V40 CEM Module, whats it for????

Hey guys,

I have some problems with my sidelights & foglights, after trying
everything I cannot find the problem.

Looking at the volvo wiring diagrams, the CEM module seems to be an
integral part of the lighting system. anybody have any experience of
problems with this unit, or even know for sure what it controls.

Regards

Lee.

 

The cem modul is "central electrik module"
i´ts where the car collects all information to send to the rest of the car.

But my experiens is that you probaly have problems whith the light switch.
where you have the on off button for the fog lights. take if off and smell
ad look for burning , where the cabel goes in in it. Sorry for my not so
good english
