DESCRIPTION AND OPERATION
HOW TO USE THIS GROUP
The purpose of this group is to show the electrical
circuits in a clear, simple fashion and to make trou-
bleshooting easier. Components that work together
are shown together. All electrical components used in
a specific system are shown on one diagram. The feed
for a system is shown at the top of the page. All
wires, connectors, splices, and components are shown
in the flow of current to the bottom of the page. Wir-
ing which is not part of the circuit represented is ref-
erenced to another page/section, where the complete
circuit is shown. In addition, all switches, compo-
nents, and modules are shown in theat rest posi-
tion with the doors closed and the key removed
from the ignition.
If a component is part of several different circuits,
it is shown in the diagram for each. For example, the
headlamp switch is the main part of the exterior
lighting, but it also affects the interior lighting and
the chime warning system.It is important to real-
ize that no attempt is made on the diagrams to
represent components and wiring as they
appear on the vehicle. For example, a short
piece of wire is treated the same as a long one.
In addition, switches and other components are
shown as simply as possible, with regard to
function only.
SECTION IDENTIFICATION
Sections in Group 8W are organized by sub-sys-
tems. The sections contain circuit operation descrip-
tions, helpful information, and system diagrams. The
intention is to organize information by system, con-
sistently from year to year.
CONNECTOR/GROUND LOCATIONS
Section 8W-90 contains connector/ground location
illustrations. The illustrations contain the connector
name (or number)/ground number and component
identification. Connector/ground location charts in
Section 8W-90 reference the illustration number for
components and connectors.
Section 8W-80 shows each connector and the cir-
cuits involved with that connector. The connectors
are identified using the name/number on the Dia-
gram pages.
SPLICE LOCATIONS
Splice Location charts in Section 8W-70 show the
entire splice, and provide references to other sections
the splice serves.
Section 8W-95 contains illustrations that show the
general location of the splices in each harness. The
illustrations show the splice by number, and provide
a written location.

Downloaded from www.Manualslib.com manuals search engine NOTES, CAUTIONS, and WARNINGS
Throughout this group additional important infor-
mation is presented in three ways; Notes, Cautions,
and Warnings.
NOTESare used to help describe how switches or
components operate to complete a particular circuit.
They are also used to indicate different conditions
that may appear on the vehicle. For example, an
up-to and after condition.
CAUTIONSare used to indicate information that
could prevent making an error that may damage the
vehicle.
WARNINGSprovide information to prevent per-
sonal injury and vehicle damage. Below is a list of
general warnings that should be followed any time a
vehicle is being serviced.
WARNING: ALWAYS WEAR SAFETY GLASSES FOR
EYE PROTECTION.
WARNING: USE SAFETY STANDS ANYTIME A PRO-
CEDURE REQUIRES BEING UNDER A VEHICLE.
WARNING: BE SURE THAT THE IGNITION SWITCH
ALWAYS IS IN THE OFF POSITION, UNLESS THE
PROCEDURE REQUIRES IT TO BE ON.
WARNING: SET THE PARKING BRAKE WHEN
WORKING ON ANY VEHICLE. AN AUTOMATIC
TRANSMISSION SHOULD BE IN PARK. A MANUAL
TRANSMISSION SHOULD BE IN NEUTRAL.
WARNING: OPERATE THE ENGINE ONLY IN A
WELL-VENTILATED AREA.
WARNING: KEEP AWAY FROM MOVING PARTS
WHEN THE ENGINE IS RUNNING, ESPECIALLY THE
FAN AND BELTS.
WARNING: TO PREVENT SERIOUS BURNS, AVOID
CONTACT WITH HOT PARTS SUCH AS THE RADIA-
TOR, EXHAUST MANIFOLD(S), TAIL PIPE, CATA-
LYTIC CONVERTER, AND MUFFLER.
WARNING: DO NOT ALLOW FLAME OR SPARKS
NEAR THE BATTERY. GASES ARE ALWAYS
PRESENT IN AND AROUND THE BATTERY.WARNING: ALWAYS REMOVE RINGS, WATCHES,
LOOSE HANGING JEWELRY, AND LOOSE CLOTH-
ING.
WIRE CODE IDENTIFICATION
Each wire shown in the diagrams contains a code
(Fig. 1) which identifies the main circuit, part of the
main circuit, gauge of wire, and color. The color is
shown as a two letter code which can be identified by
referring to the Wire Color Code Chart (Fig. 2)

DESCRIPTION AND OPERATION (Continued)

Downloaded from www.Manualslib.com manuals search engine CIRCUIT IDENTIFICATION
All circuits in the diagrams use an alpha/numeric
code to identify the wire and its function (Fig. 3). To
identify which circuit code applies to a system, refer
to the Circuit Identification Code Chart. This chart
shows the main circuits only and does not show the
secondary codes that may apply to some models.
CONNECTORS
Connectors shown in the diagrams are identified
using the international standard arrows for male and
female terminals (Fig. 4). A connector identifier is
placed next to the arrows to indicate the connector
number (Fig. 4).For viewing connector pin outs, with two terminals
or greater, refer to section 8W-80. This section iden-
tifies in-line connectors by number, and component
connectors by name. If a component has two or more
connectors they will be identified as C1, C2, C3...etc.
This sections also provides terminal numbering, cir-
cuit identification, wire colors, and functions.
All connectors are viewed from the terminal end
unless otherwise specified. To find the connector loca-
tion in the vehicle refer to section 8W-90. This sec-
tion uses the connector identification number from
the wiring diagrams to provide a figure number ref-
erence.
TAKE OUTS
The abbreviation T/O is used in the component
location section to indicate a point in which the wir-
ing harness branches out to a component.
SYMBOLS
Various symbols are used throughout the Wiring
Diagrams. These symbols can be identified by refer-
ring to the symbol identification chart (Fig. 5).

