The lighting system has an 'auto' lights function which is controlled by the CJB on receipt of signals from the rain/light sensor located at the top of the windscreen. The exterior lights are turned on or off in response to ambient light signals from the
rain/light sensor on a LIN (local interconnect network) bus connection to the CJB . The auto lights can also be activated when the windshield wipers are activated by signals from the rain sensor, which is located at the top of the windshield or when the
driver activates the wipers in the fast wipe position.

Two levels of headlamp specification are available; halogen or xenon. In certain markets the headlamps feature a cornering
lamp or a static bending lamp which illuminates the area at the side of the vehicle when turning into driveways for example.
North American Specification (NAS) vehicles have a side marker lamp installed in the headlamp assembly. Replacement of any
of the headlamp bulbs requires removal of the headlamp assembly.

The tail lamp comprises two separate lamp assemblies. The turn signal indicator, side and stop lamps and reverse lamps are
located in each rear fender tail lamp assembly. The rear fog lamps are located in separate units attached to the luggage
compartment lid. A side marker lamp is fitted to the rear fender tail lamp assembly and is fitted in all markets.

Two systems of headlamp leveling are available; manual leveling which is only available on halogen headlamps and static
dynamic leveling which is available on xenon headlamps. The manual system uses a thumbwheel rheostat to adjust the
vertical alignment of the headlamps to compensate for differing vehicle loading. 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.

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
