out CAN network integrity tests using the
1 LH door mirror 2 Ambient air temperature sensor The ambient air temperature sensor is a NTC thermistor that provides the ATC module with an input of external air temperature. The sensor is hard wired to the ECM and its signal is transmitted to the instrument cluster on the high speed CAN bus. The instrument cluster acts as a gateway and transmits the ambient air temperature signal to the ATC module on the medium speed CAN bus. The sensor is installed in the LH door mirror, and is accessed by removing the mirror glass, cap and actuator.
Sunload Sensor
The sunload sensor consists of two photoelectric cells that provide the ATC module with inputs of light intensity; one as sensed coming from the left of the vehicle and one as sensed coming from the right. The inputs are a measure of the solar
heating effect on vehicle occupants, and are used by the ATC module to adjust blower speed, temperature and distribution to improve comfort.
The sensor is installed in the speaker grill on the upper surface of the instrument panel. Power for the sensor is provided by a
5 V feed from the instrument cluster.
The sensor also contains the active anti-theft alarm indicator.

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'.
the RCM and illuminated by the instrument cluster on receipt of high speed CAN bus messages. The safety belt warning indicator is not subject to the 3 second indicator check when the ignition is switched on.
The operation of the passenger seat buckle switch is as described below with the exception that the instrument cluster must
receive a hardwired signal from the belt minder control module to indicate that a passenger is occupying the seat.
The safety belt warning indicator is subject to a timer. The warning indicator is activated when the following conditions exist:
Ignition is switched on
One of the front seat belts is unbuckled
USA market only - 75 seconds has elapsed after ignition on mode is selected
Vehicle is not in reverse gear
Vehicle speed is more than 8 km/h (5 mph).
Once the above parameters are met, the instrument cluster flashes the warning indicator at 2 Hz for 10 seconds accompanied
by a simultaneous chime. After 10 seconds the chime ceases and the warning indicator is permanently illuminated for 20
seconds. This sequence is repeated every 30 seconds until one of the following events occurs:
300 seconds has elapsed
The safety belt of the occupied front seats is fastened
The ignition is switched to off mode
The vehicle speed decreases to below 5 km/h (3 mph).
NOTE: On USA market vehicles, the warning indicator in not permanently illuminated.
The safety belt minder function cannot be disabled. The seat belt minder function can be disabled.
Refer to: Safety Belt System (501-20A Safety Belt System, Description and Operation). 14. Side Lamp Indicator
The instrument cluster controls the green colored side lamp indicator on receipt of a side lamp status message on the medium
speed CAN bus from the CJB and the auxiliary junction box. The lighting switch on the LH steering column multifunction switch is connected to the instrument cluster. Selections using this switch are detected by the cluster which requests the side or
headlamp operation via a message to the CJB and the RJB. The CJB and the RJB responds with a side lamp active message and the cluster illuminates the side lamp indicator. The side lamp indicator is not subject to the 3 second indicator check when
the ignition is switched on.
15. High Beam Indicator
The instrument cluster controls the blue colored high beam indicator on receipt of a high beam status message on the medium
speed CAN bus from the CJB. The lighting switch on the LH steering column multifunction switch is connected to the instrument cluster. High beam or flash selections using this switch are detected by the cluster which requests the light
operation via a CAN message to the CJB. The CJB responds with a high beam active message and the cluster illuminates the high beam indicator. The high beam indicator is not subject to the 3 second indicator check when the ignition is switched on.
16. Rear Fog Lamp Indicator
The amber colored rear fog lamp indicator is controlled by the auxiliary junction box and illuminated by the instrument cluster
on receipt of a rear fog lamp on message on the medium speed CAN bus from the RJB. The indicator is illuminated for as long as the rear fog lamps are active. The rear fog lamp indicator is not subject to the 3 second indicator check when the ignition is
switched on.
SPEEDOMETER
The speedometer is driven by high speed CAN signals transmitted by the ABS module. The wheel speeds are measured by sensors reading the rotational speed of the rear wheels from toothed targets on the hubs. An average of the two wheel speeds
are passed from the sensors to the ABS module in the form of pulsed signals. The ABS module converts these signals into a speed output on the high speed CAN to the instrument cluster. The same speed outputs from the wheel speed sensors are also used to calculate the distance the vehicle has travelled.
TACHOMETER
The tachometer is driven by an engine speed signal transmitted on the high speed CAN from the ECM. The signal is derived from the CKP (crankshaft position) sensor. The signal is received by the instrument cluster microprocessor and the output from
the microprocessor drives the tachometer.
FUEL GAGE
The fuel gage is controlled by CAN messages from the RJB. The RJB reads the values output by the fuel level sensors every 131 ms and transmits a fuel tank contents value, corrected for battery voltage, in a CAN message to the instrument cluster. A fuel pump symbol is displayed to the left of the linear gage. An arrow above the symbol shows the driver on which side of the
vehicle the fuel filler cap is located. Above the linear fuel gage, is a LCD (liquid crystal display) area which displays odometer
and trip readouts. When a trip computer function is selected, these are replaced by a trip computer display for the trip function
selected.
LIQUID CRYSTAL DISPLAY
In the area above and below the message center is a LCD display. The area below the message center displays a linear fuel www.JagDocs.com
MESSAGE CENTER
The message center is a LCD located in a central position in the cluster. The message center displays system status information.
Refer to: Information and Message Center (413-08 Information and Message Center, Description and Operation).
ANALOGUE GAGES
Speedometer
The analogue speedometer is located on the LH side of the instrument cluster and is available in 4 market variants: Major scale Miles Per Hour (MPH), minor scale kilometers per hour (km/h) (ROW)
Major scale MPH, minor scale km/h (NAS)
Major scale km/h, minor scale MPH
Major scale km/h only.
Tachometer
The analogue tachometer is located on the RH side of the instrument cluster. The tachometer has different Revolutions Per Minute (RPM) scales depending on the engine variant fitted to the vehicle as follows:
4.2L V8 Naturally aspirated 8000 RPM (NAS Only)
5.0L V8 Naturally aspirated 8000 RPM
5.0L V8 Supercharger 8000 RPM
3.0L V6 Naturally aspirated 8000 RPM
3.0 V6 Diesel 6000 RPM.
ELECTRONIC GAGES
Fuel Gage
The linear fuel gage has a colored bar which moves left or right depending on the tank contents. As the bar moves to the left
the fuel tank contents displayed is decreasing. A warning message is displayed in the message center when the fuel tank
contents fall to below the reserve level.
Transmission Gear Position Display
The gear position display shows the JaguarDrive selector position or the selected gear when using the Jaguar Sequential Shift.
The applicable drive letter is highlighted to show that a selection has been made using the JaguarDrive selector.
When Jaguar Sequential Shift is selected, the letters change to numbers; 1 - 6, and the selected gear is highlighted to
emphasize the selection to the driver.
