Xenon/Halogen Headlamp Beam Comparison Bi-XenonAHalogenB The xenon low/high beam headlamps use ellipsoidal technology for the lens and reflector providing improved night time visibility compared to conventional halogen headlamps. The xenon headlamps provide the following benefits when compared to halogen headlamps: •Longer bulb life - Approximately 3 to 5 times longer than a halogen bulb •Increased light output - xenon headlamps output 3 to 4 times more light on the road surface than halogen headlamps •Blue/White light which is closer to natural daylight - xenon lamps produce a blue/white light compared to a yellow light produced by a halogen bulb •Improved night time driving visibility - xenon lamps produce a wider and brighter beam in front of the vehicle than conventional halogen bulbs •Lower running temperatures •Lower power consumption.

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 as an assembly is known as the projector module. The reflector is curved and provides the mounting for the xenon bulb. The bulb locates in a keyway to ensure correct alignment in the reflector and is secured by pushing and turning to lock. The bulb has a two pin connector which is also a push and turn to lock fitting. The shutter controller is a solenoid which operates, via a lever mechanism, to the shutter. The shutter is used to change the beam projection from low beam to high beam and visa versa. A tourist lever mechanism is located on the right hand side of the projector module. This mechanism moves 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 reflector. Make sure that the headlamps are off before removing the access cover. The xenon bulbs illuminate when an arc of electrical current is established between two electrodes within the bulb. The xenon gas sealed in the bulb reacts to the electrical excitation and the heat generated by the current flow. The xenon gas reaction to the controlled current flow between the electrodes produces the blue/white light. To operate at full efficiency, the xenon bulb goes through three stages of operation before full output for continuous operation is achieved. The three 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 18000 to 28000 volts to establish the arc. This is produced by the igniters. The warm-up phase begins once the arc is established. The xenon control modules regulate the supply to the bulbs 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 stabilises ensuring a continual current flow between the electrodes. When the warm-up phase is complete, the xenon control modules change to continuous phase. The supply voltage to the bulb is reduced and the operating power required for continual operation is reduced to 35W. The xenon system is controlled by the CJB, the two xenon control modules and the two igniters. 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 regulated power supply from the control modules. Turn Signal Lamp The turn signal lamp is incorporated into the outer part of the headlamp assembly. The lamp is located above the side lamp/cornering lamp. The turn signal lamp uses an 27W/7W S8W wedge bulb. The bulb is fitted into a holder which is connected via wires to the main connector on the headlamp housing. The holder is fitted into an aperture in the headlamp housing and rotated to lock into position. The bulb is accessible via a sealed cover which is attached to the rear of the headlamp housing. The cover is secured in the housing by rotating in a clockwise direction until locked. Access to the cover requires removal of the headlamp from the front carrier assembly and removal of the outer locking plate from the headlamp. (G421288) Technical Training174 Lesson 2 – ElectricalExterior Lighting
The turn signal lamps are operated by the left hand steering column multifunction switch or by the hazard flasher switch. The steering column multifunction switch is only active with the ignition switch in the ignition position (II), the hazard flasher switch is active at all times. When active, the turn signal lamps will flash at a frequency cycle of 380ms on and 380ms off. If a bulb fails, the remaining turn signal lamps bulbs continue to flash at normal speed. The turn signal indicators in the instrument cluster will flash at double speed to indicate the bulb failure to the driver. Side Lamp The side lamp is incorporated into the outer part of the headlamp assembly and is located below the turn signal indicator lamp. The side lamp shares the same housing and reflector as the cornering lamp and static bending lamp (when fitted). The side lamp uses a 5W bayonet fitting bulb which locates into a holder which is connected via wires to the main connector on the headlamp housing. The holder is a push fit into a receptacle in the headlamp housing. The bulb is accessible via a removable cover at the rear of the headlamp housing. Access to the cover requires removal of the headlamp from the front carrier assembly and partial removal of the outer locking plate from the headlamp. The side lamps are operated by selecting side lamps or headlamps on the lighting control switch. The side lamps are operational at all times and are not dependant on the ignition switch position. The side lamps will also be illuminated when the lighting control switch is in the AUTO position and a lights on signal is received by the CJB from the rain/light sensor. Cornering Lamp NOTE: The cornering lamps are not fitted to NAS market vehicles The cornering lamps are an optional feature designed to illuminate the direction of travel when cornering at low speeds. The design of the lens projects a spread of light from the vehicle at approximately 45 degrees to the vehicle axis. The cornering lamp is incorporated into the outer part of the headlamp assembly and shares the same housing and reflector as the side lamp. The cornering lamp uses a 35W Halogen H8 bulb which locates in a holder which is connected on the headlamp housing. The holder is located in an aperture in the headlamp housing and rotated to lock. The bulb is accessible via a removable cover at the rear of the headlamp housing. The cornering lamps are controlled by the left hand steering column multifunction switch with the lighting control switch in the headlamp position and the ignition switch in position II. The cornering lamps are supplied power via the ignition switch to ensure that they do not function with the headlamp delay feature. The cornering lamps are deactivated if the vehicle speed exceeds 25 mph (40 km/h). Only one cornering lamp will illuminate at any one time. If the left hand turn signal indicators are selected on, the left hand cornering lamp will be illuminated and visa versa, providing the vehicle speed and lighting control switch positions are correct. Cornering lamps are disabled when reverse gear is selected. Exterior LightingLesson 2 – Electrical 175Technical Training (G421288)

