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
New software can be downloaded into the power seat module, left (PSL) and power seat module, right (PSR). 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. New software is downloaded after the update is complete.
A control module may already have software installed which will result in incorrect information being updated in the Volvo Central Database. To avoid this, tick the box in the VIDA (Volvo scan tool) software manager indicating the hardware has been replaced when the control module has been replaced.
If the control module has been replaced, the position of the seat must be initiated using a diagnostic function.
A number of customer parameters can be programmed into the power seat module, left (PSL) and the power seat module, right (PSR). 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 is replaced and when downloading software.
It is possible to reprogram the function so that the seat is automatically set by remote control. With this function activated the seat can be set using the remote control. This function is not available if it is deactivated.
