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.

1The windscreen and rear window on all
models are bonded in place with special
mastic, as are the rear side windows on
Estate models. Special tools are required to
cut free the old units and fit replacements;
special cleaning solutions and primer are also
required. It is therefore recommended that
this work is entrusted to a Ford dealer or
windscreen replacement specialist.
2Note that the windscreen contributes
towards the structural strength of the vehicle
as a whole, so it is important that it is fitted
correctly.

Warning: Before carrying out any
work on the electrical system,
read through the precautions
given in “Safety first!” at the beginning of
this manual.The electrical system is of 12-volt negative
earth type. Power for the lights and all
electrical accessories is supplied by a
lead/acid battery which is charged by the
alternator.
This Chapter covers repair and service
procedures for the various electrical
components not associated with the engine.
Information on the battery, ignition system,alternator, and starter motor can be found in
Chapter 5.
All models are fitted with a driver’s air bag,
which is designed to prevent serious chest
and head injuries to the driver during an
accident. A similar bag for the front seat
passenger is also available (see illustration).
The sensor and electronic unit for the air bag
is located next to the steering column inside
the vehicle, and contains a back-up capacitor,
crash sensor, decelerometer, safety sensor,
integrated circuit and microprocessor (see
illustration). The air bag is inflated by a gas
generator, which forces the bag out of the
module cover in the centre of the steering
wheel. A “clock spring” ensures that a good
electrical connection is maintained with the air
bag at all times - as the steering wheel is
turned in each direction, the spring winds and
unwinds.
All UK models are fitted with an alarm
system incorporating a movement sensor and
ignition immobiliser. On Saloon and
Hatchback models, the alarm system horn is
located on the left-hand side of the luggage

Removal
1Remove the windscreen wiper arms as
described in Section 15.
2With the bonnet closed, release the grille
panel upper edge from just in front of the
windscreen, by prising off the caps and

3Open the bonnet, and support with the
stay.
4Pull off the sealing strip from the cross
panel at the rear of the engine compartment.
5Unscrew the lower screws, and remove the
grille panel halves from in front of thewindscreen, withdrawing first one side and
then the other.
6Disconnect the battery negative (earth) lead
(refer to Chapter 5, Section 1).
7Reach in behind the bulkhead. Squeeze the
collar on the upper end of the speedometer
cable, where it is attached to the intermediate
cable from the rear of the speedometer head.
Disconnect the cable, and withdraw it from
the bulkhead inner panel, together with the
rubber grommet (see illustrations).
8Apply the handbrake, jack up the front of
the vehicle and support it on axle stands.
9Unscrew the nut and disconnect the
speedometer cable from the vehicle speed
sensor on the transmission, then withdraw the
cable from within the engine compartment.
Use two spanners to loosen the nut - one to
counterhold the sensor, and the other to
unscrew the cable nut (see illustrations).Refitting