Turn signal lamp access cover (hidden)12 The AFS is a new system to improve driver visibility under differing driving conditions. AFS provides a larger visible area which is illuminated when cornering by adjusting the position of the beam distribution on the road. Horizontal adjustment is made automatically to the most suitable orientation for the driving conditions using steering angle and information from other vehicle sensors. AFS is only available with xenon headlamps and also includes the dynamic headlamp levelling system described in the Headlamp Levelling section of this document. The bi-xenon module within the headlamp is controlled by actuator motors which rotate the projector module on its vertical and horizontal axes to adjust the beam output to suit the cornering conditions and vehicle inclination. Only the bi-xenon lamp projector module swivels, the halogen high beam lamp unit remains static. The AFS system is controlled by an AFS control module which is located at the bottom of the A pillar, behind the CJB. The control module controls the vertical and horizontal alignment of the xenon projector module and the operation of the static bending lamp which is requested by the AFS control module but controlled by the CJB. AFS Concept Conventional headlamp beam distribu- tion A AFS swivel headlamp beam distributionB AFS Control Module The AFS control module is a dual functionality unit which also incorporates software to control the dynamic headlamp levelling. The AFS control module is connected to the high speed CAN bus and receives inputs from other vehicle systems on the status of the following parameters: Exterior LightingLesson 2 – Electrical 177Technical Training (G421288)
•Steering angle •Vehicle speed •Headlamp status •Engine running •Reverse gear selected •Automatic lighting on. The AFS will only operate when the AFS control module receives an engine running signal on the CAN bus. When the engine running signal is received and the lighting control switch is in the headlamps position, the AFS control module performs an initialisation routine. The AFS will also function when the lighting control switch is in the AUTO position and the AFS control module receives a lights on signal from the rain/light sensor and an engine running signal. The AFS control module then monitors the inputs from the other vehicle systems to control the AFS functionality according to cornering angles and vehicle speed.

Manoeuvring mode is used for speeds up to 18.6 mph (30 km/h). Manoeuvring mode only moves the xenon projector module on the side of the vehicle towards the direction of turn, e.g. Left hand projector module moves to the left during a left hand turn. The opposite projector module is fixed and does not move. This mode allows the maximum amount of swivel range of the projector module to 15 degrees. Normal driving mode is used for speeds between 18.6 and 43.5 mph (30 and 70 km/h). Normal driving mode moves both xenon projector modules at a ratio of 3:1, e.g during a left hand turn, the left hand projector module moves 3 degrees and the right hand projector module moves 1 degree. This mode allows the maximum amount of swivel range of the projector module in the direction of the turn to 12 degrees. High speed mode is used for speeds above 43.5 mph (70 km/h). High speed mode moves both xenon projector modules at a ratio of 3:1, e.g during a left hand turn, the left hand projector module moves 3 degrees and the right hand projector module moves 1 degree. This mode allows the maximum amount of swivel range of the projector module in the direction of the turn to 10 degrees. Reverse mode disables the swivel function when reverse gear is selected. The AFS projector modules move to their central straight ahead position and the static bending lamp, if active, will go off. When reverse gear is deselected, the AFS projector modules will move to a position to match the steering angle and the static bending lamp will illuminate if the operating conditions are correct (i.e. vehicle speed above 1.86 mph (3 km/h).

The AFS assembly contains an additional carrier frame which provides the location for the AFS components. The remaining lamps are as described previously for the Xenon headlamp assembly. The functionality of the static bending lamp on the AFS headlamp is different from the functionality of the cornering lamp on the xenon headlamp. The carrier frame has a radial bearing at the top and a thrust washer at the bottom which provide the horizontal pivot points for the xenon projector module. The lamp module lower pivot has a splined end which locates in the mating splines of the AFS horizontal actuator motor. The carrier frame is suspended on two flexible mountings at the top which provide for the vertical pivot points for the xenon projector module which allow for the vertical adjustment of the projector module. The bottom of the carrier frame is attached to the AFS vertical actuator motor. The AFS actuator motors are dc motors which are driven by a power output from the AFS control module. The AFS control module also provides the earth path for the motor. The actuators contain a potentiometer which is connected via wires with gold plated connector pins to the AFS control module. The two wires to each actuator provide a feedback signal to the AFS control module to give the precise position of the xenon projector module. The AFS control module receives front and rear suspension height data to provide dynamic headlamp levelling adjustment via the vertical actuator motor. The AFS control module also receives vehicle speed signals from the ABS module to adjust the projector module vertically to increase the beam range as the vehicle speed increases. Initialisation Procedure When the AFS control module receives an ignition on signal, the control module performs the initialisation procedure which ensures that the headlamps are correctly aligned on both their vertical and horizontal axes. The headlamp levelling initialisation takes less than 3 seconds to complete. The headlamp levelling motors are powered from their current position, which can be either the upper or lower limit or somewhere in between, to their lower position and then back to the 0 degrees position. The AFS swivel initialisation starts less than 1 second after the headlamp levelling initialisation is activated to ensure that the headlamps are at or below the 0 degree position in the vertical axis, thus preventing glare to oncoming vehicles. The AFS swivel initialisation is completed in less than 2.5 seconds. The LH and RH AFS actuator motors are powered from the 0 degree position to their fully inboard position, then to their fully outboard position and then back to the 0 degree position.
