GENERAL INFORMATION
INTRODUCTION
All doors can be locked or unlocked electrically by
operating the switch on either front door panels.
When the door lock switch is activated the Body Con-
trol Module actuates the door lock relay.
All doors can be locked or unlocked mechanically
and independently with their respective locking
knobs.
The right and left front door can be locked or
unlocked mechanically from the outside with the key
or remotely with the Remote Keyless Entry (RKE)
transmitter. The front doors can also be unlocked by
actuation of the inside remote door handle.
The deck lid can be unlatched by either depressing
the push switch from inside the car, manually by key
from outside or by depressing the remote keyless
entry deck lid release button two times. This feature
is customer programmable. The customer has a
choice of one or two button presses for deck lid open-
ing. The vehicle is shipped in the button pressed
twice mode.
DESCRIPTION AND OPERATION
POWER DOOR LOCKS
The Body Control Module (BCM) actuates the
power door lock relays when a door lock switch is
activated. If the door lock switch is pressed for longer
than eight consecutive seconds, the BCM will de-en-
ergize the door lock relay.
The system includes an Automatic Door Locking
feature. The vehicle is shipped with the system
enabled. When the system is disabled the door locks
will work by use of the door lock switches and the
Remote Keyless Entry System only. When the Auto-
matic Door Lock System is enabled the BCM will
automatically lock all the doors when all of the con-
ditions below are met:
• All doors are closed
• The vehicle speed exceeds 15 6 1 mph
• The throttle position sensor tip-in is greater
than 10
6 2 degrees
The scan tool (DRB) is used to enable/disable the
automatic door lock system. Refer to the proper Body
Diagnostic Procedures Manual for the procedure.
They are also customer programmable. Refer to own-
ers manual for customer programming procedures.

The
Body
Control
Module
will
automatically
re-lock all doors if the above conditions are met and
if any of the doors become ajar and then closes again.
The power lock motors are also equipped with a
thermal protection system which prevents the motors
from burning out. The motors may chatter if they are
continuously activated.
CHILD PROTECTION LOCK
The child protection locks are on the rear doors
only. The lock when engage, will disable the inside
door handle from opening the door. The lock is part
of the latch/lock assembly. The lock is engaged by
moving a lever that is located on the rearward inside
edge of the door.
DOOR LOCK INHIBIT
With the key in the ignition switch and the driver’s
door open, the Body Control Module (BCM) will
ignore the command to lock the power door locks.
Once the key is removed, or the driver’s door is
closed, the BCM will allow the power door locks to
lock.
KEYLESS ENTRY SYSTEM
The system allows locking and unlocking of vehicle
door(s) and deck lid by remote control using a hand
held radio frequency (RF) transmitter. The ignition
switch must be OFF before the trunk lid can be
unlatched with the transmitter.
The receiver may receive signals from four trans-
mitters (vehicles are shipped with two). Each trans-
mitter has its own code and the code has been stored
in memory. If the transmitter is replaced or other
transmitters are added, the code for each unit must
be learned.
DIAGNOSIS AND TESTING
AUTOMATIC DOOR LOCK SYSTEM
For complete testing of the automatic door lock
systems, refer to the proper Body Diagnostics Man-
ual.
DECK LID RELEASE
For vehicles equipped with electric trunk lid
release.
(1) Confirm motor lead wire is connected and 10
volts or more are available at solenoid.
(2) Provide proper ground through latch mounting
screws.
(3) Remove latch and examine plunger. Plunger
should spring back when pressed.
(4) Insure that solenoid plunger travel is adequate
approximately 16 mm (5/8 inch).
DOOR LOCK MOTOR
Make certain battery is in normal condition before
circuits are tested.
To determine which motor is faulty, check each
individual door for electrical lock and unlock or dis-
connect the motor connectors one at a time, while
operating the door lock switch. In the event that
none of the motors work, the problem maybe caused
by a shorted motor, a bad switch or a bad relay. Dis-
connecting a defective motor will allow the others to
work.
To test an individual door lock motor, disconnect
the electrical connector from the motor. To lock the
door, connect a 12 volt power source to the positive
pin of the lock motor and a ground wire to the other
pin (Fig. 1). To unlock the door reverse the wire con-
nections at the motor pin terminals. If these results
are NOT obtained, replace the motor.
DOOR LOCK SWITCH
Remove the switch from its mounting location.
Using an ohmmeter, refer to Door Lock Switch Con-
tinuity Test table to determine if continuity is correct
in the Lock and Unlock switch positions. If these
results are not obtained, replace the switch.

DESCRIPTION AND OPERATION (Continued)
DOOR LOCK SYSTEM
For complete testing of the automatic door lock
systems, refer to the proper Body Diagnostic Proce-
dures Manual.
VOLTAGE
The following wiring test sequence determines
whether or not voltage is continuous through the
body harness to switch.
(1) Remove left side switch from door trim panel.
(2) Carefully separate multiple terminal block on
wiring harness from switch body.
(3) Connect one lead of test light to a ground ter-
minal:
• Touch other test light lead to battery feed B+
terminal.
• If test light comes on, the wiring circuit between
the battery and switch is functional.
• If test light does not come on, check fuse 13 in
the Junction Block for a blown fuse. Refer to Group
8W, Wiring Diagrams for circuit information.
REMOVAL AND INSTALLATION
DECK LID RELEASE MOTOR
