PARKING AID System Operation

Two levels of parking aid system can be fitted; a rear only system or a front and rear system.
The parking aid module receives and ignition power mode 6 supply from the RJB. The parking aid module is connected to the entertainment system control module by the medium speed CAN (controller area
network) bus and the Media Orientated System Transport (MOST). The entertainment system is used by the parking aid system
to provide the driver with an audible warning. If an obstacle is sensed by the rear parking aid sensors, the rear audio system
speakers will sound. If an obstacle is sensed by the front parking aid sensors (if fitted), the front audio system speakers will
sound.

The parking aid system operates using ultrasonic signals which are transmitted by the sensors. The reflected echo from this
output is received by the sensors and used by the parking aid module to calculate the distance from an object.

When the parking aid module activates the system, the switch LED (light emitting diode) is illuminated to indicate that the
system is operating. The parking aid module then processes signals received from the sensors to determine if there is an
object with the detection range of the sensors. A parking aid screen is automatically displayed in the Touch Screen Display. If
the vehicle has a parking aid camera fitted, the camera display is automatically displayed in the TSD in preference to the
parking aid alert display. To view the parking aid sensor display, a single touch of the TSD screen will remove the camera
image display and show the parking aid alert display.
Parking Aid Alert Display



A visual interpretation of the detection areas is given in the TSD.

The visual interpretation dynamically updates as the sensors detect an objets within the set parameters. This feature can also
be used as a diagnostic aid.

In the combined mode, the sensors emit a series of ultrasonic impulses and then switch to receiver mode to receive the echo
reflected by an obstacle within the detection range. The received echo signals are amplified and converted from an analogue

signal to a digital signal by the sensor. The digital signal is passed to the parking aid module and compared with
pre-programmed data stored in an EEPROM (electrically erasable programmable read only memory) within the module. The
module receives this data via the signal line from the sensor and calculates the distance from the object using the elapsed
time between the transmitted and received impulse. The duration of the impulse duration is determined by the module, with
the sensor controlling the frequency of the impulse output.

In receiver mode, the sensor receives impulses that were emitted by adjacent sensors. The module uses this information to
precisely determine the position and distance of the object.

If no objects are detected there are no further warning tones. If an object is detected, repeated audible tones are emitted
from either the front or rear audio speakers as appropriate. The time delay between the tones decreases as the distance
between the object and the vehicle decreases, until at approximately 300 mm (12 inches), the audible tone becomes
continuous.

After the initial detection of an object, if there is no decrease in the distance between an object and the central sensors, the
time delay between the audible warnings remains constant. If an object is detected by one of the corner sensors only, the
audible warnings stop after approximately 5 seconds if there is no change in the distance between an object and the corner
sensor.

When approaching several objects within detection range, the control module recognises the distance from the vehicle to the
nearest object.

The PDC module will prioritise the objects detected, the nearest object detected will take priority and the corresponding audio
outputs will be emitted. For example if 2 objects are detected (one front one rear) the nearest detected object will take
priority and relevant audible tone will be heard.

If two objects are detected at equal distance (one front one rear) the audible tones will alternate between the front and rear
speakers.

If reverse (R) is the first gear selected after the ignition is switched on, both the front (if fitted) and rear parking aid sensors
will become operational. If a forward drive gear is subsequently selected, the front and rear parking aid sensors will remain
operational until vehicle speed increases above 16 km/h (10 mph), park (P) is selected or the PDC control switch is pressed.

If drive (D) is the first gear selected after the ignition is switched on the parking aid system will have to be activated by
pressing the PDC control switch.


NOTE: The PDC system can not be activated whilst the vehicle is in park (P).

The volume output of the parking aid audible tones can be adjusted by selecting the 'Vehicle Settings' menu and selecting
'Parking' from the menu on the TSD. The volume can be adjusted using the + or - selections on the TSD.

The system can detect when a trailer is connected to the vehicle by a message output on the medium speed CAN bus from the trailer module. When the parking aid module detects that a trailer is connected to the vehicle, the rear sensors are disabled to
prevent constant warnings due to the close proximity of the trailer.


NOTE: The ignition needs to be cycled once the trailer has been disconnected to activate the rear parking aid system.

1 Rear/Front Outer Approximately 600 mm (24 inches) Approximately 300 mm (12 inches) 2 Rear Inner Approximately 1800 mm (71 inches) Approximately 300 mm (12 inches) 3 Front Inner Approximately 800 mm (31 inches) Approximately 300 mm (12 inches) PARKING AID CAMERA

The parking aid camera receives an ignition power mode 6 power supply from the RJB. It also has a LIN (local interconnect network) bus connection from the RJB which is not used at the moment but installed for a later enhancement of the parking aid camera.

A shielded co-axial cable connection between the camera and the Touch Screen Display (TSD) is used for the video image
transmission.

The camera receives power at all times when the ignition is in power mode 6. When reverse gear is selected, the RJB transmits a reverse selected signal on the medium speed CAN bus message to the entertainment system control module. This message is transferred on the MOST to the TSD which displays the parking aid camera video input from the camera in
preference to the parking aid alert screen.

