Symptom 207000 Entertainment Systems
Issue:
This SSM has been released to address the high number
of speaker assemblies returned, many of which are
deemed as “No Fault Found”.
Cause:
Incorrect diagnosis.
Action:
Prior to changing any loudspeaker or Subwoofer
Assembly, please check the following:-

Content

That all speaker fixing screws are secure and
correctly torqued.
The harness assembly is not vibrating against
speaker unit.
The harness assembly is not trapped or impeding
the speaker unit.
Check harness assembly connections are fully
inserted and secure.
Check that all surrounding trim panels are correctly
fixed and not causing any vibration that could be
attributed to the speaker.

Once the speaker unit is removed from vehicle, reconnect the harness and check for reported failure mode,
whilst holding the speaker away from its mounting points,
if it does not show the reported failure mode, then the fault
is not with the speaker and attention should be directed to
the surrounding assemblies.
