AUDIO 30 APS DIAGNOSIS, BASIC KNOWLEDGE - AD82.61-P-2001A
MODEL 163,168,170, 208, 210 with CODE (353) Audio 30 APS
Used:Tread depth less than 5 mm

In order to avoid damage
to control modules,
connectors must only be
disconnected or
connected with "terminal
15R:OFF "

Local or atmospheric
influences can cause
disruption to radio or
satellite reception.
Satellite reception is
possible only in the open
air.
Position finding with
assistance of global
positioning system data
(in degrees of longitude
and latitude) takes place
within a period of 1 to
20min after "ignition: ON
".
The audio 30 APS is a
navigation system with
integrated radio and CD
player and . It also
provides an interface for
external audio
components via a digital
data bus (D2B). Existing
DMNL deals mainly with
navigation system.
Diagnosis of the
following systems: radio,
D2B, loudspeaker
system (LS), CD
changer and sound
system can be extracted
from the appropriate
DMNL.
