Antenna Control Module: Programming and Relearning
Downloading software and replacing the control module
New software can be downloaded into the antenna module (ATM) 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 control module is located in the rear section of the roof. Detach the headlining in the passenger compartment if the control module is replaced.
After replacing the control module, the unique serial numbers of the control module are checked by the infotainment control module (ICM). The
installed control module will not work if the serial number is incorrect.
Try turning the ignition off and on if there are problems after the software is downloaded and the control module is not working.
The MOST network is used for a total software reload.