DESCRIPTION AND OPERATION (Continued)

Downloaded from www.Manualslib.com manuals search engine ELECTROSTATIC DISCHARGE (ESD) SENSITIVE
DEVICES
All ESD sensitive components are solid state and a
symbol (Fig. 6) is used to indicate this. When han-
dling any component with this symbol comply with
the following procedures to reduce the possibility of
electrostatic charge build up on the body and inad-
vertent discharge into the component. If it is not
known whether the part is ESD sensitive, assume
that it is.
(1) Always touch a known good ground before han-
dling the part. This should be repeated while han-
dling the part and more frequently after sliding
across a seat, sitting down from a standing position,
or walking a distance.
(2) Avoid touching electrical terminals of the part,
unless instructed to do so by a written procedure.
(3) When using a voltmeter, be sure to connect the
ground lead first.
(4) Do not remove the part from its protective
packing until it is time to install the part.
(5) Before removing the part from its package,
ground the package to a known good ground on the
vehicle.
FASTENERS
CAUTION: At no time when servicing a vehicle, can
a sheet metal screw, bolt, or other metal fastener be
installed in the strut tower to take the place of an
original plastic clip. Also, NO holes can be drilled
into the front strut tower in the area shown in (Fig.
7) for the installation of any metal fasteners into the
strut tower. Because of the minimum clearance in
this area (Fig. 7) installation of metal fasteners
could damage the coil spring coating and lead to a
corrosion failure of the spring. If a plastic clip is
missing, or is lost or broken during servicing a
vehicle, replace only with the equivalent part listed
in the parts catalog.
POSITIVE TEMPERATURE COEFFICIENT
Positive Temperature Coefficient (PTC) devices are
being used for circuit protection. These PTC's act like
a solid state fuse. They are located in the junction
block, and are used to protect such items as: power
door lock motors, power windows, and various engine
solenoids.
A special symbol is used to identify these in the
wiring diagrams (Fig. 8).
DIAGNOSIS AND TESTING
TROUBLESHOOTING TOOLS
When diagnosing a problem in an electrical circuit
there are several common tools necessary. These tools
are listed and explained below.
²Jumper Wire - This is a test wire used to con-
nect two points of a circuit. It can be used to bypass
an open in a circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS
A LOAD, SUCH AS A MOTOR, CONNECTED
BETWEEN A BATTERY FEED AND GROUND.

DESCRIPTION AND OPERATION (Continued)

Downloaded from www.Manualslib.com manuals search engine ²Voltmeter - Used to check for voltage on a cir-
cuit. Always connect the black lead to a known good
ground and the red lead to the positive side of the
circuit.
CAUTION: Most of the electrical components used
in today's vehicle are solid state. When checking
voltages in these circuits use a meter with a 10-me-
gohm or greater impedance.
²Ohmmeter - Used to check the resistance
between two points of a circuit. Low or no resistance
in a circuit means good continuity.
CAUTION: - Most of the electrical components used
in today's vehicle are Solid State. When checking
resistance in these circuits use a meter with a
10-megohm or greater impedance. In addition, make
sure the power is disconnected from the circuit.
Circuits that are powered up by the vehicle electri-
cal system can cause damage to the equipment and
provide false readings.
²Probing Tools - These tools are used for probing
terminals in connectors (Fig. 9). Select the proper
size tool from Special Tool Package 6807, and insert
it into the terminal being tested. Use the other end
of the tool to insert the meter probe.
INTERMITTENT AND POOR CONNECTIONS
Most intermittent electrical problems are caused
by faulty electrical connections or wiring. It is also
possible for a sticking component or relay to cause a
problem. Before condemning a component or wiring
assembly check the following items.
²Connectors are fully seated
²Spread terminals, or terminal push out
²Terminals in the wiring assembly are fully
seated into the connector/component and locked in
position
²Dirt or corrosion on the terminals. Any amount
of corrosion or dirt could cause an intermittent prob-
lem
²Damaged connector/component casing exposing
the item to dirt and moisture²Wire insulation that has rubbed through causing
a short to ground
²Wiring broke inside of the insulation
CHECKING FOR TERMINAL SPREADING
When an intermittent or open circuit is suspected
it is important to check for a spread terminal. To
accomplish this remove the suspect female terminal
from its connector.
Check the female terminal for drag when mated
with the appropriate male terminal. If the terminal
is spread (no or little drag felt) replace the terminal
using the procedures covered in this section of the
wiring diagrams.
TROUBLESHOOTING TESTS
Before beginning any tests on a vehicles electrical
system use the Wiring Diagrams and study the cir-
cuit. Also refer to the Troubleshooting Wiring Prob-
lems section in this section.
TESTING FOR VOLTAGE
(1) Connect the ground lead of a voltmeter to a
known good ground (Fig. 10).
(2) Connect the other lead of the voltmeter to the
selected test point. The vehicle ignition may need to
be turned ON to check voltage. Refer to the appropri-
ate test procedure.
TESTING FOR CONTINUITY
(1) Remove the fuse for the circuit being checked
or, disconnect the battery.
(2) Connect one lead of the ohmmeter to one side
of the circuit being tested (Fig. 11).
