D Powertrain Control/Emissions Diag-

nosis Manuals

Ford Customer Service Division has developed a new format for the 2001 Electric Ranger Wiring Diagrams. Our goal is to

provide accurate and timely electrical information.

D Schematic pages do not contain Component Location references to full-view illustrations and Component Descriptions

that describe the system function of a component. (This information is available in CELL 152 Location Index or the Work-
shop Manual.)

D “COMPONENT TESTING” procedures (CELL 149) that tell the user how to perform diagnostic tests on various circuits.

D NOTES, CAUTIONS and WARNINGS contain important safety information.

D Full view “COMPONENT LOCATION VIEWS” (CELL 151) to help locate on-vehicle components.

D Circuit voltages have been added to schematic pages to help simplify troubleshooting.

Nonessential troubleshooting hints have been deleted.

D Cellular Pagination: A specific section (or cell) in all Wiring Diagrams is numbered by cell and starts with page 1. For ex-

ample: “HOW TO USE THIS MANUAL” is CELL 2 and begins with page 2-1.

D “CONNECTOR FACES” (CELL 150) will contain all connectors, to aid in servicing electrical wiring.

D “C” numbers have been assigned for all electrical connectors. “C” numbers are listed in the

“LOCATION INDEX” (CELL 152).

D “HARNESS CAUSAL PART NUMBERS” (CELL 153) has been added to aid in identifying warranty concerns.

D In-line connector numbers contain a suffix to denote connector “gender” type (F-socket, M-prior blade).

D HIGH VOLTAGE WIRES are identified by “white” wires with a black outline. Black stripes may also appear on these wires,

indicating a tracer. Wiring harnesses with high voltage wiring will be identified in the vehicle by orange convolute around
that harness auxiliary loads such as the A/C system, power steering pump, heater and certain control components. These
components should be treated with extreme caution. Do not perform any service on them until all high voltage power has
been disconnected.

NOTE: The descriptions and specifications contained in this manual were in effect at the time this manual was

approved for printing. Ford Motor Company reserves the right to discontinue models at any time, or change

specifications or design without notice and without incurring any obligation.

HOW TO USE THIS MANUAL

The purpose of this manual is to show electrical cir-

cuits in a clear and simple fashion to make trouble-
shooting easier. NOTES, CAUTIONS and WARN-
INGS contain important information.

D NOTES describe how switches and other compo-

nents operate to help complete a particular pro-
cedure.

D CAUTIONS provide information that could pre-

vent making an error that may damage the
vehicle.

D WARNINGS provide information to prevent per-

sonal injury.

The WARNINGS list on page 2-2 contains general

warnings to follow when servicing a vehicle.

Components that work together are shown

together. All electrical components used in a specific
system are shown on one diagram. The circuit
breaker or fuse is shown at the top of the page. All
wires, connectors, components and splices are
shown in the flow of current to ground at the bottom
of the page. If a component is used in several differ-
ent systems, it is shown in several places. For exam-
ple, the Headlamp Switch is electrically a part of
many systems and is repeated on many pages.

In some cases, a component may seem (by its

name) to belong to a system where it has no electri-
cal connection. For example, Radio Illumination is
electrically part of Instrument Illumination, but
because it has no electrical connection to the Radio
system, it is not shown on the Radio diagram.

Schematic pages contain references to full-view

illustrations and description notes for various com-
ponents. The references are reverse-text blocks
located next to each component and connector and
refer the user to the appropriate illustration page and
zone. The description notes describe the operation
of the component.

Schematic pages contain circuit voltages to help

simplify troubleshooting hints. 12V is used to imply
battery voltage on a component connector terminal,
and 0V is used to show that there should be continu-
ity to ground on that particular terminal. Conditional
voltages such as “12V with the ignition switch in
RUN” will also be provided. Troubleshooting hints
that can’t be simplified with circuit voltages will be
shown at the end of each cell.

Component connector face information specific to

a certain cell is found at the end of that cell. A Con-
nector Face Reference List is provided to locate con-
nector faces that are shown in different cells. Com-
ponent connectors with five or more terminals are
illustrated and are accompanied by a pinout chart
that lists the function of all circuitry associated with
that component.

“GROUNDS” (Cell 10) contains ground circuitry

shown in complete detail. This information is useful
for checking interconnections of the ground circuits
of different systems.

