Diagnosis sound amplifier
The sound amplifier (A2/13) makes available the following messages relevant to diagnosis:
^
Operating status
^
Undervoltage
^
Internal fault in the sound amplifier (A2/13)
The messages are transmitted to the COMAND operating, display and control unit (A40/3) or the radio (A2) via the D2B and can be read out via the
diagnosis line.
In order to test the D2B system when installing and to localize any fault sources or in order to be able to reproduce faults which have occurred during
operation, a diagnosis mode has been implemented in the sound amplifier (A2/13).
