Circuit Schematics
oa
Each schematic represents one circult. A
circuit's wires and components are arranged
to show current flow, from power at the top of
the page, to ground, at the bottom.
Shared Circuits
Other circuits may share power or ground
terminals or wiring with the circuit shown. A
wire that connects one circuit to another, for
example, is cut short and has an arrowhead
at the end of it pointing in the direction of
current flow. Nelit to the anowhead is the
name o{ the circuil or comoonent which
shares that wiring. To quickly check shared
wiring, check the operation of a component it
serves. lf that component works, you know
the shared wiring is OK.
Connectors
All in-line and fuse box connectors are
numbered (C725, C416, etc.).
Component connectors are not numbered
but are identiJied by the name of the
component. lf a componenl has more than
one connector, each connector is assigned
a letter (A, B, C, etc.). Below most connector
numbers and comDonent names are
PHOTO and VIEW numbers. The PHOTO
number refers to a Dhoto in the back of the
book that shows lhe conneclor's location on
the car. The VIEW number refers to an
illustration in the back of the book that
shows the connector face, wire colors,
connector cavity numbers, and other details.
The connector cavity numbering sequence
begins at the top left corner oJ the connector
as seen from either of the viewooints shown
on page ffl . Disregard any numbers
molded into the connector housino.
Wires
Wires are identilied by the abbreviated
names of their colors; the second color rs the
color of the stripe. Wires are also identified by
their location in a connector. The number '2"
next to the male and female wire terminals at
C416, for example, means those terminals
join in cavity 2 of connector C416.

Troubleshooting Tests
Testing for Voltage Drop
Wires, connectors, and switches are designed
to conduct current wilh a minimum loss of
voltage. A voltage drop of more than one volt
indicates a Droblem.
'1. Place the digital volVohmmeter (DVOM) in
the appropriate DC volts range. Connect
the positive lead to the end of the wire
(or to the connector or switch) closest to
the bafterv.
Connect the negative lead to the other
end of the wire (or the other side of the
connector or switch).
Turn on the components in the circuit.
The DVOM will show the difference
in voltage between the two points. A
difference, or drop, of more than one
volt indicates a oroblem. Check the
circuit for loose, dirty, or bent terminals.
co
Testing lor a Short with a Test Light or DVOM
1. Remove the blown fuse and disconnect
the load.
2. Connect a test light or digital
oltr'ohmmeter
(DVOM), switched to the appropnare DC
volts range, across the tuse lerminals to
make sure voltage is present. You might
have to turn the ignition switch to ON:
check the schematic to see.
<-s80RT TOGFOUNO
Disconnecl lheload here.
Beginning near the luse box, wiggle the
harness. Continue this at convenient ooints
about six inches apart while watching the
test light or DVOM.
Where the test light goes off, or the DVOM
voltage drops to zero, there is a short to
ground in the wiring near that point.
NOTE: Always use a DVOM on high
impedance circuits. A test light may not
glow (even with battery voltage present).

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

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).
