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.

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.

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.

CAN Harness Architecture

For a detailed description of the CAN Networks and architecture, refer to the relevant Description and Operation section in the
Workshop Manual.
CAN Network Integrity Tests

If a control module is suspected of non-communication, the Network Integrity test application available on the manufacturer
approved diagnostic system can be used to confirm if communication is possible between the control modules on the vehicle
and the manufacturer approved diagnostic system (via the J1962 diagnostic connector ). The results from the test can be used
to determine if either a single module or multiple modules are failing to communicate.
CAN Terminating Modules

If the Network Integrity test indicates that one or more module on one of the CAN networks (HS or MS) are failing to
communicate, there are several checks that can be made. The first step is to identify if both of the CAN terminating modules
on each individual CAN Bus are communicating. If both CAN terminating modules for each individual CAN Bus are
communicating (identified via the Network Integrity test), then it can be confirmed that the main 'backbone' of the CAN
harness is complete. The main 'backbone' of the CAN harness consists of all the modules connected to the CAN harness via a
'loop' configuration and also includes the two terminating modules.

Communication with both CAN terminating modules via the Network Integrity test confirms the physical integrity of the main
'backbone' of the CAN harness (and the harness spur to the J1962 diagnostic connector). This means that there is no
requirement to check the resistance of the CAN Network. This is because the standard check for 60 ohms across the CAN High
and CAN Low lines will not provide any additional information regarding the physical condition of the CAN harness, beyond
what has already been determined from the Network Integrity test.
Non-Communication of a Terminating Module

If a Network Integrity test reveals a terminating module is failing to communicate it can indicate a break in the main
'backbone' of the CAN harness. The first checks should always be to confirm the power and ground supplies to the
non-communicating module are correct. Providing these are correct, the resistance between the CAN High and CAN Low lines at
the J1962 connector can be checked to determine the integrity of the main 'backbone' of the CAN harness. After disconnecting
the battery a reading of 120 ohms would indicate an open circuit in the main 'backbone' of the CAN harness. Alternatively, a
reading of 60 ohms would indicate that there is no open circuit fault with the main 'backbone' of the CAN harness.

It is worth noting that even if one of the terminating modules is disconnected from the CAN harness, communications between
the modules still connected may still be possible. Therefore communication between the manufacturer approved diagnostic
system and the connected modules may also be possible.
Locating CAN Harness Open Circuits

In the case where multiple modules, including a terminating module, are failing to communicate, having first confirmed the
power and ground supplies are correct, the approximate location of the open circuit can be identified from analysis of the
Network Integrity test results and reference to the relevant CAN network circuit diagrams. For example, if an open circuit
existed in a certain position on the CAN harness, any module positioned on the Network between the J1962 connector and the
open circuit should return a response during the Network Integrity test. No responses would be returned from any modules
past the open circuit fault in the Network.
CAN Harness 'Spur' Type Configuration Circuits

If, after the initial checks (Network Integrity test using the manufacturer approved diagnostic system, and power and ground
supplies to the module have been checked and confirmed as correct), a module that is connected to the CAN harness via a
'spur' type configuration is suspected of not communicating, then the physical integrity of the CAN harness 'spur' can be
checked.

This is most easily undertaken by individually checking the continuity of the CAN High and CAN Low lines between the
non-communicating module connector (with the module disconnected) and the J1962 diagnostic connector.
'Lost Communications' DTCs

As well as the methods described so far in this document, which can be used to determine the location of an open circuit in
the CAN harness, 'Lost Communications' DTCs can also be used for this purpose. Lost communication DTCs mean that a
module is not receiving CAN information from another module.

For example, if a global DTC read were to be carried out, only DTCs stored in the modules that the manufacturer approved
diagnostic system could communicate with would be displayed. If there was an open circuit fault in a certain position on the
CAN harness, the modules that could display DTCs would all be prior to the open circuit on the Network, and these modules
should display 'Lost Communications' DTCs with all the modules located on the Network past the open circuit fault.
'Bus off' DTCs
The references to bus and its condition refer to the network concerned and the modules on that network.

If a module logs a 'Bus Off' DTC, it means that the module has detected CAN transmission errors and has disabled it's own
CAN transmissions and disconnected itself from the network in an attempt to allow the rest of the network to function. At this
point the 'Bus Off' DTC is set. A common cause of 'Bus Off' DTCs can be a short circuit in the CAN network.

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
