Door lock JAGUAR XFR 2010 1.G Repair Manual

8 LH door module 9 Exterior mirror control switches
System Operation
The rear view mirrors comprise an interior mirror mounted to the windshield, and an exterior mirror mounted on each front door
cheater. The types of mirrors and associated operating functions installed depend on the specification and trim level of the
vehicle.

Interior Mirrors

The interior rear view mirror is provided as a manual dimming or an electrically operated automatic dimming type.

The manual dimming mirror comprises a prismatic glass housed within a surrounding case that is attached with a ball joint
connector to the mirror stem. Manual dimming of the mirror is achieved using the lever mounted on the underside of the mirror
body. Operating the lever will tilt the mirror head from the 'day' position to the 'night' position.

The automatic dimming mirror comprises an electro-chromatic glass housed within a surrounding case that is attached with a
ball joint connector to the mirror stem. The mirror stem incorporates an 8-pin electrical connector that is connected to the roof
panel wiring harness. The wiring harness provides hardwired and a LIN connection to the CJB.
Light sensors are mounted on the front and rear of the mirror surround case. The sensors control the automatic dimming
feature to reduce glare from the headlights of following vehicles.

The automatic dimming function is permanently active when the ignition is in power mode 4 (Accessory) and power mode 6
(Ignition). The forward facing light sensor monitors the ambient light level at the front of the vehicle; the rearward facing light
sensor monitors the light level coming from the rear of the vehicle. When light from the rear of the vehicle exceeds the
ambient light level from the front of the vehicle, the automatic dimming circuit darkens the interior mirror surface.

Automatic dimming is inhibited when reverse gear is selected to provide the driver with maximum vision. On vehicles with
automatic transmission, the reverse gear signal is provided by the TCM (transmission control module) via the high speed CAN bus to the CJB. The CJB then provides a power feed to the mirror. On vehicles with manual transmission, the reverse gear signal is provided by a transmission switch that is hardwired to the CJB.
Exterior Mirrors

Electrically operated and heated exterior mirrors are installed as standard. Depending on the specification and trim level of the
vehicle, the following options are available:

Power fold (switch pack operated feature) and auto fold (remote handset operated feature)
Memory recall
Reverse gear mirror dip
Mirror heating
Exterior mirror lamps.

The power fold/auto fold feature is available only when power fold mirrors are installed to the vehicle.

The mirrors can be configured to automatically fold when the vehicle is locked and unfold when unlocked. This feature can be
enabled or disabled via the Vehicle settings area of the touch screen:

Select 'Settings' from the touch screen Home menu.
Select ' Security/Vehicle'
Select 'Windows/Mirrors'
Select Power Fold 'On' or 'Off' as appropriate.

The pasenger side mirror can be configured to automatically dip when reverse gear is selected. This feature can be enabled or
disabled via the Vehicle settings area of the touch screen:

Select 'Settings' from the touch screen Home menu.
Select ' Security/Vehicle'
Select 'Windows/Mirrors'
Select Reverse dip 'On' or 'Off' as appropriate.

The LH door mirror incorporates an ambient air temperature sensor that is hardwired to the ECM (engine control module). The ECM is connected to the CJB and other control modules via the high speed CAN bus. The sensor provides information to the ECM that is then transmitted on the medium speed CAN bus for use by other control modules. On vehicles installed with a high-line instrument cluster, the CJB transmits the temperature signal to the instrument cluster that provides a display of the ambient temperature to the driver.
The exterior mirror lamps are controlled by the interior lighting function.

The door mirrors are controlled using a switch pack located on the driver's door. The switch pack contains 2 non-latching mirror
select switches labeled 'L' and 'R' and a 4-way directional joystick. The switch pack is connected to the driver door control
module via the LIN bus. The driver and front passenger door control modules are connected via the medium speed CAN bus. A hardwired connection between each door control module and the corresponding door mirror, provides the supply and ground
paths for the mirror motors.
Each exterior door mirror incorporates 2 motors to control horizontal (left/right) and vertical (up/down) adjustments. www.JagDocs.com

On vehicles installed with a driver's power operated memory seat and memory exterior mirrors, a potentiometer is incorporated
within each mirror motor and is used to provide information regarding the actual motor positions. The current position and
memory positions of each door mirror motor are maintained and stored within the corresponding door control module.

