Volvo BCM / CEM Services
The Volvo CEM (Central Electronic Module) is the body control / fuse box / immobilizer master on most Volvo P2 (S60 / S80 / V70 / XC70 / XC90) and P1 / P3 (S40 / V50 / C30 / C70 / S60 / V60 / XC60 / S80 / V70) platforms. CEM failure is one of the most common Volvo electronic issues. We perform CEM clone work on the bench for many model years.

Not Sure Which Service to Choose?
If you are unsure which option matches your Volvo module, the safest path is to email or text us photos before ordering: full label of the original module (the one you want serviced), full label of the donor module if you already have one, the part number, hardware revision, and software/calibration sticker, and a photo of the connector pinout if visible. We will confirm whether the service is supported for your specific part number and hardware revision before you order and ship.
Compatibility Warning
CEM cloning requires a donor of the same part number prefix and same hardware revision. P2 vs P1 vs P3 CEMs are not cross-compatible. S40 / V50 / C30 / C70 share a CEM family; S60 / S80 / V70 / XC90 share another. Send photos before purchasing a donor.
What to Ship
- Your original Volvo module (the failed/locked unit), clearly marked “ORIGINAL”
- If applicable: a donor module, clearly marked “DONOR” — same part number family and hardware revision as the original
- Your order receipt printed, or order number written on a slip in the box
- Your return shipping address
- Ship to the address shown on your order receipt at checkout (we operate from 2 locations and route based on tool availability and turnaround)
