JUNCTION BOXES
Inputs System Operation
The CJB receives the following inputs which affect the operation of the interior lamps: Ignition mode
Lock/unlock
Luggage compartment lid latch switch
Door latch switches.
Outputs
The RJB outputs the following for the interior lighting system: Luggage compartment lamp power supply
Driver and passenger door module power supplies
Fade on and off grounds for front and rear overhead console interior lamps and footwell lamps
PWM (pulse width modulation) power output for the ambience lighting.
Interior Lamp Time-Out
The interior lamps are controlled by a timer within the CJB which allows a 60 second delay period for the lamps to remain active after the ignition mode has been changed to off power mode 0 or the vehicle has been unlocked. The interior lamp fade
off is controlled by the RJBvia a delayed power off relay in the CJB. The following interior lamps are subject to the delay period:
Front overhead console interior lamp
Rear interior lamps
Footwell lamps
Door mirror approach lamps.
The timer delay is activated when the CJB receives one of the following signals: An unlock signal from the Smart Key via the keyless vehicle module.
Ignition mode is changed from the crank power mode 9 or ignition power mode 6 to the accessory power mode 4 to the
off power mode 0.
If a second occurrence of the above actions occurs within the timer period, the timer will be rest and the delay period timer will
restart.
The timer delay is deactivated when the CJB receives one of the following signals: A lock signal from the Smart Key via the keyless vehicle module
Ignition mode is changed from the off power mode 0 to the accessory power mode 4 or ignition power mode 6
The CJB receives a door opened signal (even if that door is subsequently closed). Battery Saver
The battery saver provides an automatic shut-off of the interior lamps after a period of 15 minutes in order to prevent
excessive power drain on the battery.
When the ignition mode is changed from the ignition power mode 6 or accessory power mode 4 to the off power mode 0, the
CJB starts a timer which de-energizes a delayed power off relay in the CJB, removing the power supply to the interior lamps after a period of 15 minutes, switching off all or any interior lamps which have remained on for any reason.
Page 2059 of 3039
Once the timer has expired and the lamps are off, any one of the following will 'wake up' the battery saver and the interior
lamps will function again. The timer will be restarted as soon as an input is received by the CJB from one of the following:
Ignition mode changed from off power mode 0 to accessory power mode 4, ignition power mode 6 or crank power mode
9.
Any door, including the luggage compartment lid is opened
An unlock request is received from the Smart Key via the keyless vehicle module
Overhead console interior lamp is switched on via the JaguarSense function.
INTERIOR LAMPS
When the interior lighting system switches the interior lamps on, the CJB ramps the lamps up to full power over a period of 1.3 seconds. When the system switches the lamps off, after the time-out period has expired, the CJB fades the lamps off over a period of 2.6 seconds.
The interior lighting system will illuminate the interior lamps when one of the following events occurs:
The CJB receives an unlock signal from the Smart Key via the keyless vehicle module Any door is opened including the luggage compartment lid
The ignition mode is changed from ignition power mode 6 or accessory power mode 4 to off power mode 0.
The interior lighting system will turn off the interior lamps when one of the following events occurs:
Once the time-out timer delay has expired since the lamps were either activated or the last door is closed and the
vehicle is not locked
The ignition is in off power mode 0 and an external lock is requested (using either the door lock buttons or the Smart
Key) with all doors closed
The ignition mode is changed from the off power mode 0 or the accessory power mode 4 to the ignition power mode 6
The last door is closed and the vehicle is externally locked, on receipt of an unlock request from the Smart Key or door
handle operation detected when the time-out timer is still active.
DELIVERY MODE
Delivery mode is set at the factory on vehicles to minimize battery drain. The mode enables the switching off of non-critical
electrical components, including the interior lighting system. The delivery mode feature is cancelled by the dealer during the
Pre-Delivery Inspection using an approved Jaguar diagnostic system.
CRASH ILLUMINATION
When a crash signal is received from the RCM (restraints control module), the CJB activates the interior lamps once the vehicle speed has reduced to 5 km/h (3.1 mph). The hazard flashers are also activated and the doors are prevented from being locked.
The lamps remain on until the crash signal is removed, they cannot be switched off using the JaguarSense feature. The crash
signal is removed by completing one ignition on and off cycle.
INTERIOR BULB TYPE/RATING Component Description
The following table shows the bulbs used for the interior lighting system and their type and specification.
NOTE: The front overhead console and the front door ambience lighting is illuminated by LED's and are non-serviceable components.

Daytime Running Lamps (DRL) - Daytime Running Lamps (DRL) - System
Operation and Component Description
Description and Operation
CENTRAL JUNCTION BOX (CJB) System Operation
The CJB (central junction box) controls the operation of the DRL (daytime running lamps). The DRL are activated once the CJB detects an ignition on power mode 6 signal.
The CJB also monitors the lighting control switch and the auto lamps feature and overrides the DRL if required.
