Check the Starter Relay circuit.


NOTE: On petrol engine variants, due to Smart Start, both sides of Relay Coil are switched directly from ECM (If
conditions correct). On diesel engine variants the low side only is switched directly from the ECM.
Check that the Steering Column Lock correctly operates and the steering wheel can turn freely.

Check that the High Speed CAN network is not malfunctioning, i.e. the CAN circuit is open or short circuit. This would mean
that the instrument cluster and ECM would be unable to communicate resulting in no Challenge being performed to enable the
ECM. This would be supported by LED Flash Code 24, see PATS Fault Code Table.

Also check the CAN network between the ABS module and the CJB. The CJB uses the CAN_BrakePressureTMC signal to
determine if the brake pedal has been pressed in order to allow an engine crank. The CJB uses a value of 0x05, if the CJB sees
a value less than this, it will not enable the Crank Request Output.
Engine cranks but will not start

If the Engine is cranking it means that the ECM has passed the authorisation required with the Instrument Cluster. If this
authorisation failed, the ECM would not engage the starter relay. This could be confirmed by verifying the PATS LED prove out
(illuminated solid for 3 seconds) or by reading DTCs from the instrument cluster and ECM.

In this case, the fuel pump circuit should be verified. The Fuel Pump Delivery Module (FPDM), which is supplied via the RJB
(authentication required with the instrument cluster) and controlled by the ECM, supplies the fuel pump.
In all cases of suspected non-start issues, the most logical failure modes should be eliminated first. i.e.

1. Check all relevant supplies and grounds to the relevant modules listed herein.
2. Note any unusual behaviour from other systems/functionality.
3. Note any functions that are not operating as expected.
PATS Fault Codes

For the various PATS modes/faults listed in the table , the instrument cluster will store a DTC and indicate this to the customer
during the detection period defined in the 'when logged' column, by illuminating the indicator as described for 60 seconds and
then flashing the LED 10 times as appropriate. The indication will stop immediately the ignition status is set to OFF any time
during the fault indication sequence. Up to 4 DTCs could be stored per key read sequence (1-10 read attempts). No DTCs will be
stored until all retry attempts are complete. Only the highest priority fault code will be flashed.

To determine the fault code from the LED: The LED will flash initially ten times with 1.5 seconds between. The LED will remain
OFF for 2.5 seconds then flash a number of times with 0.5 seconds between (the number of times the LED flashes represents
the first digit of the code), the LED will remain OFF for 1.5 seconds then flash a number of times with 1.5 seconds between
(the number of times the LED flashes represents the second digit of the code).

The PATS LED will be commanded on as shown under 'indication'. Normal PATS operations are complete within 400ms of the
ignition switch transition from OFF to ON or START, worst case for ECM communication problems will be less than 2 seconds. If
PATS is not complete during the 2 seconds the ECM will terminate PATS and await the next ignition ON or START event. PATS
faults will be indicated via the LED as soon as possible and will terminate the LED prove out. At ignition OFF all previous
flashing will cease and the perimeter anti-theft system will control the LED when the vehicle is locked and armed.

DTC Index


CAUTION: 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 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.


When carrying out repair/diagnosis of the system, on removal of the front or rear bumper inspect the sensor connectors
to ensure they were correctly latched and check fly leads for signs of chaffing or trapped wires.

HEATED SEATS - OPERATION

Heated Front Seats System Operation

The TSD receives a fused power supply from the RJB. One of the 3 seat heat temperature selections made by the driver or passenger using the TSD soft keys are passed from the TSD on the MOST ring to the Information and Entertainment module.
The information and entertainment module processes the information and transmits the request on the medium speed CAN bus to the ATC module.
The cushion heaters have a thermal sensor which supplies a feed back signal back to the CJB. The squab heater elements do not have a thermal sensor and are maintained at the same temperature as the seat cushion elements.

