Revision 6.5

Design Control module

The system for radio reception consists of

• antenna system for AM/FM

• AM/FM tuner module (AFM)

• antenna amplifier.

The AM/FM tuner module (AFM) has the task of receiving radio signals for the AM and FM

wavebands.

The radio signals received by the antenna are decoded and transmitted to the AM/FM tuner

module (AFM). The signals contain information about (see below):

• alternative frequencies (AF)

• program identification code (PI)

• program channel name (PS)

• traffic program (TP)

• traffic messages (TA)

• extended program information (EON)

• program type (PTY).

AM/FM tuner module (AFM) has a 5-band equalizer integrated in the unit. The equalizer

controls the frequency reproduction from the received radio signals.

The antenna amplifier is supplied with power by the AM/FM tuner module (AFM), via

phantom power supply (coaxial cable), with a nominal 11 ± 0.5 V. If the vehicle is equipped

with RTI (Road Traffic Information) the power supply is via the traffic message channel

module (TMC).

The diagnostic trouble code (DTC) is stored and the system is shut down if the voltage

exceeds 13.5 ± 0.5 V. The voltage is regulated to the battery capacity if the battery voltage

is below 10.5V.

When the ignition is switched off the power consumption of the AM/FM tuner module (AFM)

must not exceed 0.1 mA.

The system can endure temperatures between -40 <C and 85 <C.

The control module checks the input and output signals through an integrated diagnostic

system. The control module communicates with directly connected components, and via

MOST communication.
