Component Tests
Engine Oil Leaks
NOTE: Before installing new gaskets or oil seals, make sure that the fault is clearly established.
If the oil leak cannot be identified clearly by a visual inspection, carry out an Ultraviolet test:
Fluorescent Oil Additive Method
1. Clean the engine with a suitable cleaning fluid (brake cleaner).
2. Drain the engine oil and refill with recommended oil, premixed with Diesel Engine Oil Dye or equivalent. Use a minimum
14.8 ml (0.5 ounce) to a maximum 29.6 ml (1 ounce) of fluorescent additive to all engines. If oil is not premixed,
fluorescent additive must first be added to the crankcase.
3. Run engine for 15 minutes. Stop the engine and inspect all seal and gasket areas for leaks using a 12 Volt Master UV
Diagnostic Inspection Kit or equivalent. A clear bright yellow or orange area will identify leak. For extremely small
leaks, several hours may be required for the leak to appear.
4. As necessary, pressurize the main oil gallery system to locate leaks due to incorrectly sealed, loose or cocked plugs. If
the flywheel bolts leak oil, look for sealer on the threads.
5. Repair all leaks as necessary.
Compression Test General Remarks
NOTES:
Removing fuses and disconnecting electrical components may cause the Engine Control Module (ECM) to log Diagnostic
Trouble Codes (DTCs). After the measurements have been carried out, DTCs should be cleared from memory by connecting to
the Manufacturer Approved Diagnostic System.
Only check the compression pressure with the valves set to the prescribed clearance (if this can be adjusted).
The compression pressure should be checked with the engine at normal operating temperature.
Check the Compression Pressure
WARNING: Move gear selector lever to 'P' position. Failure to follow this instruction may result in personal injury.
1. Remove the fuel pump relay.
2. Start the engine - the engine will start, run for a few seconds then stall.
3. Remove the spark plugs.
4. Install the compression tester.
5. Install an auxiliary starter switch in the starting circuit. With the ignition switch OFF, using the auxiliary starter switch,
crank the engine a minimum of five compression strokes and record the highest reading. Note the approximate number
of compression strokes required to obtain the highest reading.
6. Repeat the test on each cylinder, cranking the engine approximately the same number of compression strokes.
7. Install the removed components in reverse order, observing the specified tightening torques.
8. Clear all DTCs from the ECM.
Interpretation of the Results
NOTE: Due to the possibility of loose carbon that has become trapped between the valve face and seat effecting the
pressure readings, when carrying out a compression test and cylinders are found to have low pressures, install the spark plugs,
road test the vehicle and re-test the suspect cylinders. If the correct pressures are restored, no further action is required.
The indicated compression pressures are considered within specification if the lowest reading cylinder is within 75% of the
highest reading.
If the cylinder pressures are found to be low, carry out a leakdown test to determine the location of the fault (if any leakback
can be heard through the engine breather system suspect the piston rings, if any leakback can be heard through the inlet
system suspect the inlet valve or seat, if any leakback can be heard through the exhaust manifold suspect the exhaust valve
or seat. If the measurements for two cylinders next to each other are both too low then it is very likely that the cylinder head
gasket between them is burnt through. This can also be recognized by traces of engine oil in the coolant and/or coolant in the

8. CAUTIONS:
Make sure that the area around the component is
clean and free of foreign material.
Make sure the working surfaces are thoroughly clean to
avoid contamination of the sensitive components.
Make sure that the valve grinding paste is kept away
from the valve stem.
Place a small amount of fine valve grinding paste
evenly around the contact face of the valve.
Place the valve in position and, using a suitable
valve grinding tool, rotate the valve back and forth a
few degrees on its seat, using light pressure.
Raise the valve frequently during lapping and turn it
into a new position after a few laps or rotations.
Lap only until a continuous but narrow lapping mark
is visible on both the valve seat and valve face.
Thoroughly clean all surfaces to remove traces of
valve grinding paste from the cylinder head, valve
seat and valve face.
Repeat steps 5 to 8 for the remaining valves.