The memory exterior mirror positions are also monitored and stored within door control module memory when the reverse gear
mirror dip function is used.

When reverse gear is selected, the door control module stores the current mirror positions and will then dip the passenger
mirror glass to a default dip position. While reverse gear is selected it is possible to store a preferred dipped mirror position by
adjusting the driver/passenger mirror glass to the desired position via the mirror switch pack. When the desired position is
achieved using the switch, the new dip positions will be automatically stored by the door control module when reverse gear is
de-selected. Therefore when reverse gear is re-selected, the dip position recalled by the door control module will be the new
reverse gear mirror dip stored position. When reverse gear is deselected the mirror glass will automatically move to the previous
stored position prior to reverse gear selection.

If the driver selects a memory recall function using the memory seat switch pack, the driver's memory seat and exterior
memory mirrors are moved to a stored memory position.

Exterior mirrors with the power fold/auto fold feature incorporate a motor located in the hinge of each exterior mirror arm.
Operation of the power fold feature is achieved using the exterior mirror switch pack. Operation of the auto fold feature is
achieved using the remote handset.
The power fold function is active when the ignition is in power mode 6 (Ignition).

Both exterior mirrors will power fold when the mirror switch pack 'L' and 'R' switches are pressed together. Pressing the
switches again will unfold the mirrors.

When the instrument cluster is configured for the auto fold feature, the mirrors will fold in when the remote handset lock
button is pressed. The mirrors will unfold when the vehicle is unlocked using the remote handset unlock button.


NOTE: If the mirrors are folded in using the mirror switch pack (power fold) and the vehicle is then locked, subsequent
unlocking of the vehicle will not unfold the mirrors.

When the remote handset unlock button is operated, the CJB recognizes the remote handset for that vehicle and acknowledges the request. The door control modules are connected directly to the AJB (auxiliary junction box) for power supply to the
exterior mirror folding motors.

When the vehicle is locked the door control modules reverse the polarity of the mirror fold motor, power and ground
connections to operate the mirrors in the opposite direction.

Exterior mirror heating is provided with heater elements bonded to the back of the mirror glass. Power supply for the mirror
heating elements is provided by the corresponding driver or passenger door control module via the RJB. The door control modules receive a power supply from the RJB, and are both connected on the medium speed CAN bus to the ATC (automatic temperature control) module. A ground terminal from each door control module completes the circuit. The ATC module automatically controls the mirror heating function whenever the ignition is in power mode 4 (Accessory) and power mode 6
(Ignition).

Operation of the exterior mirror heaters is fully automatic and not controllable by the driver. Exterior mirror heater operation is
determined by ambient air temperature and windshield wiper status. When ambient air temperature reaches a pre-determined
level, the ATC module broadcasts an exterior mirror heating request to the door modules over the medium speed CAN bus. On receipt of this message, the door modules provide feed and ground connections to both exterior mirror heater elements.

The mirror heating is controlled in two phases, the initial heating phase and a second PWM (pulse width modulation) controlled
phase. In the first phase the heater elements in the mirrors are permanently powered for a pre-determined length of time. This
length of time varies with the ambient temperature. During the second PWM phase, the heater elements are turned on and off every 30 seconds. The amount of time the exterior mirror heaters are operational increases if the windshield wipers are
switched on. This ensures the mirrors remain mist free in damp and wet conditions, where there is an increased risk of misting.

Door Windows System Operation

All windows can be operated individually, or by the driver’s window control switch. The operation of the windows is proportional
to the switch activation. All windows can be controlled by ‘one touch’ in an upward or downward direction. When the ‘one
touch’ operation is activated in the upwards direction ‘pinch protection‘ is enabled. If a pinch condition is detected the window
will automatically stop and travel downwards to a pre-determined position.

