Downloading Software And Replacing Control Module: Notes
New software can be downloaded to the phone module (PHM). When ordering software the vehicle software and hardware are compared to Volvo's central database. If the comparison corresponds the new software is downloaded to the control module.
If the comparison between the vehicle and the Volvo central database does not correspond, the database is updated with the vehicle configuration, and then the software and any security codes (Security access code) is downloaded.
The phone module (PHM) is located above the glove compartment inside the dashboard.
