V50 2006 1.6D CEM errorcodes.

Post by SvenR » Mon Jun 10, 2019 11:08 am

Hello.

Have friend car error codes:
V50 2006.

CEM-DE23 Communication with TRM control module Signal missing

CEM-DE43 Communication with DDM control module Signal missing

CEM-DE45 Communication with PDM control module Signal missing

CEM-DE58 Communication with SRS control module Signal missing

CEM-9A02 Interior lighting Signal too low

Will CEM contacts cleaning help or are CEM faulty?

With so many errors, I'd check first if the electronics are getting enough battery power.

Deleted errors and checked with working engine again but same. Found from internet that SRS and other messages on display, cleaning will help. Have in my V70 P2 also lot of CEM error codes but there I also no power on nr.15 fuse what is known issue on that CEM-L. But can´t find information for that car CEM. Xemodex write that all module lines are in that car possible known weak spots. Think that will fist clean connectors and see if that will help, if not then need buy other CEM.
