brake JAGUAR XFR 2010 1.G Workshop Manual

Item Description 1 Forward alert switch The forward alert system utilizes the adaptive speed control system components. Forward alert is turned on and off
independently of adaptive speed control, via a switch mounted in the lower outboard knee bolster switchpack. Forward alert
will notify the driver by means of a chime, a warning indicator in the instrument cluster and an indication in the message
center, when a target vehicle comes into range. The system will NOT use throttle or brake intervention to slow the vehicle.

The forward alert switch is connected to the instrument cluster in a resistive ladder with the luggage compartment opening
switch and the fuel filler flap switch. The instrument cluster sends the forward alert information to the Adaptive speed control
module on the CAN bus.

WARNING: The system is intended as a driver aid and should be used as such. The system is NOT a collision warning or
avoidance device.

The system sensitivity can be adjusted in the same manner as the adaptive speed control, via the steering wheel mounted
switches. Each adjustment is accompanied by a message in the message center. FORWARD ALERT SWITCHES

General Procedures


1. WARNING: Good ventilation is necessary in the area where A/C leak
testing is to be carried out. If the surrounding air is contaminated with
refrigerant gas, the leak detector will indicate this gas all the time.
Odors from other chemicals such as antifreeze, diesel fuel, disc brake
cleaner, or other cleaning solvents can cause the same problem. A fan,
even in a well ventilated area, is very helpful in removing small traces of
contamination from the air that might affect the leak detector. Failure to
follow this instruction may result in personal injury.

Attach an R-134a manifold gauge set or use a UL-approved
recovery/recycling device such as an R-134a A/C refrigerant center (which
meets SAE Standard J 1991). For additional information, refer to the
manufacturers equipment instructions.
Both gauges should indicate 413-551 kPa (60-80 psi) at 24°C
(75°F) with the engine off.
If little or no pressure is indicated, carry out the air conditioning
(A/C) system recovery, evacuation and charging procedure.
For additional information, refer to Air Conditioning (AC) System Recovery, Evacuation and Charging in this section.
2. Use an R134-a Automatic calibration halogen leak detector to leak test
the refrigerant system. For additional information, refer to the
manufacturers equipment instructions.

3. If a leak is found, carry out the air conditioning (A/C) system recovery
procedure.
For additional information, refer to Air Conditioning (AC) System Recovery, Evacuation and Charging in this section.

WARNING INDICATOR FUNCTIONALITY System Operation



Item Description 1 LH turn signal 2 RH turn signal 3 Brake warning 4 Brake warning (NAS) 5 Forward alert 6 Automatic Speed Limiter (ASL) 7 Adaptive speed control 8 ABS (anti-lock brake system) warning 9 ABS warning (NAS) 10 Malfunction Indicator Lamp (MIL) 11 Tire Pressure Monitoring System (TPMS) 12 Airbag warning 13 Front fog lamps 14 Dynamic Stability Control (DSC) warning 15 Seat belt warning 16 Side lamps 17 High beam 18 Rearfoglamps

The functionality for each of the above warning indicators is described in the following sections:

1 and 2. Turn Signal Indicators
The turn signal indicators are controlled by the CJB on receipt of medium speed CAN bus signals from the instrument cluster.
The instrument cluster outputs a voltage to the turn signal indicator switch. The switch contains resistors of different values.
When the switch is operated in either the LH or RH direction, the voltage is passed to a ground connection in the instrument cluster which detects the reduced voltage supplied via the resistors. When the turn signal indicator switch is operated in the
LH or RH direction, the instrument cluster detects the ground voltage and determines whether a LH or RH selection is made.
The instrument cluster transmits a medium speed CAN message to the CJB for operation of the applicable turn signal indicators. The message can contain a number of states for each possible switch position and also an out of range low and
high state for circuit faults and an initial value for the switch neutral position. The turn signal indicators are not subject to the
3 second indicator check when the ignition is switched on.

The RJB (rear junction box) software controls the flash rate of the warning indicator which sends 'ON' and 'OFF' signals to the
instrument cluster which flashes the indicators in a green color. During normal operation, the warning indicator flashes slowly,
accompanied simultaneously by a sound from the instrument cluster sounder. If a fault exists, the RJB transmits a message to the instrument cluster which responds by displaying an appropriate message in the message center.

