GENERAL INFORMATION

Both front doors and sliding side door, when elec-

trically equipped, can be locked or unlocked electri-
cally by operating the switch on a front door panel.

All doors can be locked or unlocked mechanically

with the locking knob.

Both front doors and sliding door can be locked or

unlocked mechanically from the outside with the key
or electrically as described above. Both front doors
can also be unlocked by actuation of their respective
inside remote door handle.

The lift gate release consists of a latch with inter-

nal solenoid, A relay and push button switch. The so-
lenoid is energized only when the push button is
depressed.

DOOR LOCK INHIBIT

When the key is in the ignition switch in the ON or

OFF position with the driver’s door open, the body
control module will ignore the command to lock the
power door locks. Once the key is removed, or the
driver’s door is closed, the body control module will
allow the power door locks to lock.

REMOTE KEYLESS ENTRY SYSTEM (RKE)

The system allows locking and unlocking of vehicle

doors and lift gate by remote control using a hand
held radio transmitter. The ignition switch must be
OFF before the lift gate can be unlocked with the
transmitter.

The receiver may receive signals from two trans-

mitters. Each transmitter has its own code, and the
code has been stored in memory. If the transmitter is
replaced or a second transmitter is add, the code on
both units have to be placed in memory.

POWER DOOR LOCKS

When vehicle is equipped with power door locks,

the system includes an automatic door locking fea-
ture. Which is actuated through the vehicle’s body
control module.

The vehicle is built with the system disabled.
When the system is disabled the door locks will

work by use of the door lock switches only. When this
system is enabled the automatic door locks will work
automatically.

The body control module controls the power locks

when the door lock switch is activated. If the door
lock switch is pressed for longer than eight consecu-
tive seconds, the body control module will de-energize
the door lock relay. Also, the body control module will
automatically lock all doors when all of the condi-
tions 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 automatic door lock can be enable/disable.
The body control module will automatically re-lock

all doors if the above conditions are met and if any of
the doors become ajar. The body control module does
not control the door unlock function. The switch is
wired directly to the unlock relay.

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.

The sliding door can be locked or unlocked electri-

cally when the door is closed. The sliding door can
also be locked electrically when the door is open as
follows: By activating the power lock switch to the
lock position while the sliding door is open and the
key is not in the ignition switch. The front doors will
lock and send a signal to the body control module to

relock all doors upon the sliding door closing. Activat-
ing the power lock switch to the unlock position be-
fore the sliding door is closed will cancel the lock
request.

AUTOMATIC DOOR LOCKS

The vehicle comes with two options for automatic

door locks:
• Rolling automatic lock, enable approximately at 16
mph.
• No automatic lock, disable.

To change the automatic door lock selection, do the

following:

(1) Close all doors.
(2) Place the ignition key in the OFF position for

20 seconds or more.

(3) Turn ignition key to the run position and to the

OFF position without cranking the engine four times.
The malfunction lamp will come on each time the key
is in the run position.

(4) Press the power door lock button to lock the

doors. This procedure selects the next possible auto-
matic door lock option. If the present option is unde-
sirable, repeat to arrive at the desired option.

DOOR LOCK SYSTEM TEST

For complete testing of the automatic door lock sys-

tems, refer to the Body Diagnostic Procedures Man-
ual.

SWITCH VOLTAGE TEST

The following wiring test sequence determines

whether or not voltage is continuous through the
body harness to switch.

After removing switch from trim panel for testing

purposes, carefully separate multiple terminal block
on wiring harness from switch body. Connect one
lead of test light to terminal 3 and touch other test
light lead to ground (Fig. 1). If the test light comes
on, the wiring circuit between the battery and switch
is functional. If light does not come on, check 30 amp
circuit breaker or for a open circuit.

CIRCUIT BREAKER TEST

Find correct circuit breaker on fuse block. Pull out

slightly but be sure that circuit breaker terminals
still contact terminals in fuse block. Connect ground
wire of voltmeter to a good ground. With probe of
voltmeter positive wire, check both terminals of cir-
cuit breaker for 12 volts. If only one terminal checks
at 12 volts, circuit breaker is defective and must be
replaced. If neither terminal shows 12 volts, check
for open or shorted circuit to circuit breaker.

SWITCH TEST

For switch testing, remove the switch and bezel as-

sembly from its mounting location. Using an ohmme-

ter, refer to (Fig. 1) to determine if continuity is
correct in the Lock and Unlock switch positions. If
these results are not obtained, replace the switch.

CIRCUIT TEST SLIDING DOOR

Connect one lead of a test light to the upper con-

tact on the B— pillar and the other lead to the lower
contact. If the test light comes on when the lock
switch is depressed, the wiring circuit to the contacts
is good. If the test light does not come on:
• Check fuse

• Check connectors at the right side cowl

• Check for a broken wire

The sliding door partially open, connect jumper

wires from contacts on door to contacts on B—pillar.
Connecting these contacts should lock or unlock door
when switch is depressed.

If lock and unlock occurs, the fault is at the door

and pillar switch contacts. Check for proper shim at
door contact plate. If lock and unlock does not occur,
remove door trim panel and check for voltage at mo-
tor connector.

ELECTRIC MOTOR TEST

Make certain battery is in normal condition before

circuits are tested.

To determine which motor is faulty, check each in-

dividual door for electrical lock and unlock or discon-
nect the motor connectors one at a time, while
operating the door lock switch. In the event that
none of the motors work, the problem may be caused
by a shorted motor, a relay or a bad switch. Discon-
necting the 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 (Figs. 2 and 3). To unlock the door reverse the
wire connections at the motor pin terminals. If these
results are NOT obtained, replace the motor.

LIFT GATE OPERATION

The lift gate is controlled by a push button switch

in the steering column cover. The switch control a re-
lay in the relay bank. The body control module pro-
vides the ground for this relay only when the vehicle
is not moving. Automatic Transaxle must be in park
or neutral.

TEST

(1) Confirm solenoid lead wire is connected and 10

volts or more are available at solenoid (Fig. 4).

(2) Provide proper ground through latch mounting

screws.

(3) Remove latch and examine plunger, to insure it

latches with a moderate slam. Should latch fail to
lock, replace latch assembly.

With ignition switch in ON or ACCESSORY posi-

tion, push lift gate switch to a ensure proper opera-
tion.
