You can find TSB's for most vehicles at the following link. There aren't any listings on the 2004 Prius yet.

AllData is WAY behind the real world.

You want real info?

techinfo.toyota.com

(no www.)

There are numerous TSB's for the 04.

That's why Alldata is known as either "Somedata" or "Nodata" in the repair trade. BTW they're part of "Autozone".

 

You want real info?

techinfo.toyota.com

techinfo would be a good link, but why does it cost $10 for a day pass?

 

Because what's good ain't free, and what's free ain't good!

Car manufacturer's service info websites are designed for independant repair shops to access the same info dealer techs do.
Toyota's is one of the best and the least expensive.
Volvo's site is $6000 a year plus $$ PER DOWNLOAD.

 

when people get ahold of them, they are often posted at:

I don't think it's complete. the last techinfo TSB dump that I was given was in Jan/Feb. of 2004.
