Yes, at: http://www.selidori.com/tech/prius/DOC/ There are separate versions for 2004-2005 and 2006-2009. The 2010 version appears to be the User Manual, not the Technical Manual. JeffD
You might find some free resources online (like wiring diagrams or partial manuals), but full versions are usually paid or require subscription access. If you’re planning to do your own work, your best bet is to get proper toyota Repair manuals(dot)com(PDF). They give you complete repair steps, diagrams, and specs so you’re not stuck relying on the dealership for everything.
Presuming that you remove the spaces and replace (dot) with a period, that link resolves to a dodgy looking Indonesian gambling site. Best edit this post to remove that link.
Looking at the links in the other post, they both report that the sites are not secure. Maybe these should be reviewed by @jdenenberg and @krg03?