The hazard warning indicators are controlled by the CJB on receipt of a completed ground path from the hazard warning indicator switch. The CJB outputs a medium speed CAN message to the instrument cluster which operates both the LH and RH turn signal indicators simultaneously. The hazard warning indicators can operate with the ignition switched off, therefore the
CAN message from the CJB will also carry a 'wake-up' message for the instrument cluster. 3. Brake Warning Indicator

This warning indicator is displayed in a red or amber color (dependant on market) as a brake symbol in all markets except
United States of America (USA) which have the word 'BRAKE' in place of the symbol. The indicator is controlled by high speed
CAN messages from the ABS module and the parking brake control module. The indicator is illuminated in a red color for a 3 second indicator check when the ignition is switched on.

The instrument cluster monitors the fluid level in the brake fluid reservoir using a hardwired level switch. If the fluid level falls
to below a determined level, the switch contact is broken and the ABS module detects the low fluid level condition. The instrument cluster illuminates the warning indicator and simultaneously displays a 'BRAKE FLUID LOW' message in the
message center.


NOTE: If both the brake warning indicator and the ABS warning indicator illuminate simultaneously, a major fault in the brake system will have occurred.

The warning indicator also displays parking brake status. When the parking brake is applied, the warning indicator will be
illuminated by the instrument cluster and, if the vehicle is moving, the message 'PARK BRAKE APPLIED' will be also displayed
in the message center in response to a CAN message from the parking brake control module.
If a condition exists where the parking brake cannot be applied, the parking brake control module issues a CAN message to the instrument cluster which flashes the warning lamp on and off and is accompanied with a message 'CANNOT APPLY PARK BRAKE'.
If a fault occurs in the parking brake system, the parking brake control module issues a CAN message to the instrument cluster which illuminates the warning indicator and displays the message 'PARK BRAKE FAULT' in the message
center.
4. Forward Alert Indicator

The forward alert system uses the components of the adaptive speed control system to alert the driver of the presence of a
vehicle ahead. The system can be turned on and off using a switch located in the auxiliary lighting switch when the adaptive
speed control system is off. The indicator is illuminated in an amber color for a 3 second indicator check when the ignition is
switched on.

The forward alert system is controlled by the adaptive speed control module. When the switch is pressed, the forward alert
system is activated and the adaptive speed control module issues a forward alert active message on the high speed CAN bus to the instrument cluster. The forward alert icon in the instrument cluster will illuminate in an amber color and a 'FORWARD
ALERT' message will be displayed in the message center. When the button is pressed a second time, the module issues a
forward alert off CAN message. The forward alert system will be deactivated, the forward alert icon will go off and a message 'FORWARD ALERT OFF' will be displayed in the message center.
5. Automatic Speed Limiter (ASL) Indicator

The ASL is controlled by the ECM (engine control module). An ASL switch is located in the floor console, adjacent to the gear
selector lever. When the ASL switch is pressed, this is sensed by the ECM which issues a high speed CAN message to the instrument cluster. The instrument cluster illuminates the ASL warning indicator in an amber color to show the driver that ASL
is active. The driver sets the required speed using the speed control SET +/- switches on the steering wheel. The selected
speed is shown by the message ' LIMITER SET XXX MPH / K/MH' in the message center. The indicator is illuminated in an
amber color for a 3 second indicator check when the ignition is switched on. ASL can be deselected by pressing the ASL switch,
by depressing the throttle pedal initiating kick-down or by pressing the 'cancel' switch on the steering wheel. The ASL indicator
will go off and the message center will display the message 'limiter cancelled' for 4 seconds. If a fault occurs in the ASL
system, the ECM will send a message to the instrument cluster to illuminate the ASL indicator and display the message 'LIMITER NOT AVAILABLE'.

6. Adaptive Speed Control Indicator
The adaptive speed control system is controlled by the adaptive speed control module. Operation of the SET +/- switches on
the steering wheel will activate the system. Operation of the switches is detected by the adaptive speed control module. The
module issues a high speed CAN message to the instrument cluster which illuminates the adaptive speed control indicator, when the system is in 'follow mode', in an amber color and displays a 'SETSPEED XXX MPH / KM/H' message in the message
center. The indicator is illuminated in an amber color for a 3 second indicator check when the ignition is switched on.
7. Anti-lock Braking System (ABS) Warning Indicator

The ABS warning indicator is controlled by the ABS module. If a fault in the ABS system is detected by the ABS module, the module issues a high speed CAN message to the instrument cluster to illuminate the ABS warning indicator in an amber color and display the message 'ABS FAULT' in the instrument cluster. The indicator is illuminated in an amber color for a 3 second
indicator check when the ignition is switched on. If a fault is present when the ignition is on, the bulb will remain illuminated
after the 3 second indicator check period.
NOTES:


The 'ABS FAULT' message is not displayed in NAS markets).


