Last modified 03-Oct-2012 00:00:00
Symptom 207000 Entertainment Systems
Issue:
A customer may report that the Audio/ Video (AV) button
is permanently greyed out.
Cause:
A greyed out AV button can be caused by a variety of
concerns with the infotainment system and are normally
attributed to a Media Orientated Systems Transport
(MOST) ring break or continuity of connections to the
Audio or Video modules.
Action:
If the Audio Control Module (ACM) or Audio Amplifier
Module (AAM) is considered to be at fault and the power
supplies/ earth paths have correct continuity, the simplest
form of check for a module concern is to disconnect the
power supplies to the module for a period of two minutes,
then reconnect the power supplies. Using the MOST
tester, check to see if light is being emitted from the
output side of the MOST port on the module with the
ignition on. If not the module is likely to be at fault and
Content require replacement. If the light source is present then the
module is functioning correctly.
Following analysis of Audio Control Modules that have
been replaced in warranty a wire bonding issue has been
identified on a small number of units that may have
caused the AV button to be greyed out permanently. This
concern would normally be evident at PDI or early in
vehicle life. Counter measures have been implemented in
the module production process for ACMs from serial
number H10722139/ BVJG904A onwards fitted to the
following VIN range:
XF/X250: S20753 - S32000
XJ/X351: V00001 – V29000
Note: All wiring/ cabling issues should be ruled out before
consideration is given to module replacement as any
modules replaced that are found not to have a fault during
supplier inspection may result in rejection of the warranty
claim. Symptom Driven Diagnostics can be used as a
guide during the diagnostic process in conjunction with
the TOPIx.