Face Level Registers System Operation
Operation of the face level registers is controlled by the ATC module, using LIN bus messages to the integral stepper motors. The four registers operate together in both the opening and closing phases.
The face level registers can be selected to run in one of two modes; 'automatic' or 'always open'. The mode is selected on the
climate control screen of the TSD.
Refer to: Navigation System (415-01 Information and Entertainment System, Description and Operation).
In the automatic mode, operation of the face level registers is synchronized with the engine START/STOP button. When the
engine starts the ATC module opens the registers. When the engine stops, the ATC module closes the registers.
If a face level register is fouled, when it receives an open or close request, the register concerned makes a number of
attempts to reach the requested position. If the register still does not move, it is left in the fouled position. The remaining
registers will continue to open and close as normal.
The automatic mode is disabled when the climate control system is off. The ATC module closes the registers if they are open in the automatic mode and the climate control system is selected off.
Diagnostics
If a fault occurs with the face level registers, a DTC (diagnostic trouble code) is stored in the ATC module. The DTC can be read using the Jaguar approved diagnostic system. The Jaguar approved diagnostic system can also initiate a self test routine
to check the operation of the face level registers.
Refer to: Climate Control System (412-00 Climate Control System - General Information, Diagnosis and Testing).
Air Ducts Component Description
The air ducts distribute air from the heater assembly to the registers and vents in the instrument panel and the center floor
console. Air ducts also direct air from the heater assembly into the front and rear footwells.
Registers and Vents
The registers control the flow and direction of air from the air ducts. The instrument panel contains four face level registers;
one at each end and two mounted centrally. For the rear seat occupants, two registers are installed in the rear face of the
center floor console. All of the registers incorporate vertical and horizontal directional vane adjustment and full air flow
adjustment down to zero.
The four face level registers in the instrument panel each contain an integral stepper motor. The stepper motors enable the
registers to rotate between the open and closed positions. In the open position, the registers have normal appearance and
functionality. In the closed position, the registers present a smooth surface flush with the surrounding instrument panel.
The vents are fixed outlets. There are four vents in the upper surface of the instrument panel; one in each end to direct air
onto the side windows and two along the front edge to direct air onto the windshield.

Climate Control - Control Components - Overview
Description and Operation
Overview Published: 11-May-2011
The climate control system is controlled by the ATC (automatic temperature control) module. It controls the heating and
ventilation system and the A/C (air conditioning) system to regulate the temperature, volume and distribution of air into the
passenger compartment. The system is a fully automatic dual zone system capable of maintaining individual temperature
levels selected for the LH (left-hand) and RH (right-hand) sides of the passenger compartment, up to a maximum differential
of approximately 3 ºC (5.4 ºF). Manual overrides for the system include inlet air source, blower speed and air distribution.
These selections can be made using either the soft switches on the home and climate control screens of the touch screen
display (TSD), or the switches on the integrated control panel.
The ATC module also controls: The rear window heater.
The windshield heater (where fitted).
The exterior mirror heaters.
The seat heaters (where fitted).
The steering wheel heater.

