System overview: Signals
WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2006 Volvo S80, 2005 Volvo S80, 2004 Volvo S80, 2003 Volvo S80, and 2002 Volvo S80. 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.
