Downloading Software And Replacing The Control Module

New software can be downloaded into the subwoofer module (SUB). 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's central database does not correspond, then the database is updated with the vehicle's configuration. When this is complete the software is downloaded.

The subwoofer module (SUB) is on the left-hand side in the cargo compartment.

After replacing the subwoofer module (SUB), the unique serial numbers of the control module are checked by the infotainment control module (ICM). The installed subwoofer module (SUB) will not work if the serial number is incorrect.

If a problem arises after software download and the control module does not work, try switching the ignition off and on.

Select the MOST network for a total download of software to the vehicle.
