Sidelam
ps and Headlamps
Thes
e are controlled by rotating the end of the column switch as follows.
In the OFF position:
All
exterior lamps are switched OFF.
In the sidelamp position:
The front
sidelamps, tail, license plate and any other la
mps required by local legislation are switched ON.
The
sidelamps tell-tale lamp illuminates.
In the headlamp position, with the ignition switch in position II:
The h
eadlamps are switched ON in addition to the lamps switched on in the sidelamp position.
If the ignition is switched to the OFF position with the column switch in the headlamp position, the sidelamps, tail and
license plate lamps will stay ON, but the headlamps will switch OFF.
In the AUTO position (where fitted), with the ignition switch in position II:
Th
e sensor mounted on the back of the interior rear view
mirror monitors exterior light levels and automatically
switches the sidelamps and di pped headlamps ON and OFF.
The sensitivity level can be adjusted by turn ing the sensor control knob on the back of the interior mirror, left to decrease or
right to increase. The sensor must not be covered and the windscreen must be kept clean.

th the column switch in
the headlamp position:
Movin

m the steering wheel switches the headlamps to main beam.
Movin
g the switch stalk towards the steering wheel switches the headlamps to dipped beam.
The main beam tell-tale lamp illuminates when the headlamps are switched to main beam.
Ma
in Beam Flash
Wi
th the ignition switch and column switch in any position:
Pulling the

switch stalk agains
t spring pressure towards th e steering wheel illuminates the headlamps on main beam
for as long as the switch is held.
The main beam tell-tale lamp illuminates while the headlamps are illuminated.

Are se

lected by the button located at the end of the lighting switch stalk.
Are se

r to PDU User Guide
The c
o
mplexity of the electronics involved with the Instrument Cluster and the two multiplexed communication networks
which are connected to it, preclude the use of workshop genera l electrical test equipment. Therefore, reference should be
made to the PDU User Guide for detailed instructions on testing the Instrument Clus ter and associated circuits.
The PDU systematically test s and analyses all functions of the Instrument Clus ter, the various systems controlled by it and
individual sensors which are attached to each separate system.
Where a fault involving a remote sensor e. g. water temperature sensor, is indicated, before replacing the component, some
basic diagnostic methods may be necessary to confirm that connections are good and that wiring is not damaged.
Diagnostics using the PDU is via the CAN network, accessed at the diagnostic connector on the car.
Replaceable Parts
The only replaceable part s
are, General Illumination Bulbs, Direction Indicator Warning Bu
lbs and Main Beam Warning Bulb,
which are all of the conventional filament type. Other warning lamps are LEDs and are not replaceable.

Description and Operation
A multi-function switch located on the left stalk of the steering column switch assembly permits selection of either parking
(side), headlamps, auto-headlamp or off. Selection of a particular mode provides the appropriate input to the body
processor module (BPM).
Where the auto headlamp function is incorporated, a light sensor in the interior rear view mirror monitors ambient light and
provides an input to the BPM. The BPM responds by switching the low beam headlamps on or off as appropriate for the
prevailing light conditions.
The front and rear fog lamp switch is located on the fascia outboard of the steering column.
Front Lamps

Headlamp assembly
Each headlamp assembly consists of tw o headlamp units. The dipped beam lamp unit is located outboard and the main
beam lamp unit located inboard also carries the front parking (side) lamp. Access for bulb replacement is from the engine
compartment.

License plate lamps
Each license plate bulb is accessible after removing the relevant lens. The license plate lamps can be accessed following
removal of the trunk lid liner and upper trim finisher.
Rear lamp assembly
Each rear lamp assembly incorporates a stop/tail lamp, a fog lamp, a reversing lamp and a direction indicator lamp. Access
for bulb replacement is from the trunk.
Side markers
Each side marker is retained in the bumper cover by a lug on one end of the unit and a spring clip at the other end. The unit is not electrically connected for all markets.
High mounted stop lamp
The high mounted stop lamp (HMSL) is secu red to studs on the center lower edge of the backlight and provides illumination
using five bulbs.
Operation
All lamps are controlled by the BPM which pr ovides an appropriate output in response to an input received when a selected
switch is operated.
The side marker lamps receive an input from the BPM via relay 3 and fuse F21. The license plate lamps receive an input
from the BPM via relay 3 and fuse F19. The rela y and fuses are located in the trunk fuse-box.
The tail lamps receive an input direct from the BPM.
The stop, reversing and rear fog lamps are controlled by the security and locking module (SLM) which receives inputs via
the SCP network from the BPM.
The HMSL is not controlled by the SLM; it receives input from the brake switch via relay 5 and fuse F8 in the trunk fuse-box.

The BPM and SLM monitor the stop lamps (n ot HMSL) and tail lamps for failure.
Fault analysis must be undertaken using the PDU, refer to Diagnosis and Testing.
Consult the relevant Electrical Guid e for details of circuit operation.

Diagnosis and Testing
Tests Using the Portable Diagnostic Unit
Refer to PDU User Guide
The complexity of the electronics involved with the various Electronic Control Modules and the multiplexed communication
networks, preclude the use of workshop general electrical test equipment. Therefore, reference should be made to the PDU
User Guide for detailed inst ructions on testing the exterior lamps and circuits.
The PDU systematically tests and analyses the lamp assemblies, the bulbs and the electrical connections to them. It should
be noted that the lamps are not wired direct ly to the switches. Actuation of a switch provides an input signal to the Body
Processor which interpre ts the signal as a request to switch output from the Bo dy Processor, either directly or indirectly to a
specific lamp.
Where a fault involving a lamp is indicated by the PDU, befo re replacing the component, some basic diagnostic methods
may be necessary to confirm that connections are good and that wiring is not damaged.
