models (see illustration). In other countries, it
is available on certain models only. Where
double-locking is fitted, the lock mechanism
is disconnected (when the system is in use)
from the interior door handles, making it
impossible to open any of the doors or the
tailgate/bootlid from inside the vehicle. This
means that, even if a thief should break a side
window, he will not be able to open the door
using the interior handle. Models with the
double-locking system are fitted with a
control module located beneath the facia on
the right-hand side. In the event of a serious
accident, a crash sensor unlocks all doors if
they were previously locked.
Many of the procedures in this Chapter
require the battery to be disconnected. Refer
to Chapter 5, Section 1 first.
The general condition of a vehicle’s
bodywork is the one thing that significantly
affects its value. Maintenance is easy, but
needs to be regular. Neglect, particularly after
minor damage, can lead quickly to further
deterioration and costly repair bills. It is
important also to keep watch on those parts
of the vehicle not immediately visible, for
instance the underside, inside all the wheel
arches, and the lower part of the engine
compartment.
The basic maintenance routine for the
bodywork is washing - preferably with a lot of
water, from a hose. This will remove all the
loose solids which may have stuck to the
vehicle. It is important to flush these off in
such a way as to prevent grit from scratching
the finish. The wheel arches and underframe
need washing in the same way, to remove any
accumulated mud, which will retain moisture
and tend to encourage rust. Paradoxically
enough, the best time to clean the underframe
and wheel arches is in wet weather, when the
mud is thoroughly wet and soft. In very wet
weather, the underframe is usually cleaned of
large accumulations automatically, and this is
a good time for inspection.
Periodically, except on vehicles with a wax-
based underbody protective coating, it is a
good idea to have the whole of the
underframe of the vehicle steam-cleaned,
engine compartment included, so that a
thorough inspection can be carried out to see
what minor repairs and renovations are
necessary. Steam-cleaning is available at
many garages, and is necessary for the
removal of the accumulation of oily grime,
which sometimes is allowed to become thick
in certain areas. If steam-cleaning facilities are
not available, there are some excellent grease
solvents available which can be brush-
applied; the dirt can then be simply hosed off.
Note that these methods should not be used
on vehicles with wax-based underbodyprotective coating, or the coating will be
removed. Such vehicles should be inspected
annually, preferably just prior to Winter, when
the underbody should be washed down, and
any damage to the wax coating repaired.
Ideally, a completely fresh coat should be
applied. It would also be worth considering
the use of such wax-based protection for
injection into door panels, sills, box sections,
etc, as an additional safeguard against rust
damage, where such protection is not
provided by the vehicle manufacturer.
After washing paintwork, wipe off with a
chamois leather to give an unspotted clear
finish. A coat of clear protective wax polish
will give added protection against chemical
pollutants in the air. If the paintwork sheenhas dulled or oxidised, use a cleaner/polisher
combination to restore the brilliance of the
shine. This requires a little effort, but such
dulling is usually caused because regular
washing has been neglected. Care needs to
be taken with metallic paintwork, as special
non-abrasive cleaner/polisher is required to
avoid damage to the finish. Always check that
the door and ventilator opening drain holes
and pipes are completely clear, so that water
can be drained out. Brightwork should be
treated in the same way as paintwork.
Windscreens and windows can be kept clear
of the smeary film which often appears, by the
use of proprietary glass cleaner. Never use
any form of wax or other body or chromium
polish on glass.

Testing
1The central locking module incorporates a
service-test mode, which is activated by
operating one of the lock position switches 8
times within 10 seconds. A buzzer will sound,
to indicate that the service-test mode is
operating, and to indicate that no faults have
been found in the system. If a fault has been
found, the system should be checked by a
Ford dealer or electrical specialist. The central
locking module also incorporates the alarm
system module.

It should be noted that, when portions of
the electrical system are serviced, the cable
should be disconnected from the battery
negative terminal, to prevent electrical shorts
and fires.
Caution: When disconnecting the
battery for work described in the
following Sections, refer to
Chapter 5, Section 1.
Note:Refer to the precautions given in
“Safety first!” and in Section 1 of this Chapter
before starting work. The following tests relate
to testing of the main electrical circuits, and
should not be used to test delicate electronic
circuits (such as engine management systems,
anti-lock braking systems, etc), particularly
where an electronic control module is used.
Also refer to the precautions given in Chapter
5, Section 1.
General
1A typical electrical circuit consists of an
electrical component, any switches, relays,
motors, fuses, fusible links or circuit breakers
related to that component, and the wiring and
connectors which link the component to both
the battery and the chassis. To help to
pinpoint a problem in an electrical circuit,
wiring diagrams are included at the end of this
manual.
2Before attempting to diagnose an electrical
fault, first study the appropriate wiring
diagram, to obtain a complete understanding
of the components included in the particular
circuit concerned. The possible sources of a
fault can be narrowed down by noting if other
components related to the circuit are
operating properly. If several components or
circuits fail at one time, the problem is likely to
be related to a shared fuse or earth
connection.
