Toyota offers paid public access to online repair manuals:
"Toyota offers easy and immediate access to many service publications on-line through the Technical Information System (TIS). TIS is available to the public through a subscription at http://techinfo.toyota.com.
Subscriptions to this information service can be purchased for daily, monthly or annual access. TIS provides access to all of the key service, maintenance, and reference publications necessary to support Toyota vehicles including:
Collision repair manual
Electrical wiring diagram
Technical Service Bulletins (TSB)
Information is generally available for U.S. market vehicles starting from the 1990 model year, but specific information can be found in the TIS Library Content table. Please note that this site does not include any part catalog, ordering, or application information.
The information found in TIS is presented in PDF format and requires the Adobe Acrobat®viewer for viewing and printing."
The $10 for 24 hr. access could be useful for those who would like to perform their own maintenance/repairs. I'm not sure how cost effective this would be over the long run compared to purchasing printed copies of the repair manuals.
