It's been a long time coming. Volvo has kept software under wraps for a long time, but has finally made it public. Hope this helps those of you in the ECM swap process.

Taken from the bulletin:

DESCRIPTION:

It is now possible to reuse a programmed ECM (Engine Control Module). This was earlier

impossible due to vehicle unique Immobilizer codes. Benefits for this feature are several:

SERVICE:

NOTE! Immobilizer codes can only be erased with VIDA in the same car as ECM

was programmed for. To erase, follow these steps:

- Connect vehicle to VIDA and choose Software Manager.

- Order Software Product, P/N 8691406 for P2 cars

- Order Software Product, P/N 8691430 for P1 cars

- When software is available, download to vehicle.

ECM is now "virgin" and can now be swapped with another vehicle or used later.

NOTE! Sometimes the car may start, even though the "erase" SW has been downloaded.

This is no error, and it will still be possible to do a ECM reload in another car.
