Yes, there has been a TSB (US Technical Service Bulletin) out for the
engine reprogramming for the occasionally reported stall incidents
(only fix if error reported to dealer), and I did expect that
eventually it would become a SSC (Special Service Campaign) which is
done pro-actively on vehicles so they don't experience any problems...
(There was a separate TSB that was replaced by SSC 40A, which then had
another TSB which was later replaced by SSC 40D, which then had another
TSB (EG047-04)...  It was only a matter of time before that became
another SSC...)

Anyhow, from the source:

model designation for the 2004-? Prius, Underhood carriage number =

Doing to apply annoyance, there is no excuse truly in everyone of
regular use, but making guide from the Toyota store, because it

Thanks!  Having been delivered in February, I suppose my Prius falls into
that time frame.  Have no idea where to look for the "undercarriage" number
but certainly my dealer can find it.  I'll whine next time they change my

 The "undercarriage" number is the VIN.  Only the last 7 digits (serial
number) are given on the Japanese site.

You can also check your month of manufacturer by looking at the VIN
plate on the driver's door jamb.  (Same place to look up your
exterior/interior color codes.)  At the top of the (black) plate, next
to Toyota Motor Corporation, at the top right corner is a date in MM/YY
format.  That's the month/year of manufacture of your Prius.

Thanks!  Ignoring all but the last seven digits (the others digits aren't
remotely similar) my VIN is slightly beyond the range of the third row

Toyota Announces Voluntary Special Service Campaign on 2004 and Early
2005 Model Year Prius
10/13/2005 Torrance, CA
Toyota Motor Sales (TMS), U.S.A., Inc., will launch a Special Service
Campaign involving certain 2004 and early 2005 model year Prius sold in
the U.S.

On the involved vehicles, an issue with the program logic in the
Electronic Control Module (ECM) system may cause some or all of the
following warning lights to illuminate: Master, Hybrid System, Engine,
Vehicle Stability Control, and Brake. If this occurs, the vehicle will
enter a "fail-safe" mode which allows limited operation via the
electric motor. However, the electrically-powered brake and steering
operation will continue to function normally if this condition occurs.
The electric motor will also provide enough power to allow the driver
to pull the vehicle over and away from traffic. Once the vehicle is
stopped, the driver may be able to restart the gasoline engine in the
vehicle by pushing the start button.

Approximately 75,000 2004 and 2005 model year Prius vehicles may be
affected by this condition. Toyota is proactively conducting a campaign
in the interest of its customers.

Toyota will inform owners of the involved vehicles with a Special
Service Campaign notification letter sent via first class mail
beginning in late-October. Owners are requested to contact their local
Toyota dealer for diagnosis and repair upon receiving their
notification. Toyota will reprogram the ECM system at no charge to the
owners of the vehicle. Also, in certain vehicles a special dielectric
grease will be applied, at no charge, to a connector for the transaxle,
which may cause a similar condition.

Customers with questions or concerns should contact the Toyota Customer
Experience Center at 1-800-331-4331.
