ISSUE:

ISSUE:ISSUE: A revised AIR pump which is more heat resistant is now available. The pump can be identified by a Julian date code of 002/*/96 or later. (The * in

the date code indicates the shift during which the pump was assembled which is not relevant to the design of the pump.)

This technical bulletin provides a diagnostic procedure to aid diagnosis when DTC P0411 has been flagged. Replacing the ECM will not solve the complaint of flagging DTC P0411.

CTION:CTION:

In case of a customer complaint on a XJS (4.0L) Range vehicle, within the above VIN range, of MIL illumination, with DTC P0411 flagged, follow the diagnostic flowcha rt located on the last page of this bulletin. The following text provides additional information.

The statements in boxes correspond to boxes in the flow chart. Perform diagnosis with the engine at normal operating temperature to ensure that

the HO2S feedback is operating.

Does AIR pump operate?

The pump can be heard running and a light vibration can be felt. The AIR pump operates for a short period of time following every engine start. It

typically operates for approximately 10-20 seconds at normal operating temperatures, then switches off for approximately 5-10 seconds, and then restarts to allow the system diagnostic check to occur. This check also takes approximately 5-10 seconds. See Illustration 1, sample of PDU trace. This complete cycle takes place each time the engine is started. cc

Illustration 2 shows a PDU trace where there is inadequate air flow from the air pump.

Zone ‘A’ shows the initial operation of the air pump (air flow causes lean reading). Zone ‘B’ shows the pump switched off, prior to the diagnostic test (stopping air

flow causes rich reading). Zone ‘C’ shows the pump operating during the diagnostic test cycle. Zone ‘D’ shows the lambda voltage switching to normal feedback, as there is

insufficient air flow to sustain the voltage at 5v. Zone ‘E’ shows the air pump switched off at the end of the diagnostic cycle. Zone ‘F’ shows the lambda voltage switching under normal lambda operation.

Check outlet port of pump for strong air flow

The air flow from the air pump should be strong enough to almost prevent the palm of the hand from staying pressed against the outlet port of the pump. In situations where DTC P0411 is flagged, the air flow from the pump outlet will be very weak.

Check ports of pump for signs of overheating or excessive build-up of carbon.

This check should be performed when the voltage trace is correct, in case of intermittent operation of the pump. Look for excessive buildup of carbon on the outlet port, and check if the foam filter in the inlet port has melted or is out of position. In such cases, replace the outlet check valve also.

Bulletin Number 17-10 Date of issue 8/97 Page 3 of 5

Follow electrical diagrams in XJS Electrical Guide

If the AIR pump does not operate as described on page 1, refer to Fig. 25 of the XJS Range 1995/6 Electrical Guide.

Is “bleed nipple” hose fitted?

On vehicles from VIN 194775 - 199153, check that the hose between the air pump and check valve is the type incorporating an anti-vacuum bleed nipple, as introduced in production from VIN 199154 (refer to Technical Bulletin 18-47 Amended 4/95.) If not, install the appropriate later-design hose.

MODIFICATION PROCEDURE

1. Open the hood and install fender covers.

2. Disconnect the multiple connectors from the intake air temperature sensor (IATS) and from the mass air flow sensor (MAFS).

3. Disconnect the convoluted hose from the throttle body.

4. Remove the nut that secures the rubber mounting bobbin to the induction elbow; release the air cleaner to MAFS retaining clips and remove the MAFS/ induction elbow assembly to provide further access.

5. Unscrew by ONE turn the throttle stop adjustment screw, so that no air gap exists on either side of the throttle plate. It will be necessary to shorten a standard hexagon wrench (Allen wrench) for access to this screw.

6. Hold the throttle closed and remove the screws that retain the throttle plate to the shaft.

7. Note the direction of assembly to assist during reassembly and then remove the throttle plate after opening the throttle shaft.

Note: Note:

Note: During the above operation, ensure that the shaft is not

Note: Note: pulled out of the potentiometer. If this occurs, removal of the potentiometer will be required to permit reassembly.