3Electrical problems usually stem from
simple causes, such as loose or corroded
connections, a faulty earth connection, a
blown fuse, a melted fusible link, or a faulty
relay (refer to Section 3 for details of testing
relays). Visually inspect the condition of all
fuses, wires and connections in a problem
circuit before testing the components. Use
the wiring diagrams to determine which
terminal connections will need to be checked
in order to pinpoint the trouble-spot.
4The basic tools required for electrical fault-
finding include a circuit tester or voltmeter (a
12-volt bulb with a set of test leads can alsobe used for certain tests); an ohmmeter (to
measure resistance and check for continuity);
a battery and set of test leads; and a jumper
wire, preferably with a circuit breaker or fuse
incorporated, which can be used to bypass
suspect wires or electrical components.
Before attempting to locate a problem with
test instruments, use the wiring diagram to
determine where to make the connections.
5To find the source of an intermittent wiring
fault (usually due to a poor or dirty
connection, or damaged wiring insulation), a
“wiggle” test can be performed on the wiring.
This involves wiggling the wiring by hand to
see if the fault occurs as the wiring is moved.
It should be possible to narrow down the
source of the fault to a particular section of
wiring. This method of testing can be used in
conjunction with any of the tests described in
the following sub-Sections.
6Apart from problems due to poor
connections, two basic types of fault can
occur in an electrical circuit - open-circuit, or
short-circuit.
7Open-circuit faults are caused by a break
somewhere in the circuit, which prevents
current from flowing. An open-circuit fault will
prevent a component from working.
8Short-circuit faults are caused by a “short”
somewhere in the circuit, which allows the
current flowing in the circuit to “escape” along
an alternative route, usually to earth. Short-
circuit faults are normally caused by a
breakdown in wiring insulation, which allows a
feed wire to touch either another wire, or an
earthed component such as the bodyshell. A
short-circuit fault will normally cause the
relevant circuit fuse to blow.
Finding an open-circuit
9To check for an open-circuit, connect one
lead of a circuit tester or the negative lead of a
voltmeter either to the battery negative
terminal or to a known good earth.
10Connect the other lead to a connector in
the circuit being tested, preferably nearest to
the battery or fuse. At this point, battery
voltage should be present, unless the lead
from the battery or the fuse itself is faulty
(bearing in mind that some circuits are live
only when the ignition switch is moved to a
particular position).
11Switch on the circuit, then connect the
tester lead to the connector nearest the circuit
switch on the component side.
12If voltage is present (indicated either by
the tester bulb lighting or a voltmeter reading,
as applicable), this means that the section of
the circuit between the relevant connector
and the switch is problem-free.
13Continue to check the remainder of the
circuit in the same fashion.
14When a point is reached at which no
voltage is present, the problem must lie
between that point and the previous test point
with voltage. Most problems can be traced to
a broken, corroded or loose connection.
Finding a short-circuit
15To check for a short-circuit, first
disconnect the load(s) from the circuit (loads
are the components which draw current from
a circuit, such as bulbs, motors, heating
elements, etc).
16Remove the relevant fuse from the circuit,
and connect a circuit tester or voltmeter to the
fuse connections.
17Switch on the circuit, bearing in mind that
some circuits are live only when the ignition
switch is moved to a particular position.
18If voltage is present (indicated either by
the tester bulb lighting or a voltmeter reading,
as applicable), this means that there is a
short-circuit.
19If no voltage is present during this test,
but the fuse still blows with the load(s)
reconnected, this indicates an internal fault in
the load(s).
Finding an earth fault
20The battery negative terminal is
connected to “earth” - the metal of the
engine/transmission unit and the vehicle body
- and many systems are wired so that they
only receive a positive feed, the current
returning via the metal of the car body. This
means that the component mounting and the
body form part of that circuit. Loose or
corroded mountings can therefore cause a
range of electrical faults, ranging from total
failure of a circuit, to a puzzling partial failure.
In particular, lights may shine dimly (especially
when another circuit sharing the same earth
point is in operation), motors (eg wiper motors
or the radiator cooling fan motor) may run
slowly, and the operation of one circuit may
have an apparently-unrelated effect on
another. Note that on many vehicles, earth
straps are used between certain components,
such as the engine/transmission and the
body, usually where there is no metal-to-
metal contact between components, due to
flexible rubber mountings, etc.
21To check whether a component is
properly earthed, disconnect the battery (refer
to Chapter 5, Section 1) and connect one lead
of an ohmmeter to a known good earth point.
Connect the other lead to the wire or earth
connection being tested. The resistance
reading should be zero; if not, check the
connection as follows.
22If an earth connection is thought to be
faulty, dismantle the connection, and clean
both the bodyshell and the wire terminal (or
the component earth connection mating
surface) back to bare metal. Be careful to
remove all traces of dirt and corrosion, then
use a knife to trim away any paint, so that a
clean metal-to-metal joint is made. On
reassembly, tighten the joint fasteners
securely; if a wire terminal is being refitted,
use serrated washers between the terminal
and the bodyshell, to ensure a clean and
secure connection. When the connection is
