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.

workshop manual. REFER to: (417-02 Interior Lighting)
Interior Lighting (Description and Operation), Interior Lighting (Description and Operation), Interior Lighting (Description and Operation).
Inspection and Verification
CAUTION: Diagnosis by substitution from a donor vehicle is NOT acceptable. Substitution of control modules does not
guarantee confirmation of a fault, and may also cause additional faults in the vehicle being tested and/or the donor vehicle.
1. Verify the customer concern.
2. Visually inspect for obvious signs of damage and system integrity.
Visual Inspection
Mechanical Electrical
Bulbs
Fuses/relays (refer to electrical guide)
Wiring harness
Correct engagement of electrical connectors
Loose or corroded connections
3. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to
the next step.
4. If the cause is not visually evident, check for Diagnostic Trouble Codes (DTCs) and refer to the DTC Index.
DTC Index
CAUTION: When probing connectors to take measurements in the course of the pinpoint tests, use the adaptor kit, part
number 3548-1358-00
NOTES:
If the control module or a component is suspect and the vehicle remains under manufacturer warranty, refer to the
Warranty Policy and Procedures manual (section B1.2), or determine if any prior approval programme is in operation, prior to
the installation of a new module/component.
Generic scan tools may not read the codes listed, or may read only five digit codes. Match the five digits from the scan
tool to the first five digits of the seven digit code listed to identify the fault (the last two digits give extra information read by
the manufacturer-approved diagnostic system).
When performing voltage or resistance tests, always use a digital multimeter (DMM) accurate to three decimal places and
with a current calibration certificate. When testing resistance, always take the resistance of the DMM leads into account.
Check and rectify basic faults before beginning diagnostic routines involving pinpoint tests.
If DTCs are recorded and, after performing the pinpoint tests, a fault is not present, an intermittent concern may be the
cause. Always check for loose connections and corroded terminals.

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.

MOST prism. The MOST prism is connected in the same way as the MOST tester but will simply reflect any existing signal
onward to the next control module. Using the MOST prism before or after a long run of harness may cause a ring break as a
good signal may be too weak after travelling the extended distance. Also, the MOST prism will pass light in either direction so
will not detect reversed MOST terminals elsewhere in the network. For these reasons, the MOST tester is the preferred tool and
should be used unless limited access does not permit it
MOST Ring Break Indication
A ring break in the MOST network is indicated by a blank touch screen display if the break is before the touch screen display or
a flashing logo of the break is after the touch screen display. Possible causes of ring breaks are listed in the symptom chart
