Replacing Control Module
WARNING: This page is about a different car, the 2010 Volvo V70, 2009 Volvo V70, and 2008 Volvo V70. However, it is still accessible from the selected car via links, so may be relevant.
The control module is located under the right front seat.
After replacement of the audio module (AUD), the infotainment control module (ICM) checks its unique serial number. If the serial number is incorrect, the audio module (AUD) will not work. If the problem remains after software download, try switching the ignition off/on.
Select the MOST network for a total download of software to the vehicle.