The ATC module reacts to the driver request information received from the information and entertainment module and requests the CJB to activate the seat heaters. The CJB measures the returned temperature signals from the thermal sensors and relays the temperature signals back to the ATC module. The ATC module then uses the measured seat element temperatures to provide closed-loop control of the heater elements to maintain the temperature at one the 3 heat ranges selected.


NOTE: To prevent excessive battery discharge, the heated front seats will only operate when the engine is running.

Heated and Cooled Front Seats

The TSD receives a fused power supply from the RJB. Selections made by the driver using the TSD soft keys are passed from the TSD on the MOST ring to the Information and Entertainment module. The information and entertainment module processes
the information and transmits the request on the medium speed CAN bus to the front seat climate control module. The front seat climate control module is located beneath the RH (right-hand) front seat, on the floor cross member.

The front seat climate control module receives its power supplies from the CJB. Heating and cooling requests are generated using the soft buttons on the TSD. These requests are transmitted to the information and entertainment module over the
MOST ring. The Information and Entertainment module forwards these requests to the front seat climate control module over
the medium speed CAN bus.
The front seat climate control module supplies power to the two climate modules in each seat. The temperature sensor in each
climate module is monitored by the front seat climate control module which uses the temperature information to control the
Peltier cells accordingly and also the blower fans to distribute the heated or cooled air.


NOTE: To prevent excessive battery discharge, the heated and cooled front seats will only operate when the engine is
running.
Electric Driver's Seat Adjustment - Non-Memory Seats

The CJB supplies 3 power supplies to the driver's seat switchpack. The fused supplies provide power for the seat height and squab recline, the seat slide and seat tilt and the lumbar adjustment respectively. The CJB only provides the power to the driver's seat switch pack when the ignition is on (power mode 6).

For the seat movement motors, when the applicable switch is operated, the power is supplied to the applicable side of the
motor and the ground path is completed to operate the motor in the required direction. To move the motor in the opposite
direction the polarity is reversed.

For the lumbar adjustment, when the switch is operated in the inflate position, power is supplied to the pump motor to inflate
the lumbar support. When the switch is operated in the opposite direction, the power energizes a solenoid which in turn opens
a valve to deflate the lumbar support.
Electric Passenger Seat Adjustment ( 8, 10 and 12 way)

The CJB supplies 3 power supplies to the passenger seat switchpack. The fused supplies provide power for the seat height and squab recline, the seat slide and seat tilt and the head restraint and lumbar adjustment respectively. The CJB only provides the power to the passenger seat switch pack when the ignition is on (power mode 6).

For the seat movement and head restraint motors, when the applicable switch is operated, the power is supplied to the
applicable side of the motor and the ground path is completed to operate the motor in the required direction. To move the

7 Windshield washer pump 8 Wiper/Washer switch - RH (right-hand) steering column multifunction switch 9 Instrument cluster 10 CJB (central junction box) 11 BJB (battery junction box)


WINDSHIELD WIPERS System Operation

Operation of the wipers and washers is controlled by the CJB in response to driver inputs from the wiper control switch and signals from the rain/light sensor. The instrument cluster monitors the condition of the wiper/washer control switch and
transmits driver requests to the CJB over the medium speed CAN bus.
The wiper control switch is connected via hardwired connections to the instrument cluster. The instrument cluster outputs on 4
wires a reference voltage to the wash/wipe switch, the auto wiper switch, the wiper switch and the flick wipe switch. All the
switches are connected to the instrument cluster on a common ground. Each switch function is connected to ground via a
resistor or series of resistors and the instrument cluster monitors the ground signal and determines which function has been
selected. The instrument cluster then outputs the appropriate message on the medium speed CAN bus to the CJB which responds to the requested wiper function. The CJB then activates the appropriate function either directly or via relays in the EJB for the wipers and headlamp powerwashers. Speed Dependent Mode

