Jaguar XJ (X350). Manual — part 1362

fuel pump circuit should be verified. A fuel pump module, which is controlled by the ECM supplies

the fuel pump. In all cases of suspected PATS non-start issues, the most logical failure modes should

be eliminated first. Check all relevant supplies and grounds to the IC and ECM, check that the starter

relay has a permanent 12v supply, check that the relay has a 12v supply and ground across the coil

whilst the ignition is in the crank position.

PATS Fault Codes

For the various PATS modes/faults listed in the table , the IC will store a DTC and indicate this to the

customer during the detection peroid 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 is turned to off any time during the fault indication

sequence. Up to 4 DTC's could be stored per key read (1-!0 read attempts). No DTC's will be stored

until all retry attempts are complete. Only the highest priority fault code will be flashed.

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 run 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 run/start event. PATS faults will be indicated

via the LED as soon as possible and will terminate the LED prove out. At key off all previous flashing

will cease and the perimeter anti theft system will control the LED when the vehicle is locked and

armed.

1 . If an obvious cause for an observed or reported concern is found, correct the cause (if possible)

before proceeding to the next step.

2 . If the cause is not visually evident, verify the symptom and refer to the Jaguar Approved

General procedures

Universal Transmitter Programming

WARNING: A garage door opening system that cannot stop or reverse itself after

detecting an object in its path does not meet current federal safety standards. To
decrease the risk of serious injury or death, do not use this HomeLink transmitter with
a door opening system that lacks stop and reverse features as required by federal
standards. This includes any garage door opening system manufactured before April 1,
1982. For more information, call HomeLink customer assistance at 1-800-355-3515.

1.

CAUTION: During this procedure, the system that you are programming will be

made to operate. Make sure that people or objects are clear of the garage door or gate
being programmed.

Verify the hand-held transmitter is operative.


2. Prepare for programming the universal transmitter by erasing all three channels by holding
down the two outside buttons until the red light begins to flash (20-30 seconds). Release both
buttons.

3. Select one of the three universal transmitter channels to be programmed by pressing the
desired button.


4. Hold the end of the hand-held transmitter 50-150mm (2-6 in) from the front surface of the
universal transmitter so that the red light can still be seen.
