2010 JAGUAR XFR door lock

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.

Anti-Theft - Active - Anti-Theft - Active - Overview
Description and Operation

Overview Published: 11-May-2011

The active anti-theft system is available with three different levels of vehicle protection depending on market specification:

Hinged panel sensing
Hinged panel and intrusion sensing
Hinged panel, intrusion and inclination sensing.

The CJB (central junction box) automatically arms and disarms the active anti-theft system when it functions the central
locking system.
Refer to: Handles, Locks, Latches and Entry Systems (501-14 Handles, Locks, Latches and Entry Systems, Description and Operation).
Depending on market specification two modes of protection are used: perimeter mode and volumetric mode.

Perimeter mode
Perimeter mode, monitors the security of the hinged panels, which include:
all doors,
luggage compartment lid, and
engine compartment lid.

When perimeter mode is active, the CJB monitors the panel ajar switches in the latch mechanisms of the hinged panels.
Volumetric mode

In volumetric mode the CJB monitors the interior of the vehicle for movement using an ultrasonic sound wave sensor.

If the battery backed sounder incorporates an inclination sensor the vehicle will also be monitored for unauthorised tilting; for
example towing or jacking.

Anti-Theft - Active System Operation

The active anti-theft system is available with three different levels of vehicle protection depending on market specification:
Hinged panel sensing
Hinged panel and intrusion sensing
Hinged panel, intrusion and inclination sensing.
The system is controlled by software in the CJB and RJB and indicates a trigger condition: Visually, using the direction indicators, and
Audibly, using the vehicle horn and either a passive or active sounder to indicate a trigger condition.

The passive sounder takes the form of an anti-theft disc horn located at the rear of the engine compartment on the LH side. The active sounder takes the form of a battery backed sounder located in the same position.

Depending on market specification, the battery backed sounder may be fitted with an inclination sensor. Both types of battery
backed sounder are visually identical and can only be identified by their part number. Both are also intelligent units, and
communicate to the CJB over a LIN (local interconnect network) bus connection.

Monitoring of the hinged panels is carried out using switches located in each door latch assembly, the engine-compartment-lid
latch assembly, and the luggage-compartment-lid latch assembly. The condition of the switches is monitored by the CJB.

Monitoring of front door lock status is carried out using switches located in the door latch mechanisms. The condition of the
switches is monitored by the front door modules and transmitted to the CJB over the medium speed CAN (controller area
network) bus.

Monitoring of the cabin interior is carried out using an intrusion detection module mounted behind the roof console. The
intrusion detection module comprises an ultrasonic sound wave sensor to determine if there is movement within the cabin.
Information from the intrusion detection module is communicated to the CJB over a LIN bus connection.
CAUTIONS:

The intrusion detection module electrical connections, particularly those to the sensors mounted in the roof console, are
very delicate and must be handled with care.


The intrusion detection module is an electro-statically sensitive part and should only be handled in an electro-statically
controlled environment.
When armed, the active anti-theft system can be triggered in one of the following ways:
A door ajar switch indicates a door has been opened.
The engine compartment lid or luggage compartment lid ajar switches indicate that either has been opened.
Either front door latch mechanism indicates a door has been unlocked.
The emergency key blade is used to open either the LH front door or luggage compartment.
The CJB or RJB are disconnected (this may result in only a partial trigger).
An attempt is made to start the engine without a valid signal from the Smart Key.
Refer to: Anti-Theft - Passive (419-01B Anti-Theft - Passive, Description and Operation).
