Poor Radio Reception - Repair Procedure
AFFECTED VEHICLE RANGE:
XK (X150) VIN: B15632 - B25813
Model Year: 2008 ONLY
CONDITION SUMMARY:
POOR RADIO RECEPTION - AM / FM FREQUENCIES
Situation:
An issue has been identified where there may be poor radio reception on the AM and FM frequencies. There may also be a concern of being able to hear some vehicle generated noises on some frequencies. This could be caused by the 120 ohm coaxial cable weakening the signal strength to the concealed antenna.
Action:
Should a customer express the above concern, follow the Repair Procedure to install a 50 ohm coaxial cable and reconfigure the Audio Front Control Module as outlined in this bulletin.
PARTS
TOOLS:
IDS DVD 111 Patch File / or later and Midtronics PSC-550 Vehicle Power Supply
