Installation


13. Move the spacing bush rearward s slightly in the generator
mounting bracket, to ease fitting the new generator.
1. Position a suitable length bolt through the bush, fit a
tubular spacer or socket spanner, fit a nut and
tighten the assembly to move the bush slightly.
Remove the nut, bolt and spacer.

1. Fit the generator to the engine.
1. From above, position th e generator and fit the upper
mounting bolt and nut, but do not fully tighten.

2. Fit the generator lower mounting.
1. From below, reposition an d align the harness clip to
the generator lower mounting.
2. Fit the lower mounting bolt and nut, tighten to 38-48
Nm.
3. Connect the harness.
1. Reposition the suppres sion module harness and
connect the negative cable to the generator negative
terminal. Fit and tighten the terminal nut.

2. Secure the suppression module positive cable and
main positive cable to the generator positive
terminal.
3. Fit the boot to the terminal.
4. Reconnect the generator harness multi-plug.

4. Refit the air intake ducting to the generator. The upper section
is retained by two screws to the sump body assembly and the
lower (horizontal) section is retained by one screw.
5. Lower the vehicle on the ramp ; refer to Section 100-02.
6. Fully tighten the generator upper mounting bolt, to 18-24 Nm.

7. Refit the drive belt to the generator.
1. Pass the drive belt around the idler pulley.
2. Using spanner )Churchill JD-230 or Snap On XDHM 1415) on the centre bolt of the belt tensioner idler
pulley, rotate the adjuster against spring tension.
3. Whilst holding the tensioner against spring tension, pass the drive belt over the generator pulley and
check that it is correctly located on the other pulleys.
Release the tensioner slowly and remove the
spanner. Check the alignment of the belt.
8. Refit the fan and motor assembly ; refer to Operation 26.25.12.

9. Refit the air cleaner assembly; refer to Operation 19.10.05.
10. Reconnect the battery ground cable and fit the battery cover.
Reset the radio inform ation and the clock.

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.

2—Headlamp (main beam)
3—Front Parking (side) Lamp
4—Front Direction Indicator
5—Front Side Marker
6—Side Repeater Lamp
7—Fog Lamp

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.