rear window heater switch is pressed or the engine stops.
Automatic operation during a journey is initiated when low ambient air temperatures are experienced and the vehicle has been
travelling for a set period of time above a threshold speed. In this instance, no feedback is given to the driver to inform him
the rear window heater is operational (the switch LED is not illuminated). The duration of heater operation is variable depending on the ambient air temperature, vehicle speed and the amount of time the vehicle has been travelling.
Windshield Heater (Where Fitted)
Windshield heater operation is only enabled when the engine is running. The ATC module controls operation of the windshield heater using two relays in the EJB (engine junction box). When windshield heater operation is required, the ATC module broadcasts a message to the CJB on the medium speed CAN bus. On receipt of the message, the CJB energizes the relays by providing a ground path for both relay coils. This allows a battery feed to flow across the relays to power the windshield left
and right heater elements.
There are two modes of windshield heater operation; manual and automatic.
Manual operation is activated by pressing the windshield heater switch on the integrated control panel. When the switch is
pressed, the status LED in the switch illuminates and the windshield heater elements are energized. Manual operation is discontinued when the windshield heater switch is pressed a second time, 5 minutes have elapsed (the heating phase), or the
engine stops. If manual operation is discontinued by the engine stopping, the previous heating phase is resumed if the engine
is re-started within 30 seconds.
There are two variants of automatic operation; automatic operation at the start of a journey and automatic operation during a
journey.
Automatic operation at the start of a journey is initiated if the ambient air temperature is below 5 °C (41 °F). In this instance,
the switch LED is illuminated and the heater elements are energized for 6.5 minutes. Automatic operation is discontinued if the windshield heater switch is pressed or the engine stops.
Automatic operation during a journey is initiated when low ambient air temperatures are experienced and the vehicle has been
travelling for a set period of time above a threshold speed. In this instance, no feedback is given to the driver to inform him
the windshield heater is operational (the switch LED is not illuminated) and the duration of operation is variable depending upon the ambient air temperature, vehicle speed and the amount of time the vehicle has been travelling.
Exterior Mirror Heaters
Operation of the exterior mirror heaters is fully automatic and not controllable by the driver. Exterior mirror heater operation is
determined by ambient air temperature and windshield wiper status. When ambient air temperature reaches a pre-determined
level, the ATC module broadcasts an exterior mirror heating request to the door modules over the medium speed CAN bus. On receipt of this message, the door modules provide feed and ground connections to both exterior mirror heater elements.
The amount of time the exterior mirror heaters are operational increases if the windshield wipers are switched on. This ensures
the mirrors remain mist free in damp and wet conditions, where there is an increased risk of misting.
Seat Heaters (Where Fitted)
There are four seat heater settings available; off, 1, 2 and 3, which can be selected on the home and climate control screens
of the TSD. The heat setting is relayed to the vehicle occupants through a graduated display on the TSD.
Operation of the heated seats is controlled by the ATC module. When the ATC module receives a heating request from the TSD, it broadcasts a message to the CJB over the medium speed CAN bus. The CJB then provides a hardwired 12 V supply to the three heater elements in the related front seat. The heater elements, two in the seat cushion and one in the seat squab,
are wired in series. The ATC module monitors seat temperature using a temperature sensor located in each seat cushion. The CJB provides the temperature sensors with a 5 V supply. The level of the returned voltage back to the CJB is proportional to the seat temperature. The value of the return signal is broadcast to the ATC module, over the medium speed CAN bus, which allows it to control the seat temperature to the required level. The ATC module will suspend or disable operation of the seat heaters if any of the following occur:
Battery voltage exceeds 16.5 ± 0.3 V for more than 5 seconds. Seat heating is re-enabled when battery voltage
decreases to 16.2 ± 0.3 V.
If a short or open circuit is detected.
If the seat heat temperature rises significantly above the target temperature setting.
The graduated display on the TSD remains illuminated until the seat heaters are turned off or the engine stops. If the engine
is restarted within 30 seconds the seat heater resumes the previous heating level.

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

gage, odometer, trip distance and trip computer readouts. The trip distance and trip computer information is derived from
information supplied on the high speed CAN bus to the instrument cluster from the ABS module and the ECM.
The area above the message center displays the transmission gear position information and speed control related information.
The transmission information is supplied on the high speed CAN bus from the TCM (transmission control module).
NOTE: There is no engine coolant temperature gage displayed. If the engine coolant temperature increases to above a
predetermined threshold, a warning message is displayed in the message center. The message is sent from the ECM in a high speed CAN message to the instrument cluster.
TRANSMISSION GEAR SELECTION POSITION
The gear position display shows JaguarDrive selector position or selected gear when using the Jaguar Sequential Shift. The gear
selector module transmits a CAN message to the instrument cluster for gear selector lever position. The module also outputs a 'not in park' signal to the instrument cluster. The TCM transmits a high speed CAN message to the instrument cluster with data containing the selected gear when in Jaguar Sequential Shift mode.