When the wipers are operating, a vehicle speed signal received by the CJB on the high speed CAN bus is used to operate a speed dependent mode. If the wipers are in fast wipe and the vehicle speed decreases to below 2 km/h (1.2 mph), the wipers
will reduce to the normal wipe speed. When the vehicle speed increases to above 8 km/h (5 mph) the fast wiper speed
selection is restored. If slow speed is selected and the vehicle speed drops below 2km/h (1.2 mph), the wipers will operate in
the intermittent mode. When the vehicle speed increases to above 8 km/h (5 mph) the slow wiper speed selection is restored
– this feature is configurable by the dealer using the approved Jaguar diagnostic system.
Wiper Motor

The wiper motor is controlled by the CJB. The CJB is connected to a wiper motor normal/fast relay in the EJB on 2 wires. The CJB is also connected to a wiper run/park relay, also located in the EJB.
Driver requests are received by the CJB which energizes the wiper motor normal/fast relay in the appropriate mode (normal or fast wipe) and also energizes the run/park relay in the run mode by providing a ground for the relay coils. When wiper
operation is deselected by the driver, the CJB monitors a park switch which is integral with the wiper motor. On receipt of a signal from the park switch, the CJB de-energises the run/park relay, removing the power supply through the normal/fast relay, stopping the wipers in the park position on the windshield.

The wiper motor is a DC (direct current) motor which drives a gear wheel via a worm drive attached to the motor spindle. The
motor has 3 sets of brushes with one brush connected to ground. When the normal/fast relay is energized in the normal
position, a power feed is supplied to the brush directly opposite the ground brush and operates the motor at slow speed.
When the relay is energized in the fast position, a power feed is connected to the second motor brush, which is offset from the
ground brush and operates the motor at the fast speed. With power supplied through the offset brush, the current flows
through fewer motor coil windings. This results in a lower resistance to current flow to the ground brush and produces a higher
motor rotational speed.

WINDSHIELD WASHERS

The windshield washers are controlled by the CJB. A driver request for washer operation, via the wiper control switch, is passed to the instrument cluster on the LIN bus. The instrument cluster passes the message to the CJB on the medium speed CAN bus.

The CJB energizes the windshield washer pump during the up stroke of the first 2 wash/wipe cycles. This ensures that wiper fluid is pushed to the sides of the windshield and eliminates the trail of fluid which can occur if the fluid is pushed to the
bottom of the windshield. The wipers will continue for 3 more cycles, followed after a delay of 4 seconds, by a single dry wipe.


NOTE: The dry wipe feature is configurable using an approved Jaguar diagnostic system.

The operation of the washer pump on the wiper up stroke only is configurable using an approved Jaguar diagnostic system.

The washer button can be pressed and held and the wipers will operate continuously for up to 10 seconds. After this period
when the button is released, the wipers will continue for 3 more cycles, followed after a delay, by a single dry wipe. After this
period washing will be inhibited, the wipers will continue for 3 more cycles, followed after a delay, by a single dry wipe.
Reactivating the switch will recommence the wash/wipe cycle.

RESERVOIR LEVEL SWITCH

The level switch is connected directly to the CJB. The switch is operated by a float which closes contacts within the switch when the fluid level falls to below the switch level. When the contacts are closed a ground path is completed from the CJB through the switch. This is sensed by the CJB which issues a message to the instrument cluster which displays a low fluid level warning.

HEADLAMP POWERWASHERS

The headlamp powerwash is activated when the driver requests windshield washer operation. The CJB receives the driver request via a CAN bus message from the instrument cluster. The CJB then checks for an exterior lights active signal and that a low washer fluid level signal is not present.

The CJB outputs a control voltage to a headlamp powerwash pump relay located in the EJB. The relay is energized by the CJB for a pre-determined period to allow the headlamp telescopic washers to operate.

The CJB monitors the driver washer requests and only operates the headlamp powerwash on every fourth request for windshield washer operation, provided that 10 minutes have elapsed since the last headlamp powerwash operation. The
powerwash sequence is reset when the headlamps or the ignition is switched off.


