Climate Control Module (CCM)

Downloading software and replacing the control module

New software can be downloaded into the climate control module (CCM). 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 entire climate control module (CCM) must be replaced as one unit.
A number of different customer parameters can be programmed into the climate control module (CCM). These customer parameters are stored in the control module but not in the Volvo central database. This means that the customer parameters must be reprogrammed when hardware or software is replaced.
For further information about programmable customer parameters, see: Diagnostic functions Diagnostic Functions
Customers can visit a workshop to set the darkness on the mirror. If, for example, you think that the mirror dims too much, it can be set slightly lighter and vice versa.
There are three setting levels, where the mirror is initially set to the intermediate setting.
