Control Module
Remote Digital Audio Receiver (RDAR) has the task of receiving both digital satellite and terrestrial radio signals, process them and transmit them onward on the MOST network.
In C70, the remote digital audio receiver (RDAR) is located on the right side at the rear wheel housing above the global positioning system module (GPS).
The control module has serial optical communication with other components in the MOST network. This means that all communication with Remote Digital Audio Receiver (RDAR) occurs via the Infotainment control module (ICM) or on the initiative of the Infotainment control module (ICM).
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.
Any diagnostic trouble codes are stored in the control module memory. The information can be read out via the data link connector in the vehicle.
