resistors. The returned signal voltage is detected by the instrument cluster which outputs a message on the medium speed
CAN bus to the CJB to activate the headlamps. The reference voltage to the auto headlamp exit delay switch is routed through 4 resistors which is detected by the instrument cluster which outputs a message on the medium speed CAN bus to the CJB that auto headlamp or exit delay has not been selected.
AUTOLAMPS - When the lighting control switch is in the auto headlamp position, the reference voltage flows through 4 of the
resistors. The returned signal voltage is detected by the instrument cluster which outputs a message on the medium speed
CAN bus to the CJB to activate the autolamp function. The reference voltage to the autolamp exit delay switch is routed through 4 resistors which is detected by the instrument cluster which outputs a message on the medium speed CAN bus to the CJB that auto headlamp has been selected.
AUXILIARY LIGHTING SWITCH
Headlamp Leveling Rotary Thumbwheel (Halogen headlamps only)
A power supply is passed to the headlamp leveling thumbwheel from the ignition relay in the EJB. Depending on the position of the thumbwheel, the voltage passes through 1, 2 or 3 resistors connected in series. The voltage through the resistors is
passed to the headlamp leveling motor controller in each headlamp. The received voltage is determined as a request for the
appropriate level position and the controller powers the headlamp level motors to the applicable position for each headlamp.
Rear Fog Lamp Switch
The instrument cluster supplies a reference voltage and return to the rear fog lamp switch. The fog lamp switch is a
non-latching, momentary switch.
When the fog lamp switch is off the reference voltage is passed through a 1Kohm resistor. The voltage through the resistor is
returned to the instrument cluster that determines that no request for fog lamp operation has been made.
When the driver presses the fog lamp switch, the reference voltage is passed through a 330 ohm resistor. The change is return
voltage is sensed by the instrument cluster which determines fog lamp operation has been requested. The instrument cluster
transmits a medium speed CAN bus signal to the RJB providing the lighting control switch is in the correct position. The RJB reacts to the message and provides a power supply to the 3 LED (light emitting diode)'s in each rear fog lamp. A fog lamp
warning lamp in the instrument cluster will also be illuminated when the fog lamps are operating.
The RJB will only activate the rear fog lamps if the headlamps are selected on or are active with auto headlamp activation. When the headlamps are turned off the fog lamps are also turned off. When the headlamps are next switched on, the fog
lamps will not be activated until the driver requests fog lamp operation.
NOTE: The fog lamps do operate when DRL (daytime running lamps) are active.
HEADLAMP LEVELING
Manual Headlamp Leveling - Halogen headlamps only
A power supply is passed to the headlamp leveling motor in each headlamp from the ignition relay in the EJB. When a signal voltage is received from the headlamp leveling rotary thumbwheel, the headlamp leveling motor controller in each headlamp
uses the power supply to operate the motors and move the headlamp to the requested position.
Static Dynamic Headlamp Leveling - Xenon headlamps only
The headlamp leveling module receives a power supply from the ignition relay in the EJB. The same power supply is also supplied to the headlamp leveling motor in each headlamp assembly. The front and rear height sensors are connected to the
headlamp leveling module and receive a power and ground from the module. Each sensor has a signal line to the headlamp
leveling module to return height information to the module. The module uses the height signals from the sensors to calculate
the vehicle attitude and supplies a signal to each motor to power the headlamp to the required position.