If the driver does not require the camera image in the TSD, a single touch on the screen will revert the display to the parking
aid alert screen. The camera view can be reselected by pressing the 'Rear Camera' softkey on the TSD.

When reverse gear is deselected, the camera image remains on the TSD for 10 seconds after the transmission has been put
into drive 'D'. This is to prevent the TSD switching between screens if the vehicle is being manoeuvred into a parking space. If
the vehicle forward speed exceeds 16 km/h (10 mph) within the 10 second period, the camera image is removed from the TSD.

If the TSD display is switched off, the camera image will be automatically displayed when reverse gear is selected. When
reverse gear is deselected and the 10 second period has expired, the TSD will revert back to its switched off state.



PARKING AID

Parking Aid Module Component Description

The parking aid module is located on the LH side of the luggage compartment.
The parking aid module has three connectors which provide for power, ground and CAN bus connections, front parking aid sensors and rear parking aid sensors. The medium speed CAN bus connections provide for the receipt of the following Distance Calculation

information from other systems:

ABS (anti-lock brake system) module - Road speed signal
TCM (transmission control module) - Reverse gear engaged signal
Trailer module - Trailer attached to vehicle

The module also outputs messages on the medium speed CAN bus which are received by the integrated audio module. The integrated audio module processes these messages and converts them into Media Orientated System Transport (MOST) signals
which are passed to the audio system power amplifier. These signals are then used by the power amplifier to emit the
applicable warning tones from the front or rear audio speakers when an object is detected by the front or rear parking aid
sensors. A warning tone can also be emitted to alert the driver to a fault in the parking aid system.

The control module has a diagnostic connection via the medium speed CAN bus to enable faults to be retrieved using the
Jaguar approved diagnostic equipment. Additionally an on-board diagnostic routine within the control module constantly
monitors the system and alerts the driver to a system fault by emitting a 3 second continuous tone through the rear audio
system speakers when the ignition is switched on. If front parking aid sensors are fitted, the control switch LED will also flash
6 times.
Parking Aid Sensors

Four ultrasonic sensors are located in the front (if fitted) and rear bumpers.

Each sensor has a three pin connector which mates with a bumper harness, which in turn is connected to the main body
harness. Three pins provide for power supply, ground and signal lines to and from the parking aid module.

The parking aid module controls the operation of each sensor using a digital output on the signal line. The module controls the
sensor in one of two modes; combined transmitter and receiver mode or receiver mode only.
Parking Aid Switch



The parking aid switch is located in the instrument panel switch pack, above the touch screen. The switch is the LH switch with an integral LED.
The switch is a non-latching push switch which allows the driver to select the parking aid system on or off. When pressed, the
switch momentarily connects a ground to the parking aid module.
The LED indicates when the parking aid system is active. The LED is controlled by the parking aid module.

NOTE: The control switch allows the driver to activate/deactivate the parking aid system if operation is required or not
required.

PARKING AID CAMERA

The parking aid camera receives an ignition power mode 6 power supply from the RJB. It also has a LIN bus connection with the RJB, which is used as a gateway. A shielded co-axial cable connection between the camera and the TSD is used for the video image transmission.

The camera receives power at all times when the ignition is in power mode 6. When reverse gear is selected, the RJB transmits a reverse selected message on the medium speed CAN bus. The information and entertainment module transfers the message on the MOST ring to the TSD, which displays the video input from the parking aid camera in preference to the parking
aid alert screen.

The display from the camera incorporates graphic overlays, indicating vehicle direction, width and proximity to surrounding
objects.

The camera view can be reselected by
pressing the Rear Camera soft key on the TSD.


NOTE: This can only be activated when reverse gear is selected.

When reverse gear is deselected, the camera image remains on the TSD for 2 seconds after the transmission has been put into
D (drive). If the vehicle forward speed in D exceeds 16 km/h (10 mph) the camera image is removed from the TSD.

If the TSD is switched off, the camera image will be automatically displayed when reverse gear is selected. When reverse gear
is deselected, after 10 seconds the TSD will revert back to its switched off state.

The dual battery system comprises the following components:
Dual Battery Module (DBM).
Dual Battery Junction Box (DBJB).
Gateway Module (GWM).
Primary battery.
Secondary battery.

The GWM hosts most of the software required to control the dual battery system and components. The GWM monitors the
components and can store fault related DTC's.

The GWM also controls the charging system software in conjunction with the ECM, RJB, CJB and ABS (anti-lock brake system) control module via the high speed and medium speed CAN (controller area network) bus. The GWM software will monitor the
status of the stop/start system and determine when a stop/start event can occur. It can also intervene to maintain vehicle
systems by keeping the engine running or initiating a restart due to, for example, climate control system requirements or
request for restart from the ECM. A brake pressure signal is received from the ABS control module which will indicate to the
GWM that an engine restart is required from driver operation of the foot brake.

The GWM contains the intelligent power management system and the BMS software. Monitoring of the primary battery
condition for stop/start is controlled by the GWM and the BMS control module.
