Changing the driving mode (non R line)
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.
There are two driving modes in the suspension module (SUM). These driving modes are changed via a switch on the lower section of the climate control module (CCM).
The signal is transmitted from the climate control module (CCM) via the control area network (CAN) to the central electronic module (CEM). The central electronic module (CEM) sends the signal on to the suspension module (SUM).
The climate control module (CCM) always remembers the driving mode which was selected last and stores it after each operating cycle.
