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.
