Power Door Locks (cont'd)
- How the Circuit Works
Keyless Entry System
The keyless door locks combine the power door
locks with a remote keyJob transmitter. The keyless
receiver unit is part of the radio. The keyless
receiver unit receives direct inputs f rom the ignition
key switch, the passenger door switches, and an
indirect input trom the driver's door switch through
the integrated control unit.
Power Door Locks (With or Wlthout Keyless)
The power door lock system is made up of the
oower door lock control unit. driver's door lock
switch, and individual door lock actuators. The
power door locks are controlled by the driver's door
lock switch and the driver's door lock actuator
switch.
Transmitter (With Keyless Entry)
The transmitter sends coded radio wave signals to
the keyless receiver unit when one ot its buttons is
pressed. Each transmitter has a unique code that
must be 'laught" to the keyless receiver unit before
it can operate the door locks or any other lunction.
Up to 4 transmitters can be programmed to operate
the keyless door locks.
Door Locking (With or without Keyless Entry)
When you push the driver's door lock switch to the
lock position, ground is applied to the GBN/IVHT
wire to the oower door lock control unit. The control
unit then applies battery voltage to the WHT/RED
wire and ground to the YEURED wire. The
passenger door lock actuators then activate to lock
the corresponding door locks.
When you lock the driver's door with the key or door
lock knob, it is mechanically locked, and the driver's
door lock actuator switch applies ground to the
oower door lock control unit. The control unit then
applies battery voltage to the WHT/RED wire and
ground to the YEURED wire, activating the
passenger door lock actuators which lock the doors.
Dool Locking with Transmitter
When you press the LOCK button on the remote
transmitter, the power door lock control unit applies
battery voltage to the WHT/RED wire and ground to
the YEURED wire. The passenger door lock
actuators then activate and lock the doors. A ground
slgnal is also applied to the BLU/RED wire to lock
the driver's door. lf any door is open, you cannot lock
it using the remote transmitter.
Door Unlocking (With or Without Keyless Entry)
When you push the driver's power door lock switch
to the unlock position, ground is applied to the
GRN/ORN wire to the power door lock control unit.
The control unit then applies battery voltage to the
YEURED and BLU/RED wires and ground to the
WHT/RED wire. The door lock actuators then
activate to unlock the doors.
When you unlock the driver's door with the key or
the door lock knob, it is mechanically unlocked; the
other doors do not unlock.
Door Unlocking (With Transmltter)
When you press the UNLOCK button on lhe remote
transmitter once. the power door lock control unit
applies battery voltage to the WHT/RED wire and
ground to the BLU/RED wire to unlock the driver's
door. When you press the UNLOCK button twice,
the control unit then applies ground to the YEURED
wires to activate the passenger door locks. lf you do
not open a door within 30 seconds after unlocking
the doors with the transmitter, the doors
automatically relock.
Transmltter Programming
1 . Turn the ignition switch ON (ll).
2. Press and hold the Valet-Disarm button on the
radio (between the AM/FM button and the
CD/TAPE button) to enter the programming
mode. (Continue to hold the button during the
procedure, or programming will be cancelled.)
Check that the power door locks cycle to confirm
that you're in the programming mode.
3. Press the "LOCK' or "UNLOCK' button on the
transmitter. Check that the power door locks
cycle to confirm that the code was accepted.
4. Press the "LOCK" or "UNLOCK" button on each
of the remaining transmitters. (You can program
up to four transmitters per vehicle.)
5. After all the transmitters have been
programmed, release lhe Valet-Disarm button to
exit the programming mode.
Beep On/Oft Feature
'I . Press and hold the LOCK and OPTION buttons
on the transmitter.
2. Watch the transmitter's LED:
One flash: Beeo activated.
Two tlashes: Beeo deactivated.

Transmitter Programming
. Entering the programming mode cancels all
learned transmitter codes, so none of the
previously programmed transmitters will work.
You must reprogram all the transmitters once
you're in the programming mode.
. To keep the system from exiting the
programming mode, complete each step within 5
seconds of the previous step, and program the
transmitters within 10 seconds of each other.'1 . Turn the ignition switch ON (ll).
2. Press the "LOCK" or "UNLOCK" button on one
of the transmitters. (A non-programmed
transmitter can be used for this step.)
3. Turn the ignition switch OFF (0).
4. Repeat steps 1, 2, and 3 two more times with
the transmitter used in step 2.
5. Turn the ignition switch ON (ll).
6. Press the "LOCK" or "UNLOCK" button on the
same transmitter. Check that the power door
locks cycle to confirm that you're in the
programmrng mooe.
7. Press the "LOCK" or "UNLOCK" button on each
lransmitter. (You can program up to four
lransmitters per vehicle.) Check that the power
door locks cycle after you push each transmitter
button, contirming that the system has accepted
the transmitter's code.
Beep On/Off Feature
1 . Press and hold the LOCK and OPTION buttons
on the transmitter.
2. Watch the transmitter's LED:
One flash: BeeD activated.
Two flashes: Beep deactivated.
