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.

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

Interior Lighting - Interior Lighting - Overview
Description and Operation

OVERVIEW Published: 11-May-2011

Interior lighting is provided to enable the safe entry and departure from the vehicle for the driver and passengers in low
ambient light conditions, without any manual switching of the lights.


NOTE: The term interior lamps also includes the door mirror approach lamps.

The interior lamps are controlled by the CJB (central junction box) and the RJB (rear junction box) and have 2 modes of
operation: manual and automatic. The front interior lamps in the front overhead console are operated using the 'JaguarSense'
system. The system uses capacitive proximity sensor technology for the switch operation which is integral with the overhead
console. The rear overhead console interior lamps have conventional switches.

In the manual mode the interior lamps can be switched on and off with the JaguarSense system. Positioning your hand
adjacent to each lamp in the front overhead console will switch interior lamps on or off and completely disable the interior
lamp system. In the automatic mode the interior lamp functionality is controlled by the CJB and the RJB and reacts to the vehicle being locked or unlocked and opening the vehicle doors.

In manual mode the interior lamps can be operated by placing your finger(s) close to, or touch, the surface of the appropriate
lamp. The courtesy light and map reading lamps can be operated manually by the 'JaguarSense' system. When in automatic
mode, the courtesy lamp functionality is also controlled by the CJB and the RJB and reacts to the vehicle being locked or unlocked and opening the vehicle doors. To deactivate or activate automatic illumination, touch the front courtesy lamp for
approximately 2 seconds

The driver's and passenger door approach lamps are controlled by the driver's door module and the passenger door module
respectively and operate with the automatic mode. The door modules receive a power supply from the RJB and receive information to illuminate the approach lamps on the medium speed CAN (controller area network) bus from the RJB and the CJB. www.JagDocs.com
