Power Door Locks (conrd)
- How the Circuit Works
Keyless Entry System
The keyless door locks combine the power door
locks with a remote key-fob transmitter. The keyless
door lock control unit receives direct inputs from the
ignition key switch, the passenger door switches,
and an indirect inDut from the driver's door switch
through the integrated control unit.
Power Door Locks
The power door lock system rs made up ot the
keyless 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.
Transmittel
The transmitter sends coded radio wave signals to
the keyless door lock conlrol unit when one of its
buttons is pressed. Each transmitter has a unique
code that must be 'laught" to the conlrol unit before
it can operate the door locks or any other function.
Up to 4 transmitters can be programmed to operate
the keyless door locks.
Door Locking
When you push the driveas door lock switch to the
lock position, ground is applied to the GRNMHT
wire to the keyless 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 dnver'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.
Door Locking with Transmitter
When you press the LOCK button on the remote
transmitter, the keyless door lock control unil 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
signal 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
When you push the driver's power door lock switch
to the unlock position, ground is applied to the
GRN/ORN wire to the keyless door lock control unil.
The control unit then applies battery voltage to the
YEUREO and BLU/RED wires and oround 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 Transmitter
When you press the UNLOCK button on the remote
transmitter once, the keyless 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 lo 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.
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.
