Hydraulic system
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.
Also new is that the rear wheels are also individually controlled which has meant that 2 valves per wheel have been introduced, 8 in total. If the system is supplied with Traction control or STC, 2 Hydraulic valves, 2 solenoid valves and 2 by-pass valve are installed. The control module is screwed into the ABS hydraulic modulator. The control module receives the wheel speed sensor signals which are put onto the network.
