General Information - Design and Function: Component Locations Volvo S80 I

Location of components

The graphic shows the approximate location of the network modules. Modules A-E are slave modules while the others are master modules. The slave modules communicate through a master module using serial communication.

There may be more slave modules depending on the equipment level.

22. D: Roof Control Module (RCM)
23. E: Gear Selector Module (GSM)

Scheme 12

Previously each function had its own Control module, for example cruise control, alarm, turn signal lamps, rear demist and so on. On the P2X a function can be split between a number of modules, each of which has a particular task within the overall function. It is also possible to introduce more logic functions without needing more cables, connections and switches.
