Downloading software and replacing the control module

New software can be downloaded to the Central electronic module (CEM).
When ordering software the vehicle's hardware and software are compared with Volvo's central database. If the comparison is correct 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.
For further information regarding downloading, see Design and Function, Downloading Software.
The position sensor for headlamp range adjustment must be calibrated when the control module is replaced. Calibration must also be carried out when replacing the position sensor for headlamp range adjustment. This is carried out using the diagnostic tool via the vehicle communication input.