“POWER DISTRIBUTION” (Cell 13) contains

power distribution circuitry shown in complete detail.
This section displays how the various fuses are pow-
ered and, in turn, how each system is powered.

“COMPONENT TESTING” (Cell 149) contains

testing procedures for various switches. This
information includes schematics, component termi-
nal locations and step-by-step procedures.

“IN-LINE CONNECTOR FACES” (Cell 150) con-

tains illustrations of all the in-line connectors that
have 6 or more terminals. The terminals have pin
numbers assigned to them.

“COMPONENT LOCATION VIEWS” (Cell 151)

contains full-view illustrations which show the loca-
tion of components and connectors in the vehicle.

The “LOCATION INDEX” (Cell 152) provides the

base part numbers, locations, connector face refer-
ences and illustration references for all components,
connectors, splices and grounds.

HELPFUL REMINDERS

Before using the Wiring Diagrams for troubleshoot-

ing, refer to these HELPFUL REMINDERS:

1. The abbreviation T/O, for take out, used in the

Location Index (Cell 152), refers to the point at
which a group of wires branch off the harness
trunk. Refer to the wiring harness illustration.

2. If a connector serves the same purpose in two

separate versions (e.g., Automatic/Manual), but
is physically different, two connector numbers
are used. However, if a connector serves the
same purpose in two separate versions (e.g.,
Automatic/Manual) and is physically the same,
but the wire colors are different, only one connec-
tor number is used. If the same physical connec-
tor is used more than once, then more than one
connector number is used.

3. Wiring schematics provide a picture of how and

under what conditions the circuit is powered, of
the current path to circuit components, and of
how a circuit is grounded. Each circuit compo-
nent is named (underlined titles). Wire and con-
nector colors are listed as follows (standard Ford
color abbreviations are used):

Ford Customer Service Division, refer to Cell 160
(beginning on page 160-1). Note: Do not use the
illustrations in Cell 151 (beginning on page 151-1)
for reporting Vehicle Repair Location Codes.

5. WARNINGS

D Always wear safety glasses for eye protec-

tion.

D Use safety stands whenever a procedure

requires being under a vehicle.

D Be sure that the Ignition Switch is always

in the OFF position, unless otherwise
required by the procedure.

D Set the parking brake when working on any

vehicle. An automatic transmission should
be in PARK. A manual transmission should
be in NEUTRAL.

D Operate the engine only in a well-ventilated

area to avoid danger of carbon monoxide.

D Keep away from moving parts, especially the

fan and belts, when the engine is running.

D To prevent serious burns, avoid contact with

hot metal parts such as the radiator, exhaust
manifold, tail pipe, catalytic converter and
muffler.

D Do not allow flame or sparks near the battery.

Gases are always present in and around the
battery cell. An explosion could occur.

D Do not smoke when working on a vehicle.
D To avoid injury, always remove rings,

watches, loose hanging jewelry and avoid
wearing loose clothing.

HOW TO FIND ELECTRICAL
CONCERNS

TROUBLESHOOTING STEPS

These six steps present an orderly method of trou-

bleshooting.

Step 1. Verify the concern.

D Operate the complete system to check the accu-

racy and completeness of the customer’s com-
plaint.

Step 2. Narrow the concern.

D Using the Wiring Diagrams, narrow down the

possible causes and locations of the concern to
pinpoint the exact cause.

D Read the description notes at the components

and study the wiring schematic. You should then
know enough about the circuit operation to deter-
mine where to check for the trouble. Further
information can be found by referring to the Work-
shop Manual pages listed in the box at the top of
the page.

Step 3. Test the suspected cause.

D Use electrical test procedures to find the specific

cause of the symptoms.

D The component location reference bars and the

pictures will help you find components. The Loca-
tion Index (at the end of the manual) gives com-
ponent location information for connectors,
diodes, resistors, splices and grounds.

Step 4. Verify the cause.

D Confirm that you have found the correct cause by

connecting jumper wires and/or temporarily
installing a known good component and operat-
ing the circuit.

Step 5. Make the repair.

D Repair or replace the inoperative component.

Step 6. Verify the repair.

D Operate the system as in Step 1 and check that

your repair has removed all symptoms without
creating any new symptoms.
