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)
