System Operation CENTRAL JUNCTION BOX (CJB) AND REAR JUNCTION BOX (RJB)
The CJB is an integrated unit which controls body functions and power distribution. The CJB is located on the RH 'A' pillar. The RJB also controls body functions and power distribution and is located in the RH side of the luggage compartment. Central Junction Box

The CJB receives inputs from the following switches via the instrument cluster and the medium speed CAN bus: LH Steering column multifunction switch - Side lamp position
- Headlamp position
- Automatic (AUTO) position
- Timer delay positions
- Turn signal indicators
- Headlamp flash and main beam positions.
The CJB receives direct inputs from the following components: Stop lamp switch
Rain/light sensor.
The CJB provides power supplies to the following lamps:
LH and RH front side lamps LH and RH front side marker lamps (if fitted) LH and RH static bending lamp (if fitted) LH and RH low beam headlamp LH and RH high beam headlamp. Rear Junction Box
The RJB provides power supplies to the following lamps:
LH and RH tail lamps LH and RH stop lamps LH and RH front turn signal indicators LH and RH rear turn signal indicators LH and RH licence plate lamps LH and RH side marker lamps High mounted stop lamp
Rear fog lamps
Reverse lamps.

The RJB also provides a power supply to the LH and RH door modules. The door modules use the power supply to activate the turn signal indicator side repeater lamps located in the door mirrors, on receipt of a medium speed CAN bus message from the RJB. Circuit Protection

The CJB and the RJB provide circuit protection for their respective lighting circuits. The exterior lighting circuits are protected

by Field Effect Transistors (FET's). The FET's can detect overloads and short circuits and respond to heat generated by
increased current flow caused by a short circuit.

On a normal conventionally protected circuit this would cause a fuse to blow. The FET's respond to the heat increase and
disconnect the power supply to the affected circuit. When the fault is rectified or the FET has cooled, the FET will reset and
operate the circuit normally. If the fault persists the FET will cycle, disconnecting and reconnecting the power supply.

The CJB and the RJB store fault codes which can be retrieved using a Jaguar approved diagnostic system. The fault code will identify that there is a fault on a particular output circuit which will assist with fault diagnosis and detection.
Alarm Indications

The exterior lighting system is used for alarm arm and disarm requests to show alarm system status.

When the driver locks and arms the vehicle, a visual indication of a successful lock and arm request is displayed to the driver
by a single flash of the hazard flashers. If the vehicle is superlocked, then the hazard flashers will flash a second time (200 ms
off and 200 ms on) to confirm the superlock request.

If the alarm is activated, the hazard flashers are operated for 10, 30 second cycles of 200 ms on and 200 ms off, with a 10
second delay between each cycle.


NOTE: On North American Specification (NAS) vehicles, the delay between the cycle when the alarm is activated is 60
seconds.
Lights on Warning

When the ignition is in the off power mode 0 or accessory power mode 4 and the lighting control switch is in the side lamp or
headlamp position, a warning chime will sound if the driver's door is opened. This indicates to the driver that the exterior
lights have been left switched on.

The chime is generated from the instrument cluster sounder on receipt of a lights on signal, a driver's door open signal and an
ignition off power mode 0 or accessory power mode 4 signal via a medium speed CAN bus signal from the CJB. Headlamp Timer

The RJB controls the headlamp timer function which allows the headlamps to remain on for a period of time after leaving the vehicle. This is a driver convenience feature which illuminates the driveway after leaving the vehicle.

To operate the timer function the lighting control switch must be in one of the three headlamp timer positions when the
ignition status is changed from ignition on power mode 6 to the off power mode 0. The timer function will then be initiated and
the low beam headlamps will be illuminated for the selected timer period.


NOTE: If the lighting switch is in the AUTO position, the headlamp timer will not function when the ignition is changed to
off power mode 0.

When the lighting control switch is in the autolamp exit delay position, the lighting control switch 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 RJB that autolamps has been selected.
Depending on the selected exit delay position, the reference voltage to the autolamp exit delay switch is routed through 3, 2
or 1 resistors which is detected by the instrument cluster. The cluster outputs a message on the medium speed CAN bus to the RJB that autolamp exit delay period has been selected at 30, 60 or 120 seconds respectively. Crash Signal Activation

When a crash signal is transmitted from the RCM (restraints control module), the RJB activates the hazard flashers. The hazard flashers continue to operate until the ignition is in the off power mode 0 or accessory power mode 6. Once this ignition state
has occurred, the RCM will cease to transmit the crash signal.
LIGHTING CONTROL SWITCH

The instrument cluster outputs 2 reference voltages to the rotary lighting control switch; one feed being supplied to the light
selection function of the switch and the second feed being supplied to the auto headlamp exit delay function. The switch
position is determined by instrument cluster by the change in returned signal voltage which is routed through up to 4 resistors
in series depending on the selection made.

