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.