8. Gently return the shaft to the ‘closed’ position.

9. Use a suitable solvent and shop towel to carefully remove all residual

Bulletin Number 17-11 Date of issue 12/98 Page 1 of 5

contaminants from the throttle plate and throttle body air passage. Use care not to allow excess solvent to run down the throttle shaft or enter the intake manifold. Use a mirror to assist in checking that all deposits have been removed. Dry off any residual solvent/deposits.

10. Using care not to disengage the throttle shaft from the potentiometer below, and noting the correct orientation, reinstall the throttle plate in the shaft. Apply thread locking compound to the threads of the securing screws and start, but do not fully tighten, the two securing screws.

11. Check with a mirror that the throttle plate is centered with the throttle fully closed, as the retaining screws are tightened enough to grip the plate. Open the throttle against spring pressure, then allow it to snap closed - this will help center the throttle plate on the shaft and to the venturi. Repeat if necessary, then fully tighten the throttle plate retaining screws.

Caution:Caution:

Caution: No specific torque setting is available for the throttle

Caution:Caution: plate screws. Tighten them appropriately for brass screws of this size.

12. Check that the locking patch of the throttle stop screw is still effective. Sufficient drag must remain to ensure that any setting will not be disturbed by vibration, otherwise apply fresh locking compound. Adjust the screw to open the throttle plate until a narrow 0.002 inch feeler blade can fit between the throttle plate and the venturi.

13. Remove the screws that retain the fuel rail cover and remove the cover.

14. Loosen the clamps and remove the breather hose from the engine.

ISSUE:ISSUE:

ISSUE:

ISSUE:ISSUE: Since the introduction of the AJ16 engine Jaguar has seen a high rate of

replacement of EGR valves following illumination of the malfunction indicator lamp (MIL). This is understood to be a result of accumulated contamination within the EGR valve that can produce possible drivability issues such as rough idle, hesitation, and difficult starting.

Following consultation with the US En vironmental Protection Agency (EPA) Jaguar has decided to recall all vehicles equipped with this engine and carry out a number of modifications including the introduction of a cleaning cycle to the EGR valve. The following actions apply to all vehicles within the above VIN ranges.

• Replace PROMs within Engine Control Module (ECM). J aguar Cars has upgraded the PROMs within the ECM to provide a cleaning cycle of the EGR system.

Bulletin Number 17-12 Amended 08/02 Date of issue 11/0 1 Page 1 of 16

• Replace EGR valve and gasket, to ensure that it is free from contamination.

• Replace throttle return spring. Some vehicles may experience customer complaints of high idle speeds.

Jaguar Cars is writing to all owners of the above vehicles (in timed mailings) to advise them to take their vehicles into their local dealer to have the above modifications made.

This recall will supersede Service Action S483, S675, and S676, no further claims for these Service Actions will be accepted.

FALSE ALARMS The cause of the last 8 vehicle

alarms may be checked by using the PDU to interrogate the Security Locking Control Module (SLCM). The causes of the alarms are stored in the Last Alarm Data section of the Security Diagnostic PDU software. See flowchart on page 6.

It is possible for False Alarms to be generated along with the following symptoms:

1. Symptoms:

• Transmitter will intermittently not lock the vehicle and/or the door locks “cycle” and/or the security system emits error tones.

• Vehicle will not start and alarm is inoperative.

• Alarm self-activates.

• When “Drive” is selected, all doors do not lock automatically.

VIN Range affected: 720001 - 735432

Possible cause:

Moisture contamination in one or both right and left door multiplugs RD3. Experience has shown that the multiplug on the right rear door is more prone to this problem and should be checked first. If the connector is corroded, both the door lock module harness and the door harness should be replaced.

2. Symptom

• Intermittent error tone whenever the transmitter button is pressed and/or the system will not arm.

VIN Range affected: 720001-ON

Possible cause:

Faulty ignition switch in steering lock.

