High and low speed sides on the network

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 network consists of two parts. A high speed side which transfers (HS CAN) signals/messages between the central electronic module and the control modules in the engine compartment, and a low speed side (LS CAN) which transfers the signals /messages between the central electronic module and the control modules in the passenger compartment.

The interface between the high and low speed sides is supplied by the central electronic module which speeds up or slows down the communication between the two network sides.
