2010 JAGUAR XFR Control module

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.

Diagnosis and Testing

Inspection and Verification Published: 15-Jul-2014

CAUTION: 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.
NOTES:


If a control module or a component is suspect and the vehicle remains under manufacturer warranty, refer to the Warranty
Policy and Procedures manual, or determine if any prior approval programme is in operation, prior to the installation of a new
module/component.


When performing voltage or resistance tests, always use a digital multimeter accurate to three decimal places, and with
an up-to-date 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.
1. Verify the customer concern.

2. Visually inspect for obvious signs of damage, water ingress and system integrity.

3. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to
the next step.
4. If the cause is not visually evident, check for Diagnostic Trouble Codes (DTCs) and refer to the DTC Index.
