GENERAL INFORMATION
INTRODUCTION
Power door locks are optional factory-installed
equipment on this model. The Remote Keyless Entry
(RKE) system, illuminated entry system and power
windows are included on vehicles equipped with the
power door lock option. Refer to 8W-61 - Power Door
Locks in Group 8W - Wiring Diagrams for complete
circuit descriptions and diagrams.
POWER LOCK SYSTEM
The power lock system allows all four doors and
the liftgate to be locked or unlocked electrically by
operating the switch on either front door trim panel.
The power lock system operates on non-switched bat-
tery current supplied through a fuse in the junction
block so that the system remains functional, regard-
less of the ignition switch position.
The power lock system includes the power lock
switches on each front door trim panel, and the
power lock motors inside each door and the liftgate.
The power lock control circuitry and the power lock
and unlock relays are integral to the high-line ver-
sion of the Central Timer Module (CTM), which is
mounted under the instrument panel.
Following are general descriptions of the major
components in the power lock system. Refer to the
owner's manual in the vehicle glove box for more

information on the features, use and operation of the
power lock system.
REMOTE KEYLESS ENTRY SYSTEM
The Remote Keyless Entry (RKE) system is a radio
frequency system that allows the use of a remote bat-
tery-powered radio transmitter to control the power
lock system. On vehicles with the RKE option, the
power locks can be operated by depressing the Lock
or Unlock buttons of the RKE transmitter. If the
vehicle is so equipped, the RKE transmitter also
arms and disarms the factory-installed vehicle theft
alarm. Refer to Group 8Q - Vehicle Theft/Security
Systems for more information on the optional vehicle
theft alarm.
The RKE system includes an illuminated entry fea-
ture, which turns on the courtesy lamps for a timed
interval (about thirty seconds), when the power door
locks are unlocked using the RKE transmitter. The
RKE system for this vehicle also features a program-
mable horn chirp, a programmable driver door
unlock, a programmable rolling door lock, and a
panic feature.
The programmable horn chirp feature allows the
enabling or disabling of the horn chirp request that
the RKE receiver issues as an audible indication that
a valid Lock signal has been received from the RKE
transmitter. The programmable driver door unlock
feature allows one press of the RKE transmitter
