dependant on a particular ignition mode status. The side lamps will also be illuminated when the lighting control switch is in
the AUTO position and a 'lights on' signal is received by the CJB from the rain/light sensor Side Marker Lamps (NAS only)

The side marker lamp is located in the outer part of the headlamp assembly. The side marker lamp uses a W5W wedge fitting
bulb. The bulb is fitted into a holder which connects with contacts in the headlamp housing. The holder is fitted into an
aperture which connects with contacts in the headlamp housing. The side marker lamp is active at all times when the side
lamps are active.

AUTOMATIC HEADLAMP OPERATION

The automatic headlamp function is a driver assistance system. The driver can override the system operation by selection of
side lamp or headlamp on if the ambient light conditions require front and rear lighting to be active. The automatic headlamp
system uses a light sensor and the CJB, which are connected via a LIN (local interconnect network) bus to control the headlamp functionality. The light sensor is incorporated in the rain/light sensor located on the inside of the windshield, below
the rear view mirror. The wiper system also uses the rain/light sensor for automatic wiper operation.

The light sensor measures the ambient light around the vehicle in a vertical direction and also the angular light level from the
front of the vehicle. The rain/light sensor uses vehicle speed signals, wiper switch position and the park position of the front
wipers to control the system. The automatic headlamp operation uses ambient light levels which are monitored by photodiode
incorporated in the rain/light sensor. The rain/light sensor sends a lights on/off request to the CJB on the LIN bus, which responds by switching on the low beam headlamps, front side lamps and rear tail lamps. The automatic headlamps are
activated under the following conditions:

Twilight
Darkness
Rain
Snow
Tunnels
Underground or multistoried car parks.

Operation of the automatic headlamps requires the ignition to be in ignition mode 6, the lighting control switch to be in the
'AUTO' position and a lights on request signal from the light sensor. If the rain sensor signal activates the fast speed wipers,
the low beam headlamps are activated, providing the lighting control switch is in the 'AUTO' position.

HEADLAMP LEVELING

Headlamp leveling provides for the adjustment of the vertical aim of the headlamps. The leveling system is primarily required
to minimise glare to other road users when a heavy load is in the rear of the vehicle. Two systems of headlamp leveling are
available; manual and static dynamic.
Manual Headlamp Leveling

The manual system uses a thumbwheel rheostat to adjust the vertical alignment of the headlamps to compensate for differing
vehicle loading. The rotary thumbwheel is located on the auxiliary lighting switch, adjacent to the illumination dimmer
thumbwheel. Three positions are available to adjust the headlamps to a position to prevent glare to other road users.
Static Dynamic Headlamp Leveling
The static dynamic headlamp leveling system uses the following components:
Front and rear vehicle height sensors
Two headlamp leveling, vertical adjustment motors
Headlamp leveling module
Ignition in mode 6
Vehicle speed information from ABS module.
The static dynamic system uses height sensors fitted to the front and rear suspension and a headlamp leveling module which
periodically monitors the vehicle attitude and adjusts the headlamp vertical alignment accordingly.

Static dynamic headlamp leveling is controlled by a headlamp leveling module located in the lower instrument panel, behind
the glovebox.

The height sensors are both located on the RH side of the vehicle. The front sensor is attached to the front suspension lower arm with a strap and to the front sub frame with a bracket and 2 bolts. The rear sensor is attached to the rear suspension
upper control arm with a cable tied clip and to the rear sub frame with a bracket and 2 bolts. Each sensor has 3 connections to
the headlamp leveling module; power, ground and signal.

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.

7 Low frequency antenna - front 8 Low frequency antenna - center 9 Low frequency antenna - rear 10 Radio frequency receiver 11 Start control module 12 CJB (central junction box) 13 Instrument cluster 14 Megafuse (250 amp)
System Operation

The passive start function prevents the vehicle from being started by unauthorized persons. It does this by immobilizing the
ignition, fuel and engine crank functions. The system is automatic and requires no input from the driver.

At the request of the CJB, the keyless vehicle module prompts each of the Low Frequency (LF) antennae to output a signal. When the Smart Key is in the vehicle cabin, it detects the LF signals and responds with a Radio Frequency (RF)
data-identification signal back to the keyless vehicle module via the RF receiver.

If the data received matches that stored in the keyless vehicle module it continues the passive start process by
communicating a 'Smart Key valid’ signal to the CJB via the medium speed CAN (controller area network) bus.

Once the CJB receives the authorization and confirms a response with an internal calculation, it passes the result to the
instrument cluster on the medium speed CAN bus.
Before the instrument cluster sends a mobilization signal to the ECMit will exchange encrypted data with: The electric steering lock mechanism to authorize unlocking the steering column.
The RJB to authorize fuel pump operation. Once the RJB receives the authorization and confirms the response with an internal calculation, it will enable the FPDM (fuel pump driver module).
The CJB to authorize the ignition status. If the drive selector is in the park position and the driver presses the brake
pedal and simultaneously presses the start/stop switch, the CJB interprets this as an engine crank request. Before the
engine crank request is allowed, the CJB compares a brake pressure signal received from the ABS module. The brake pressure signal is compared to an internally stored threshold value within the CJB. If the signal is greater than the
stored threshold value, a crank request signal is sent to the ECM on the high speed CAN bus.

Once these factors have been confirmed, and the vehicle is in 'Park', the engine can be started by pressing the brake pedal and
the Stop/Start button simultaneously.
NOTES:


If the keyless vehicle module fails to locate the Smart Key, the message 'SMART KEY NOT FOUND PLEASE INSERT IN
SLOT' will appear in the instrument cluster message center. When inserted the start control module will read the transponder
within the Smart Key. If the transponder identification is valid, authorization will be transmitted to the instrument cluster on
the LIN (local interconnect network) bus.


When the vehicle is delivered from the factory the passive start function is inhibited. In this condition the vehicle can
only be started by placing the Smart Key in the start control module. The system should be switched on during the Pre-Delivery
Inspection (PDI) using the Jaguar approved diagnostic system. For additional information, refer to the PDI Manual.

To ensure optimum long term reliability of the smart key the battery must be replaced with a brand new, unused battery. If a
used battery is installed the "SMART KEY BATTERY LOW" message may not be cleared. To avoid contamination of the contacts
the battery should be removed from its packaging and installed into the smart key while wearing gloves. To confirm that the
replacement battery is working correctly press the unlock button twice while holding the smart key outside the vehicle, then
enter the vehicle with the smart key, press the start button and confirm that the "SMART KEY BATTERY LOW" message is not
displayed.



Start Control Module Component Description

The start control module is used if the keyless vehicle module is unable to authorise the Smart Key.

If the keyless vehicle module is unable to identify the Smart Key, for example if the Smart Key battery voltage is low or there
is local RF interference, the transponder within the Smart Key can be read in the conventional manner. The driver will be
alerted to this by a chime and a message in the instrument cluster message center 'SMART KEY NOT FOUND PLEASE INSERT IN
SLOT'.

Once inserted the start control module will read the transponder within the Smart Key. If the transponder identification is
valid, authorization will be transmitted to the instrument cluster on the LIN bus.


NOTE: Inserting the Smart Key into the start control module will not charge the Smart Key battery. The battery is
non-chargeable and must be replaced if defective.
