brake sensor JAGUAR XFR 2010 1.G Repair Manual

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.

Halogen Low/high Beam Headlamp

The halogen low/high beam headlamp uses a projector lens, similar to the xenon headlamp. The projector module comprises
an ellipsoidal lens and a reflector. The projector reflector collects the light produced by the halogen bulb and projects the light
into a focal plane containing a shield. The contour of the shield is projected onto the road by the lens. The low/high beam
bulbs are quartz halogen and are retained in the headlamp unit with conventional wire retaining clips.

A tourist lever mechanism is located on the right hand side of the projector module. This mechanism moves a flap to blank off
a portion of the beam spread to enable the vehicle to be driven in opposite drive hand markets without applying blanking
decals to the headlamp lens. The beam is changed by removing the access cover at the rear of the lamp assembly and moving
a small lever located near the bulb holder, at the side of the projector.
Halogen High Beam Headlamp - Xenon and Halogen
The xenon and halogen headlamps use a complex surface reflector for the halogen fill in high beam lamp only lighting unit,
which is of the same design on both headlamp types. This type of reflector has the reflector divided into separate parabolic
segments, with each segment having a different focal length.

The high beam headlamp bulbs are quartz halogen and are retained in the headlamp unit with conventional wire retaining
clips.
Cornering Lamps


NOTE: The cornering lamps are not fitted to NAS vehicles.

The cornering lamps are an optional feature designed to illuminate the direction of travel when cornering at low speeds. The
design of the lens projects a spread of light from the vehicle at approximately 45 degrees to the vehicle axis. The cornering
lamp is incorporated into the headlamp assembly and shares the same housing as the low beam headlamp. The cornering lamp
uses a 35W Halogen H8 bulb which is permanently located in an integral holder which is connected on the headlamp housing.
The holder is located in an aperture in the headlamp housing and rotated to lock. The bulb is accessible via a removable cover
on the base of the headlamp housing.

The cornering lamps are controlled by the LH steering column multifunction switch with the lighting control switch in the headlamp position and the ignition in power mode 6. The cornering lamps are supplied power via the ignition circuit to ensure
that they do not function with the headlamp delay feature. The cornering lamps are deactivated if the vehicle speed exceeds
25 mph (40 km/h). Only one cornering lamp will illuminate at any one time. If the left hand turn signal indicators are selected
on, the left hand cornering lamp will be illuminated and vice versa, providing the vehicle speed and lighting control switch
positions are correct.
Static Bending Lamps


NOTE: The static bending lamps are not fitted to NAS vehicles.

The static bending lamps are designed to illuminate the direction of travel when cornering at low speeds. The static bending
lamp functionality, which is controlled by the CJB and the headlamp leveling module, operates using inputs from the steering angle sensor and vehicle speed information from the ABS (anti-lock brake system) module. The static bending lamp is
incorporated into the headlamp assembly and shares the same housing as the low beam headlamp. The design of the lens
projects a spread of light from the vehicle at approximately 45 degrees to the vehicle axis. The static bending lamp uses a
35W Halogen H8 bulb which locates in a holder which is connected via wires to the main connector on the headlamp housing.
The holder is located in an aperture in the headlamp housing and rotated to lock. The bulb is accessible via a removable cover
at the rear of the headlamp housing.

The static bending lamps operate with a steering angle sensor CAN bus signal which is received by the CJB. The CJB monitors this signal and vehicle speed and activates the static bending lamp bulb. When the operation parameters of the lamp are
reached, the CJB fades the static bending lamp bulb on using a PWM (pulse width modulation) voltage over a period of approximately 2 seconds. When the lamp is switched off, the CJB fades the bulb off by decreasing the PWM voltage in a linear manner depending on steering angle and vehicle speed. The cornering lamps can only be active for a maximum of 3 minutes.


NOTE: Static bending lamps only operate when the transmission is in DRIVE or in SPORT.

Turn Signal Indicators

The turn signal indicator lamp is incorporated into the outer part of the headlamp assembly. The turn signal indicator lamp
uses a PY21W bayonet orange colored bulb in ROW markets, a S8W 27/7W wedge bulb is used in NAS markets. The bulb is
fitted into a holder which connects with contacts in the headlamp housing. The holder is fitted into an aperture in the
headlamp housing and rotated to lock into position.

When active, the turn signal indicator lamps will flash at a frequency cycle of 380ms on and 380ms off. If a bulb fails, the
remaining turn signal lamps bulbs continue to flash at normal speed. The turn signal indicators in the instrument cluster will
flash at double speed to indicate the bulb failure to the driver.
Side Lamps

The side lamp is located between the headlamp projector module and the high bean headlamp. The side lamp uses a W5W
wedge fitting bulb which locates in a holder which connected via wires to the main connector on the headlamp housing. The
holder is a push fit into a receptacle in the headlamp housing. The bulb is accessible by removal of the inner cover on the rear
of the headlamp housing. Access to the bulb requires removal of the headlamp from the vehicle. The side lamps are operated
by selecting side lamps or headlamps on the lighting control switch. The side lamps are functional at all times and are

Description and Operation



CENTRAL JUNCTION BOX (CJB) System Operation

The CJB (central junction box) controls the operation of the DRL (daytime running lamps). The DRL are activated once the CJB detects an ignition on power mode 6 signal.
The CJB also monitors the lighting control switch and the auto lamps feature and overrides the DRL if required.