OFF - When the lighting control switch is in the off position, the reference voltage flows through 1 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 that no lighting selection is made. 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.

SIDE LAMPS - When the lighting control switch is in the side lamp position, the reference voltage flows through 2 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 side lamps. 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 or exit delay has not been selected.
HEADLAMPS - When the lighting control switch is in the headlamp position, the reference voltage flows through 3 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 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.



EXTERIOR BULB TYPE/RATING Component Description

The following table shows the bulbs used for the exterior lighting system and their type and specification.


NOTE: The tail lamps, side marker lamps, stop lamps, high mounted stop lamp and rear fog lamps are illuminated by
LED's and are non-serviceable components.

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.

Halogen Low/high Beam Headlamp

The halogen low/high beam headlamp uses a projector lens, similar to the xenon 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. The low/high beam
bulbs are quartz halogen and 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.
Halogen High Beam Headlamp - Xenon and Halogen
The xenon and halogen headlamps use a complex surface reflector for the halogen fill in high beam lamp only lighting unit,
which is of the same design on both headlamp types. This type of reflector has the reflector divided into separate parabolic
segments, with each segment having a different focal length.

The high beam headlamp bulbs are quartz halogen and are retained in the headlamp unit with conventional wire retaining
clips.
Cornering Lamps


NOTE: The cornering lamps are not fitted to NAS 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 headlamp assembly and shares the same housing as the low beam headlamp. The cornering lamp
uses a 35W Halogen H8 bulb which is permanently located in an integral 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
on the base of the headlamp housing.

The cornering lamps are controlled by the LH steering column multifunction switch with the lighting control switch in the headlamp position and the ignition in power mode 6. The cornering lamps are supplied power via the ignition circuit 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 vice versa, providing the vehicle speed and lighting control switch
positions are correct.
Static Bending Lamps


NOTE: The static bending lamps are not fitted to NAS vehicles.

The static bending lamps are designed to illuminate the direction of travel when cornering at low speeds. The static bending
lamp functionality, which is controlled by the CJB and the headlamp leveling module, operates using inputs from the steering angle sensor and vehicle speed information from the ABS (anti-lock brake system) module. The static bending lamp is
incorporated into the headlamp assembly and shares the same housing as the low beam headlamp. The design of the lens
projects a spread of light from the vehicle at approximately 45 degrees to the vehicle axis. The static bending lamp uses a
35W Halogen H8 bulb which locates in a holder which is connected via wires to the main connector 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 static bending lamps operate with a steering angle sensor CAN bus signal which is received by the CJB. The CJB monitors this signal and vehicle speed and activates the static bending lamp bulb. When the operation parameters of the lamp are
reached, the CJB fades the static bending lamp bulb on using a PWM (pulse width modulation) voltage over a period of approximately 2 seconds. When the lamp is switched off, the CJB fades the bulb off by decreasing the PWM voltage in a linear manner depending on steering angle and vehicle speed. The cornering lamps can only be active for a maximum of 3 minutes.


NOTE: Static bending lamps only operate when the transmission is in DRIVE or in SPORT.

Turn Signal Indicators

The turn signal indicator lamp is incorporated into the outer part of the headlamp assembly. The turn signal indicator lamp
uses a PY21W bayonet orange colored bulb in ROW markets, a S8W 27/7W wedge bulb is used in NAS markets. The bulb is
fitted into a holder which connects with contacts in the headlamp housing. The holder is fitted into an aperture in the
headlamp housing and rotated to lock into position.

When active, the turn signal indicator 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 Lamps

The side lamp is located between the headlamp projector module and the high bean headlamp. The side lamp uses a W5W
wedge fitting bulb which locates in a holder which 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 by removal of the inner cover on the rear
of the headlamp housing. Access to the bulb requires removal of the headlamp from the vehicle. The side lamps are operated
by selecting side lamps or headlamps on the lighting control switch. The side lamps are functional at all times and are

dependant on a particular ignition mode status. 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 Side Marker Lamps (NAS only)

The side marker lamp is located in the outer part of the headlamp assembly. The side marker lamp uses a W5W wedge fitting
bulb. The bulb is fitted into a holder which connects with contacts in the headlamp housing. The holder is fitted into an
aperture which connects with contacts in the headlamp housing. The side marker lamp is active at all times when the side
lamps are active.

AUTOMATIC HEADLAMP OPERATION

The automatic headlamp function is a driver assistance system. The driver can override the system operation by selection of
side lamp or headlamp on if the ambient light conditions require front and rear lighting to be active. The automatic headlamp
system uses a light sensor and the CJB, which are connected via a LIN (local interconnect network) bus to control the headlamp functionality. The light sensor is incorporated in the rain/light sensor located on the inside of the windshield, below
the rear view mirror. The wiper system also uses the rain/light sensor for automatic wiper operation.