When the rear window ‘one touch’ operation is activated in the downward direction, the window will drop a limited way down.
This is the comfort setting to achieve optimum noise levels when vehicle is in motion with rear windows open. Further ‘one
touch’ operation will drop the window all the way down. (Only applies to vehicles post VIN R99740) The ‘one touch’ operation
to activate the upward direction will fully close the window.

Electric window operation is enabled while the ignition is in power mode 4 and 6. When the switches in the driver's door are
used to operate the passenger windows, the driver's door module outputs a related message on the LIN (local interconnect
network) bus and medium speed CAN (controller area network) bus. The passenger door module responds to the message by
operating the appropriate window. When the child lock is engaged, the rear door modules ignore inputs from the rear window
switches.
End of travel shut off

End of travel shut-off for the window motors is determined by monitoring the current draw of the motors. Each time it switches
on a window motor, the door module measures the window motor current for a preset time. The maximum value measured
within that time is stored as the switch-on current. When the window motor current next exceeds the switch-on current, the
door module assumes the window has reached the end of its travel and switches off the power supply to the window motor
even if a window switch is still being activated.
Anti-trap

The anti-trap function is enabled for window closing in both the inching and one-shot modes. If the anti-trap feature is
activated while a window is closing, the window motor is reversed for a preset period.

A Hall sensor, located in the window regulator motor, monitors the speed of the motor and if the speed decreases below a set
threshold, indicating an obstruction, the power feed to the motor is reversed so the window goes back down for preset time.
In an emergency the anti-trap function can be overridden by holding the window switch in the one-shot closed position.

After the battery has been disconnected it is necessary to initialize the door window motors to be able to operate the one-shot
up function.


Windshield Component Description

The windshield, manufactured from 5mm laminated green-tinted glass is positioned to the vehicle's body by two locator pins,
one in each top corner of the windshield. This allows for centralizing movement of the windshield across the car upon fitment.
The base of the windshield carries a leaf-screen retainer. The windshield is bonded and sealed to the vehicle body aperture
using Polyurethane (PU) adhesive. The windshield finisher is a three-sided extruded flip, taped onto the inner surface of the
glass; this helps to centralize the glass in the aperture.
Two variants of windshield are available:
standard, and
heated.
Refer to: Control Components (412-01 Climate Control, Description and Operation).

System Operation

The hinged panels are secured with latches and strikers. A remotely operated central locking system controls the locking and
unlocking of the door and luggage compartment latches. A radio frequency Smart Key allows the vehicle to be locked and
unlocked by pressing the appropriate handset buttons. Two levels of central locking system are available: remote central
locking and an optional passive entry system.

The passive entry and associated passive start system allows the driver to unlock and start the vehicle without using a vehicle
key in a door-lock or ignition switch. The passive entry system is an optional fitment while the passive start system is a
standard fitment on all vehicles. The passive start system is combined with the passive anti-theft immobilization system.
Refer to: Anti-Theft - Passive (419-01B Anti-Theft - Passive, Description and Operation).
Emergency access to the vehicle is provided by two concealed key barrels: one located in the front left-hand door handle and
one located on the underside of the luggage compartment lid finisher. An emergency, removable key blade is fitted into the
Smart Key.

Operation of either key barrel unlocks the vehicle but does not disarm the alarm system. The key barrels in the door and
luggage compartment lid are concealed by a plastic cover which can be removed by inserting the blade of the emergency key
into a slot in the cover.
Locking and unlocking conditions using the emergency key in the door key barrel:
If the alarm is not armed the vehicle can be centrally unlocked.
If the alarm is armed the door only can be opened and the alarm will be triggered.
The vehicle cannot be double locked or the alarm system armed using the emergency key.

The vehicle can be centrally locked and unlocked from inside using the interior handle release levers on the front doors only.
Central locking and unlocking can also be performed using lock and unlock buttons on the vehicle's fascia. The driver can select
locking options, single point entry or drive away locking for example, from a menu available on the touch screen.

