Parking Aid - Parking Aid - Overview
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.

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.

CAUTION: Diagnosis by substitution from a donor vehicle is NOT acceptable. Substitution of control modules does not
guarantee confirmation of a fault, and may also cause additional faults in the vehicle being tested and/or the donor vehicle.
NOTES:


If the control module is suspect and the vehicle remains under manufacturer warranty, refer to the Warranty Policy and
Procedures manual (section B1.2), or determine if any prior approval programme is in operation, prior to the installation of a
new module.


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. Parking aid system functioning correctly

NOTE: Under no circumstances should the battery be disconnected with the engine running because under these
conditions the generator can give a very high output voltage. This high transient voltage will damage the electronic
components in the vehicle. Loose or incomplete battery connections may also cause high transient voltage.
3. HEALTH AND SAFETY PRECAUTIONS

WARNINGS:


BATTERY CELLS CONTAIN SULPHURIC ACID AND EXPLOSIVE MIXTURES OF HYDROGEN AND OXYGEN GASES. IT IS
THEREFORE ESSENTIAL THAT THE FOLLOWING SAFETY PRECAUTIONS ARE OBSERVED.


Batteries emit highly explosive hydrogen at all times, particularly during charging. To prevent any potential form of
ignition occurring when working in the vicinity of a battery:
Do not smoke when working near batteries.
Avoid sparks, short circuits or other sources of ignition in the battery vicinity.
Switch off current before making or breaking electrical connections.
Ensure battery charging area is well ventilated.
Ensure the charger is switched off when: a) connecting to a battery; b) disconnecting from the battery.
Always disconnect the ground cable from the battery terminal first and reconnect it last.


Batteries contain poisonous and highly corrosive acid. To prevent personal injury, or damage to clothing or the vehicle,
the following working practices should be followed when topping up, checking electrolyte specific gravity, removal, refitting or
carrying batteries:
Always wear suitable protective clothing (an apron or similar), safety glasses, a face mask and suitable gloves.
If acid is spilled or splashed onto clothing or the body, it must be neutralized immediately and then rinsed with clean
water. A solution of baking soda or household ammonia and water may be used as a neutralizer.
In the event of contact with the skin, drench the affected area with water. In the case of contact with the eyes, bathe
the affected area with cool clean water for approximately 15 minutes and seek urgent medical attention.
If battery acid is spilled or splashed on any surface of a vehicle, it should be neutralized and rinsed with clean water.
Heat is generated when acid is mixed with water. If it becomes necessary to prepare electrolyte of a desired specific
gravity, SLOWLY pour the concentrated acid into water (not water into acid), adding small amounts of acid while
stirring. Allow the electrolyte to cool if noticeable heat develops. With the exception of lead or lead-lined containers,
always use non-metallic receptacles or funnels. Do not store acid in excessively warm locations or in direct sunlight.


Due to their hazardous contents, the disposal of batteries is strictly controlled. When a battery is scrapped, ensure it is
disposed of safely, complying with local environmental regulations. If in doubt, contact your local authority for advice on
disposal facilities.

9 CONFIRMING ELECTROLYTE LEVEL

WARNINGS:


BEFORE CHECKING AND TOPPING-UP THE BATTERY ELECTROLYTE, REFER TO THE HEALTH AND SAFETY PRECAUTIONS
SECTION.


AGM TECHNOLOGY BATTERIES ARE FULLY SEALED FOR LIFE AND NO ATTEMPT SHOULD BE MADE TO CHECK OR TOP UP
THE ELECTROLYTE LEVEL.
On certain types of battery the electrolyte level may need to be checked.

Make sure the battery is of a type suitable for topping up. These types of batteries will have cell plugs visible on the
top face of the battery or a removable access panel to allow access to the cells.
On batteries with a clear or opaque case and level marks, check the electrolyte level by visual inspection of the
maximum level indicator mark on the battery casing indicating adequate level above the battery separators.
On batteries with black cases, remove the cell plugs or access panel and ensure the electrolyte level is level with the
indicator in the cell hole. A flashlight may be required to see the electrolyte level on this type of battery.
If the electrolyte level is low, top-up using distilled water.


NOTE: Maintenance free and Valve Regulated (AGM) batteries are sealed and therefore cannot be topped up.
CAUTION: DO NOT overfill.