The light sensor measures the ambient light around the vehicle in a vertical direction and also the angular light level from the
front of the vehicle. The rain/light sensor uses vehicle speed signals, wiper switch position and the park position of the front
wipers to control the system. The automatic headlamp operation uses ambient light levels which are monitored by photodiode
incorporated in the rain/light sensor. The rain/light sensor sends a lights on/off request to the CJB on the LIN bus, which responds by switching on the low beam headlamps, front side lamps and rear tail lamps. The automatic headlamps are
activated under the following conditions:

Twilight
Darkness
Rain
Snow
Tunnels
Underground or multistoried car parks.

Operation of the automatic headlamps requires the ignition to be in ignition mode 6, the lighting control switch to be in the
'AUTO' position and a lights on request signal from the light sensor. If the rain sensor signal activates the fast speed wipers,
the low beam headlamps are activated, providing the lighting control switch is in the 'AUTO' position.

HEADLAMP LEVELING

Headlamp leveling provides for the adjustment of the vertical aim of the headlamps. The leveling system is primarily required
to minimise glare to other road users when a heavy load is in the rear of the vehicle. Two systems of headlamp leveling are
available; manual and static dynamic.
Manual Headlamp Leveling

The manual system uses a thumbwheel rheostat to adjust the vertical alignment of the headlamps to compensate for differing
vehicle loading. The rotary thumbwheel is located on the auxiliary lighting switch, adjacent to the illumination dimmer
thumbwheel. Three positions are available to adjust the headlamps to a position to prevent glare to other road users.
Static Dynamic Headlamp Leveling
The static dynamic headlamp leveling system uses the following components:
Front and rear vehicle height sensors
Two headlamp leveling, vertical adjustment motors
Headlamp leveling module
Ignition in mode 6
Vehicle speed information from ABS module.
The static dynamic system uses height sensors fitted to the front and rear suspension and a headlamp leveling module which
periodically monitors the vehicle attitude and adjusts the headlamp vertical alignment accordingly.

Static dynamic headlamp leveling is controlled by a headlamp leveling module located in the lower instrument panel, behind
the glovebox.

The height sensors are both located on the RH side of the vehicle. The front sensor is attached to the front suspension lower arm with a strap and to the front sub frame with a bracket and 2 bolts. The rear sensor is attached to the rear suspension
upper control arm with a cable tied clip and to the rear sub frame with a bracket and 2 bolts. Each sensor has 3 connections to
the headlamp leveling module; power, ground and signal.

DAYTIME RUNNING LAMPS (DRL)

Refer to DRL section for details. Refer to: Daytime Running Lamps (DRL) (417-04 Daytime Running Lamps (DRL), Description and Operation).
REAR LAMP ASSEMBLY

The rear lamp assembly is a 2 piece unit, with one part located in the rear quarter panel and the second part attached to the
luggage compartment lid. The outer rear lamp assembly is located in a recess in the vehicle body. The lamp is secured with 2
studs inboard studs on the lamp body which are secured to the vehicle body with 2 nuts. A third outboard stud and nut secures

1 Nut (3 off) 2 Reverse lamp bulb and holder 3 Rear lamp electrical connector 4 Turn signal indicator bulb and holder 5 Securing clip 6 Rear fog lamp electrical connector 7 Rear fog lamp LED's and Printed Circuit Board (PCB) 8 Side marker LED's (4 off - all markets) 9 Reverse lamp 10 Turn signal indicator lamp 11 Side lamp/stop lamp LED's (24 off) 12 Rear fog lamp LED's (3 off) Rear Stop and Side Lamp

The turn signal indicator, side and stop lamps and reverse lamps are located in each outer rear lamp assembly. The side lamps
and stop lamps use 24 LED's. The 24 LED's are illuminated at a higher intensity than the side lamp when the stop lamp switch is operated by pressing the brake pedal. A side marker lamp is fitted to the outer rear lamp assembly and is fitted in all
markets. The side marker lamp also uses 4 LED's and are active at all times when the side lamps are selected on.
The stop lamps can also be activated by the adaptive speed control system. A signal from the adaptive speed control module
is sent via the high speed CAN bus to the RJB which activates the stop lamps until an off message is received. Turn Signal Indicator

The turn signal indicator lamp uses a Phillips Hypervision glass filament bulb. The bulb is located in a holder which has
contacts which mate with contacts on lamp body. The holder locates in the lamp body and is rotated to lock.

If a bulb fails, the remaining turn signal indicator lamps continue to flash at the normal speed. The applicable turn signal
indicator in the instrument cluster will flash at double speed to indicate the bulb failure to the driver. www.JagDocs.com
