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 can be locked or unlocked by using the key cyl-
inder.
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
If the door lock switch is actuated continuously for
more than five seconds the instrument cluster will
turn the output driver OFF (the instrument cluster
would consider the switch stuck). Each lock motor is
protected with a Positive Temperature Coefficient
device that prevents motor burn out.
REMOTE KEYLESS ENTRY
²LOCK: Pressing the LOCK button locks all
doors, sounds horn (chirp) once if enabled, flashes the
park lamps once if enabled, and arms the Vehicle
Theft Security System (VTSS), if enabled. The chirp
verifies that the RKE module has sent a message to
the instrument cluster 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 first if enabled, flashes
the park lamps twice if enabled, activates the illumi-
nated entry system, and disarms the Vehicle Theft
Security System (VTSS), if equipped. Pressing the
UNLOCK button twice within five seconds will
unlock all doors, if driver's door first is enabled.
²PANIC: Pressing the PANIC button sounds the
horns at half second intervals, flashes the exteriorlamps, 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 vehicle speed
exceeds 25.7 Km/h (15 mph) will cancel the panic
event.
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 most reliable, efficient, and accurate
means to diagnose the power lock system
requires the use of a DRBIIItscan tool and the
proper Diagnostic Procedures manual. The
DRBIIItscan tool can provide confirmation
that the PCI data bus is functional, that all of
the electronic modules are sending and receiv-
ing the proper messages on the PCI data bus,
and that the power lock motors are being sent
the proper hard wired outputs by the relays for
them to perform their power lock system func-
tions.
Following are tests that will help to diagnose the
hard wired components and circuits of the power lock
system. However, these tests may not prove conclu-
sive in the diagnosis of this system. In order to
obtain conclusive testing of the power lock 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 lock system components must be checked.
The instrument cluster will set Diagnostic Trouble
Codes (DTC) for the power lock system.
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 DIAGNOSIS
As a preliminary diagnosis for the power lock sys-
tem, note the system operation while you actuate
both the Lock and Unlock functions with the power
lock switches and with the Remote Keyless Entry
(RKE) transmitter. Then, proceed as follows:
²If the entire power lock system fails to function
with either the power lock switches or the RKE
transmitter, check the fused B(+) fuse in the Inte-
grated Power Module (IPM).
²If the power lock system functions with both
power lock switches, but not with the RKE transmit-
ter, proceed to diagnosis of the Remote Keyless Entry
(RKE) system. (Refer to 8 - ELECTRICAL/POWER
LOCKS/KEYLESS ENTRY TRANSMITTER - DIAG-
DRPOWER LOCKS 8N - 3
POWER LOCKS (Continued)

NOSIS AND TESTING) or (Refer to 8 - ELECTRI-
CAL/POWER LOCKS/REMOTE KEYLESS ENTRY
MODULE - DIAGNOSIS AND TESTING).
²If the power lock system functions with the RKE
transmitter, but not with one or both power lock
switches, proceed to diagnosis of the door lock
switches. (Refer to 8 - ELECTRICAL/POWER
LOCKS/POWER LOCK SWITCH - DIAGNOSIS AND
TESTING).
²If the driver side power lock switch operates
only the driver side front door power lock motor, but
all other power lock motors operate with the passen-
ger side power lock switch or the RKE transmitter,
use a DRBIIItscan tool and the appropriate diagnos-
tic information to diagnose the Programmable Com-
munications Interface (PCI) data bus.
²If only one power lock motor fails to operate
with both power lock switches and the RKE trans-
mitter, proceed to diagnosis of the power lock motor.
(Refer to 8 - ELECTRICAL/POWER LOCKS/POWER
LOCK MOTOR - DIAGNOSIS AND TESTING).
POWER LOCK SWITCH
DIAGNOSIS AND TESTING - POWER LOCK
SWITCH
The Light-Emitting Diode (LED) illumination lamp
of the power lock switch receives battery current
through a fuse in the Integrated Power Module (IPM)
on a fused ignition switch output (run) circuit. The
power lock switch on the driver side front door trim
panel is integral to the driver door module. (Refer to
8 - ELECTRICAL/POWER LOCKS/DOOR MODULE
- DIAGNOSIS AND TESTING). If the power lock
switch operates, but the LED is inoperative, check
for battery current at the switch with the ignition
switch in the On position. If OK, replace the faulty
switch. 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.
(1) Disconnect and isolate the battery negative
cable. Remove the power lock switch from the door
trim panel. Disconnect the door wire harness connec-
tor for the power lock switch from the switch connec-
tor receptacle.
