Poor AM or FM Reception - Diagnostic Procedures - Modification Procedure

Issue:

Some owners of 2000-02 MY S-TYPE vehicles may complain of poor radio reception on both AM and FM.

This Technical Bulletin is designed to provide a quick check for specific AM/FM reception interference issues.

With all diagnostic checks carried out and with a 'No Fault Found' (NFF) situation, a roof-mount manual aerial service fix option may be offered to

reduce multipath (interference caused by signals rebounding back of buildings) and improve reception.

Action:

On a customer complaint basis only, follow the workshop procedure outlined in this Technical Bulletin.

S-TYPE - AM/FM AUDIO INTERFERENCE DIAGNOSTIC CHECKS

VIN L00267 TO L77674

Check the history of vehicle to ascertain whether actions described in Technical Bulletin S415-01 (AM reception interference) concerns have been

carried out on vehicles between VIN L00267 to L77674. If not do this first.

If there is no AM, check that the red/yellow wire is present between FC40-4 and FC71-7. Check all coaxial cable connections, check the FUBA

connections and make sure the mounting is good since it is also a ground. Check the harness between the FUBA and the rear glass for opens or short

circuits. Check the rear glass terminal, check that the black/white wire is to the top and check the rear glass for shorting between the pins.

AM/FM RECEPTION ISSUES VIN L77675 TO M44997

AM-Specific issue

Concern - Standard Corporate Protocol (SCP) network interference, evident with the ignition in auxiliary position I, and engine run position II.

Noise does not increase with engine RPM. The noise exhibits itself as a ticking and is primarily due to inadequate screening of the antenna circuitry.

At VIN M20244 the antenna module to screen harness was screened. Between VIN L77675 to M20244, if this concern is identified, check the

antenna lead to see if it has already been replaced with the latest screened condition. To check, carry out the following workshop procedure.

1. Remove the left hand side rear quarter trim panel to expose the Antenna Module. (See Workshop Manual, JTIS CD ROM, section: 501-05)

2000 Jaguar S-Type (X200) V6-3.0L Page 118

2. Carefully unclip the antenna harness (As indicated at 1 Illustration 1) from the screen connections and disconnect from the antenna module.

(As indicated at 2 Illustration 1)

3. Carefully pull back the harness insulation tape at the connector and check to see if there is a braided cable situated between the two harness

cables. If not fitted, install new modified cable, part number: XR8 36434 (Illustration 2).

Note:

When refitting the screened lead to the terminal, the black wire with white tracer should be connected to the upper screen terminal.

Should the concern persist with a screened harness fitted check the antenna module ground circuit.

4. Check if fixing bolt securing the antenna module bracket to the D-post is tight. If loose tighten to 6.2 Nm.

5. Disconnect antenna module coax connector from the module. (Using a suitable multimeter with appropriate ohm setting). Connect one probe

to ground point on the antenna module and the other probe to the local ground point on the rear bulkhead behind the seat squab trim. (As

indicated at 3 Illustration 3)

Note:

Do not connect the multimeter probe to the fixing bolt for antenna module.

6. If a high resistance reading is present a concern with the antenna module ground connection exists. The ground path for this is through a

dedicated cage nut on the rear bulkhead. Loosen the fixing bolt to the cage nut and re-torque to 6.2 Nm. to re-establish the correct ground

path.

NO AM RECEPTION BUT POSSIBLY SOME FM STATION COVERAGE

Assuming the radio unit is powering up and operating correctly, the fault could be caused by the loss of 12-volt supply to the antenna module.

1. Using a suitable multimeter, check voltage at electrical connection CA2O at the antenna module, if there is no voltage, check voltage at the

intermediate electrical connection FC4O pin 4. This electrical connector is located at the left hand side of the facia assembly behind the A-post

cover. If there is voltage at FC4O pin 4 electrical connection then the fault is within the rearward electrical harness section to the antenna

module.

2. Check all electrical terminals and wires are secure and connected correctly. If satisfactory the fault is within the electrical harness.

2000 Jaguar S-Type (X200) V6-3.0L Page 119

3. If there is no voltage present at FC4O pin 4 remove radio and check voltage output from electrical connector FC71 pin 7 (on some wiring

diagrams this connector is FC73 pin 7). If there is no voltage at FC71 pin 7 check battery/ignition inputs and fuses.

Circuitry details as shown.

AM/FM Combined Issues

Concern-Overall poor radio reception, increased multipath issues on FM broadcasts.

1. Remove left hand side C-pillar trim to expose antenna module. (See Workshop Manual, JTIS CD ROM, section: 501-05, SRO 76.13.73).

2. Carefully unclip the antenna harness from the screen connections.

3. Using a suitable multimeter with appropriate ohm setting selected, place one probe on the upper screen stud and the other probe on the lower

stud. The expected reading should be '0' ohms. If there is a high resistance reading then check for solder splash between the two screen studs

or screen sealant on the studs. If contamination is present this should be carefully removed with a suitable blade or implement.

4. If there is interference only when the Heated Rear Window (HRW) is switched on, affecting AM frequencies and weaker FM bands, possibly

caused a break in the circuit of the HRW. Install new screen.

FM Issues

Concern-Poor radio reception all frequencies.

1. Remove left hand side C-pillar trim to expose antenna module. (See Workshop Manual, JTIS CD ROM, section: 501-05, SRO 76.13.73).

2. Carefully unclip the antenna harness from the screen connections.

3. Using a suitable multimeter with appropriate ohm setting selected, place one probe on upper screen stud and second probe onto heated rear

window buzz bar, the reading should be 6 ohm plus or minus 1 ohm. If the reading is higher than 6 ohm this will indicate that there is a break

somewhere in the screen element circuitry.

Install new screen.

Note:

If the screen is damaged it is not covered under warranty.

General Information

Concern-AM/FM poor radio reception.

If the customer has a non-Jaguar phone, and glass whip aerial installed on the rear screen. The location of the aerial, if in contact or close to

the rear screen elements could compromise radio reception signals. Even if the glass whip aerial is disconnected, the actual presence of the

aerial on the screen could be a factor.

Note:

2000 Jaguar S-Type (X200) V6-3.0L Page 120

If any of the diagnostic checks require repair, carry out a separate warranty claim. This Technical Bulletin only covers the interference

diagnostic checks and the installation of the roof mounted manual aerial.
