Issue:

A concern has been identified with the operation of the throttle on a number of 1997-98
MY XK8, 1998 MY XJ8 and 1998-99 MY XJR and VDP SC vehicles. Under exceptional
circumstances this concern could cause the engine to cut out, although the engine will
continue to be driven by the road wheels through the transmission and drive the
ancillaries, so there will be no loss of power steering, brakes, air conditioning, etc. The
engine should restart without difficulty once the vehicle has come to a complete
standstill.

later.

NOTE: THE INFORMATION IN TECHNICAL BULLETINS IS INTENDED FOR USE BY TRAINED, PROFESSIONAL TECHNI­CIANS WITH THE KNOWLEDGE, TOOLS, AND EQUIPMENT TO DO THE JOB PROPERLY AND SAFELY. IT INFORMS
THESE TECHNICIANS OF CONDITIONS THAT MAY OCCUR ON SOME VEHICLES, OR PROVIDES INFORMATION THAT
COULD ASSIST IN PROPER VEHICLE SERVICE. THE PROCEDURES SHOULD NOT BE PERFORMED BY “DO-IT­YOURSELFERS.” DO NOT ASSUME THAT A CONDITION DESCRIBED AFFECTS YOUR CAR. CONTACT A JAGUAR
RETAILER TO DETERMINE WHETHER THE BULLETIN APPLIES TO YOUR VEHICLE.

RE-PROGRAM ENGINE CONTROL MODULE (ECM)
1997-98 XK 001036 to 020734
1998 V8 XJ (both NA and SC) 812256 to 819771

Note: Before continuing, ensure the following:

• The PTU is docked on the base station.

• The WDS base station is connected to the line power supply.

• The vehicle battery is in a good state of charge (12.5 volts).

• All Diagnostic Trouble Codes (DTCs) are cleared.

The engine coolant and intake air temperatures MUST be below
50° C (122° F) for the following operation.

Caution: Do not attempt to ‘trick’ the system by cooling the

ECT sensor or sustituting a different ECT sensor. The EPROM
within the ECM is temperature sensitive and must be cool for
programing to take place correctly. Failure to follow the
guidelines may result in the ECM becoming inoperative, which
will result in non-payment of the warranty claim.

Component Locations

During the reflash procedure, the WDS will prompt the technician to temporarily remove
relays and fuses. Since some fuses can be confused with similar ones in other

locations, refer to the chart below before beginning the reflash procedure.

RE: S-514 Service Action – Closed Throttle Operation

Dear Jaguar Owner:

Jaguar Cars has identified a concern relating to the operation of the throttle body while in
the closed position that may exist on the specific models listed below. If you are a recipient
of this notice, and an owner of one of the vehicles within the VIN range, this letter is to inform you that
your vehicle is included in this service action.

The following is a breakdown of the affected vehicles by model year, model and (VIN) range.

➢ 1997-1998 XK Vehicles 001036-031302
➢ 1998 XJ Vehicles Normally Aspirated Engine 812256-853935
➢ 1998-1999 XJ vehicles Supercharged Engine 812256-878717

What is the problem?

A concern has been identified with the throttle operation while in the closed position on a number of
vehicles that could include your vehicle. Under exceptional circumstances this concern could cause the
engine to cut out. If this occurs, the engine will continue to be driven by the road wheels through the
transmission and there will be no loss of power steering, brakes, air conditioning, etc. The engine should
restart without difficulty once the vehicle has come to a complete standstill.

This concern can be rectified by a modification to the throttle operation of your vehicle. Although it is
most unlikely that you will have experienced this issue with the functionality of the throttle in your vehicle,
Jaguar has determined that the engine management software that controls the throttle strategy does not
meet our expected durability requirements.

What will Jaguar and your Dealer do?

Your vehicle will be repaired to modify the throttle operation at no charge to you.

What should you do?

At your earliest convenience you should contact your authorized Jaguar Dealer who will be able to make
an appointment to undertake the necessary actions. To assist your Dealer please ensure that at the time
of contact you have at hand your applicable Vehicle Identification Number.

The time to complete the repair on your vehicle is approximately one hour. However due to vehicle
scheduling and the temperature of the engine, your Dealer may need to keep your vehicle longer to
complete the repair.