Date of issue 10/95 Bulletin Number 18-10 Page 3 of 7

3. Symptom

SECURITY SYSTEM NOT ARMING

1. If arming of the security system is inhibited when using either the key or the transmitter, check that the following inputs to the SLCM are not active:

• Trunk lock intermittently does not release from either the

(Wire color codes: U=Blue, R=Red, W=White, N=Brown, O=Orange) If any of the circuits are suspect, also check for entry of moisture into the

rear door multiplug RD3.

TRANSMITTER TOTALLY INOPERATIVE If the transmitter is totally inoperative, check whether the

LEDs on the transmitter illuminate when the “Lock” or “Unlock” button is pressed.

If the LEDs do NOT illuminate, check the transmitter battery voltage levels. Each battery should be approximately 3 volts.

If the LEDs DO illuminate, check that the transmitter and security system have not lost their code synchronization.

The system is designed with a rolling code window of 100 activations of the transmitter. This means that if the transmitter is operated 100 times out of range of the vehicle to which it is coded, it will lose synchronization with the vehicle. If this occurs, repeated operations of

the transmitter will not unlock the vehicle. In this case, the security system may be disarmed by

unlocking the doors using the vehicle key. Once the vehicle is in an unlocked and disarmed state,

the RF transmitter(s) will re-synchronize to the vehicle after 3 activations within signal range.

NOTE:NOTE:

NOTE: If the transmitter and the SLCM

NOTE:NOTE: have lost code synchronization, and the transmitter button is pressed while the vehicle is locked and armed, the SLCM may enter the “Anti-scan” mode. This will inhibit any transmitter operation for approximately 2 minutes.

Date of issue 10/95 Bulletin Number 18-10 Page 5 of 7

POOR TRANSMITTER RANGE If the transmitter operates, but the

range is poor, first check the range of the second transmitter. If both transmitters have equally poor range, check the following before replacing any items.

1. Check the voltage of the transmitters’ batteries. Each battery should measure approximately 3 volts.

2. Check the integrity of the harness for the following inputs to the SLCM:

Function Connector Identification RF Ground SLCM Connector CA 20-7 (BRD) RF Antenna Signal SLCM Connector CA 20-15 (WN)

(WIre color code: W=White, N=Brown, BRD=Shielded cable)

SLCM DOES NOT ENTER THE MANUAL LEARN MODE

If the SLCM will not enter the “Learn mode”, check the following:

• The ignition key must be in the “Ignition On” position.

• The security system must be disarmed.

• All the vehicle doors must be unlocked.

• The vehicle must not be in the “Valet” mode. (Open the trunk lid before attempting to enter the “Learn” mode.)

If the points at the left have been checked and the SLCM still will not enter the “Learn” mode, check the integrity of the following inputs to the SLCM.

ISSUE:ISSUE:

ISSUE:

ISSUE:ISSUE: Some long wheelbase (LWB) Sedan Range vehicles within the above VIN range

were equipped with 315 MHz Security and Locking Control Modules (SLCM) and key fob transmitters in spite of having rear glass antennas intended for 433 MHz systems. However, this condition has not been found to have a significant effect on the performance of the security system.

While the SLCM and rear glass antenna do not need to match, the key fob transmitters and the SLCM must be the same frequency. A key fob transmitter of one frequency will not function with an SLCM of the other frequency.

Long wheelbase vehicles beginning with VIN 758729 are equipped with a complete 433 MHz system. Short wheelbase vehicles were changed to the 433 MHz system starting with VIN 759614. The 433 MHz was introduced to give improved reliability and more consistent performance.

The frequency is incorporated in the last 3 digits of the FCC ID number. This number is located on the back of the key fob transmitter battery cover and on the sticker on the SLCM. The antenna is located near the top center of the rear glass and can be identified by its configuration (Illustration 1).

