Downloading software and replacing the control module
WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2007 Volvo V70, 2006 Volvo V70, 2005 Volvo V70, 2004 Volvo V70, and 2003 Volvo V70. However, it is still accessible from the selected car via links, so may be relevant.
New software can be downloaded to the headlight control module (HCM).
When ordering software the vehicle's hardware and software are compared with Volvo's central database. If the comparison is correct the software is downloaded to the control module.
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.
For further information regarding downloading, see VIDA Design and Function, Downloading Software.
