Downloading Software And Replacing The Control Module
WARNING: This page does not describe the selected car, but rather 9 other vehicles, including the 2009 Volvo S60, 2008 Volvo S60, 2007 Volvo S60, 2006 Volvo S60, and 2005 Volvo S60. However, it is still accessible from the selected car via links, so may be relevant.
New software for the differential electronic module (DEM) can be downloaded. When ordering software, the hardware and the software in the car are compared to the data 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 control module is integrated in the coupling unit for the active on demand coupling (AOC). If the control module is replaced, the control valve/axial solenoid and oil pressure and temperature sensor must also be replaced.
