Standard sound system diagnosis
The diagnosis process is effected via address
word 47 as in the case of the series equipment,
however, the separate control unit for digital sound
system, J525, is now addressed. In addition to
reading the measured-value blocks and the fault
memory for all loudspeaker channels involved,
selective actuator tests are also available.
The digital sound system control unit participates in
component protection.

Mobile baseplate diagnosis
The mobile baseplate is diagnosed as standard
using the address word 77 in the VAS tester.
A selective or sequential actuator test can be
performed to check the output of the audio signal to
the relevant sound system, radio mute operation,
and whether or not a switched-on phone was
detected.
