RDS reception (Radio Data System) is possible with FM broadcasts (market-dependent). The system is called RBDS (Radio Broadcast Data System) in
USA.
The front and rear door speakers are connected to the control module or to the external amplifier's audio module (AUD), if fitted (regards High
Performance and Premium Sound).
For more information on the speakers for High Performance and Premium Sound, see Design and Function, Audio Module (AUD).
The integrated audio module (IAM) checks executed activations and input/output signals via its integrated diagnostics. If the control module detects a
fault, a diagnostic trouble code is generated. Any diagnostic trouble codes are stored in the control module memory. The information can be read via the
data link connector in the vehicle.
