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

Component Description
Description and Operation

Control Diagram

NOTE: A = Hardwired; N = Medium speed CAN (controller area network) bus; O = LIN (local interconnect network) bus



Item Description 1 Battery 2 EJB (engine junction box) 3 Wiper motor 4 Headlamp washer pump 5 Rain/Light sensor 6 Washer reservoir fluid level switch

7 Windshield washer pump 8 Wiper/Washer switch - RH (right-hand) steering column multifunction switch 9 Instrument cluster 10 CJB (central junction box) 11 BJB (battery junction box)


WINDSHIELD WIPERS System Operation

Operation of the wipers and washers is controlled by the CJB in response to driver inputs from the wiper control switch and signals from the rain/light sensor. The instrument cluster monitors the condition of the wiper/washer control switch and
transmits driver requests to the CJB over the medium speed CAN bus.
The wiper control switch is connected via hardwired connections to the instrument cluster. The instrument cluster outputs on 4
wires a reference voltage to the wash/wipe switch, the auto wiper switch, the wiper switch and the flick wipe switch. All the
switches are connected to the instrument cluster on a common ground. Each switch function is connected to ground via a
resistor or series of resistors and the instrument cluster monitors the ground signal and determines which function has been
selected. The instrument cluster then outputs the appropriate message on the medium speed CAN bus to the CJB which responds to the requested wiper function. The CJB then activates the appropriate function either directly or via relays in the EJB for the wipers and headlamp powerwashers. Speed Dependent Mode

When the wipers are operating, a vehicle speed signal received by the CJB on the high speed CAN bus is used to operate a speed dependent mode. If the wipers are in fast wipe and the vehicle speed decreases to below 2 km/h (1.2 mph), the wipers
will reduce to the normal wipe speed. When the vehicle speed increases to above 8 km/h (5 mph) the fast wiper speed
selection is restored. If slow speed is selected and the vehicle speed drops below 2km/h (1.2 mph), the wipers will operate in
the intermittent mode. When the vehicle speed increases to above 8 km/h (5 mph) the slow wiper speed selection is restored
– this feature is configurable by the dealer using the approved Jaguar diagnostic system.
Wiper Motor

The wiper motor is controlled by the CJB. The CJB is connected to a wiper motor normal/fast relay in the EJB on 2 wires. The CJB is also connected to a wiper run/park relay, also located in the EJB.
Driver requests are received by the CJB which energizes the wiper motor normal/fast relay in the appropriate mode (normal or fast wipe) and also energizes the run/park relay in the run mode by providing a ground for the relay coils. When wiper
operation is deselected by the driver, the CJB monitors a park switch which is integral with the wiper motor. On receipt of a signal from the park switch, the CJB de-energises the run/park relay, removing the power supply through the normal/fast relay, stopping the wipers in the park position on the windshield.

The wiper motor is a DC (direct current) motor which drives a gear wheel via a worm drive attached to the motor spindle. The
motor has 3 sets of brushes with one brush connected to ground. When the normal/fast relay is energized in the normal
position, a power feed is supplied to the brush directly opposite the ground brush and operates the motor at slow speed.
When the relay is energized in the fast position, a power feed is connected to the second motor brush, which is offset from the
ground brush and operates the motor at the fast speed. With power supplied through the offset brush, the current flows
through fewer motor coil windings. This results in a lower resistance to current flow to the ground brush and produces a higher
motor rotational speed.

WINDSHIELD WASHERS

The windshield washers are controlled by the CJB. A driver request for washer operation, via the wiper control switch, is passed to the instrument cluster on the LIN bus. The instrument cluster passes the message to the CJB on the medium speed CAN bus.

The CJB energizes the windshield washer pump during the up stroke of the first 2 wash/wipe cycles. This ensures that wiper fluid is pushed to the sides of the windshield and eliminates the trail of fluid which can occur if the fluid is pushed to the
bottom of the windshield. The wipers will continue for 3 more cycles, followed after a delay of 4 seconds, by a single dry wipe.


NOTE: The dry wipe feature is configurable using an approved Jaguar diagnostic system.

The operation of the washer pump on the wiper up stroke only is configurable using an approved Jaguar diagnostic system.

