I don't believe you can install a used CEM, and you can install one yourself but it will need to be programmed. I would ask the dealer about installing a used one, I believe once the CEM has been programmed to a vehicle it belongs to that vehicle forever.

You can install a used CEM. A used CEM is already programed so you won't need to change anything. That is as long as your not getting a compatible one that hasn't been programmed. In that case you will have to have it programmed.

You can install a used CEM. I performed this installation using a CEM from an identical model in a salvage yard. The dealer wanted to charge $750 for a new CEM. I obtained the one from the salvage yard for $50. It works great and took about five minutes to replace.

Thank you for the corrections, this is great news for the people who need a new CEM.

For those questioning the replacement of their CEM with a used one, it is completely doable. The dealership told me I needed a new one after my driver's side low-beam went out. They also told me I could not use a used one because they're married to the car. If you think about it, all 2000 S40's were programmed the same way so to replace the CEM with another from the exact model shouldn't cause any problems. I picked one up off ebay. It is very easy to locate and took me about 20 minutes from start to finish. A total of 6 screws needed to be taken out. Location is under the steering column on the upper left side. You will see the sticker that says "C.E.M" and the part number. The number has since been replaced so don't be alarmed if you buy one with a different number. Just be sure it's the replacement number (you can ask the dealership for the numbers). Plugged the new one in and the light (and all other electronics) worked fine. Save myself $1,100.