DAYTIME RUNNING LAMPS - CANADA Component Description

The DRL for this market use full intensity low beam headlamps. The side marker lamps, tail lamps and license plate lamps will be on, but instrument cluster illumination will be off. DRL are active when the following parameters are met:
PARK is not selected on the electronic transmission selector
Electronic Parking Brake (EPB) is off
Power mode 6 (ignition on) detected by the CJB The CJB receives an engine running signal The lighting control switch is in the off or side lamps position.
NOTES:


If the lighting control switch is moved to the headlamp position, DRL are deactivated and normal side lamp and headlamp functionality is operational.


When DRL are active, the headlamp flash function using the left hand steering column multifunction switch will operate normally.

The high beam headlamp function using the left hand steering column stalk switch will be deactivated. When the transmission
is in PARK, DRL are turned off. This is to reduce battery discharge during long periods of engine idling in cold climate conditions. When the electronic transmission selector is moved from the PARK position, normal DRL functionality is restored.
DAYTIME RUNNING LAMPS - DENMARK, HOLLAND, NORWAY, SWEDEN, FINLAND AND POLAND


NOTE: DRL for Poland is on vehicles from 2008MY.

CAUTIONS:


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


When probing connectors to take measurements in the course of the pinpoint tests, use the adaptor kit, part number
3548-1358-00
NOTES:


If the control module or a component 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/component


Generic scan tools may not read the codes listed, or may read only 5-digit codes. Match the 5 digits from the scan tool to
the first 5 digits of the 7-digit code listed to identify the fault (the last 2 digits give extra information read by the
manufacturer-approved diagnostic system)


When performing voltage or resistance tests, always use a digital multimeter accurate to three decimal places and with a
current calibration certificate. When testing resistance, always take the resistance of the digital multimeter 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 diagnostic trouble codes 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


Where an 'on demand self-test' is referred to, this can be accessed via the 'diagnostic trouble code monitor' tab on the
manufacturers approved diagnostic system


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

Wiring Harnesses - Wiring Harness
Description and Operation

Introduction Published: 21-Jan-2014

CAUTION: Do not use any other heat shrink sleeve other than the approved glue lined heat shrink sleeve mentioned in
the repair procedure.

The purpose of this document is to promote quick and efficient minor repair to harness connectors or cables using approved
methods. Repairs may only be made to cables and connectors which have been mechanically, not electrically damaged. It also
applies where the whole extent of the damage can be clearly identified and rectified.
Care and neatness are essential requirements in making a perfect repair.

Caution:

This harness repair guide, does not approve repairs to any of the following circuits:
1. Any media orientated system transport network harnesses.
2. Supplement restraint system (SRS) firing circuits (Air bags).
3. Link lead assembles, which are unique to safety critical circuits such as anti-lock brake system (ABS) and thermocouple
circuits. An example of this is the ABS wheel speed sensors with moulded connectors.
4. 4. Screened cables, leads and wiring harness(s).

If any harness(s) with defective electrical connector terminals or wires from the above circuits are a concern, new
components must be installed.

Repair Components


CAUTION: Where the repair procedure indicates that a glue lined heat shrink sleeve should be applied, apply sufficient
heat to the glue lined heat shrink to melt the glue in order to provide a water tight seal. Do not over heat the glue lined heat
shrink sleeve so that the wiring harness insulation becomes damaged.
The wiring harness repair components comprises:

Pre-terminated wiring harness(s) of different sizes and types
Three sizes of butt splice connectors
A selection of colored cable identification sleeves
Two sizes of glue lined heat shrink sleeves
A suitable heat source, for shrinking heat shrink sleeves will be required.

The pre-insulated diamond grip range of electrical connector terminals and in-line, butt splice connectors are the only
acceptable product for the repairs of wiring harnesses. The butt connectors not only grip the wire but also the insulation,
making a very secure joint.

If an electrical connector terminal is not available approval for the repair is NOT given and in these circumstances a new wiring
harness must be installed.

Pre-Terminated Wiring Harness(s) and Butt Splice Connectors

The pre-terminated wiring harness(s) are supplied with the insulation in one of three colors, red, blue or yellow. The colors do
not apply to any particular circuit but to the harness wire size. See the Relationship Table in the Repair Method section.

Butt splice connectors are also supplied with red, blue or yellow coverings, which must be matched to the pre-terminated
wiring harness insulation color.
