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

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.

The console can be removed by carefully levering out
the rear edge of the housing to release 2 spring clips, and then pulling the console rearwards to release 2 locating tabs.
Removal of the console is required to replace any of the interior or map reading lamp bulbs.

The interior lamps and air bag off warning lamp in the front overhead console are common to all vehicles. The overhead
console can also contain security system intrusion detection module and volumetric sensors, sunroof switch and a voice
activation microphone depending on vehicle specification and market.

The interior lamp can operated manually using the JaguarSense feature to switch the lamp on and off. The lamp is also
controlled as part of the automatic interior lighting system.
The map reading lamps only operate manually using the JaguarSense feature to activate the lamps.

The interior and map reading lamp bulbs are located in holders which locate in a PCB. The PCB also provides for the operation
of the ambience lighting LED's, the air bag off warning lamp and the JaguarSense proximity sensors which are integral with the PCB.

The overhead console also contains 2 LED's for the ambience lighting system. The ambience lighting is part of the lighting control switch functionality and is subject to the setting of the instrument panel illumination dimmer control in the auxiliary
lighting switch. The ambience lighting provides very limited illumination of the instrument panel and floor console when the
vehicle is being driven without affecting the driver's visibility. www.JagDocs.com