Recognize V12 6.0L DTC 67

MODEL

ISSUE: If DTC 67 (Air injection operation) is flagged on the Vehicle Condition Monitor, PDU will not

recognize or erase the code. ACTION:

If DTC 67 is indicated on the VCM of XJS V12 or XJ12 vehicles, check for normal operation of the Secondary Air Injection System (AIR).

Secondary Air Injection System Check: Start engine.

NOTE: At engine start-up with coolant temperature below 1170 F (470 C), the Sec-

ondary Air Injection Pump (AIRP) operates continuously until the coolant temperature reaches 1170 F (470 C).

• Coolant temperature above 1170 F (470 C). At engine start-up with coolant temperature above 1170 F (470 C), the AIRP operates for a programmed period of time depending on coolant temperature. The AIRP then operates a second time for OBD monitoring.

DATE

7/94

18-42

NOTE: If engine speed exceeds 900 RPM during the OBD monitoring phase, the

AIRP switches off. When the engine returns to normal idle speed OBD monitoring will repeat and the AIRP will operate.

If Oxygen Sensor Feedback (HO2 SFB) indicates excess oxygen (lean) in the exhaust while the AIRP is running the second time (OBD monitoring), the OBD test is passed. If Oxygen Sensor Feedback (HO2 SFB) does not indicate excess oxygen (lean) while the AIRP is running the second time (OBD monitoring), the CHECK ENGINE light turns on and DTC 67 is flagged.

Refer to Service Manual section 17.3 for DTC 67 diagnosis information.

To erase the DTC from ECM memory:

• Switch ignition OFF.

Remove and destroy Bulletin 18-47, Date 3/95. Replace with this Bulletin. Revisions are marked with a bar and indicated in Bold Text.

ISSUE: The CHECK ENGINE MIL illuminates with no loss of power on 1995 MY vehicles within the

VIN ranges listed below. Diagnosis with PDU indicates that DTC P0411 is stored in memory.

Sedan (4.0L) Range VIN 720001- 734672 XJS (4.0L) Range VIN 194774 - 199153

At the end of the secondary air injection cycle, vacuum may become trapped in the hose from the air pump (AIRP) to the secondary air injection check valve (AIRC). The trapped vacuum will not allow the AIRP solenoid operated stop valve (integral with the AIRP) to open during the next air injection cycle. The ECM monitors no drift in the HO2S swing s, which triggers the CHECK ENGINE MIL.

A revised air pump hose with a vacuum bleed is fitted to all AJ16 engines in production from VIN 734673 (Sedan [4.0L] Range) and VIN 199154 (XJS [4.0L] Range).

18-53

Diagnostic Procedure

MODEL 1995-96 XJS (4.0L) Range

ISSUE:ISSUE:

ISSUE:

ISSUE:ISSUE: The adaptive fuelling system operates within predefined adaption limits to

maintain an optimum performance level. Both the Fuel Mass Flow Rate (FMFR) and the Air Mass Flow Rate (AMFR) are monitored by the ECM to ensure they stay within the adaption limits. However, if a fuelling system problem occurs and the adaption limits are exceeded, a Diagnostic Trouble Code (DTC) is then stored in the ECM. The engine Malfunction Indicator Lamp (MIL) will illuminate to report the presence of the DTC. The MIL will stay illuminated until the DTC has been cleared using the PDU.

The flow cha rts which accompany this bulletin are provided to assist in diagnosing the above DTCs. Each DTC is represented by an individual flow chart which is used in conjunction with PDU.

CTION:CTION:

CTION:

CTION:CTION:

NoteNote

Note: It is unlikely that replacing the mass air flow sensor (MAFS)

NoteNote will rectify the above DTC problems.

DATE 11/97

If one or more of the above DTCs are stored in the ECM, then the PDU should be used to identify and clear the DTC(s). After identifying the DTC(s) use the appropriate diagnostic flow cha rt to diagnose the fault.

