Downloading software and replacing the control module

New software can be downloaded into the passenger door module (PDM) and the driver door module (DDM). When ordering software, the hardware and the software in the car is compared to the information in the Volvo central database. If the comparison is OK the software is downloaded to the control module.
If the comparison between the car and Volvo central database is not OK, the database is updated with the car configuration. When this is complete the software is downloaded.
The window positions must be initialized again after replacing the control module. This is so that the new control module stores the closed position of the window. Initialization is carried out using the diagnostic tool.
If the vehicle is equipped with power seat with memory function for external rear-view mirrors (only C70), this function can be turned off.
This means that it is possible to deactivate personal setting of external rear-view mirrors depending on which remote control unlocks the vehicle.
Deactivation is performed with the diagnostics tool.
After deactivation, this setting will be stored in the control module, but not in Volvo's central database. This means that deactivation must be performed again when a new hardware replacement is carried out.
