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.
