The table below shows the possible navigation system adaptations to the vehicle. The settings can be changed
with the aid of the handheld tester ("HHT").
Navigation parametersPossible settings
ABS pulse count (pulse count
from wheel speed sensor per
wheel rotation)Factory setting:48 (passenger cars)
Tire sizee.g.:195/50/15
Tire condition Guideline values:
Coding is required only when
tires are changed. Tire wear
occurring while driving is
recognized automatically by the
navigation system.New:Tread depth greater than 5 mm

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.
