Programming and Relearning

Downloading software and replacing the control module

Software can be downloaded to the global positioning system module (GPS). When software is ordered, the vehicle' software and hardware is compared to Volvo's central database. If they are compatible, the software is downloaded to the system.
If the comparison between the car and Volvo's central database does not correspond, then the database is updated with the vehicle's configuration. When this is complete the software is downloaded.
After replacing the control module the module's unique ID number must be programmed in the Central electronic module (CEM). For more information regarding this, see Design and Function, MOST network.