The bi-xenon headlamp uses a projector lens, similar to the halogen headlamp. The projector module comprises an ellipsoidal
lens and a reflector. The projector reflector collects the light produced by the halogen bulb and projects the light into a focal
plane containing a shield. The contour of the shield is projected onto the road by the lens. A complex surface reflector is used
for the halogen fill in high beam lamp. This type of reflector is divided into separate parabolic segments, with each segment
having a different focal length. The low and high beam bulbs are quartz halogen H7, with a rating of 55W. The bulbs are
retained in the headlamp unit with conventional wire retaining clips.
A tourist lever mechanism is located on the right hand side of the projector module. This mechanism moves a flap to blank off
a portion of the beam spread to enable the vehicle to be driven in opposite drive hand markets without applying blanking
decals to the headlamp lens. The beam is changed by removing the access cover at the rear of the lamp assembly and moving
a small lever located near the bulb holder, at the side of the projector.
NOTE: The tourist lever is not fitted to NAS vehicles.
WARNING: The Xenon system generates up to 30000 volts and contact with this voltage could lead to fatality. Make sure
that the headlamps are switched off before working on the system.
The following safety precautions must be adhered to when working on the xenon low beam headlamp system:
DO NOT attempt any procedures on the xenon headlamps when the lights are switched on.
Handling of the D1S xenon bulb must be performed using suitable protective equipment; for example gloves and
goggles. The glass part of the bulb must not be touched.
Xenon bulbs must be disposed of as hazardous waste.
Only operate the bulb in a mounted condition in the projector module installed in the headlamp.
The xenon headlamp is known as 'bi-xenon' because it operates as both a low and high beam headlamp unit. The xenon lamp,
or High Intensity Discharge (HID) lamp as they are sometimes referred to, comprises an ellipsoidal lens with a solenoid
controlled shutter to change the beam output from low to high beam.
NOTE: If the lighting control switch is in the 'off' position, both the xenon lamp and the halogen high beam lamp will
operate when the high beam 'flash' function is operated.
The xenon headlamp system is controlled by the CJB using a control module for each headlamp and an igniter. The control modules and the igniters provide the regulated power supply required to illuminate the bulbs through their start-up phases of
operation.
The xenon headlamp is a self contained unit located within the headlamp assembly. The unit comprises a reflector, an adaptor
ring, the lens, a shutter controller and the xenon bulb, which together forms an assembly known as the projector module. The
reflector is curved and provides the mounting point for the xenon bulb. The bulb locates in a keyway to ensure the correct
alignment in the reflector and is secured by a plastic mounting ring. The bulb is an integral component of the igniter and is
electrically connected by a connector located in the igniter unit.
The shutter controller is a solenoid which operates the shutter mechanism via a lever. The shutter is used to change the beam
projection from low beam to high beam and vice versa.
The xenon bulbs illuminate when an arc of electrical current is established between 2 electrodes within the bulb. The xenon
gas sealed in the bulb reacts to the electrical excitation and the heat generated by the current flow to produce the
characteristic blue/white light.
To operate at full efficiency, the xenon bulb goes through 3 full stages of operation before full output for continuous operation
is achieved. The 3 phases are; start-up phase, warm-up phase and continuous phase.
In the start-up phase, the bulb requires an initial high voltage starting pulse of up to 30000 volts to establish the arc. This is
produced by the igniter. The warm-up phase begins once the arc is established. The xenon control module regulates the supply
to the bulb to 2.6A which gives a lamp output of 75W. During this phase, the xenon gas begins to illuminate brightly and the
environment within the bulb stabilizes, ensuring a continual current flow between the electrodes. When the warm-up phase is
complete, the xenon control module changes to continuous phase. The supply voltage to the bulb is reduced and the operating
power required for continual operation is reduced to 35W. The process from start-up to continuous phase is completed in a very
short time.
The xenon control modules (one per headlamp) receive an operating voltage from the CJB when the headlamps are switched on. The modules regulate the power supply required through the phases of start-up.
The igniters (one per headlamp) generate the initial high voltage required to establish the arc. The igniters have integral coils
which generate high voltage pulses required for start-up. Once the xenon bulbs are operating, the igniters provide a closed
circuit for the regulated power supply from the control modules.

Wiring Harnesses - Wiring Harness
Description and Operation
Introduction Published: 21-Jan-2014
CAUTION: Do not use any other heat shrink sleeve other than the approved glue lined heat shrink sleeve mentioned in
the repair procedure.
The purpose of this document is to promote quick and efficient minor repair to harness connectors or cables using approved
methods. Repairs may only be made to cables and connectors which have been mechanically, not electrically damaged. It also
applies where the whole extent of the damage can be clearly identified and rectified.
Care and neatness are essential requirements in making a perfect repair.
Caution:
This harness repair guide, does not approve repairs to any of the following circuits:
1. Any media orientated system transport network harnesses.
2. Supplement restraint system (SRS) firing circuits (Air bags).
3. Link lead assembles, which are unique to safety critical circuits such as anti-lock brake system (ABS) and thermocouple
circuits. An example of this is the ABS wheel speed sensors with moulded connectors.
4. 4. Screened cables, leads and wiring harness(s).
If any harness(s) with defective electrical connector terminals or wires from the above circuits are a concern, new
components must be installed.
Repair Components
CAUTION: Where the repair procedure indicates that a glue lined heat shrink sleeve should be applied, apply sufficient
heat to the glue lined heat shrink to melt the glue in order to provide a water tight seal. Do not over heat the glue lined heat
shrink sleeve so that the wiring harness insulation becomes damaged.
The wiring harness repair components comprises:
Pre-terminated wiring harness(s) of different sizes and types
Three sizes of butt splice connectors
A selection of colored cable identification sleeves
Two sizes of glue lined heat shrink sleeves
A suitable heat source, for shrinking heat shrink sleeves will be required.
The pre-insulated diamond grip range of electrical connector terminals and in-line, butt splice connectors are the only
acceptable product for the repairs of wiring harnesses. The butt connectors not only grip the wire but also the insulation,
making a very secure joint.
If an electrical connector terminal is not available approval for the repair is NOT given and in these circumstances a new wiring
harness must be installed.
Pre-Terminated Wiring Harness(s) and Butt Splice Connectors
The pre-terminated wiring harness(s) are supplied with the insulation in one of three colors, red, blue or yellow. The colors do
not apply to any particular circuit but to the harness wire size. See the Relationship Table in the Repair Method section.
Butt splice connectors are also supplied with red, blue or yellow coverings, which must be matched to the pre-terminated
wiring harness insulation color.

