21Remove the two securing screws, and
detach the motor from the lock assembly.
22Refitting is a reversal of removal, ensuring
that the motor operating rod engages with the
lock lever.
Note: The alarm system has a self-diagnosis
function, which allows a Ford dealer to carry
out fault diagnosis, using suitable specialist
equipment. In the event of a problem with the
alarm system, it is advisable not to tamper
with the components until appropriate fault
diagnosis has been carried out.Location
1From 1990, certain models are fitted with
an anti-theft alarm(see illustration).
2The alarm system consists of a control
module mounted behind the driver’s side
facia; trip switches fitted to the doors,
tailgate/boot lid, and bonnet; activating
switches fitted to the front door locks; an
additional horn mounted at the bulkhead next
to the battery and an indicator light mounted
on the top of the facia.
Module - removal and refitting
3Disconnect the battery negative lead.
4Release the carpet trim panel from under
the driver’s side facia. 5Reach up behind the facia and locate the
control module. Release the plastic retaining
clips using a screwdriver, and lower the
module.
6Disconnect the wiring plug and withdraw
the module.
7Refitting is a reversal of removal.
Removal
1Disconnect the battery negative lead.
2Remove the seat.
3Remove the seat cushion trim or backrest
trim as necessary.
4Note which way round the pad is fitted,
then remove the wire clips and adhesive tape
which secure it to the seat. Retrieve the tie-
rod and fit it to the new pad.
Refitting
5Fit the new pad with the thermostat facing
the cushion foam(see illustration).Secure
the pad with wire clips and tape, making sure
that it is not too tight - it must be able to flex
when sat on.
6Refit the cushion or backrest trim, as
applicable, being careful not to trap or kink
the pad.
7Refit the seat, reconnect the wiring and
check the pads for correct operation.
