S40 cem connections

Post by Ellyatts »

I have the 2006 s40 with no communication to cem showing on vita. P0023, P0020 and P0368
Car turns over, no start. Guessing due to leaking sunroof?? Took out cem, and going to clean and reinstall. Any tips? Should I just send out cem and replace?
Thanks guys

If there is water damage, you can disassemble CEM and check how deep damages, if it not so deep, try to clean and use, otherwise better to replace.

I order the “detox it” kit from eBay and plan to try cleaning first. Hope for the best fingers crossed 🤞
Thank you for quick response.
