to-metal contact between components, due
to flexible rubber mountings, etc.
To check whether a component is properly
earthed, disconnect the battery, 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.
If an earth connection is thought to be
faulty, dismantle the connection, and clean
back to bare metal both the bodyshell and the
wire terminal or the component earth
connection mating surface. 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
remade, prevent the onset of corrosion in the
future by applying a coat of petroleum jelly or
silicone-based grease.
3Fuses and relays - general
Fuses
1Fuses are designed to break a circuit when
a predetermined current is reached, to protect
the components and wiring which could be
damaged by excessive current flow. Any
excessive current flow will be due to a fault in
the circuit, usually a short-circuit (Section 2).
2The main fuses and relays are located in a
panel at the lower right-hand side of the facia,
under a hinged cover (see illustration).
3The circuits protected by the various fuses
and relays are marked on the inside of the
panel cover.
4A blown fuse can be recognised from its
melted or broken wire.
5To remove a fuse, first ensure that the
relevant circuit is switched off. Then open the
cover and pull the relevant fuse or relay from the
panel (see illustration). If desired, the lower
end of the panel can be tilted forwards, after
releasing the retaining clips to improve access. 6Before renewing a blown fuse, trace and
rectify the cause, and always use a fuse of the
correct rating. Never substitute a fuse of a
higher rating, or make temporary repairs using
wire or metal foil, as more serious damage or
even fire could result.
7Spare fuses are provided in the blank
terminal positions in the fusebox.
8Note that the fuses are colour-coded, see
Specifications. Refer to the wiring diagrams
for details of the fuse ratings and the circuits
protected.
Relays
9A relay is an electrically operated switch,
which is used for the following reasons:
a)A relay can switch a heavy current
remotely from the circuit in which the
current is flowing, allowing the use of
lighter-gauge wiring and switch contacts.
b)A relay can receive more than one control
input, unlike a mechanical switch.
c)A relay can have a timer function - for
example, the intermittent wiper relay.
10Most of the relays are located at the rear
of the main fusebox (remove the securing
screws and pull the fusebox forwards to
improve access). The rear wiper motor relay is
located in the tailgate, behind the tailgate trim
panel. On some models, additional engine-
related relays are located in the relay box
mounted on the left-hand side of the engine
compartment.
11On certain models, additional relays are
located in a box at the left-hand rear of the
engine compartment (see illustration).
12If a circuit or system controlled by a relay
develops a fault, and the relay is suspect,
operate the system. If the relay is functioning, it
should be possible to hear it “click” as it is
energised. If this is the case, the fault lies with
the components or wiring of the system. If the
relay is not being energised, then either the
relay is not receiving a main supply or a
switching voltage, or the relay itself is faulty.
Testing is by the substitution of a known good
unit, but be careful - while some relays are
identical in appearance and in operation, others
look similar but perform different functions.
13To remove a relay, first ensure that the
relevant circuit is switched off. The relay can
then simply be pulled out from the socket,
and pushed back into position.

Removal
1Disconnect the battery negative lead.
2Turn the steering wheel as necessary to
expose the two front steering column shroud
securing screws, which are covered by plastic
caps. Prise out the caps and remove the
screws.
3Remove the three securing screws from the
underside of the lower column shroud, then
remove both the upper and lower shrouds.
4To remove the lock cylinder, insert the
ignition key and turn it to position “II”.
5Insert a thin rod into the hole in the lock
housing, then press the rod to release the
detent spring, and pull out the lock cylinder
using the key.
6The ignition switch is secured to the
steering lock housing by two grub screws.
Disconnect the wiring plug, and remove the
screws to extract the switch (see illustration).
Removal of the steering wheel, may aid
removal. Refer to Chapter 10 or Section 57, as
applicable. It is recommended that the switch
and the lock cylinder are not both removed at
the same time, so that their mutual alignment
is not lost.

removal and refitting
4
Note:On power steering models in particular,
it will be advantageous to jack up the front of
the car and support it on axle stands placed
under the body side members, so that the
steering wheel can be turned more easily.
Removal
1Disconnect the battery negative lead and
cover the battery terminal. Wait a minimum of 1
minute.
2With the steering wheel positioned in the
straight-ahead position, turn it 90°clockwise
so that the left-hand spoke is accessible from
the rear.
3Using a Torx type socket, undo the first
airbag retaining bolt from the rear of the
steering wheel (see illustration).
4Turn the steering wheel 180°anti-clockwise
so that the right-hand spoke is accessible
from the rear.
5Undo the second retaining bolt from the
rear of the steering wheel.
6Return the steering wheel to the
straight-ahead position then carefully lift up
the airbag unit.
7Disconnect the wiring plug and remove the
airbag from the car.

8Refitting is a reversal of removal.
57Steering wheel (with airbag)
-removal and refitting
4
Note: Read warning at the beginning of
Section 55, before starting work. A
two-legged puller will be required for this
operation. Note also that the steering wheel is
a very tight fit on the shaft.
Removal
1Remove the airbag unit as described
previously.
2Ensure that the steering wheel is in the
straight ahead position.
3From the centre of the steering wheel
unscrew the two screws securing the airbag
contact unit.4Using a screwdriver, prise back the tabs on
the lockwasher securing the steering wheel
retaining nut.
5Unscrew and remove the steering wheel
retaining nut and the lockwasher.
6Make alignment marks between the
steering wheel and the end of the column
shaft.
7A suitably small two-legged puller must
now be fitted to the steering wheel in order to
pull it from the column shaft.
8Once the steering wheel has been released
from the column shaft, disconnect the horn
wiring and remove the steering wheel.
Refitting
9Begin refitting by positioning the steering
wheel on the column shaft, ensuring that the
marks made on removal are aligned, and that
the wheel correctly engages with the airbag
contact unit. It may be necessary to tap the
steering wheel fully home on the column shaft
using a metal tube and socket.
10Reconnect the horn wiring.
11Refit the lockwasher and the steering
wheel retaining nut, and tighten the nut to the
specified torque. Bend up the lockwasher to
secure.
12Refit the two screws securing the airbag
contact unit.
13Refit the airbag as described previously.
