When does a CEM need programming? 2001 Volvo S60 Topic is solved

Alexis2929 · Post by **Alexis2929** » 19 Apr 2019, 17:23

A part inside my CEM is broken (the CSH1 and CSH2 connector , it’s a little black box) and I don’t have any power in my left turn signals

is it possible to get a new “connector” and if so what are they called, and saughter it back to the CEM.

If I were to buy a CEM would I need to program it to my car or would they already be programmed and thus I could just swap out the old one for the new one. Without needing any extra work (programming) to the CEM that I buy

I’m just looking for the cheapest and easiest way to fix

Does it need to be the exact same serial numbers ?

Any help is appreciated Thanks

CEM contains key information and car configuration all which are unique to your car. Basically it won't start if you swap it out.

They can be re-programmed by XeModex but they'll need the original as well as the donor.
