High And Low Speed Sides On The Network

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.
