Cooling Fan Relay Service Program WVB-12
According to the description published today at

Radiator Cooling Fan Relay #2

Service Program Bulletin WVB-12
Pages: 7

Bulletin Description:
Subaru of America, Inc. (SOA) has determined that certain 2005-06 MY Subaru Legacy / Outback 2.5L M/T Turbo models require Radiator Cooling Fan Relay #2 replacement.

The original Radiator Cooling Fan Relay #2 installed on affected vehicles may create an electrical surge to the radiator cooling fan circuit within the Engine Control Module (ECM). The electrical surge may damage the ECM cooling fan circuit and cause the radiator cooling fan to run continuously whenever the engine is running.

This service program will involve replacement of the Radiator Cooling Fan Relay 2. It will also involve checking the ECM radiator cooling fan circuit for proper operation. If it is determined that the ECM radiator cooling fan circuit has been damaged, replacement of the ECM will also be necessary.
I guess SOA decided it was too expensive to wait around and replace ECUs as they broke and have opted, instead, to replace everybody's relay proactively.