NOTE: If a low fluid reservoir level is present the CJB prohibits headlamp powerwash.
RAIN/LIGHT SENSOR

On receiving a request for automatic windshield wiper operation, the CJB interprets LIN bus messages received from the rain sensor. The rain sensor provides LIN bus messages with values ranging from 0 to 7.
A signal value of 0 is interpreted by the CJB as the windshield is dry. A signal value from 1 to 5 is interpreted by the CJB as a small amount of water hitting the windshield. In this instance, the CJB initiates a slow wipe. A signal value of 7 is interpreted by the CJB as a large amount of water hitting the windshield. In this instance, the CJB initiates a fast wipe. NOTES:


The CJB will only change a fast wipe routine to a slow wipe routine if the rain sensor value is lower than 7.

Roof opening panel System Operation

Operation of the roof opening panel is controlled by the roof opening panel control module, which is integral with the motor.
The control module receives inputs from the CJB, which provides an 'open' or 'close' signal for remote handset operation, and
an 'enable' signal when the vehicle enters power mode 6.

The control module also receives a vehicle speed signal from the ABS module. The vehicle speed signal is used by the control
module to calibrate the anti-trap feature.

If the battery is disconnected, or the power supply is interrupted while the roof opening panel is in a partially open position,
the motor and control module will need to be calibrated to restore full functionality. To recalibrate:
1. Switch ignition on.
2. Press the front of the switch, so the roof opening panel is the tilt position, and then release the switch.
3. Press the front of the switch and hold for thirty seconds.
4. After thirty seconds the roof opening panel will begin to move. Keep the front of the switch pressed until the roof
opening panel has fully opened and then closed.
5. Once the open/close cycle has completed and the roof opening panel has stopped moving, release the switch.
6. The roof opening panel can now be operated as normal.

Drain hoses are connected to the front and rear corners of the roof opening panel frame. The drain hoses are located inside of
the cabin on the 'A' and 'D' post pillars to allow water, which has collected in the frame, to escape. One-way valves fitted to
the end of each drain hose, prevent the ingress of dirt and moisture.

Rear window sunblind

The powered rear window sunblind is operated through a switch in the roof console. Power to the sunblind motor is provided by
a pair of relays located in the CJB when the vehicle enters power mode 4. The sunblind motor is located beneath the rear parcel
shelf and is supplied as a sealed unit with the sunblind mechanism.

If the battery is disconnected or a replacement sunblind is fitted, the motor will require re-calibrating. To re-calibrate the
motor the sunblind should be powered through two-full cycles of movement.



Roof opening panel, motor Component Description

The roof opening panel motor has a worm drive which drives a gear in the cast housing attached to the end of the motor. The
gear has a small pinion gear attached to the outer part of its spindle. The pinion engages with two cables to form a rack and
pinion drive. Rotation of the motor turns the pinion which in turn drives the cables in the required direction.

The two cables are attached either side of the pinion. One end of each cable is attached to the guide; the opposite end of
each cable is held in position on the pinion by a metal insert in the frame. The cables run in channels, in the panel frame to
the guides. As the panel is closed the cables are pushed through channels in the front of the frame. The displaced cable is
guided into a further two channels in the frame, which protect the cable and prevent it from snagging. The cables
manufactured from rigid spring steel can pull as well as push the panel along the guides.

The motor contains a micro-switch and Hall effect sensor. Signals received from these components enable the control module
to calculate the exact position of the roof opening panel. The Hall effect sensor is also responsible for the operation of the
anti-trap function.

If the anti-trap feature is activated while the roof opening panel is closing, the panel is reversed for 200mm or as far as
possible. The Hall effect sensor, located in the motor, monitors the speed of the motor and if the speed decreases below a set
threshold, indicating an obstruction, the power feed to the motor is reversed so the panel goes back. In an emergency the
anti-trap function can be overridden by holding the switch in the closed position.

Roof opening panel, control module

The roof opening panel control module is integrated within the motor. The control module receives inputs from the CJB, which
provides an 'open' or 'close' signal for remote handset operation, and an 'enable' signal when the vehicle enters power mode 6.

The control module also contains the algorithm for the anti-trap system and receives a vehicle speed signal from the ABS
module. The vehicle speed signal is used by the control module to calibrate the anti-trap feature.