After repairing a fault described in the flow chart, complete the next flow chart instruction to ‘Reset and Check AMFR adaption’ or ‘Reset and Check FMFR adaption’ to determine if the fault has or has not been successfully repaired. It is not necessary to check or reset adaptions if no faults are identified. Resetting and checking the AMFR and FMFR adaptions is achieved by following the procedure on page 6.

PROCEDURE TO CHECK AND RESET ADAPTIONS

• Run engine at normal operating temperature.

• Load disc PDU 1055 into the PDU at the base station. (PDU Disc 1055 has the capability of reading the long term fuelling trim

adaptions. This facility will confirm whether AMFR and / or FMFR are running at mixture that is too lean or too rich. These values are found in the PDU datalogger facility.)

• Select DIAGNOSTICS from the main menu.

• Enter VEHICLE DETAILS.

• Select TOOLBO X from the DIAGNOS TICS MAIN MENU.

• Select POWERTRAIN from the TOOLBOX MAIN MENU screen. The information screen will request that the PDU is connected to the vehicle.

• Select DATALOGGER from the PDU tools function.

• In DATALOGGER clear the default parameters and then select ‘AMFR’, ‘FMFR’, ‘CLV’ (Calculated engine Load Value), and RPM (Illustration 1).

• Select bar chart form, this will enable viewing of the adaption values, and act as an accurate monitor of the RPM.

• Note and record the AMFR adaption and FMFR adaption displayed values.

• Return to the PDU base station and load RESET ADAPTIVE VALUES from the TOOLBOX menu screen.

• Connect the PDU to the vehicle and reset the adaptive values.

• Return to the PDU base station and reload DATALOGGER from the PO WERTRAIN option of the toolbox menu screen.

• Continue with the procedure in ‘Drive Cycle’ on the next page.

DRIVE CYCLE To enable the AMFR adaption and/or FMFR adaption to reset, the following

preconditions must first be obtained:

• Air intake temperature must be between, 10 deg C and 55 deg C.

• Engine coolant temperature must be between, 80 deg C and 100 deg C. Illustration 1 shows a view of the PDU screen in bar chart form with the relevant

conditions and typical values for an engine in good fuelling order.

Note:Note:

Note: Where values are less than 1 kg/hr, the PDU display will

Note:Note: show the values as g/hr, for example, 500 g/hr rather than 0.5 Kg/ hr. (Illustration 1).

Drive the vehicle at a steady speed, between the RPM and the engine load values for the model year stated below, until the FMFR adaption value changes and then stabilizes. Obtain the correct engine load and RPM balance by driving on a highway with 3rd gear (manual) selected at the stated RPM, while applying slight pressure to the foot-brake to maintain engine load.

arningarning

arning: For safety reasons the FMFR adaption process

arningarning must be performed by two persons: Driver, and Passenger - to monitor the PDU and advise the driver of when the engine is being driven between the RPM and engine load values stated below.

1995 MY: engine speed 1500 to 3000 RPM; engine load 27.3% to 40%. 1996 MY: engine speed 2000 to 3000 RPM; engine load 23.4% to 40%.

When performing the FMFR adaption drive cycle, the stated RPM and engine load values must be adhered to, otherwise the adaption will stabilize at the incorrect value.

When the FMFR adaption value has changed and stabilized, and the adaption is within the above stated adaption values, then the previous flow chart repair has been successful. If the adaption is still outside of these values then continue to follow the flow chart until the fault is found.

After the completion of each flow chart repair , dump the trace snapshot into the trace buffer, which can then be printed out and be used for Warranty Audit Purposes.

CAUSE OF CORONA DISCHARGE While an engine is running, Corona discharge can sometimes be visible as a pale

blue light around the high-tension secondary boot and the spark plug’s insulator surface. This discharge is due to ionization that occurs when gas molecules separate into free electrons and positively charged ions. If the air is highly ionized, the insulation ability is reduced and partial discharge occurs, resulting in the pale blue light.

Corona discharge occurs on rainy days or when the insulator surface is dirty. Due to ribbed corrugations at the top portion of the spark plug, corona is prevented from reaching the top of the spark plug which could cause the engine to misfire.

