Well, I followed the instructions for replacing the relay in the CEM, in fact I tried two different relays
TYCO V23134-J52-X439 70A 12VDC and Potter & BrumfieldŽ 12VDC--70Amp Relay (VF7-11F12)
I checked both relays and they work there is continuity along the tracks and solder points, put everything back and still no power. No other functions are affected. No DTC in the ECU (used an xtool scanner checks all the modules) for any faults other than the light bulb for the key ring. I dont know if I should get another CEM and have it cloned or check with someone that has VIDA to see if they can scan for more info, Any input is appreciated
My issue (no power on passenger seat and front/middle cigarette lighter/2012 XC90) got fixed by replacing the relay on CEM under the hood. The model I used isManufacturer:
TE CONNECTIVITY
Manufacturer Part No:
V23134J0052X511-EV-CBOX
I can confirm when you lose power to both 12V sockets & Passenger seat, the Power relay in the CEM in the guide https://en.calameo.com/read/00098375906604c67c2f1 is the culprit. I just replaced mine and now it is all working. The hardest part of this is de-soldering the Relay from the PCB, but if you have a vacuum type de-soldering iron, it should be OK.
