Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Downloading Software And Replacing The Control Module
If necessary, new software can be downloaded into the suspension module (SUM). When ordering software, the hardware and the software in the vehicle is compared to the information in the Volvo central database.
If the comparison between the vehicle and Volvo central database does not correspond, the database is updated with the vehicle configuration. When this is complete the software can be downloaded.
After new software has been downloaded, the control module must be calibrated according to the diagnostic tool's vehicle communication.