Rough Idle/Drivability – Diagnosis to

Follow Prior To Replacing MAF

18-56

MODEL 1995-96 XJS (4.0L) Range

ISSUE:ISSUE:

ISSUE:

ISSUE:ISSUE: Some 1995-96 MY XJS (4.0L) Range vehicles may experience concerns of poor

idle quality, hesitation and other drivability concerns. The Mass Air Flow Sensor (MAFS) is sometimes replaced in an attempt to repair this concern. However, the MAFS have been tested and found to be fault free. As a result, this Technical Bulletin has been issued to offer alternatives to replacing the MAFS.

GENERAL INFORMATION The AJ16 engine has been tuned for maximum power with the best possible fuel

consumption to meet the stringent emission regulations for the North American market. Due to individual driving patterns, along with the engine design characteristics, the occasional idle dip can occur. This is considered normal. However, should a customer complain of poor idle quality (and in comparison to other vehicles seems to be worse) or any other drivability concerns, the following information should be followed rather than replacing the MAFS.

Note:Note:

Note: On early 1995 MY vehicles with low mileage, MAFS were

Note:Note: replaced due a known build issue by the supplier. This issue was limited to a specific build range of parts and was corrected on all components produced after that date range. Therefore, this is no longer an issue as a potential root cause.

DATE 02/01

CTION:CTION:

CTION:

CTION:CTION:

In case of a customer complaint of poor idle quality on a 1995-96 MY XJS (4.0L) Range vehicle, check the following alternatives to replacing the MAFS:

1. Using the Portable Diagnostic Unit (PDU) or World Diagnostic System (WDS), check for relevant Diagnostic Trouble codes in the Engine Control Module (ECM). If DTCs P0101, P0102 and P0103 are stored and diagnosis confirms a faulty MAFS,

2. Identify and ensure that the correct fuel injectors are installed:

4. Check the camshaft timing changes (refer to TSB 12-57).

5. Check that the EGR valve is operating correctly (refer to TSB 17-12).

Note: Note:

Note: The EGR valve will only need replacing if the relevant DTCs

Note: Note: are stored in the ECM memory.

Should any of the above not rectify any case of poor idle quality, the Mechanical Fault Diagnosis information in section 3 of the AJ16 Service Manual should be followed. On JTIS, select 1995 XJ6/XJ12, under General Information, select 101-02 Diagnosis & Testing, section 3.2 Diagnostic Procedures.

For poor idle quality and other drivability concerns, using the PDU or WDS, check the long-term and short-term fuel trims. If any are found to be high, check for air (vacuum) leaks and for the general fuel pressure being too high. The PDU or WDS can be used to re-set the ECM adaptions (refer to TSB 18-53) after rectification work has been carried out.

Note:Note:

Note: If a customer complains of any other drivability concerns,

Note:Note: check that the throttle body and butterfly are clean from carbon deposits and that the engine breather modification has been carried out (refer to TSB 17-11).

If the problem persists, contact the Technical Hotline for further information with a list of any rectification work that has already taken place.

• 1994 to 1995 Model Year XJS V12 Vehicles VIN Range: 188105-221234

• 1994 Model Year XJ12 Vehicles VIN Range: 673590-708235

In addition, the following 1994 Model Year pre-production XJ12 vehicles should be modified: 671007, 671040, 671110, 671139, 671177, 671224, 672305 and 672308 (USA) and 671078 for Canada.

Some XJS 6.0L V12 and XJ12 series vehicles within the above VIN ranges may experience customer concerns of the ‘check engine’ malfunction indicator light illuminating with diagnostic trouble codes (DTCs) FF44 and/or FF45 stored. These DTCs show an inconsistent reading from the Heated Oxygen Sensors (HO2S). The HO2S are giving a faulty reading due to a slight degradation of the engine to body ground straps.

In order to prevent this issue occurring again, two supplementary ground straps need to be added to all vehicles within the above VIN range.
