Technical Service Bulletin
Service
1. Confirm that the interference is not caused by loose objects (such as keys, CD covers, pens, sunglasses, etc.)
in the vehicle.
2. Confirm that the interference does not disappear when the trim surrounding the speaker is pushed against the
speaker, nor when the speaker is pushed against its mounting.
3. Remove the speaker from its mounting and listen to the speaker isolated from the vehicle:
• If interference is not heard: check for sources of interference in the cabin fittings. Fix any loose parts, and
apply or replace an underlay, as necessary.
• If interference is heard: check if any aftermarket electrical devices are connected anywhere in the vehicle,
or in a 12V power socket. Disconnect power to the device and check if the interference in the speaker is still
present. If the interference is no longer present, explain to the customer that certain devices can interfere
with the radio tuner.
