Control Module
The global positioning system module (GPS) receives satellite signals to determine position.
The global positioning system module (GPS) is an option and is only used together with Volvo on Call and when the vehicle is equipped with Multimedia module (MMM).
The Global positioning system module (GPS) is located under the left-hand seat.
The global positioning system has an antenna. This antenna is a combined antenna for GPS and the carphone.
The control module uses optical serial communication to communicate with other components on the MOST network. This means that all communication with the Global positioning system module (GPS) is via the infotainment control module (ICM).
The control module checks input and output signals via an integrated diagnostic system. A diagnostic trouble code (DTC) is stored if the control module detects an error. Any diagnostic trouble codes (DTCs) are stored in the control module memory.
The information can be read off using the diagnostic tool.
