The following diagnosis might be helpful if the vehicle exhibits the
described symptoms in the PI.</P><A name=ss1-1533249><A

<H5>Condition/Concern:</A></H5>
Owners may notice that after the ignition key is cycled the "Auto Volume"
feature is inoperative even though, the feature is still on. The radio stores
the memory for the Auto Volume. At start up, the radio sends a class 2 message
to amplifier to turn on "Auto Volume". Due to a software concern the amplifier
does not receive the class 2 message from the radio, in turn the "Auto Volume"
feature is disabled. If the "Auto Volume" button is cycled off and then back on,
the radio will resend the class 2 message to the amplifier, and the "Auto
Volume" feature will turn on. </P><A name=ss2-1533249><A

<H5>Recommendation/Instructions:</A></H5>
At this time there is no repair for this concern. If the owner would like the
feature on they will have to cycle the "Auto Volume" button off and on after
each ignition cycle. </P>

Please follow this diagnosis process thoroughly and complete each step. If
the condition exhibited is resolved without completing every step, the remaining
steps do not need to be performed. If these steps do not resolve the condition,
please contact GM TAC for further diagnostic assistance.</P><A
