DESCRIPTION AND OPERATION
POWER DOOR LOCK SYSTEM
DESCRIPTION
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 (BCM) 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 all locks can be remotely locked or unlocked with
the Remote Keyless Entry (RKE) transmitter. All
doors can be locked/unlocked from the front doors via
the Central Locking System. 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.
OPERATION
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 DRBIIIt scan tool is used to enable/disable the
automatic door lock system. Refer to the proper Body
Diagnostic Procedures Manual. They are also cus-
tomer programmable. Refer to Owners Manual for
customer programming procedures.
