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.

and the safety belt buckle sensor. Based on this data, the RCM decides which level of airbag module deployment is required and forwards the information to the second area, the deployment handler.
The deployment handler evaluates the status of the seat track position sensor and safety belt buckle sensors before a decision
is made about which restraints should finally be deployed.
Data from the side crash sensors is used by the RCM in conjunction with acceleration data from the RCM internal accelerometer to make a deployment decision. The RCM processes the acceleration data and subject to an impact being of high enough severity, decides whether the side airbag module should be deployed.
On board testing of the airbag modules, front safety belt pretensioner firing circuits, warning indicator circuits and module
status (the crash and side impact sensors perform basic self-tests) is performed by the RCM together with the storing of fault codes.
The RCM drives the SRS indicator on the instrument pack via a CAN signal. If the warning lamp fails, a fault code is recorded and a warning tone is sounded in place of the lamp if a further fault occurs. It also provides a temporary back-up power supply
to operate the airbag modules in the event that in crash conditions, the battery supply is lost. In the event of a crash, it
records certain data which can be accessed via the diagnostic connector.
A safing sensor in the RCM provides confirmation of an impact to verify if airbag and pretensioner activation is necessary. A roll-over sensor monitors the lateral attitude of the vehicle. Various firing strategies are employed by the RCM to ensure that during an accident only the appropriate airbags and pretensioners are fired. The firing strategy used also depends on the
inputs from the safety belt switches and the occupant monitoring system.
An energy reserve in the RCM ensures there is always a minimum of 150 milliseconds of stored energy available if the power supply from the ignition switch is disrupted during a crash. The stored energy is sufficient to produce firing signals for the
driver airbag, the passenger airbag and the safety belt pretensioners.
When the ignition is switched on, the RCM performs a self-test and then performs cyclical monitoring of the system. If a fault is detected the RCM stores a related fault code and illuminates the airbag warning indicator. The faults can be retrieved by the recommended Jaguar diagnostic tool over the CAN bus. If a fault that could cause a false fire signal is detected, the RCM disables the respective firing circuit, and keeps it disabled during a crash event.
Clock Spring
The clockspring is installed on the steering column to provide the electrical interface between the fixed wiring harness of the
steering column and the components that rotate with the steering wheel, i.e. the driver airbag, the horn and the steering
wheel switch packs.
The clockspring consists of a plastic cassette which incorporates an outer cover fixed to the steering column and an inner rotor
which turns with the steering wheel. Four securing lugs attach the cover to the multifunction switch on the steering column.
The rotor is keyed to the steering wheel by a drive peg. A lug on the underside of the rotor operates the self-cancelling feature
of the turn signal indicator switch. A ribbon lead, threaded on rollers in the rotor, links two connectors on the cover to two
connectors on the rotor. Link leads for the driver airbag are installed in one of the connectors on the rotor.
To prevent damage to the ribbon lead, both the steering and the clockspring must be centralized when removing and installing
the clockspring or the steering wheel. The clockspring is centralized when the drive peg is at six o'clock and 50 - 100% of a
yellow wheel is visible in the viewing window.
Replacement clocksprings are fitted with a stopper, which locks the cover to the rotor, in the central position. The stopper must
be broken off when the replacement clockspring is installed.
