illustration). If possible, it is preferable to
obtain purpose-made rods from an audio
specialist, as these have cut-outs which snap
firmly into the clips so that the radio can be
pulled out. Pull the unit squarely from its
aperture, or it may jam.
4 With the radio/cassette sufficiently
withdrawn, disconnect the feed, earth, aerial
and speaker leads.
5 Remove the tools from the unit by gently
wiggling and pulling.
Refitting
6 Refitting is a reversal of removal. When the
leads are reconnected to the rear of the unit,
press it into position to the point where the
retaining clips are felt to engage. Reactivate
the unit in accordance with the code and the
instructions given in the Ford Audio Operating
Manual supplied with the vehicle.

Note : The roof-mounted aerial mast section
should be removed prior to using an
automatic carwash. This is achieved by
unscrewing it from the aerial base.
Removal
1 Disconnect the battery negative (earth) lead
(refer to Chapter 5A, Section 1).
2 Unscrew the aerial mast section, then
remove the base section as follows. Insert a
thin flat-bladed screwdriver into the slot in the
interior (courtesy) light assembly and carefully
lever the assembly out.
3 Through the resultant opening, the aerial
base securing screw is accessible. Remove
the screw and detach the aerial base from the
roof of the vehicle, having noted the aerial
lead fitment.
Refitting
4 Refitting is a reversal of the removal
procedure, ensuring that the aerial base sits
squarely on the roof. Insert the switch end of
the light assembly to its aperture first, then
pivot the light upwards and push home to
secure.

Removal
The “lights-on” warning feature is fitted to
certain models from 1993 onwards. The
warning module, which resembles an ordinary
relay, is located behind the facia, between the
steering column and radio/cassette player. It
can be removed by reaching up behind the
facia and unclipping it from its mounting.

27 Anti-theft systems-
general information
Anti-theft alarm system
1 This system provides an added form of
vehicle security. When the system is
activated, the alarm will sound if the vehicle is
broken into through any one of the doors, the
bonnet, or tailgate. The alarm will also be
triggered if the ignition system is turned on or
the radio/cassette disconnected whilst the
system is activated.
2 This system is activated/de-activated
whenever one of the front doors is
locked/unlocked by the key. The system
operates on all doors, the bonnet and tailgate
whenever each door is individually locked (or,
in the case of central locking, when the central
locking is engaged). In addition, the
ignition/starting system is also immobilised
when the system is activated.
3 A further security feature included is that
even though the battery may be disconnected
whilst the system is activated, the alarm
activation continues as soon as the battery is
reconnected. Because of this feature, it is
important to ensure that the system is de-
activated before disconnecting the battery at
any time, such as when working on the
vehicle.
4 The system incorporates a diagnostic mode
to enable Ford technicians to quickly identify
any faults in the system. In the event of a
system malfunction, any testing or
component removal and refitting should be
entrusted to a Ford dealer.
Passive Anti-Theft System
(PATS)
5 From 1994 model year onwards, a Passive
Anti-Theft System (PATS) is fitted. This
system, (which works independently of the
standard alarm system) is a vehicle
immobiliser which prevents the engine from
being started unless a specific code,
programmed into the ignition key, is
recognised by the PATS transceiver.
6 The PATS transceiver, fitted around the
ignition switch, decodes a signal from the
ignition key as the key is turned from position
“O” to position “II”. If the coded signal
matches that stored in the memory of the
PATS module, the engine will start. If the
signal is not recognised, the engine will crank
on the starter but will not fire.

Warning: Handle the air bag
with extreme care as a
precaution against personal
injury, and always hold it with the cover facing away from your body. If in
doubt concerning any proposed work
involving the air bag or its control circuitry,
consult a Ford dealer or other qualified
specialist.
Removal

Disconnect the battery negative (earth) lead
(refer to Chapter 5A, Section 1). Warning: Before proceeding,
wait a minimum of 15 minutes,
as a precaution against
accidental firing of the air bag.
This period ensures that any stored energy
in the back-up capacitor is dissipated.
2 Undo the screws, and remove the steering
column lower shroud.
3 Undo the two external screws and the two
internal screws and remove the steering
column upper shroud.
4 Turn the steering wheel as necessary so
that one of the air bag module retaining bolts
becomes accessible from the rear of the
steering wheel. Undo the bolt, then turn the
steering wheel again until the second bolt is
accessible. Undo this bolt also.
5 Withdraw the air bag module from the
steering wheel far enough to access the
wiring multi-plug. Some force may be needed
to free the module from the additional steering
wheel spoke retainers.
6 Disconnect the multi-plug from the rear of
the module, and remove the module from the
vehicle. Warning: Position the air bag
module in a safe place, with the
mechanism facing downwards
as a precaution against
accidental operation.
Warning: Do not attempt to
open or repair the air bag unit,
or apply any electrical current to
it. Do not use any air bag which
is visibly damaged or which has been
tampered with.

until it is tight (see illustration) .
6 Now turn the outer rotor approximately
3.75 turns clockwise, then release the locking
pin. Ensure that the locking pin engages when
it is released.
