Description of components/functions activation

WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2007 Volvo V70, 2006 Volvo V70, 2005 Volvo V70, 2004 Volvo V70, and 2003 Volvo V70. However, it is still accessible from the selected car via links, so may be relevant.

Self-adjustment of damper motors 

This function can be used to carry out self adjustment of the limit positions for all the damper motors. Self adjustment must be carried out if, after checks, one or more of the damper motors do not reach their limit positions or the climate control module (CCM) is replaced. There are a number of possible reasons for a damper motor not reaching its end position. For example, the motor or the damper has been turned manually, the voltage supply may have been cut, or a component has been replaced.
