Downloading software and replacing the control module

New software can be downloaded into the transmission control module (TCM). When software is ordered the software and hardware of the vehicle are compared with Volvo's central database. If the comparison corresponds then the software is downloaded into 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.