If both the ABS warning indicator and the brake warning indicator illuminate simultaneously, a major fault in the brake system will have occurred.

On NAS vehicles, the ABS warning indicator is also used for parking brake operation. The NAS warning indicator does not have 'ABS' on the icon and will function as described previously for the parking brake operation of the brake warning indicator.
8. Engine Malfunction Indicator Lamp (MIL)

The MIL warning indicator is controlled by the ECM and illuminated by the instrument cluster on receipt of a message on the high speed CAN bus from the ECM. The indicator is illuminated in an amber color for a 3 second indicator check when the ignition is switched on.

If the MIL remains illuminated after the engine is started or illuminates when driving, a fault is present and must be
investigated at the earliest opportunity. Illumination of the MIL warning indicator alerts the driver to an OBD (on-board
diagnostic) fault which will cause excessive emissions output. This may relate to either an engine management system fault or
a transmission.
9. Tire Pressure Monitoring System (TPMS) Warning Indicator

The TPMS warning indicator is illuminated by the instrument cluster on receipt of a medium speed CAN message from the TPMS module. The indicator is illuminated in an amber color for a 3 second indicator check when the ignition is switched on.

If the indicator illuminates and is accompanied by the message 'TYRE PRESSURE SYSTEM FAULT' in the message center, then a
TPMS fault has occurred. If the indicator illuminates and accompanied by a different message, then a low tire pressure has
been detected, a spare wheel has been fitted or a TPMS sensor has failed.
10. Airbag Warning Indicator

The airbag warning indicator is controlled by the instrument cluster. The indicator is illuminated in an amber color for the 3
second indicator check when the ignition is switched on. The indicator remains illuminated after the 3 second period has
expired until the instrument cluster receives a turn off message on the high speed CAN bus from the RCM (restraints control module).
11. Front Fog Lamp Indicator

The green colored front fog lamp indicator is controlled by the CJB and illuminated by the instrument cluster on receipt of a front fog lamp on message on the medium speed CAN bus from the CJB. The indicator is illuminated for as long as the front fog lamps are active. The front fog lamp indicator is not subject to the 3 second indicator check when the ignition is switched
on.
12. Dynamic Stability Control (DSC) Indicator

The DSC warning lamp is controlled by the ABS module and illuminated by the instrument cluster in response to messages received on the high speed CAN bus. The indicator is illuminated in an amber color for the 3 second indicator check when the ignition is switched on. The DSC warning indicator, are permanently illuminated in an amber color if the instrument cluster
receives a high speed CAN message from the ABS module relating to one of the following faults:
Traction control fault
Yaw control fault
Engine drag torque control fault
Panic Brake Assist (PBA) fault
Signal missing relating to either traction control active, yaw control active or DSC switch input.

The above faults will also generate an applicable DSC and ABS warning message in the message center. The DSC warning
indicator will flash at 2 Hz for if the traction control or yaw control is active when the DSC system is enabled. If the DSC
system is switched off, the warning indicator will be permanently illuminated until the DSC system is subsequently
re-activated.

13. Safety Belt Warning Indicator

The safety belt warning indicator operates for both the driver and passenger safety belts. The warning indicator is controlled by

Item Description 1 Speedometer 2 ABS indicator (NAS) 3 ABS indicator (ROW) 4 Adaptive speed control indicator 5 Tachometer 6 Malfunction Indicator Lamp (MIL) 7 Tire Pressure Monitoring System (TPMS) indicator 8 Airbag warning indicator 9 Front fog lamp indicator 10 RH turn signal indicator 11 Rear fog lamp indicator 12 Dynamic Stability Control (DSC) indicator 13 High beam indicator 14 Seat belt warning indicator 15 Side lamp indicator 16 Message center 17 Automatic Speed Limiter (ASL) indicator 18 Forward alert indicator 19 Brake warning indicator (NAS) 20 Brake warning indicator (ROW) 21 LH turn signal indicator The warning indicators are located in various positions in the instrument cluster. The indicators can be split into two groups;
instrument cluster controlled and externally controlled.

Instrument cluster controlled warning indicators are dependent on software logic within the instrument cluster for activation.
The cluster software controls the indicator illumination check at ignition on (power mode 6).

Externally controlled indicators are supplied with current from another vehicle system control module or illuminated by the
instrument cluster software on receipt of a bus message from another vehicle sub-system. The indicator illumination check at
ignition on (powermode 6) is also controlled by the sub-system module for these indicators.