The washer button can be pressed and held and the wipers will operate continuously for up to 10 seconds. After this period
when the button is released, the wipers will continue for 3 more cycles, followed after a delay, by a single dry wipe. After this
period washing will be inhibited, the wipers will continue for 3 more cycles, followed after a delay, by a single dry wipe.
Reactivating the switch will recommence the wash/wipe cycle.

RESERVOIR LEVEL SWITCH

The level switch is connected directly to the CJB. The switch is operated by a float which closes contacts within the switch when the fluid level falls to below the switch level. When the contacts are closed a ground path is completed from the CJB through the switch. This is sensed by the CJB which issues a message to the instrument cluster which displays a low fluid level warning.

Component Description
Description and Operation

Control Diagram

NOTE: A = Hardwired



Item Description 1 Battery 2 Megafuse (250 A) 3 Rear window sunblind, switch 4 Rear window sunblind, motor 5 ABS (anti-lock brake system) module 6 Roof opening panel, control module 7 Roof opening panel, rocker switch 8 CJB (central junction box)

Roof opening panel System Operation

Operation of the roof opening panel is controlled by the roof opening panel control module, which is integral with the motor.
The control module receives inputs from the CJB, which provides an 'open' or 'close' signal for remote handset operation, and
an 'enable' signal when the vehicle enters power mode 6.

The control module also receives a vehicle speed signal from the ABS module. The vehicle speed signal is used by the control
module to calibrate the anti-trap feature.

If the battery is disconnected, or the power supply is interrupted while the roof opening panel is in a partially open position,
the motor and control module will need to be calibrated to restore full functionality. To recalibrate:
1. Switch ignition on.
2. Press the front of the switch, so the roof opening panel is the tilt position, and then release the switch.
3. Press the front of the switch and hold for thirty seconds.
4. After thirty seconds the roof opening panel will begin to move. Keep the front of the switch pressed until the roof
opening panel has fully opened and then closed.
5. Once the open/close cycle has completed and the roof opening panel has stopped moving, release the switch.
6. The roof opening panel can now be operated as normal.

Drain hoses are connected to the front and rear corners of the roof opening panel frame. The drain hoses are located inside of
the cabin on the 'A' and 'D' post pillars to allow water, which has collected in the frame, to escape. One-way valves fitted to
the end of each drain hose, prevent the ingress of dirt and moisture.

Rear window sunblind

The powered rear window sunblind is operated through a switch in the roof console. Power to the sunblind motor is provided by
a pair of relays located in the CJB when the vehicle enters power mode 4. The sunblind motor is located beneath the rear parcel
shelf and is supplied as a sealed unit with the sunblind mechanism.

If the battery is disconnected or a replacement sunblind is fitted, the motor will require re-calibrating. To re-calibrate the
motor the sunblind should be powered through two-full cycles of movement.



Roof opening panel, motor Component Description

The roof opening panel motor has a worm drive which drives a gear in the cast housing attached to the end of the motor. The
gear has a small pinion gear attached to the outer part of its spindle. The pinion engages with two cables to form a rack and
pinion drive. Rotation of the motor turns the pinion which in turn drives the cables in the required direction.

The two cables are attached either side of the pinion. One end of each cable is attached to the guide; the opposite end of
each cable is held in position on the pinion by a metal insert in the frame. The cables run in channels, in the panel frame to
the guides. As the panel is closed the cables are pushed through channels in the front of the frame. The displaced cable is
guided into a further two channels in the frame, which protect the cable and prevent it from snagging. The cables
manufactured from rigid spring steel can pull as well as push the panel along the guides.

The motor contains a micro-switch and Hall effect sensor. Signals received from these components enable the control module
to calculate the exact position of the roof opening panel. The Hall effect sensor is also responsible for the operation of the
anti-trap function.

If the anti-trap feature is activated while the roof opening panel is closing, the panel is reversed for 200mm or as far as
possible. The Hall effect sensor, located in the 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 panel goes back. In an emergency the
anti-trap function can be overridden by holding the switch in the closed position.

Roof opening panel, control module

The roof opening panel control module is integrated within the motor. The control module receives inputs from the CJB, which
provides an 'open' or 'close' signal for remote handset operation, and an 'enable' signal when the vehicle enters power mode 6.

The control module also contains the algorithm for the anti-trap system and receives a vehicle speed signal from the ABS
module. The vehicle speed signal is used by the control module to calibrate the anti-trap feature.
