System Overview: Signals
WARNING: This page is about a different car, the 2010 Volvo V70, 2009 Volvo V70, and 2008 Volvo V70. However, it is still accessible from the selected car via links, so may be relevant.
The table below summarizes the input signals to and output signals from the climate control module (CCM). The signal types are divided into directly connected signals, LIN and CAN communication. The graphic below displays the same information with the Volvo component designations.