essential for prevention of moisture ingress that a sealed pre-terminated wiring harness must be used where a sealed terminal
was removed.
CAUTION: Where the repair procedure indicates that a glue lined heat shrink sleeve should be applied, apply sufficient
heat to the glue lined heat shrink to melt the glue in order to provide a water tight seal. Do not over heat the glue lined heat
shrink sleeve so that the wiring harness insulation becomes damaged.
Two sizes of heat shrink sleeving are available. Each heat shrink sleeve contains a sealant glue. These must be used when
connecting wiring harness(s) or electrical connector terminal(s) at all times. The smaller diameter heat shrink sleeve is to be
used with the red and blue butt splice connectors and the larger diameter sleeve with the yellow butt splice connectors.
For ease and speed, some of the pre-terminated wiring harness(s) may already have the insulation partly stripped at the splice
end. If the repair requires insulation to be stripped from the cable, refer to the Relationship Table for the correct length of
insulation to be stripped.
The Pre-Terminated Wiring Harness(s) illustration shows the electrical connector terminal type, the part number of the
pre-terminated wiring harness and the letter of the extractor tip which must be used to extract the electrical connector
terminal from the connector housing. Additionally, those electrical connector terminal(s) which are gold are identified, all
others are therefore, tinned and not gold.
Wiring Harness Cable Identification Sleeves
A selection of colored sleeves are available for maintaining the wiring harness cable identification on the pre-terminated wiring
harness. Place the correct colored sleeve(s) over the pre-terminated wiring harness insulation as near to the electrical
connector as possible with the main wiring harness cable color nearest to the electrical connector.
For example, if the original wiring harness cable color is pink with a black trace put the pink wiring harness cable identification
sleeve on the pre-terminated wiring harness first followed by a black sleeve, and slide both along the wiring harness cable to
the electrical connector terminal.

Repair Tools
The wiring harness repair tools comprises:
Crimping pliers
A wire cutter and insulation stripper
An electrical connector terminal extraction handle and tips
Extraction Handle and Tips
The extraction handle, in conjunction with the correct tip, is used to remove a terminal from an electrical connector. Each tip is
marked with an identification letter, A to K inclusive. Each tip has been specially designed to extract a particular type of
electrical connector terminal. The use of any other tool is not recommended and is liable to cause damage to the electrical
connector. The tip is fastened to the handle by a screw which holds the tip firmly yet allows it to be easily replaced.

Repair Methods
CAUTION: Several different types and sizes of terminal may be found in a single electrical connector housing.
It is necessary to identify:
The conductor (wire) size of the affected wiring harness
The electrical connector range from which the damaged wiring harness is to be removed
The terminal type
Use of the approved diagnostic tool will greatly assist in the quick identification of electrical connectors and faulty pin
terminal(s).
Reference can also be made to the vehicle Electrical Guides, held by Dealers, to identify wiring harness(s) and electrical
connector(s).
By using the Relationship Table, the wiring harness conductor (wire) size can be related to a suitable pre-terminated wiring
harness by the color of the insulation. Also, the correct length of insulation to be stripped from the wiring harness lead is
identified.

It must be noted that some electrical connector(s) have anti-backout devices which prevent the terminals from being removed
from the electrical connector. Some examples of these are shown in following illustrations. The anti-backout device must be
released before attempting to remove the terminal from the electrical connector. Some anti-backout devices require a special
tip to release the device. Most can be released by carefully using a suitable small screwdriver.
Various types of electrical connector have seals installed internally or externally to prevent moisture ingress. These normally
do not have to be removed but make sure that they are installed when the electrical connectors are connected.
The illustrations show examples of each tip used on different types of electrical connector(s). There are a large number of
different types of electrical connector used on vehicles therefore only one example using each tip is shown. Technicians
experience and judgement will dictate which type of tip should be used for those electrical connector(s) which are not shown.
Care should be exercised to avoid further damage when removing the terminals from the electrical connector.
NOTE: Examples of the extraction tips and anti-backout tips.
