) for more information on this fea-
ture.
On models equipped with the optional memory sys-
tem, each door module also receives a hard wired
input from the two power mirror motor position
potentiometers that are integral to each power mir-
ror. Each door module then stores the Driver 1 and
Driver 2 mirror position information for its respective
mirror. When the DDM receives a Driver 1 or Driver
2 memory recall message from the memory switch on
the driver side front door trim panel or from the
Remote Keyless Entry (RKE) receiver in the PDM,
the DDM positions the driver side mirror and sends
a memory recall message back to the PDM over the
PCI data bus to position the passenger side mirror.
See the owner's manual in the vehicle glove box for
more information on the features, use and operation
of the power mirror system.
DIAGNOSIS AND TESTING - POWER MIRRORS
Following are tests that will help to diagnose the
hard wired components and circuits of the power mir-
ror system. However, these tests may not prove con-
clusive in the diagnosis of this system. In order toobtain conclusive testing of the power mirror system,
the Programmable Communications Interface (PCI)
data bus network and all of the electronic modules
that provide inputs to, or receive outputs from the
power mirror system components must be checked.
The most reliable, efficient, and accurate means to
diagnose the power mirror system requires the use of
a DRB scan tool and the proper Diagnostic Proce-
dures manual. The DRB scan tool can provide confir-
mation that the PCI data bus is functional, that all
of the electronic modules are sending and receiving
the proper messages on the PCI data bus, that the
power mirror motors are being sent the proper hard
wired outputs, and that the mirror position potenti-
ometers are returning the proper outputs to the door
modules for them to perform their power mirror sys-
tem functions.
AUTOMATIC DAY/NIGHT
MIRROR
DESCRIPTION
DESCRIPTION - REAR VIEW MIRROR
An automatic day/night mirror system is an avail-
able factory-installed option on this model. The auto-
matic dimming inside day/night rear view mirror
system is a completely self-contained unit that
replaces the standard equipment inside rear view
mirror. This system will automatically change the
reflectance of the inside rear view mirror to protect
the driver from the unwanted headlight glare of
trailing vehicles while driving at night. The auto-
matic day/night inside mirror receives ignition
switched battery current through a fuse in the junc-
tion block, and will only operate when the ignition
switch is in the On position.
Vehicles equipped with the automatic day/night
mirror system are also available with an optional fac-
tory-installed automatic dimming outside rear view
mirror for the driver side of the vehicle. (Refer to 8 -
ELECTRICAL/POWER MIRRORS/SIDEVIEW MIR-
ROR - DESCRIPTION) for more information on this
option.
The automatic day/night mirror sensitivity cannot
be repaired or adjusted. If any component of this unit
is faulty or damaged, the entire automatic day/night
inside rear view mirror unit must be replaced. Refer
to the appropriate wiring information. The wiring
information includes wiring diagrams, proper wire
and connector repair procedures, details of wire har-
ness routing and retention, connector pin-out infor-
mation and location views for the various wire
harness connectors, splices and grounds.
8N - 12 POWER MIRRORSWJ
POWER MIRRORS (Continued)

DESCRIPTION - OUTSIDE REAR VIEW MIRROR
An automatic dimming outside rear view mirror is
an available factory-installed option for the driver
side of the vehicle, if the vehicle is also equipped
with the automatic day/night inside rear view mirror.
The automatic dimming outside mirror is completely
controlled by the circuitry of the automatic day/night
inside rear view mirror. The automatic dimming out-
side mirror will automatically change the reflectance
of the driver side outside rear view mirror to protect
the driver from the unwanted headlight glare of
trailing vehicles while driving at night. The auto-
matic dimming outside mirror will only operate when
the ignition switch is in the On position.
The automatic dimming outside mirror sensitivity
cannot be repaired or adjusted. If any component of
this unit is faulty or damaged, the entire automatic
dimming outside mirror unit must be replaced. (Refer
to 8 - ELECTRICAL/POWER MIRRORS/SIDEVIEW
MIRROR - DIAGNOSIS AND TESTING). Refer to
the appropriate wiring information. The wiring infor-
mation 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 con-
nectors, splices and grounds.
OPERATION
OPERATION - REAR VIEW MIRROR
The automatic day/night mirror switch allows the
driver a manual control of whether the automatic
dimming feature is operational. This switch is a
momentary rocker-type switch located on the lower
rear-facing surface of the mirror housing. When Auto
is selected, a Light-Emitting Diode (LED) on the mir-
ror housing just to the right of the switch illuminates
to indicate that automatic day/night mirror is turned
on. When Off is selected, the LED is turned off. The
mirror also senses the backup lamp circuit, and will
automatically disable its self-dimming feature when-
ever the transmission gear selector is in the Reverse
position.
A thin layer of electrochromatic material between
two pieces of conductive glass make up the face of
the mirror. Two photocell sensors are used to monitor
light levels and adjust the reflectance of the mirror.
The ambient photocell sensor faces forward, to detect
the outside light levels. The headlamp sensor is
located on the mirror housing just to the left of the
switch and facing rearward, to detect the light level
received at the rear window side of the mirror. When
the difference between the two light levels becomes
too great (the light level received at the rear of themirror is much higher than that at the front of the
mirror), the mirror begins to darken.
On models with an optional driver side automatic
dimming outside mirror, the signal to control the
dimming of that mirror is generated by the auto-
matic day/night inside rear view mirror circuitry.
That signal is then delivered to the driver side out-
side rear view mirror on a hard wired circuit.
See the owner's manual in the vehicle glove box for
more information on the features, use and operation
of the automatic day/night mirror system.
OPERATION - OUTSIDE REAR VIEW MIRROR
The automatic dimming outside mirror is operated
by the same controls and circuitry as the automatic
day/night mirror. When the automatic day/night mir-
ror is turned on or off, the automatic dimming out-
side mirror is likewise turned on or off. Like in the
automatic day/night mirror, a thin layer of electro-
chromatic material between two pieces of conductive
glass make up the face of the automatic dimming
outside mirror. However, the signal to control the
dimming of the outside mirror is generated by the
automatic day/night inside rear view mirror circuitry.
See the owner's manual in the vehicle glove box for
more information on the features, use and operation
of the automatic dimming outside mirror.
