Warning Devices - Blindspot Monitoring System - Overview
Description and Operation

OVERVIEW Published: 11-May-2011

Eliminating blind spots is a major element in vehicle body design, but because of the structural requirements of B, C and D
posts, blind spots cannot be entirely eliminated. Statistics show that some accidents are directly attributable to drivers moving
across into the path of overtaking vehicles that have not been seen in conventional mirrors. New mirror designs have improved
the situation, but by remotely covering areas that cannot be seen either directly or by the vehicle mirrors, have led to the
introduction of a radar-based blind spot monitoring system.
The blind spot monitoring system comprises:

LH (left-hand) Blind spot monitoring sensor
RH (right-hand) Blind spot monitoring sensor
LH door mirror RH door mirror
The system uses two radar modules operating at a frequency of 24 GHz and each combining the radar face and electronic
module in a single unit. The modules are located behind the rear bumper surface, symmetrically, one on each side of the car
behind the rear wheels. They are side facing and inclined rearwards at an angle of 16 degrees, which is dictated by the shape
at the rear of the vehicle. Each module is calibrated to detect a vehicle in the driver’s blind spot. Once a vehicle is detected
the module illuminates an amber warning ‘alert icon’ LED (light emitting diode) in the relevant exterior door mirror. If there is a
fault or blockage with the blind spot monitoring system an amber warning indicator dot LED is displayed in the exterior mirror and the message ‘blind spot monitoring not available’ is displayed in the instrument cluster message center.

When the system initiates, it performs a self-check, during which the warning icons in the mirrors illuminate alternately for a
short period of time. Each module does a left/right determination check when the ignition is switched on. Each mirror has a
different circuit configuration so that the modules can determine which mirror they are connected to. If a module detects the
wrong mirror it will go into a fault condition.

The blind spot monitoring modules receive vehicle speed on the medium speed CAN (controller area network) and are inactive
until the vehicle reaches 16kph (10mph). Each blind spot monitor module emits a radar field greater than the blind spot area.

Each Blind Spot Monitor module emits a radar field greater than the blind spot area. The actual blind spot area is calibrated
into the module during its manufacture.


CAUTION: The blind spot monitoring system is designed as a driver aid not a safety device. The driver should always
exercise due care and attention whilst driving. www.JagDocs.com

Generic scan tools may not read the codes listed, or may read only five digit codes. Match the five digits from the scan
tool to the first five digits of the seven digit code listed to identify the fault (the last two digits give additional information
read by the manufacturer approved diagnostic system).


When performing voltage or resistance tests, always use a digital multimeter (DMM) accurate to three decimal places,
and with an up-to-date calibration certificate. When testing resistance always take the resistance of the DMM leads into
account.


Check and rectify basic faults before beginning diagnostic routines involving pinpoint tests.


Inspect connectors for signs of water ingress, and pins for damage and/or corrosion.


If DTCs are recorded and, after performing the pinpoint tests, a fault is not present, an intermittent concern may be the
cause. Always check for loose connections and corroded terminals.


When carrying out repair/diagnosis of the system, on removal of the front or rear bumper inspect the sensor connectors
to ensure they were correctly latched and check fly leads for signs of chaffing or trapped wires.


Check DDW for open campaigns. Refer to the corresponding bulletins and SSMs which may be valid for the specific
customer complaint and carry out the recommendations as required

Description and Operation

OVERVIEW Published: 11-May-2011

The parking aid system provides an audible warning to the driver when any obstacles are in the path of the vehicle during a
forward (if front sensors are fitted) or reversing manoeuver. The purpose of the system is to assist the driver when parking or
manoeuvring in a restricted space. It is not designed as a crash avoidance system or a replacement for visual interpretation by
the driver.

All vehicles are fitted with rear parking aid sensors. Higher specification vehicles may also be fitted with front parking aid
sensors.
A roof console mounted parking aid switch allows the driver to deactivate the parking aid system if operation is not required.


NOTE: The switch is only fitted to vehicles with front parking aid sensors.

A parking aid camera is a standard fitment on some models and optional on others. The parking aid camera supplements the
information provided by the parking aid system by providing the driver with a visual display of the area directly behind the
vehicle.

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
www.JagDocs.com

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.
