How do you mean check power?

Edited the photo and added a new just to show what I have meassured so far. I would say that most point to the SHM. How do you mean that this can cause the CCM to missbehave?

First check if you have power on these fuses.

SHM is controlled by the same LIN bus that used to control damper motor so when SHM is faulty it
often cause noise on that bus so CCM cannot control damper motors properly.
If you have questions about Volvo firmware ask me. I may know an answer :)

Fuses F1,F2,F16 has no power (voltage) but are funktional fuses, not broken. Feels sad and also bad. I hope that it isnt the CEM that has gone bad on me cause then this is going to become a nightmare.

CEM is bad I think. But if you know how to use solder that is doable.
You need just to replace a relay.
I think you know what to say to volvo engineers that created 'such a good' design. :)
Instead of creating replaceable relays they 'just' soldered them inside.

Yeah I know how to use a solder-iron. Fixed the DIM on the old car and some more. But are they not sealed with some kind of compouned inside? Are they normal relays soldered inside or are they special, special???

I replaced the fuses just incase and the light beam adjustment LSM (F16 CEM) is now working that was not working before even though i meassuered the fuse and it wasnt broken. Still no heat seat though I replaced them aswell.

And where do I get them from, if you have any idea? Dont have any partnumber, no nothing. Is it a bad idea when I have all apart to reflow/resolder all components due tue issues with 1999-2003 had in DIM? Im pretty sure that I also will need new software in CEM after this and perhaps other modules aswell?
