GENERAL INFORMATION
INTRODUCTION
Power locks are optional factory-installed equip-
ment on this model. The power window system and
the power mirror system are included on vehicles
equipped with the power lock option. The Remote
Keyless Entry (RKE) system is an additional option
available on vehicles equipped with the power lock
option. Refer to 8W-61 - Power Door Locks in Group
8W - Wiring Diagrams for complete circuit descrip-
tions and diagrams.
NOTE: This group covers both Left-Hand Drive
(LHD) and Right-Hand Drive (RHD) versions of this
model. Whenever required and feasible, the RHD
versions of affected vehicle components have been
constructed as mirror-image of the LHD versions.
While most of the illustrations used in this group
represent only the LHD version, the diagnostic and
service
procedures
outlined
can
generally
be
applied to either version. Exceptions to this rule
have been clearly identified as LHD or RHD, if a
special illustration or procedure is required.
POWER LOCK SYSTEM
The power lock system allows all of the doors and
the liftgate to be locked or unlocked electrically by
operating the switch on either front door trim panel.
This system operates with battery power supplied
through a fuse in the junction block, independent of
the ignition switch.
The power lock system includes a lock inhibit fea-
ture, which prevents the doors from being locked by
the power lock system if the driver door is open with
the key in the ignition switch or with the headlamp
switch in the On position. However, the lock inhibit
feature will not prevent manual locking of the vehicle
using the manual lock buttons or the key cylinders.
The power lock system includes the front door
power lock switches integral to the driver and pas-
senger door modules, and the power lock motors
mounted in each door and the liftgate. The power
lock control circuitry and the power lock and unlock
relays are integral to the Passenger Door Module
(PDM).
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. The RKE
system includes an illuminated entry feature, which
turns on the courtesy lamps for a timed interval