Central Locking – Radio Frequency Remote System

The radio frequency central locking system, provides locking and unlocking of the vehicle from inside and outside of the
vehicle. The system is operated using buttons on the Smart Key, which transmits radio frequency signals to the central locking
radio frequency receiver.

The system provides additional security by double-locking the doors from outside the vehicle if the lock button, on the Smart
Key, is pressed twice within 3 seconds; this function is not applicable in North American Specification (NAS) and Japanese
markets.

Additional buttons on the Smart Key provide for the convenience operation of the luggage compartment lid release, headlamp
delay and panic alarm functions. A global open or close feature is also available in certain markets using the lock/unlock
buttons.

Passive Entry

On vehicles fitted with the optional passive entry system, the vehicle can be unlocked without the use of a key blade or
pressing buttons on the Smart Key. The Smart Key operates the passive entry system in addition to the passive start system.
Refer to: Anti-Theft - Passive (419-01B Anti-Theft - Passive, Description and Operation).
The passive entry system is controlled by the keyless vehicle module and five low frequency antennas. One antenna located in
each door handle and one antenna located behind the rear bumper cover.

When a vehicle door handle is pulled to the first five-percent of its travel and the Smart Key is within one meter of the handle;
the Smart Key receives the low-frequency signal transmitted from the keyless vehicle module. The Smart Key responds with a
radio frequency transmission of its authorization code. The radio frequency signal is received by the central locking radio-
frequency receiver and passed to the keyless vehicle module which checks and approves the code as valid. Once the handle is

door modules.

Locking of the vehicle is performed by pressing one of the buttons located on each exterior door handle, with the Smart Key
within a one meter range of the vehicle. When the door handle button is pressed, the keyless vehicle module transmits a
low-frequency signal via the low-frequency handle antenna to the Smart Key. The Smart Key transmits a radio frequency signal
which is verified by the keyless vehicle module and allows the doors to be locked or double locked and the alarm system to be
armed.

To double lock the vehicle, the button on the exterior door handle must be pressed twice within three seconds, with the Smart
Key within one meter range of the vehicle.

If a door, engine-compartment lid or the luggage compartment lid is ajar when an attempt to lock the vehicle is made, an error
tone is emitted and no locking action will occur.
Refer to: Anti-Theft - Active (419-01A Anti-Theft - Active, Description and Operation).


Engine Compartment Lid Latches Component Description

Two engine-compartment lid latches are located on the front crossmember. An engine-compartment lid release lever is located
below the instrument panel on the left-hand 'A' pillar and is connected with a cable to the latches. An engine-compartment lid
ajar switch is integrated in the engine-compartment lid latch.

Door Latches

The door latches are located at the rear of each door and engage with a striker on the adjacent pillar. Each door latch motor
assembly contains micro-switches for lock, unlock and door ajar. Motors provide for the central door locking and the double
locking feature. The electrical control for the door latch components is provided by the CJB and RJB via the driver's and
passenger door modules.

The interior door handles are connected by a cable to the latch release mechanisms. The interior door handles also incorporate
a locking facility to allow the doors to be locked from inside the vehicle when all the doors are closed. If a door is ajar the
locking feature is inhibited.

Luggage Compartment Lid Latch

The luggage compartment latch is attached to the bottom of the lid. The latch can be released electrically by pressing the
interior release button located on the outboard side of driver's lower knee bolster; a release button is also provided on the
Smart Key. There is also a release switch on the underside of the luggage compartment lid finisher.

On NAS vehicles an emergency release cable is attached to the latch. This allows the latch to be manually opened by pulling a
handle located in the luggage compartment lid interior trim.

Fuel Filler Door

The fuel filler door is electrically locked by a motor located on the fuel door housing. The fuel door is locked when the vehicle
is locked and alarmed. The fuel door can be opened when the vehicle is unlocked or locked:

via an interior handle,
via drive-a-way locking,
via the lock switch on the fascia,
via the external door key barrel. www.JagDocs.com
