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 on the left-hand side, by the rear wheel arch by the audio module (AUD). On the C70 the Global positioning system module (GPS) is on the right-hand side, by the rear wheel arch.
In C30, the global positioning system module (GPS) is located behind the right B-post.
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 the input and output signals through an integrated diagnostic system. A diagnostic trouble code (DTC) is stored if the control module detects a fault. Any diagnostic trouble codes (DTCs) are stored in the control module memory. The data can be read off using VIDA (Volvo scan tool).
