I don't know about the name "technet" in particular but there are services that aggregate technical service bulletins released by car manufacturers to make them more easily available to independent (non-dealer) mechanics.
It's more than just service bulletins. It aggregates service bulletins as well as common failures, steps to diagnose, and common repair procedures. Most of the data is via 3rd party repair centers as dealers quit sharing this data ages ago. Shops across the country use it to generate estimates and pay their techs. This ensures all work gets logged and that diags and standard procedures improve over time.