(2) Test the power lock switch resistance. See the
Power Lock Switch Test chart to determine if the
resistance is correct for the switch in each switch
position (Fig. 1). If not OK, replace the faulty power
lock switch as required.
REMOVAL
The power lock switch on the driver side front door
trim panel is integral to the driver door module.
(Refer to 8 - ELECTRICAL/POWER LOCKS/DOOR
MODULE - REMOVAL).

DOOR LOCK MOTOR
DESCRIPTION
The lock mechanisms are actuated by a reversible
electric motor mounted within each door. The power
lock motors are integral to the door latch units.
The power lock motors cannot be adjusted or
repaired and, if faulty or damaged, the door latch
unit must be replaced.
OPERATION
The door lock motors are controlled by the instru-
ment cluster. A positive and negative battery connec-
tion to the two motor terminals will cause the motor
to move in one direction. Reversing the current will
cause the motor to move in the opposite direction.
DIAGNOSIS AND TESTING - DOOR LOCK
MOTOR
The most reliable, efficient, and accurate means to
diagnose the power lock system requires the use of a
DRBIIItscan tool and the proper Diagnostic Proce-
dures manual. The DRBIIItscan tool can provide
confirmation that the PCI data bus is functional, that
all of the electronic modules are sending and receiv-
ing the proper messages on the PCI data bus, and
that the power lock motors are being sent the proper
hard wired outputs by the door modules for them to
perform their power lock system functions.
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.
DRIVER DOOR MODULE
DESCRIPTION
A Driver Door Module (DDM) is used on all models
equipped with power locks, power windows, and
power mirrors. The DDM houses the following
switches:
²Power Lock Switch- The DDM includes a
two-way, momentary, resistor multiplexed switch to
control the power lock system.
²Power Mirror Selector Switch- A three-posi-
tion rocker switch in the DDM selects the right or
left power mirror for adjustment, or turns the power
mirror system Off.
²Power Mirror Adjustment Switches- Four
momentary, arrowhead shaped, directional switches
allow the driver to adjust the selected power mirror
in the Up, Down, Right, or Left directions.²Power Window Lockout Switch- A two-way,
latching, push-button switch in the DDM allows the
vehicle operator to lock out the power window
switches on each passenger door so that the passen-
ger door power windows may be operated only from
the master switches in the DDM.
²Power Window Switches- The DDM houses a
two-way, momentary power window switch for the
driver side front door. This switch also has a second
detent in the Down direction and internal circuitry to
provide an Auto-Down feature for the driver side
front door power window. In addition to the power
window switch for its own door, the DDM houses
individual master switches for each passenger door
power window.
The DDM also incorporates several green Light-
Emitting Diodes (LEDs) that illuminate the power
lock and power window switch paddles, and the
power mirror switch directional buttons to improve
switch visibility in dark ambient lighting conditions.
The DDM cannot be adjusted or repaired and, if
faulty or damaged, the entire DDM unit must be
replaced.
OPERATION
The Driver Door Module (DDM) combines a power
lock switch, a driver power window switch with an
Auto-down feature, master switches for each passen-
ger door power window, a power window lockout
switch, a power mirror selector switch, and four
power mirror adjustment switches in a single unit.
The switches in the DDM can be diagnosed using
conventional diagnostic tools and methods.
Power Lock Switch
The DDM power lock switch circuitry is connected
in series between ground and the driver door switch
mux input of the instrument cluster. Each power lock
switch position (Lock, Unlock, and Neutral) provides
a different resistance value to the instrument cluster
input, which allows the instrument cluster to sense
the switch position. Based upon the power lock
switch input, the instrument cluster controls the bat-
tery and ground feed outputs to the individual power
lock motors to lock or unlock the door latches. The
Light-Emitting Diode (LED) in the DDM power lock
switch is connected to battery current through the
power window circuit breaker in the Integrated
Power Module (IPM) on a fused ignition switch out-
put (run-acc) circuit so that the switch will be illumi-
nated whenever the ignition switch is in the On or
Accessory positions.
