For proper diagnosis of these electronic modules or of
the PCI data bus network, the use of a DRBIII
t
scan
tool and the appropriate diagnostic information are
required.
CHILD PROTECTION LOCKS
To provide a safer environment for children riding
in the rear seat, the rear doors have the “child pro-
tection” door lock system.
The child protection locks are on the rear doors
only. The lock, when engaged, will disable the inside
door handle from opening the door. The lock is part
of the latch/lock assembly.
DOOR LOCK INHIBIT
With the key in the ignition switch and the driver
door open, the Remote Keyless Entry (RKE) module
will ignore the command to lock the power door locks
using the interior door lock switches. Once the key is
removed, or the drivers door is closed, the RKE mod-
ule will allow the power locks to lock using the door
lock switch.
REMOTE KEYLESS ENTRY
The remote keyless entry system allows locking
and unlocking of the vehicle door(s) liftgate, panic
alarm and arming or disarming of the vehicle theft
security system (if equipped), using the hand held
radio frequency (RF) transmitter.
The receiver may receive signals from up to four
transmitters. Each transmitter has its own code, and
the code is programmed and stored into RKE module
memory. If a transmitter is replaced or additional
transmitters are added, the codes for all units have
to be reprogrammed into the RKE module memory. If
a receiver module is replaced, the transmitter codes
must be stored in the new receiver memory (by per-
forming the steps for programming transmitters).
The RKE module is capable of retaining all transmit-
ter codes when power is removed from the module.
OPERATION
POWER LOCKS
All doors can be locked or unlocked mechanically
and independently with their respective locking
knobs. The front doors can also be unlocked by actu-
ation of the inside remote door handle.
CENTRAL LOCKING/UNLOCKING (IF EQUIPPED)
The door locks can be locked or unlocked electrically
via the exterior door key cylinders to provide the central
locking/unlocking feature. The central locking/unlocking
feature incorporates a customer programmable

feature which operates in the follow-
ing manner: When enabled, the first turn of the key cyl-
inder to the UNLOCK position (toward the front of the
vehicle) will mechanically unlock the door whose key
cylinder is being turned. A second turn of the key cylin-
der to the UNLOCK position (within five seconds of the
first turn) will cause all vehicle doors and liftgate to
unlock electrically. When this feature is disabled, all
vehicle doors and liftgate will be unlocked electrically
upon the first turn of a key cylinder to the UNLOCK
position. The vehicle is locked electrically by turning the
key cylinder to the LOCK position once, regardless of
the state of the double activation unlock feature.
REMOTE KEYLESS ENTRY
The transmitter has three buttons for operation:
LOCK, UNLOCK and PANIC.
•
Pressing the UNLOCK button will unlock the
driver’s door, flash the park lamps twice and enable
illuminated entry. Pressing and releasing the button
once will unlock the drivers door. Pressing and
releasing the button two tomes within a five second
interval will unlock all doors.
•
Pressing the LOCK button will cause the horn
to sound a short chirp (if enabled) and flash the park
lamps to notify that the all door lock signal was
received and set. Illuminated entry is cancelled and
the interior lamps are faded to off.
•
Pressing the PANIC button will cause the panic
alarm to sound for three minutes, until the PANIC
button is pressed a second time, or the vehicle
reaches a speed of 25.7 Km/h (15 mph). The receiver
is capable of retaining a Vehicle Access Code (VAC)
even when power is removed. Each Remote Keyless
Entry (RKE) module must have at least one and no
more than four transmitter.
ROLLING DOOR LOCKS
When the rolling door lock system is enabled, the
RKE module will automatically lock all the vehicle
doors and liftgate when all of the following conditions
are met:
•
All doors are closed
•
The vehicle speed exceeds 25.7 Km/h (15 +/- 1
mph).
•
The throttle position sensor tip-in is greater
than 10 +/- 2 degrees.
The RKE module will automatically re-lock all
doors if the above conditions are met and if any of
the doors become ajar and then closed again.
The enabling/disabling of the rolling door lock fea-
ture is customer programmable, as well as program-
mable with the DRB lll
t
scan tool.
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.