DAYTIME RUNNING LAMPS - CANADA Component Description
The DRL for this market use full intensity low beam headlamps. The side marker lamps, tail lamps and license plate lamps will be on, but instrument cluster illumination will be off. DRL are active when the following parameters are met:
PARK is not selected on the electronic transmission selector
Electronic Parking Brake (EPB) is off
Power mode 6 (ignition on) detected by the CJB The CJB receives an engine running signal The lighting control switch is in the off or side lamps position.
NOTES:
If the lighting control switch is moved to the headlamp position, DRL are deactivated and normal side lamp and headlamp functionality is operational.
When DRL are active, the headlamp flash function using the left hand steering column multifunction switch will operate normally.
The high beam headlamp function using the left hand steering column stalk switch will be deactivated. When the transmission
is in PARK, DRL are turned off. This is to reduce battery discharge during long periods of engine idling in cold climate conditions. When the electronic transmission selector is moved from the PARK position, normal DRL functionality is restored.
DAYTIME RUNNING LAMPS - DENMARK, HOLLAND, NORWAY, SWEDEN, FINLAND AND POLAND
NOTE: DRL for Poland is on vehicles from 2008MY.
DRL for these markets use full intensity low beam headlamps. Side lamps and license plate lamps will be on, but instrument cluster illumination will be off. DRL are active when the following parameters are met:
Power mode 6 (ignition on) detected by the CJB The CJB receives an engine running signal The lighting control switch is in the off position.
NOTE: When DRL are active, the headlamp flash function using the left hand steering column multifunction switch will operate normally. The high beam headlamp function using the left hand steering column stalk switch will be deactivated.
If the lighting control switch is moved to the side lamp or headlamp positions, DRL are deactivated and normal side lamp and headlamp functionality is operational.
AUTOMATIC HEADLAMPS
On vehicles fitted with the automatic headlamps feature, DRL are overridden if the lighting control switch is in the 'Auto' position and the CJB receives a signal from the rain/light sensor to activate the exterior lights.
When the CJB receives a signal to de-activate the automatic headlamps feature the DRL function is restored providing the parameters for DRL activation are met.

Door Modules Component Description
The door modules provide the interface between the door latch-motors, the door latch-switches and the CJB. The door modules
provide door switch status information and enable the door latch-motors on request from the CJB or the keyless vehicle
module.
Keyless Vehicle Module
The keyless vehicle module interfaces with the Central locking, Radio Frequency (RF) receiver and collects RF signal information
which is transmitted from the Smart Key. This information is translated into commands which are passed on the medium speed
CAN bus to the:
CJB,
RJB,
door modules, and
instrument cluster.
The keyless vehicle module also monitors:
2 interior antennae,
1 luggage compartment antenna,
a rear bumper antenna, and
4 door handle antennae if the passive entry system is fitted.
On vehicles with passive entry, the additional fast latch motors are controlled via the keyless vehicle module and the locking
status is passed to the CJB on the medium speed CAN bus.
Instrument Cluster
The instrument cluster controls the alarm indicator, and in conjunction with the ECM (engine control module), the engine
immobilization. The ECM controls the engine crank and fuel functions and the instrument cluster processes the valid
transponder information.
Alarm Indicator
The alarm indicator is a LED (light emitting diode) located in the body of the sunload/light sensor. When the ignition is off the
indicator gives a visual indication of the active anti-theft system to show if the alarm system is active or not active. Operation
of the alarm indicator is controlled by the instrument cluster which varies the flash rate of the LED to indicate the system
status of the alarm and the immobilization systems.
When the ignition is on, the indicator provides a visual indication of the status of the passive anti-theft (engine
immobilization) system. If the immobilization system is operating correctly, the LED will be illuminated for 3 seconds at
ignition on and then extinguish. If a fault exists in the immobilization system, the LED will be either permanently illuminated
or flashing for 60 seconds. This indicates that a fault exists and fault code has been recorded. After the 60 second period the
LED will flash at different frequencies which indicate the nature of the fault.
Refer to: Anti-Theft - Passive (419-01B Anti-Theft - Passive, Description and Operation).
Passive Anti-Theft Horn
The passive anti-theft horn is hardwired to the CJB which activates the horn when the alarm is triggered.
Battery Backed Sounder
Operation of the battery backed sounder is controlled by the CJB on the LIN bus. The sounder is also connected with a
permanent battery supply via the CJB. An integral, rechargeable battery powers the sounder if the battery power supply from
the CJB is interrupted.
Dependant on vehicle, a incitation sensor is incorporated into the battery backed sounder, to monitor vehicle attitude, see
Inclination Sensor.
Inclination Sensor
The CJB monitors the inclination sensor and will activate the alarm system if the vehicle is being raised.
Intrusion Detection Module
The intrusion detection module comprises an ultrasonic sound wave sensor which monitors the vehicle's interior.
The intrusion detection module is activated with volumetric mode which in turn is enabled when the vehicle is double locked.
The vehicle can be locked and alarmed with the module de-activated if a pet is to be left in the vehicle for example by single-