Power Window Switches
The DDM power window switch circuitry is con-
nected to battery current through a circuit breaker in
DRPOWER LOCKS 8N - 5

the Integrated Power Module (IPM) on a fused igni-
tion switch output (run-acc) circuit so that the power
windows will operate whenever the ignition switch is
in the On or Accessory positions. Each two-way,
momentary master passenger power window switch
in the DDM provides battery current and ground to
the individual power window switches on each pas-
senger door so that the power window switch controls
the battery current and ground feeds to its respective
power window motor. The DDM switch for the driver
side front door power window is labeled ªAutoº and
includes an auto-down feature. When this switch is
depressed to a second momentary detent position and
released, the driver door power window is automati-
cally operated through an internal circuit and relay
to its fully lowered position. The Auto-down event is
cancelled if the switch paddle is depressed a second
time in either the Up or Down direction. When the
two position window lockout switch in the DDM is
depressed and latched in the lockout position, the
battery current feed to each of the individual passen-
ger power window switches is interrupted so that the
passenger door power windows can only be operated
from the master switches in the DDM. The window
lockout switch also controls the battery current feed
for the LED in each passenger power window switch
so that the switch will not be illuminated when it is
locked out.
Power Mirror Switches
The DDM power mirror switch circuitry is con-
nected to battery current through a fuse in the IPM
on a fused B(+) circuit so that the power mirrors
remain operational regardless of the ignition switch
position. A rocker type selector switch has three posi-
tions, one to select the right mirror, one to select the
left mirror, and a neutral Off position. After the right
or left mirror is selected, one of four directional but-
tons is depressed to move the selected mirror Up,
Down, Right or Left. The DDM power mirror switch
circuitry controls the battery current and ground
feeds to each of the four (two in each mirror head)
power mirror motors. The Light-Emitting Diode
(LED) in the DDM power mirror switch is connected
to battery current through the power window circuit
breaker in the IPM on a fused ignition switch output
(run-acc) circuit so that the switch directional but-
tons will be illuminated whenever the ignition switch
is in the On or Accessory positions.DIAGNOSIS AND TESTING - DRIVER DOOR
MODULE
The Light-Emitting Diode (LED) illumination
lamps for all of the Driver Door Module (DDM)
power window, power lock, and power mirror
switches receive battery current through the power
window circuit breaker in the Integrated Power Mod-
ule (IPM). If all of the LEDs are inoperative in the
DDM, be certain to diagnose the power window sys-
tem before replacing the switch unit. (Refer to 8 -
ELECTRICAL/POWER WINDOWS - DIAGNOSIS
AND TESTING). If only one LED in the DDM is
inoperative, replace the faulty DDM. If the driver
side front door power window operates in a normal
manner, but the Auto-Down feature is inoperative,
replace the faulty DDM. Refer to the appropriate wir-
ing information. The wiring information includes wir-
ing 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) Disconnect and isolate the battery negative
cable. Remove the DDM from the door trim panel.
Disconnect the door wire harness connectors for the
DDM from the DDM connector receptacles.
(2) Test the DDM switch continuity. See the Driver
Door Module Switch Tests chart to determine if the
continuity is correct for the suspect switches in each
switch position (Fig. 2) and/or (Fig. 3). If not OK,
replace the faulty DDM as required.

DESCRIPTION
AUTOMATIC DAY/NIGHT MIRROR
The automatic day/night mirror system is able to
automatically change the reflectance of the inside
rear view mirror in order to reduce the glare of head-
lamps approaching the vehicle from the rear. The
automatic day/night rear view mirror receives bat-
tery current through a fuse in the Integrated Power
Module (IPM) only when the ignition switch is in the
On position.
OUTSIDE REAR VIEW MIRROR
The power operated outside rear view mirrors
allow the driver to adjust both outside mirrors elec-
trically from the driver side front seat position by
operating a switch on the driver side front door trim
panel. The power mirrors receive a non-switched bat-
tery feed through a fuse in the Integrated Power
Module (IPM) so that the system will remain opera-
tional, regardless of the ignition switch position.
OPERATION
AUTOMATIC DAY/NIGHT MIRROR
A switch located on the bottom of the automatic
day/night mirror housing allows the vehicle operator
to select whether the automatic dimming feature is
operational. When the automatic day/night mirror is
turned on, the mirror switch is lighted by an integral
Light-Emitting Diode (LED). The mirror will auto-
matically disable its self-dimming feature whenever
the vehicle is being driven in reverse.Refer to the owner's manual for more information
on the features, use and operation of the automatic
day/night mirror system.
OUTSIDE REAR VIEW MIRROR
The heated mirrors include an electric heating grid
behind the mirror glass in each outside mirror, which
can clear the mirror glass of ice, snow, or fog. (Refer
to 8 - ELECTRICAL/HEATED MIRRORS -
DESCRIPTION) for more information.
